About Nozzles and accessories

The nozzle decides what an air blow gun actually does at the workpiece. Blowing force, jet shape and noise level come from the nozzle, not from the grip. The group holds 109 items, including versions and extensions with lengths from 35 to 800 mm.

What matters when choosing

• Length ranges from 35 to 800 mm. Short nozzles for work directly at the part, long tube versions to reach into machine enclosures, fixtures and deep bores.
• The nozzle type sets the jet shape. Round nozzles concentrate the air on one spot, flat nozzles spread it into a wide curtain, fine spray nozzles work with a small orifice.
• The material is nickel-plated brass or aluminium. Aluminium keeps long versions light, nickel-plated brass is the heavier choice for continuous duty.
• Nozzle and accessory are chosen together. If the blowing direction at the machine has to change, combine an extension with the nozzle instead of replacing the whole gun.

Typical applications

• Blowing off chips and coolant after machining
• Clearing blind holes, bores and threads at the assembly bench
• Drying parts after washing or pickling
• Cleaning fixtures and clamping devices between cycles
• Low noise versions at workstations where blowing runs continuously

The 109 items in this group cover nozzles in nickel-plated brass and aluminium plus the matching accessories. According to the Riegler description, the low noise versions reach a lower sound level than conventional single-hole nozzles at the same blowing force when correctly sized.
