The Walinga Super Hardened SRT Blower

The Walinga Super Hardened SRT Blower is available in two sizes:
1100 cfm capacity Model 510
1800 cfm capacity Model 614

Walinga Super Hardened SRT Blowers are manufactured to exact specifications and quality control standards. The housing, end plates and impellers are precision machined.
Gears and bearings are "splash lubricated". For the Central Vac application, these blowers operate at very low rpms extending the life of the blowers.

Drop Thru Airlock

Cast iron precision machined housing for longer life.

Adjustable airlock rotor tips available in:

  • Knife Edged Carbon Steel
  • Stainless Steel
  • Composite Rubber

Electric motor drive for separate start/stop operation.


  • Super Hardened Airlock
  • Closed End Rotor Airlock

Primary Separator

Comprehensive engineering capabilities allow for the unique computer designed cyclone fitted to your specific application. Designed to provide optimum performance and to keep discharge dust to a minimum. The Separator provides effective separation of dirt and air. Combined with the separately controlled drop-thru airlock, the Separator contents can be discharged into dumpster or back into your production system. Primary Separator is available with a liner.

Secondary Cyclone

Located “up-stream” of the blower, the Secondary Cyclone is designed to remove excess dust from the air stream prior to the air getting to the blower. The Secondary Cyclone is designed to remove additional dust not caught by the primary separator. This allows for minimal dust to reach the filter canister.

(SHOWN: Optional Automated Slide Gate)

Filter Canister

The filter canister can be located in a easy to maintain location close to the ground. It keeps dust out of the blower, which protects and prolongs its life. It also ensures clean air discharge from the blower into the atmosphere.
