Side Channel Blowers

CR Elec blowers are complete units ready for immediate installation either as a vacuum or as a compressor. The unit can be mounted in any position, horizontally or vertically.

Our comprehensive range of side channel blowers are fitted with single or three phase motors and include the option of:

  • A Single stage vs Double stage design

  • 50Hz Operation

  • Direct, V-belt or Coupling Drive

  • 220V/380V/525V

 

Advantages of our blowers include:

  • Long life bearings
  • Low noise levels
  • Oil free operation
  • High efficiency TEFC (IP54) motors
  • Pressure, Vacuum, Suction and Aeration applications

Suitable for a diverse field of applications such as pneumatic conveying, bakery materials handling, dental aspiration, spa bath, socks knitting machine, plastic granule conveying, sewage treatment, compost, furnace air supply, metal treatment baths, bottling plants, to name a few.

Sirocco/EcoAir blower includes an impeller and a side channel formed with a semi-circular side wall and having an inlet and outlet. As the impeller rotates, the gas between the impeller blades is radically and circumferentially accelerated and pushed into the side channel.

Here it is compressed and forced back towards the impeller blades where it is radically and circumferentially accelerated. It is thus transported along a spiral path through the impeller and side channel, until it reaches the point where the side channel is connected to the discharge flange. Here the gas is discharged.

Sirocco/EcoAir blowers also have long life bearing at each end of the shaft outside the pumping chamber. The advantages are:

  • Higher pressure ratios achievable.
  • Cooler bearing temperature.
  • Longer grease life.
  • Easier access for maintenance.

Under serious QC control and with over many years' experience, the parts used in Sirocco/EcoAir blower are of top quality and all motors are TEFC(IP54) and insulation class F is for 2 Horse power and below, and insulation class H is for 3 Horse power and above. The pump is separated from the motor maintenance-free shaft seal.

The use of direct-driving Sirocco/EcoAir low-noise motors and integral silencers ensure a low noise level.

The impeller rotates with absolutely no contact between it and the housing. This means no lubrication is required, guaranteeing 100% oil-free operation.
