The professional dual-component gun for processing PUR foam and polyurea
The concept 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.
The case The scope of delivery also includes a case manufactured from sturdy materials, which contains a comprehensive range of all tools and lubricants required for gun disassembly and maintenance in addition to the gun itself. Other accessories such as nozzles, mixing chambers, filters and connection adapters can also be stored and transported in the robust, generously dimensioned case.
