Metalworking & Fabrication

Metalworking and fabrication operations demand clean, well-ventilated workspaces to maintain safety, product quality, and equipment reliability. From welding and grinding to cutting and polishing, these facilities generate a wide range of airborne contaminants that can compromise worker health and damage sensitive machinery.

Markair, Inc. works closely with fabrication shops and metalworking facilities to deliver effective air handling solutions that directly address these challenges. Our dust collection systems help maintain safe working conditions and reduce maintenance costs by controlling hazardous dust, fumes, and heat.

Metalworking processes—particularly grinding, sanding, and welding—release fine particles that pose serious health and safety risks. Dust from materials such as steel, aluminum, and titanium can accumulate quickly and may become combustible under certain conditions.

Markair’s dust collection systems are engineered to capture these particles at the source. We provide cartridge-style collectors, wet scrubbers, baghouse systems, and localized capture hoods depending on the specific needs of the application. Our systems reduce airborne dust, help facilities comply with OSHA and NFPA regulations, and support a cleaner production environment.

Whether you operate a large-scale fabrication plant or a compact welding shop, we configure dust collection solutions that match your equipment layout, airflow needs, and production schedule. Each system is sized and specified based on real-world usage and operational priorities.

Thermal spraying is widely used in metalworking to apply protective or functional coatings onto surfaces using molten or semi-molten materials. Common techniques include arc spraying, flame spraying, and plasma spraying, each of which generates high volumes of fine metal particulates and overspray.

These airborne particles (often composed of metals like nickel, chromium, or aluminum) pose serious health and safety hazards. Without effective dust and fume control, thermal spray operations can quickly lead to combustible dust buildup and harmful worker exposure.

Markair’s dust collection systems are ideally suited for managing these risks. We offer high-efficiency filtration systems, including wet and dry collectors, that are capable of capturing ultra-fine thermal spray dust at the source. Integrated hoods and extraction systems help isolate the spray zone while maintaining proper airflow and minimizing the spread of contaminants.

By controlling thermal spray emissions, we help facilities maintain OSHA compliance, reduce fire and explosion risks, and extend the service life of nearby equipment.

Heat and fumes are common byproducts in fabrication facilities. Without proper ventilation, these conditions can create uncomfortable—and sometimes hazardous—work environments. Markair provides industrial ventilation services that support proper airflow and fume extraction across a wide range of processes.

We design and install:

• General building ventilation for high-bay and enclosed areas
• Local exhaust systems for weld stations and CNC machinery
• Make-up air systems that balance internal pressure and maintain indoor air quality
• Energy recovery units that reduce HVAC load and operating costs

Our team evaluates each facility to determine the most effective way to move and filter air. Whether the goal is to meet code, reduce energy use, or improve operator comfort, our systems deliver measurable results without disrupting day-to-day operations.

Markair supports metalworking facilities with custom fabrication services that include:

• Precision ductwork and plenum fabrication
• Custom-built air handler assemblies
• Sheet metal enclosures and transition pieces
• Fan skids and hood assemblies
• Rebuild services for damaged or aging ventilation equipment

We adapt system components to meet spatial constraints and integrate with existing production equipment. These customizations help reduce downtime during installation and extend the life of critical infrastructure.

From initial concept to installation, Markair offers full-service project support. We provide site visits, airflow analysis, system layouts, and budget planning. Our team works directly with facility managers, contractors, and engineers to keep projects on track and compliant with safety codes.

Turnkey installation is available for both new construction and retrofit projects. Our coordination with mechanical and electrical trades helps ensure that installation is efficient and meets project deadlines.

Markair’s industrial ventilation services and dust collection systems help fabrication shops meet local and federal safety regulations. Our systems support compliance with OSHA permissible exposure limits and NFPA combustible dust guidelines. Beyond regulatory needs, clean air contributes to better employee retention, fewer equipment failures, and reduced maintenance.
