Pressure Relief Damper - Fire Rated

DESCRIPTION:

• The frame and blades are made of high-quality galvanised sheets.
• Air-operated damper blades are fixed to the frame using galvanised metal bushes.
• The blades open fully or at any angle depending on the air velocity and pressure.
• The blades close quietly when the airflow stops.
• Designed to maintain a constant pressure level inside pressurised rooms by relieving excess air when it exceeds the desired limit.
• Available in square and rectangular sizes.
• The frame has an 80 mm flange for wall mounting.
• Flanges on both sides can be provided as an option for duct mounting.
• Dampers are factory-tested for the required pressure to be maintained in the duct or room.
• The pressure relief damper can be manufactured in stainless steel as an option.
• Powder-coated finishes are available as an option in required RAL colours.
