Dampers

Our range of smoke control dampers are suitable for installing into low to medium velocity ductwork to perform as a volume control damper.

In the event of a fire, the built in thermal fuse will trip and cut off the electrical supply to the motor, causing the damper to close.

Our range of intumescent fire blocks are designed to stop the spread of fire through doors, ductwork and walls.

Our high velocity fire dampers are designed to stop the spread of fire through ductwork, walls, floors and ceilings.

This fire damper is suitable for medium to high velocity systems as the blades are held out of the airstream.

The fire damper is suitable for low-medium velocity systems as the blades remain partially within the airstream.

Our range of fire dampers are designed to stop the spread of fire through ductwork, walls, floors and ceilings.

For low pressure relief application, typically 5-75 pa. Used for room to room pressure control or a basic non-return valve.

For low pressure relief application, typically 10-50 pa, or as a non-return valve. Used where air velocities of up to 10 m/s may occur.

This damper gives a low air leakage rate of below 5m³/hr/m² and an insulation value of 1.8 watts/m²/°c. The linkage is enclosed.

The blades are extruded aluminium airfoil section with pvc seals and stainless steel side seals.

For control and balancing of supply and extract air systems where high pressures and velocities may be experienced.

The angles of the blades are adjusted via the robust, hand operated, lockable quadrant or with an optional extended spindle suitable for motorisation.
