Special Model : AIRMISER

There are variations available in the standard production of Airmisers. These range from the tiny MICRO through the two 1/2″ BSP units to the “Monsters” 1″ BSP nozzle, produced for blasting swarf and debris from the support leg of a North Sea Oil Rig. Details of these special units on application.



The Beck Airmiser uses a series of annular nozzles instead of a single hole to create a safer, more energy efficient, lower noise alternative to open tubes and pipes.

A small volume of compressed air is AMPLIFIED UP TO 25 TIMES by utilising the Coandă effect to induce a higher flow of ambient air into the air stream.

Replacing open jets with Airmisers will give SIGNIFICANTLY REDUCED AIR CONSUMPTION & LOWER NOISE levels. In many cases, it is a simple operation to install Airmiser nozzles.

Airmises are suitable for use individually or in multiple arrays to create a much greater effect.

The multi-nozzle arrangement of the Airmiser is designed to be a much safer alternative to standard compressed air. The unique design prevents injury caused by air entering the bloodstream via a single open pipe at high pressures, safeguarding operators and reducing risk.

  • No moving parts – means the Airmiser is maintenance free
  • Low air consumption means significantly lower running costs than open holes and pipes
  • Quieter Operation (below 80 dB (A) at 1m) for an improved working environment
  • Easily mounted onto existing installations

The Beck Airmiser Jet uses the proven technology from the Ringjets to create a high velocity flow where greater performance is required for blow off and cooling applications.

The Safety Handgun uses the same technology as the Airmiser but with the convenience of an ergonomic handle making it a useful general purpose blow off tool.

The Pneumatic Airstrip is particularly suitable for drying applications in either handheld or stand mounted format

More Information

Airmiser Nozzles combine economic air usage along with noise reduction offering outputs up to 28-times compressed air input. By diffusing a single, direct compressed air jet they also have significant safety value by preventing embolism. Key uses are for cooling, blowing, drying and, by utilising high thrust, ejecting parts from press tools. The range comprises of eight models in aluminium with attachment diameters from 1/8″-1″BSP. For accurate, stable positioning the Rigiflex hose accessory is recommended.

AIRMISER nozzles have a total effective air output of up to 25 times the compressed air input and the STANDARD nozzle SA can replace the nozzle normally used on many blowguns to produce greater thrust with increased safety.

Instead of a single hole at the nozzle tip which could permit a high pressure air jet to impinge directly onto the operators’ skin, a series of annular orifices at the base of the nozzle induce an additional flow of ambient air at relatively low pressure to provide high total thrust with increased safety. The flow of air through a series of annular orifices reduces the possibility of metallic chips rebounding back towards the operator.

The high thrust relative to their size of the MINI AIRMISER Model MA and the BLOW HARD AIRMISER Model BH make them ideal for Cooling, Ejecting Parts from tooling, Drying and Blowing. They consume less air than an ordinary nozzle with reduced noise levels. With input pressure in the region of 6 bar gauge (90 PSI) typical noise levels with AIRMISER nozzles are well below 80 dBA. To obtain optimum performance with minimum air consumption install a Filter/Regulator with pressure gauge in the compressed air supply line to the AIRMISER.

When using multiple arrays of AIRMISER nozzles ensure that all the pipe-work and the Filter/Regulator is of adequate size to handle the amount of compressed air required.

Substitution of AIRMISER nozzles for open jets in addition to reducing noise will produce substantial savings in compressed air consumption, especially when multiple arrays are required.

The Model MA uses less compressed air at 4 bar (60 PSI) than a 1.6mm (1/16″) open jet but produces considerably more thrust due to entertainment of ambient air.

The performance of Model BH when compared to that of a 6mm (1/4″) open jet shows that it provides substantially more effective thrust at about one third the compressed air consumption.
