Alpha 440 Feature of the Week: High Velocity Blower Inlet Stack

Posted by

High Velocity Vacuum Relief Inlet Stack

The Alpha 440 is engineered to have the vacuum relief valve mounted directly above the blower for maximum performance. This ensures longer belt life and aids in the prevention of the blower loading up if the waste tank filters get clogged.

Other units have the Vacuum Relief mounted on the waste tank. If the Blower Inlet Filters are not cleaned after every job, it will put strain on the belts and vacuum blower system which will cause premature belt OR blower failure.


  • Stainless Steel and High Quality Machined Aluminum Construction
  • Protects the Life of the Blower and the Belts.
  • The Large Inlet Stack is uniquely engineered to provide maximum air flow and vacuum.
  • Direct injection to the blower is essential when "lubing" the blower with our exclusive Easy Lube System. Lubricant is injected directly into the vacuum blower ensuring proper lubrication of the lobes.
  • High quality wire reinforced high temperature hose and stainless steel clamps are used to connect the vacuum blower to the waste tank.
