Proton Air

Comes complete with a RV5 spray gun.
The device is designed for applying polyurethane foam, but it is also capable of spraying some types of polyureas.

Features of the PROTON Air device:
Piston pumps — precise dosing of components;
Insulated heated hoses maintain the optimum temperature of the components;
The pneumatic drive is a guarantee of reliability and durability of work;
Smooth control of the supply of components;
Instantaneous shut-off of the supply of components, as on high-pressure devices;
Ergonomic and compact design;
Mobility;
Easy maintenance.
PROTON Air uses pumps similar to Graco pumps to supply components. Thanks to this, a more accurate dosing of the material is achieved. The components are taken directly from the barrels. It is enough to open the barrels, immerse the intake hoses in them and turn on the installation. Better mixing is guaranteed due to the combined spraying system, i.e. the components are mixed both due to compressed air and increased pressure of the supplied materials. The mixed components fly out of the spray gun in the form of an aerosol torch. The maximum length of hoses from the installation to the spray gun is 40 m. The main advantage of the PROTON Air installation is the use of a pneumatic drive, which increases energy efficiency and reliability.

The principle of operation of the gun: components through special nozzles at a pressure of 10 bar enter individual mixing chambers in which they are sprayed and mixed with compressed air supplied to the same chambers from the compressor. After that, each component, being in an aerosol state, is mixed with compressed air, and enters a common mixing chamber, in which two aerosol materials are already mixed together. This mechanism of operation improves the quality of mixing components and reduces consumption. When the trigger of the gun is released, the material supply is instantly blocked (as in high-pressure devices). The channels of the gun are cleaned of the remaining material with compressed air.

Recommendations on compressor characteristics:
For the operation of the device: compressed air consumption 250-300L / min, pressure 6-8atm.
For the operation of the spray gun: compressed air consumption 300-350L/min, pressure 2-4atm.
A series of Russian-made devices for spraying polyurethane foam PROTON began in 2010
G. with the development of high-pressure equipment, since this method is considered the most qualitative. PROTON Air significantly surpasses conventional low-pressure installations widely used in Russia, combining the ease of maintenance of low-pressure devices, ease of operation, feed accuracy and mixing quality of components of high-pressure installations.

During the production of work, the raw materials (components "A" and "B") must be heated — heating reduces the viscosity of the components, which improves the quality of mixing and reduces the consumption of raw materials.
PROTON Air is equipped with a performance and temperature controller, which makes it more convenient to configure the installation for a specific type of PU system.
