Twin-Lobes Rotary Air Blowers

MONEX Twin Lobes Rotary Air Blowers are manufactured using advanced assembly and manufacturing techniques.  Our Compressors have minute clearance between the Impellers, casing and headplate to minimise "Back Slippage" of air and improve efficiency.

OPERATING PRINCIPLE :
The basic rotary blowers / compressors consist of two eight figure impellers mounted on parallel shafts.  These shafts rotate in opposite direction within an elongated Cylindrical housing.  As such each impeller lobe passes the inlet, the impeller traps a constant volume of air carries it around case and discharges it at the outlet.  This cycles repeats four times with every complete revolution of the drive shaft.  With constant speed, operation, the displaced volume is essential the same regardless of pressure, temperature or barometric pressure.

Timing gears control the relative position of the impellers to each other and maintain small but definite clearances.  This allows operation without lubrication being required inside air casing and the air delivered is 100% oil free.
