CORMAK OS-4000S

CORMAK OS-4000S Welding Fume Extractor

The CORMAK OS-4000S is an industrial welding fume extractor designed for effective removal of welding fumes, dust, and fine contaminants generated during welding and related operations. The OS4000S features a new, lower-profile housing. The unit operates locally at the workstation, capturing contaminants before they spread throughout the workshop or production hall. This significantly improves working comfort, visibility in the welding area, and helps maintain workplace health and safety standards.

Why Choose the OS-4000S?
High extraction performance – effective suction of fumes and dust near the welding arc.
Large-surface cartridge filtration system – highly efficient separation of fine particles.
Automatic pneumatic filter cleaning – stable operation with fewer maintenance interruptions.
Dust collection container – fast and convenient emptying without mess.
Easy operation – user-friendly controls and quick access to consumable components.
Effective Filtration and Consistent Suction Power

The OS-4000S uses a multi-stage filtration system based on cartridge filters. This allows the unit to efficiently capture fine dust and welding fume particles.

Additionally, the pneumatic pulse cleaning system shakes dust off the filter surfaces, which:

maintains constant suction efficiency,
extends filter service life,
reduces performance loss during intensive operation.
Comfort and Safety at the Workstation

Extracting contaminants directly at the source provides immediate benefits:

less smoke in the operator’s working zone,
improved weld visibility and more stable working conditions,
cleaner workshop environment and reduced dust accumulation on machines and installations.
Applications

The CORMAK OS-4000S is suitable for:

MIG/MAG, TIG, and MMA welding,
metalworking and maintenance operations in production facilities,
grinding and deburring near the workstation,
light cutting and processing operations that generate dust and fumes.
