PU GUN 4040
The professional dual-component gun for processing PUR foam and polyurea
With the new development of the WIWA PU GUN 4040 automatic gun, we are expanding our wide range of innovative PU application technologies with our own spray gun. The concept for this pneumatically driven gun is based on the counter-current principle. The ISO and poly components only come into contact in the mixing chamber at a pressure of over 250 bar immediately before material is discharged through the nozzle. The capacity of the gun can be adapted quickly and easily to the corresponding requirements by simply exchanging the mixing chamber.
The automatic gun
In addition to hand-held use, the spray gun can also be used in an automatic coating system with the optional adapter. To do so, the handle is simply replaced with an adapter. The control air connection is made via the bushings on the rear of the adapter.
