    Leave a Comment

    Industrial blowers and fans move high volumes of air or gas throughout a facility. Blowers rely on impellers to accelerate and direct large volumes of air to a localized area. Here, we will discuss the various types of industrial blowers, as well as their benefits and applications, to help you determine if industrial blowers are right for your application.

    What Are Industrial Blowers?

    An industrial blower relies on an electric motor, impellers, and airfoils to efficiently increase the airflow in a workspace. Blowers can use positive displacement, axial, or centrifugal technology to move air. This increased airflow removes particulates, dirt, dust, and other contaminants from the air. Industrial blowers are designed to be permanent additions to a workplace and offer higher pressure than fans.

    Industrial blowers move gas and air for exhaust, ventilation, conveying systems, aspiration, and cooling. Blower designs include numerous blower types, operating pressures, electrical ratings, and dimensions, and they can be customized to perform various functions. Industrial blowers can also be used for dust control, fluid bed aerators, and drying.

    Industrial blowers provide the following benefits:

    • Safety. Industrial blowers operate with a reliable and safe electric motor.
    • Pressure. Industrial blowers can move large volumes of air at high speeds, resulting in low to medium static air pressure.
    • Dust Collection. Industrial blowers can be equipped with a bag or filter to catch dust and other particulates.
    • Humidity Control. Proper airflow eliminates dampness that can cause odors and mold growth.
    • Healthy Environment. Industrial blowers remove particles from the air that can irritate workers’ eyes, noses, and respiratory systems.
    • Air Movement and Control Association (AMCA) Standards. AMCA classified blowers are suitable for various applications, including moving dangerous fumes.
    • OSHA Requirements. Industrial blowers help create a healthy work environment as required by OSHA.
    • Control Smoke and Fumes. Blowers can remove and exhaust fumes and smoke from the work environment.
    • Ventilation. Blowers provide airflow essential to cooling and reducing harsh conditions.
    • Durability. Industrial blowers are able to operate in harsh conditions and endure stressful work environments.
    • Adaptability. They are suitable for various applications with custom configurations, designs, and dimensions.

    Types of Industrial Blowers From Markair

    At Markair, we deliver industrial blowers from the leading brands. The axial fan is one of our most popular products and is the textbook example of a fan. It has a central hub with several blades that extend from it radially. The fan blades rotate to draw air in and force it out the other side parallel to the rotational axis. Axial fans are suitable for many general-purpose applications with low pressure and high flow rate and come in many designs.

    We also offer the centrifugal fan. A centrifugal fan has a central hub with several blades at a right angle. Sometimes called a blower, a scroll-shaped structure houses the fan assembly. It increases the incoming pressure of the air or gas and forces it in another direction. The flow rates of centrifugal fans are lower than axial fans, but the pressures are higher. We can alter the design to change the performance of the centrifugal fan, creating different pressures and airflow.

  2. Axial vs. Centrifugal Fans: Which Is Best for Your Application?

    Leave a Comment

    Industrial fans circulate large volumes of air in warehouses, factories, and other industrial environments. Available in several sizes and designs, most fans can be categorized as either axial or centrifugal based on their method of operation. Understanding these two fan types and the distinct benefits they offer is essential when choosing a fan for an industrial application.

    Here is an overview of axial and centrifugal fans, including their design, performance characteristics, benefits, and applications for which they are best suited.

    Axial vs. Centrifugal Fans

    Axial and centrifugal fans are both composed of the same key parts, but they can be distinguished by the following characteristics.

    Axial

    Axial fans consist of a motor, rotor, and several blades, all of which are housed within a durable casing to protect against dust and debris. Each blade extends radially from the center of the rotor hub. Powered by an electric motor, these blades rotate around a fixed axis and force air outward in a direction that is parallel to the axis.

    Benefits and features of axial fans include:

    • Compact design: Axial fans feature a compact, lightweight design that allows for fast and easy installation.
    • High flow rate: Using a relatively small amount of power, axial fans generate air flow with a high flow rate and low pressure. This makes them extremely efficient at moving large volumes of low-pressure air from one location to another.
    • High operating speed: Axial fans have a higher peripheral speed than their centrifugal counterparts.
    • Customizability: The size and shape of the fan blades can be customized depending on the air volume and speed requirements of the application.

    Centrifugal

    Often referred to as blowers, centrifugal fans feature a fan assembly enclosed within a scroll-shaped casing. In contrast to axial fans, the blades of a centrifugal fan are positioned at right angles to the rotor axis. The fan compresses the incoming air, then forces it out in a direction perpendicular to the rotor’s central axis.  

    Benefits and features of centrifugal fans include:

    • High-pressure airflow: While centrifugal fans generally achieve a lower flow rate than axial fans, they can generate much higher pressures and steadier airflow.
    • Low maintenance: Centrifugal fans can be equipped with self-cleaning features that make them easy and inexpensive to maintain.
    • High efficiency: Although centrifugal fans consume more electricity, their creation of constant airflow is generally more energy-efficient than axial fans.
    • Versatility: Centrifugal fans are capable of handling various airflow conditions and can be sized to accommodate a range of spaces.
    • Durability: Made from durable materials, centrifugal fans are built to withstand corrosive or high-heat industrial environments.

    We carry these centrifugal fans:

    • Forward Curved: Characterized by several small, forward-curved blades, forward curved fans are a lightweight and cost-effective centrifugal option for industrial applications.
    • Backward Curved: In contrast to forward curved fans, backward curved fans utilize several large, backward-curved blades. While heavier and more expensive than forward curved designs, these fans are generally more durable and efficient.
    • Backward Inclined: Backward inclined fans are equipped with flat, backward-inclined blades to reduce interference and improve efficiency.
    • High-Efficiency: High-efficiency centrifugal fans are designed to move high volumes of air in large-scale industrial applications.
    • Airfoil: Using aerodynamic airfoil-shaped blades, airfoil fans achieve high levels of efficiency while minimizing power consumption and noise.
    • High-Pressure: High-pressure centrifugal fans provide low flow and high static pressure in continuous-use industrial applications.
    • Induced Draft (ID): Induced draft fans are often used in combustion systems to remove air from a specific area, creating a vacuum or negative air pressure.
    • Forced Draft (FD): In contrast to induced draft fans, forced draft fans create positive air pressure by pushing air into a system.
    • Plug: Featuring a compact, easy-to-install design, plug fans are used to circulate air in small air-handling units and other confined spaces.
    • Plenum: Plenum fans feature a centrifugal wheel without the full housing found in most standard centrifugal fans, allowing them to distribute airflow in multiple directions. These fans are known for their high efficiency and relatively quiet operation.
    • Utility Sets: Available in various configurations, centrifugal utility fan sets are ideal for lighter-duty industrial applications.
    • Inline: Often used in industrial and HVAC applications, inline centrifugal fans are designed to be mounted inside the ductwork to improve efficiency.
    • Mixed Flow: Mixed flow fans combine the efficiency of axial fans with the pressure-generating capabilities of centrifugal fans.
    • Fume Exhaust: Fume exhaust fans are designed to safely exhaust noxious or high-temperature fumes in a range of industrial applications.
    • Laboratory Exhaust: Commonly used in universities and research facilities, laboratory exhaust fans allow hazardous chemicals, fumes, and contaminated air to be quickly and safely removed from indoor spaces.

  3. What Is Industrial Ventilation?

    Leave a Comment

    Installing an industrial ventilation system is a top priority for companies in a wide variety of fields. A good industrial ventilation system can remove air contaminants, filter out dust fumes, and bring in fresh air, which can help employees avoid sickness and heatstroke in addition to reducing the risk of fire or explosion. Due to their complexity, designing an industrial ventilation system that can filter out industry-specific contaminants while remaining reliable and corrosion-resistant can present a challenge for manufacturers and technicians in any field.

    At Markair, not only do we provide the best industrial ventilation and dust collection technology, but we also offer expert applications support for power generation, water and wastewater, pulp and paper, general manufacturing, and food manufacturing facilities. Keep reading to learn more about industrial ventilation systems and their major components, why they are important, and how Markair can help solve unique ventilation problems associated with complex systems.

    What Is An Industrial Ventilation System?

    Industrial ventilation systems are designed to move a specific amount of air outside a facility (which is called the “exhaust”) while bringing in an equal amount of air from outside the facility (which is called the “supply” or “intake”) at a specific velocity. This process results in the removal of airborne contaminants, such as dust, ash, and chemicals, that can be hazardous to humans if inhaled.

    Ventilation system

    Although all ventilation systems are designed following the same basic principles, each system is carefully custom-designed to handle the specific type of work occurring at a given workplace, as well as the rate at which specific contaminants are released. For example, facilities with low-toxicity contaminants and a minor degree of air pollution may rely on dilution ventilation, in which contaminated air is mixed with clean air to reduce the proportion of contaminants. In contrast, facilities with more toxic contaminants may use local exhaust ventilation, in which fume hoods are used to capture contaminants at their source and carry them away from workers.

    Importance of Industrial Ventilation Systems

    Some of the main benefits of industrial ventilation systems include:

    • They eliminate hazardous chemicals or materials. Inhaling dust, ash, particulate matter, or chemical fumes can cause serious health complications for workers, especially over long periods of time. Reducing the concentrations of toxic chemicals or materials in the air that employees breathe can minimize their risk of illness or harm.
    • They eliminate the need to use less toxic chemicals. Because some industries rely on the use of toxic chemicals and materials, an effective ventilation system can allow manufacturers to continue using them without needing to account for the fact that they can be harmful to their employees’ health and safety.
    • Installing ventilation is easier than changing an industrial process. Ventilation removes the need to redesign an industrial process that may work well but produce more contaminants than desired. Additionally, because ventilation helps remove dust and particles that can accumulate on machinery, it can help prolong the lifespan of expensive industrial equipment, thus allowing effective industrial processes to continue for longer amounts of time.
    • Installing ventilation can remove the need to change work practices. In addition to allowing efficient industrial practices to continue unabated, installing ventilation can help manufacturers save time and money by keeping employees healthy, thus reducing the amount of sick time used. Ventilation systems also keep machinery in good condition, which reduces the amount of downtime spent fixing damaged

    One additional benefit of ventilation systems is that they can help control the temperature of a warehouse or factory. This temperature control can help improve workers’ health, safety, and well-being by providing them with a workplace that is cool and comfortable rather than dangerously hot or stuffy.

    Parts of Ventilation Systems

    To fully comprehend how an industrial ventilation system works, it is important to understand some of the main parts of common industrial ventilation systems. As stated above, most ventilation systems include an air supply system (which brings fresh air inside) and an exhaust system (which removes contaminated air). The main parts of the air supply system include the following components:

    • Air inlet. The air inlet represents an entry point for the clean air that is brought into the building. The size, location, and control of the air inlet must be strategically determined to provide a given building with optimal airflow (i.e., the ideal quantity of fresh air and optimal velocity).
    • Air filtering equipment. Air filtration equipment is used to remove contaminants from the air before it is brought indoors. These filters should be selected based on the size of particulate matter that needs to be filtered out. Filters should be regularly cleaned or replaced to ensure that air is being adequately filtered and to avoid contaminant build-up.
    • Heating and cooling equipment. Heating and cooling equipment ensures that the humidity and temperature of the air remain appropriate for both the facility itself as well as the work being done inside it. Maintaining the temperature of the facility is crucial for the comfort of workers as well as the optimal performance of machinery. Maintaining the facility’s humidity also prevents the formation of condensation, which can damage equipment.
    • Fan. Fans are used to keep air circulating as well as to direct its movement in a specific direction and at a specific velocity. The shapes of each fan blade can be customized to provide less noise, allow for faster airspeeds, or move greater volumes of air. As with air filtering equipment, fan blades must be kept clean and in good condition to ensure that they continue to provide optimal service.
    • Ducts. Ducts are the series of passageways through which clean air is brought into a facility. An ideal duct system should be able to carry air without depositing any of its particulate material within the ductwork while also requiring as little fan horsepower as possible and experiencing minimal loss in pressure during its movement.
    • Air distribution registers. An air distribution register not only allows clean, filtered air to be directed into a specific area of a facility, but it also includes a damper to control the volume of air being carried into that area. Registers also include blades that can be modified to direct air in a specific direction or to a specific location to maximize the efficacy of the ventilation system.

  10. Aerovent Fans: A Sure Bet on the Trump Casino Vessel

    Leave a Comment

    Trump Casino

    Atlantic Marine, the shipbuilder, wouldn’t gamble on just any fan product. Atlantic Marine worked with Markair, Inc. to purchase Aerovent fans, thereby eliminating delays in approval, and maintaining their design integrity in providing their customers with a quality product and on-time delivery.

    In all, forty-two Aerovent Type “W” Direct Driven Vane axial

    Fans were supplied for the Trump Casino vessel project.

    Lay Pitman & Associates, the naval architect, uses our computer fan selection program along with the expertise of Markair engineers to specify the Aerovent equipment, to select the quietest sound levels, provide stable fan curves, and determine adjustable pitch fan blade angle settings.

    For this project, fan sizes range from 18″ to 33″ diameter, powered by both single speed and two speed motors designed to meet the weatherproof requirements for IEEE 45 and USCG 259 marine-duty, below-deck service.

    Aerovent’s Type “W” vane axial fan was chosen for this project based on its proven performance and reliability on several other passenger vessel projects where Aerovent marine-duty vane axial fans have been installed.

    The Type “W” vane axial design provides both the engineer and ship owner a simple, yet very versatile fan for shipboard uses.

    What makes the Type “W” vane axial the right fan for the job? We think there are five advantages:

    Wide Performance Range: Performance requirements for the Trump Casino project varied from 1800 CFM to 20,000 CFM with up to 2″ of static pressure. Direct drive Type “W” vane axials are available from 18″ to 84″ diameter, 1200 CFM to over 200,000 CFM and up to 4″ of static pressure.

    Compact Design: Fan housing lengths are usually equal to or less than the fan diameter keeping installation space to the bare minimum. The available space for mechanical equipment is always a major design consideration especially on luxury passenger vessels.

    Quiet Operation: Due to the fan’s close proximity to sleeping quarters, restaurants and public areas, the allowable noise levels from the fan are very stringent. The Type “W” vane axial is known for its smooth, stable performance and quiet operation.

    Manually Adjustable Fan Blades: Adjustable aluminum fan blades make it possible to alter the airflow during final balancing of the supply/ exhaust system.

    Rugged Steel Housing Construction: Heavy gauge flanged housings are built for bulkhead mounting. For ease of installation, the motor leads are extended to the exterior of the fan casing for making all electrical connections.

    The complete order was shipped three days ahead of schedule. In a letter from Atlantic Marine’s Mr. George Haynes to Markair, he states, “We certainly appreciate vendors who can help us meet our production schedules and furnish quality products.”
