17 (1)It consists of a pressure vessel that is fed through a shut-off valve. During operation, the vessel is pressurized and the material, along with the long air, is dragged through the hose and expelled through the nozzle at high speed.

It is a more energy efficient process than with suction guns. It can be used in cabinets (BP series) but is most commonly used in cabins or open blasting.

The vessels are manufactured with capacities between 40 and 4500 liters, with outputs for one or more operators, direct or remote controls, with discontinuous or continuous operation (double chamber), finally, with several operational options and the hoses can be longer than 30m, allowing to operate long distance of the equipment.

The diameter of the nozzle defines the compressed air consumption indicated on the side. Its progressive wear increases consumption and it is recommended to provide air capacity up to 20% higher than indicated.

Rated power absorbed from a compressed air network for new nozzles. For a compressor directly connected to the pressure vessel, capacities of 15 to 20% higher are recommended.

Comparative reference to the production of the 1/8 ”diameter pressure nozzle.
