ABOUT THIS EQUIPMENT
A bio-seal or airtight damper (low-leakage damper) is a shut-off valve for ventilation ducts where air tightness is critical. In the closed position the blade presses against corrosion-resistant seals so effectively that the valve achieves zero leakage at the specified pressure difference, stopping gases, microorganisms and other contaminants from moving through the duct. The actuator and seals are tested for reliable, fast closing in an emergency. The drive has a simple operation with clear position indication, and the seals can be replaced without specialist work, keeping downtime low. Dampers are built in materials that withstand the chemicals and disinfectants used in containment areas.
SCOPE TO CONFIRM
Damper supplied as a fixed configuration by duct size, pressure class, leakage class and drive type, confirmed before quotation.
Quoted with the damper body, seal set and drive; position switches and actuators are listed when required.
Duct installation, sealing on site and functional testing stay with the buyer or the buyer's contractor.
PACKING & DELIVERY
Include your destination, delivery port and packing requirements in the enquiry. Packed dimensions, weight, shipping scope and lead time are confirmed for the quoted configuration.
Spare parts are listed with each quoted configuration.
