.jfif)
Airblast 'Venturi' jet nozzles are specially designed to provide the maximum level of air blast cleaning with an even distribution of the abrasive over a long service life.
All nozzles are united by industry-standard threads, making it possible to quickly remove the nozzle holder and avoid clogging.
Calculation of the required amount of compressed air (m 3 / minute)
Nozzle diameter, mm | Air consumption at 8.0 bar | Plus helmet | Plus 50% reserve | Minimum required air volume |
6.5 | 2.3 | 0.5 | 1.4 | 4.2 |
8.0 | 3.9 | 0.5 | 2.2 | 6.6 |
9.5 | 5.5 | 0.5 | 3.0 | 9.0 |
11.0 | 7.2 | 0.5 | 3.9 | 11.6 |
12.5 | 9.6 | 0.5 | 5.0 | 16.1 |
The main materials for the production of Airblast jet nozzles are tungsten carbide, silicon carbide, boron carbide, silicon nitride.
Approximate nozzle life in hours *
Nozzle material | Fraction | Sand | Aluminum oxide |

Silicon carbide | 600-1000 h | 400-600 h | 50-100 h |
Boron carbide | 1500-2500 h | 750-1500 h | 200-1000 h |
Nozzle holders and connections
AIRBLAST offers a very large selection of couplings to fit all jet hose sizes. AIRBLAST nozzle holders are available in nylon and aluminum. "AIRBLAST" quick couplings are available in nylon, aluminum, cast iron and brass. All types are equipped with wear-resistant, replaceable rubber gaskets.
Hoses
AIRBLAST hoses provide maximum strength and durability under intensive use. Hoses can be completed with nail connections.
Jet hoses
In accordance with the most demanding standards, the jet hose is equipped with a high-strength textile, spirally wrapped around the hose between rubber gaskets. This creates a robust, static and knot-free hose that fully complies with all international standards. All available hoses, regardless of diameter (1/2 ", 1", 1 1/4 ", 1 1/2", 2 "), meet these high standards.
Air hoses
The air hose supplying filtered air to the protective helmet meets the requirements of the SES.
Vacuum extraction hoses
The hose for collecting abrasives is equipped with a reinforced wire with a polyurethane, rubber or PVC sheath.
Pressure gauge with a needle
During blast cleaning, the pressure at the nozzle outlet can be significantly less than that at the compressor outlet - this can negatively affect productivity. The presence of a portable pressure gauge allows you to monitor the pressure and timely identify a leak or blockage in the hose.
Abrasive feed control valves
AIRBLAST abrasive feed control valves are distinguished by their reliability and durability under intensive use. The convenient design allows you to quickly and easily replace worn parts: in the valve type SGV valve, designed to work with steel shot, there is a rubber bushing, and in GVA and FSV valves, rubber bushings and gate valves, respectively.
"Double Venturi" nozzles
"Double Venturi" jet nozzle - due to the consistent reapplication of the "Venturi" principle and the manufacturing geometry, it is possible to increase the jet of the cleaning spot by 35% with the same volume of air flow.
