WIWA PU GUN 4040 – the 2K gun for PUR foams and polyurea
With the PU GUN 4040, WIWA offers its own spray gun for processing PUR foams and polyurethanes/polyurea. The air-operated gun works on the counter-flow principle: the POLY and ISO components only meet in the mixing chamber, at up to 250 bar, immediately before the material leaves the tip. Simply exchanging the mixing chamber adapts the output to any requirement. Low weight, an optimised grip design and the variable arrangement of the fluid connections allow fatigue-free work even on large surfaces.
Your benefits
- Easy output adjustment: just exchange the mixing chamber
- Fatigue-free use: low weight, optimised grip, variably arranged hose connections
- Easy conversion: from hand to automatic gun and back with an adapter
- Flexible: for round and flat spray tips
