CORMAK OS-4000M

CORMAK OS-4000M is an industrial, mobile welding fume extractor designed for the effective removal of welding fumes, dust, and fine contaminants generated during welding and related operations. The OS4000S features a new, lower housing design. The device operates locally—at the workstation—so that contaminants are captured before they spread throughout the workshop hall. This directly improves working comfort, visibility in the welding area, and helps maintain occupational health and safety standards.

Specifications:

- Model: OS4000M
- Power supply: 400 V
- Power: 4.0 kW
- Airflow: 3,000–4,000 m³/h
- Operating pressure: 3,050–2,600 Pa
- Filtration efficiency: 99.00%
- Number of filter cartridges: 4
- Filter specification: Ø325 × 600 mm
- Filter material: polyester
- Filter cleaning method: pneumatic, pulse-jet
- Dust bin capacity: 50 l
- Noise level: ≤ 78 dB(A)
- Dimensions: 900 × 900 × 2,300 mm

Why choose the OS-4000M?

- High extraction efficiency – effective suction 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 servicing interruptions.
- Mobile construction – easy movement between workstations (workshop/production).
- Dust collection bin – quick and convenient emptying with minimal mess.
- Simple operation – clear controls and quick access to consumable components.

Efficient filtration and constant suction power

The OS-4000M utilizes a multi-stage filtration system using cartridge filters. This enables effective capture of fine welding dust and fumes.

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

- Maintains consistent extraction performance
- Extends filter lifespan
- Reduces drops in power during heavy-duty operation

Workplace comfort and safety

Extracting contaminants directly at the source provides immediate benefits:

- Less fume in the operator’s workspace
- Improved visibility of the weld and more stable working conditions
- Cleaner hall and less dust settling on machinery and installations

Applications

CORMAK OS-4000M is ideally suited for:

- MIG/MAG, TIG, MMA welding
- Metalworking and servicing in production environments
- Grinding/deburring near the workstation
- Light cutting/processing tasks where dust and fumes are generated.
