SCL Brower

Lateral channel blower-exhauster

OPERATING PRINCIPLE

The lateral channel blower-exhausters (SCL) have been developed on the theory of the regenerative flow.

Due to their unique principle of operation and design, there is no contact between rotating and stationary parts.

The main advantages are the following:

  • no wear parts
  • no lubrication required
  • minimum maintenance
  • silent operation
  • smooth air flow

DESIGN

The standard design, direct drive, with housing and impeller made of aluminium alloy, and dynamically balanced impellers fitted directly on the motor shaft.

The electric motors are 2-poles, single and three phase, rated for continuous service. Insulating class ‘F” – Tropicalized, with IP54 or IP55 protection and built to IEC standards. Standard voltage is V230/400-50Hz -V265/460-60Hz up to 4 kW and V400/690- 50Hz – V440/760-60Hz from 5,5 kW and above.

Different voltages are available on request. Separate V-belt drive blowers are also available which may be coupled to different motors (explosion-proof, hydraulic and gas engine) where a speed of 4500 rpm can be reached with subsequent higher performances.

We can also supply special blowers to handle high pressure and high temperature gase, or specialty/corrosive composition, by incorporating specific materials including special surface treatments and use of different seal types.

Particularly a dedicated range was developed:

  • manufacturing material is the aluminium alloy
  • impregnation of all parts in contact with the gas
  • sealing of union parts
  • overhang support with double mechanical seal on the shaft

PERFORMANCES

The data provided refers to the handling of gas having inlet temperature of 15°C, normal density of 1,23 kg/m3 and absolute pressure of 1013 mbar.

This data can change in accordance with the following factors:

  • Any variation in absolute outlet pressure of 1013 mbar (suction)
  • Any variation in absolute inlet pressure of 1013 mbar (discharge)
  • Operation using inlet and outlet simultaneously (back pressure at discharge port and suction at the inlet port)
  • Handling of fluid having different den­sity from 1.23 kg/m3 .
  • Variation in speed of rotation in relation to the basic one at 50 Hz (2900 rpm) and 60 Hz (3500 rpm)
