Axial Flow Fan for Welding Booth Ventilation — Manufacturer & Supplier
Vayuvents Pvt. Ltd. manufactures and supplies axial flow fans for welding booth and workshop ventilation across fabrication shops, auto component plants, shipyards, and structural steel manufacturers in India and export markets.
Welding fumes contain metal oxides, manganese, chromium, and nickel compounds classified as hazardous under Indian Factory Act regulations. Exposure without adequate ventilation leads to occupational lung disease, siderosis, and manganism — serious long-term health conditions.
Axial flow fans in welding booths create a continuous cross-draft that carries welding fumes away from the welder's breathing zone. The fan creates a directed airflow path from fresh air supply on one side to fume exhaust on the other, maintaining clean air at the work surface.
Vayuvents sizes welding booth fans to achieve the minimum face velocity of 0.5 m/s across the booth opening as specified in IS 3016 and Factory Inspector guidelines. Both portable and fixed fan configurations are available.
How It Works in This Application
Fresh Air Entry
Fresh air enters through a supply opening, creating airflow that sweeps across the work surface from behind the welder toward the exhaust side.
Fume Capture in Airstream
Welding fumes generated at the weld pool are immediately captured in the cross-draft airstream, preventing them from rising into the breathing zone.
Fume Transport to Exhaust
The contaminated airstream carrying welding fumes and smoke is drawn through the axial fan at the exhaust side of the booth.
Filtered or Direct Exhaust
In open booths, contaminated air is exhausted directly to atmosphere. In enclosed booths, a filter unit upstream of the fan captures particulates.
Recommended Variants
Wall-Mounted Axial Exhaust Fan
Direct wall-mounted exhaust fan for fixed welding bays — simplest and most common configuration.
Most RecommendedPortable Fume Extraction Fan
Mobile axial fan on a wheeled stand for flexible positioning at different welding workstations.
Belt Driven Axial Fan
Motor outside the fume airstream — recommended where welding fumes are acidic or corrosive.
FRP/SS Axial Fan
FRP or SS304 construction for stainless steel welding where chromium fumes cause corrosion in standard MS fans.

FAQs
IS 3016 guidelines recommend a minimum face velocity of 0.5 m/s at the booth opening to capture welding fumes. For a standard 2m x 2m welding booth opening, this requires approximately 7,200 m3/hr. For heavier welding processes, higher velocities of 0.75 to 1.0 m/s are recommended.
Exhaust-only is the most common and recommended approach — the fan exhausts fume-laden air from the back of the booth while fresh air enters from the front around the welder. This creates a cross-draft that pushes fumes away from the breathing zone.
No. Standard domestic fans are not rated for the acidic, particulate-laden welding fume environment. Industrial-grade axial fans with epoxy-coated or SS construction, IP55 motor, and IS-compliant airflow capacity are required.
For stainless steel welding, fumes contain hexavalent chromium and nickel compounds which are highly corrosive. SS304 or FRP fan construction is recommended. A HEPA filter system is also recommended downstream.
Yes. Vayuvents supplies axial fans sized to work with filter media units in enclosed welding cabins. The fan is installed downstream of the filter to handle only cleaned air, extending fan service life.
Welding booth axial fans should be inspected monthly for fume deposits on the impeller which can cause imbalance. Impeller cleaning every 3 to 6 months is typical, with motor bearings checked annually.
