The concept

With the new development of the WIWA PU GUN 4040, 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.
