Blast Gate Dampers

Ventilation Ducting  | Dampers & Access Doors |  Blast Gate Dampers




Blast gates are designed primarily for use in industrial exhaust systems extracting fumes, dust, wood waste, etc. They have also been used extensively in agricultural machinery, marine ventilation, stokers, furnaces and grain drying plants. Zest blast gates are easy to operate with the freely moving blade being locked into the open or closed position by means of a simple thumb screw.

Blast gates are robustly constructed with the main body being die-cast from aluminium alloy. Blades are manufactured from corrosion resistant ‘zintec’ steel. Their design provides for ease of installation in both new or existing systems and disassembly where cleaning is necessary.
