ASA 4 Series

The ASA 4 Series of extraction arm is for welding, glue, grinding fumes in particular and for operators requiring manoeuvrability, comfort and efficiency. The hose and ALU duct are mounted on the outside of the carrying arm, in order to let the air flow pass more freely resulting in the lowest possible pressure drop. This extraction arm series has 3 stables and 2 turning points and is movable in all positions up to 180°.  The ASA 4 is a duct arm with external carrying arm and aluminum duct with hose.

The ASA 4 Series is available in lengths of 2,0m, 3,0m and 4,0m. The arm can be extended up to 8m by means of extension arms.

The arm is mainly constructed in ALU parts in order to keep the total weight down, which results in smooth operation. ASA 4 has a lower pressure drop than the ASA 3. Use and construction is very similar to the ASA 3.
