CORMAK OS-4000M is a mobile welding fume extractor designed for effective capture of fumes, dust and exhaust gases directly at the source. The unit combines a powerful turbine with efficient filtration, improving visibility in the welding area, workplace cleanliness and helping to maintain occupational health and safety standards in the production hall.
CORMAK OS-4000M is an industrial mobile welding fume extractor designed for effective removal of welding fumes, dust and fine contaminants generated during welding and related work. The unit operates locally – at the workstation, allowing contaminants to be captured before they spread throughout the production hall. This significantly improves working comfort and visibility in the welding area and helps maintain occupational health and safety standards.
High extraction capacity – effective extraction of fumes and dust near the welding arc.
Large-surface cartridge filtration – high separation efficiency for fine particles.
Automatic pneumatic filter cleaning – stable operation without frequent service interruptions.
Dust container – quick and convenient emptying without mess.
Mobile construction – easy movement between workstations (workshop/production).
Simple operation – clear controls and quick access to consumable components.
The OS-4000M uses a multi-stage filtration system based on cartridge filters. This enables the unit to effectively capture fine dust and welding fume particles.
In addition, the pulse cleaning system (pneumatic) dislodges dust from the filter surfaces, which:
maintains constant suction capacity,
extends filter service life,
reduces power loss during intensive operation.
Extracting contaminants directly at the source provides an immediate effect:
less smoke in the operator's breathing zone,
better visibility of the weld and more stable working conditions,
a cleaner production hall and less dust settling on machines/installations.
CORMAK OS-4000M is suitable for applications including:
MIG/MAG, TIG and MMA welding,
metalworking and servicing work in production environments,
grinding/deburring near the workstation,
light cutting/machining work where dust and fumes are generated.
The solutions used in the OS-4000M are designed for everyday operation:
quick access to the filters and dust container,
easy replacement of filter cartridges,
automatic cleaning reduces manual servicing and downtime.
