CORMAK OS-4000S

CORMAK OS-4000S is an industrial welding fume extractor designed for the efficient removal of welding fumes, dust, and fine contaminants generated during welding and related activities. The OS4000S features a new, lower-profile housing. The unit operates locally—directly at the workstation—therefore contaminants are captured before they can disperse throughout the hall. This significantly improves workplace comfort, visibility in the welding zone, and supports occupational health and safety standards.

Why choose the OS-4000S?

- High extraction performance – effective fume and dust capture near the welding arc.
- Large surface area cartridge filtration – highly effective separation of fine particles.
- Automatic pneumatic filter cleaning – stable operation with minimal maintenance downtime.
- Dust bin – hassle-free and quick emptying with no mess.
- Simple operation – user-friendly controls and easy access to serviceable components.

Efficient filtration and constant suction power

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

Additionally, the pulse-jet cleaning system (pneumatic) shakes dust off the filter surfaces, which:

maintains consistent extraction performance,

extends filter service life,
reduces suction losses during intensive use.

Comfort and safety at the workstation

Extracting contaminants directly at the source provides immediate benefits:

less fume in the operator’s workspace,
improved visibility of the weld seam and more stable working conditions,
a cleaner shop floor and reduced dust accumulation on machines/installations.

Applications

The CORMAK OS-4000S is ideal for:

MIG/MAG, TIG, MMA welding operations,
metalworking and maintenance tasks in production environments,
grinding/deburring close to the workstation,
light cutting/machining processes where dust and fumes are generated.
