The KUA ATEX is a flexible extraction arm solution for use in explosive environments
KUA is the extraction arm of choice and comes in various models. It is a flexible extraction arm for fume, gases and oil mist contaminants. Unique to the KUA is the combination of inner and outer arms of smooth aluminium tubing connected by our unique middle joint. The external easy-to-adjust elbow joint and the spring-assisted joint supported in double ball bearing make manoeuvring this arm a simple, one-movement operation. Position the arm exactly where you need it, when you need it.
Type ATEX (for use in explosive environments zone 1 and 21; marking Ex II 2G 2D) has a hose made of polyethylene with copper coated spring steel wire and is for use in explosive environments. Only for hanging mounting.
Recommended for
