CORMAK OS-4002 is an industrial welding fume extractor designed for effective removal of welding fumes, dust and fine contaminants generated during welding and related work. The OS4002 has a new, lower housing. The device operates locally – at the workstation, so contaminants are captured before they spread throughout the hall. This genuinely improves working comfort, visibility in the welding area and helps maintain health and safety standards.
Why OS-4000S?
-
High extraction capacity – effective suction of fumes and dust near the welding arc.
-
Large-surface cartridge filtration – high efficiency in separating fine particles.
-
Automatic, pneumatic filter cleaning – stable operation without frequent servicing breaks.
-
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.
Effective filtration and constant suction power
OS-4000S uses a multi-stage filtration system based on cartridge inserts. As a result, the device effectively captures fine dust and welding fume particles.
In addition, the pulse cleaning system (pneumatic) “shakes off” dust from the filter surfaces, which:
-
maintains constant suction capacity,
-
extends filter service life,
-
reduces power drops during intensive operation.
Comfort and safety at the workstation
Extracting contaminants directly at the source gives an immediate effect:
-
less smoke in the operator’s breathing zone,
-
better weld visibility and more stable working conditions,
-
a cleaner hall and less dust settling on machines/installations.
Applications
CORMAK OS-400OS is suitable, among others, for:
-
MIG/MAG, TIG and MMA welding,
-
metalworking and servicing work in production,
-
grinding/deburring near the workstation,
-
light cutting/machining work where dust and fumes are generated.
Operation and servicing
The solutions used in the OS-4000S are focused on everyday operation:
-
quick access to the filters and dust container,
-
easy replacement of filter inserts,
-
automatic cleaning reduces manual handling and downtime.
