Overhead track-mounted FR vinyl curtain systems that enclose the volume above welding stations, directing welding fumes toward the extraction system rather than allowing them to disperse into general building air. Weld fume curtains improve extraction efficiency and help facilities meet OSHA 1910.252 fume control requirements by keeping the fume plume within the capture zone of the extraction equipment.

Weld fume curtains address a specific problem: fume extraction equipment that cannot capture enough of the generated fume plume because the welding area is open to the building volume. Curtains enclose the fume zone so extraction equipment works as designed.
Enclosing the overhead volume above a welding station dramatically reduces the air volume the extraction system must process — allowing the same extraction equipment to achieve significantly higher capture efficiency without increasing airflow.
OSHA requires fume control at the source for welding operations. Fume curtains in combination with extraction equipment improve source-capture performance to levels that ductwork and extraction arms alone cannot achieve in large open bays.
Overhead track systems are designed to slide or stack open for overhead crane and forklift access during part loading and unloading — then close during active welding to restore fume containment without disrupting production flow.
Curtain panels use FR-certified PVC vinyl rated for welding environments — resisting ignition from weld spatter at operating distances and maintaining integrity in the heat and UV environment of the welding area.
Track systems are engineered to span any bay width and follow any bay geometry — including L-shaped and irregular bays. Curtain panels configured to the span and opening requirements of each specific installation.
Opaque curtain materials are available for applications where the fume curtain must also block UV arc radiation from escaping the welding area — providing both fume containment and arc flash protection in a single overhead curtain system.
Weld fume curtain systems from Modular Solutions are engineered to the specific bay dimensions, extraction system, and production access requirements of your welding operation.
Heavy-duty overhead track hardware with smooth-rolling panel carriers allow curtain panels to slide fully open to one side for crane and forklift access, then close manually or with a pull-cord system during welding.
Large bay openings use multiple curtain panels stacking to one or both sides — keeping the stacked footprint minimal and maximizing the open bay width for equipment access.
Curtain track systems are designed to coexist with fume extraction arm installations — with arm mounts and track routing coordinated so extraction arm coverage is not reduced by curtain panel positions.
Curtain panels with floor-level skirts close the gap between the bottom of the panel and the floor or work platform — improving containment in low-bay configurations or where the welding position is below the curtain track height.
Clear and translucent curtain materials maintain supervisor sighting lines and natural light transmission through the curtain area while still substantially reducing fume drift to adjacent work areas.
Stainless track hardware and corrosion-resistant fittings available for welding environments with coolant mist, washdown cleaning, or high-humidity conditions.
Weld fume curtain systems are specified when extraction equipment alone cannot achieve adequate fume capture due to open-bay welding configurations or large welding volumes.
Representative system parameters — all specifications are engineered to your bay dimensions, extraction system, and access requirements.
A weld fume curtain system is an overhead track-mounted curtain that encloses the volume above a welding station, directing welding fumes toward the extraction system rather than allowing them to disperse into the general building air. Fume curtains work in conjunction with fume extraction equipment — they are not a substitute for fume extraction but improve extraction efficiency significantly.
No. Weld fume curtains are a containment and capture enhancement, not a replacement for fume extraction. Curtains enclose the fume plume zone so that extraction equipment can capture a higher percentage of generated fumes rather than allowing dilution into the general building volume. OSHA 1910.252 requires fume control at the source; curtains help extraction equipment meet that requirement.
Weld fume curtains use FR-certified PVC or vinyl with sufficient heat resistance for the weld process temperatures in the area. Clear or translucent grades allow light transmission; opaque grades provide UV protection for adjacent areas as well as fume containment. Modular Solutions selects material grade based on your welding process and arc position.
Yes. Overhead track systems are engineered to span any bay width, with curtain panels sliding open for forklift and crane access and closing during active welding. Modular Solutions designs track geometry to match your bay dimensions and the overhead crane or hoist envelope if present.
Opaque weld fume curtain materials block UV arc radiation from passing through the curtain panel to adjacent areas. Clear and translucent grades do not provide full UV protection. For applications where both fume containment and UV shielding are required, Modular Solutions specifies opaque or shade-rated curtain materials.
