RJL TC Long Venturi Nozzles
Tungsten Carbide Long Venturi Nozzle with Rubber Jacket
The RJL range comprises of Tungsten Carbide lined long venturi nozzles with a Rubber Jacket. Tungsten Carbide is the liner material of choice for the majority of contractors due to long life and impact resistance – the Rubber Jacket provides impact resistance for tough environments. Long venturi nozzles are used in standard applications in which the blaster operates at a distance of more than 30 cm (or 12”) from the surface.

Product description
The RJL series are available with a 32 mm (1¼”) inlet and a large thread, with an orifice range from 4,8 mm to 19 mm.
Airblast high velocity venturi style nozzles have been designed to maximize blast cleaning rates and provide uniform abrasive distribution. The venturi design accelerates the air / abrasive mix as it exits the nozzle providing additional momentum – this can increase productivity and reduce abrasive consumption by up to 40% when compared with straight bore nozzles.
Airblast offers a full selection of nozzles with various orifice sizes, nozzle lengths, insert and liner materials. Contact Airblast to discuss which nozzle is most suitable for your specific application.

Note: Best performance is obtained when sizes of nozzle, blast machine piping, blast hose and air hose are properly matched.
- m³/min and CFM range is based on blasting at 7 bar (100 psi) for the life of the
- Blast machine capacity should allow 20 to 30 minutes of blasting.
- Hose ID should be three to four times the size of the nozzle
