INW_Double stage ring blowers / vacuum pumps
Characteristic:
- wide application
- oil free operation
- quiet and low vibration
- low weight
- wide range of types and performance
- easy installation and dismantlement
- minimum moving parts
- simple maintenance
Applications:
- aeration of waste water systems or pond aeration, aquaculture
- agitation (aeration) of the solutions by the galvanic technology
- vacuum cleaning systems – industry cleaners, filters cleaning
- baths - underwater massage, bubble bath, bubble pilar
- drying process, air knifes
- pneumatic conveying system: flour, wheat, powders, synthetic fiber, capsule, etc.
- handling by the suction curve, leafing and sucking by the vacuum, thermograsp packing
- textile industry - vacuum cleaning of production waste
- printing technologies – holding the leaves by sucking
- dental technology - suction device
Principle:
Gas is taken into the device via the suction branch with built-in silencer (1). In the side channel (2) the rotor (3) transfers its speed and gas via centrifugal force is pushed toward the compression chamber. This way, along the spiralroute, gas is repeatedly pressed up to the discharge branch (4), from which it is released. With multi-stage blowers, gas flows through multiple compressor chambers placed behind one another, achieving greater pressure differences.

INW HP_high pressure blowers / exhausters can be applied as vacuum pump and compressor in continuous operation over the total stated performance curve range. The motors are available as standard for the input voltage range of 50 and 60 Hz and for protection category IP 54 (protection against dust and splashing water).
Motors are designed according to the DIN EN 60 034/ IEC 34-1 and temperature class F. For the three phase machines the tolerance +/- 10% for fixed voltage and for +/- 5% voltage range. The single phase machines are designed with a +/- 5% tolerance. If only 90% of the maximum allowed pressure will be used for continuous operating then the allowed voltage range add to +/- 10%. The frequency tolerance is maximum +/- 2%.
