Unique to the length of the gun supply pipe - 500 mm, provide accurate delivery of the foam as deeply in inaccessible places, without the use of additional nozzles. The advantage of a long tube feeding foam gun for and additional removable front nozzles which are often used installers, due to the possibility of accurate delivery and an economical material in inaccessible places while maintaining foam properties. correct also stored cellularity density cured foam, the foam expansion process is predictable and controlled, both primary and secondary. Polyurethane foam, adhesive foam served directly from the gun and the same foam supplied from a gun extending through the additional nozzle has a totally different structure. By using additional feed nozzles becomes less uniform, and more friable foam. Initial expansion of air handled and not typical composition used foam. In addition, the foam flow is greater. The foam is fed through the nozzle extender has unpredictable secondary extension and loose structure of solidified material. Gun PT-0650 foam solves all the above problems. 500 mm long nozzle delivers foam deeper than other spray guns without changing the structure of the foam, and can accurately adjust the flow of the material, which ensures the exact dosage and saves consumption of material. The needle and tube are made of stainless steel and do not corrode. Reliable shut-off valve does not make you worry about the output of the foam from the gun when changing the bulb, and provides tightness during storage pistol. Brass needle tip ensures leakproofness even during very long-term operation pistol. Metal trigger is absolutely not subject to wear. Cast aluminum housing is lightweight and reliable. Does not tire the hand and does not give chances to the leakage of foam is resistant to mechanical damage. Four additional tip complete provide a supply of foam in remote places, and a specific application gun. Guarantee trouble-free operation for as long as possible in any range of ambient temperatures and in high humidity conditions, when performing assembly work of any complexity.
