Application

ERGO/KOS-AL extraction system has been developed for capturing the welding fumes at the mobile welding stations, for welding
straight-shaped elements – of length from several metres up to several-teens metres.

The assembly can be operated by one or two extraction fans, depending on the quantity of applied ERGO extraction arms (one ERGO arm
is cooperating with one fan).

Structure

The ERGO/KOS-AL extraction system consists of subsequent assemblies:

• self-tightening suction duct – type KOS-AL (of aluminium segments of length 6,5 ft or 13,1 ft – joined together into a requested duct length),
  
• trolley – displacing along the duct,
  
• extraction arm ERGO or ERGO Flex – suspended underneath the trolley,
  
• fitting pieces and supporting elements – according to the arrangement below.

Operational use

During the welding the operator moves the ERGO extraction arm with the trolley along the duct. Th e suction hood of the arm ought to be adjusted in a distance ca. 11,8 in. from the welding point. Low movement resistances of the trolley and easy adjustment of the hood
provides perfect manoeuvring of the whole system.

Aft er the completed work at one welding post, close the shut-off damper (placed at the hood) to improve the suction volume in the second extraction arm.

Two extraction arms can be installed at one suction duct simultaneously.
