Description

Extremely robust Blast Gates to automatically balance the air flow and save money & energy. 

Nordfab QF SD Automatic Blast Gates are operated by compressed air cylinders, controlled by electrically connected solenoid. 

These Blast Gates are used as energy saving devices for industrial dust extraction where extraction is not always needed and where manual control needs to be eliminated. By connecting this Blast Gate to the power supply of any industrial machine, users can save energy and money by only exhausting air during machinery operation. If the machine is off, the gate stays closed, resulting in: 

  • Increased suction at all other points in the system 
  • Lower energy requirements for the fan 
  • Less heated or cooled air exhausted out of the work area 

This Blast Gate is built for years of continuous use in the most demanding conditions. A heavy duty cast aluminum body is encased in protective galvanized sheeting to safely shield fingers from moving parts. Efforts to test the gate “to failure” were abandoned after tens of thousands of cycles. 

The long life and safety features of the SD Auto Gate are unmatched within its price range. 

They are available in 3" - 24" diameters with QF rolled ends for easy connection to QF ductwork. The Reed Switch assembly is available as a spare part.

BISCO can assist customers in designing a blast-gate system, taking into account flow dynamics that will be affected by blast gates. While blast gates can be used effectively, they can also destroy the flow if not properly placed. Contact us for assistance.
