The B&Q 315mm Air Regulating Damper is an essential component for HVAC technicians and DIY enthusiasts looking to achieve precise airflow control in domestic, commercial, or industrial ducting systems. Its primary benefit lies in its ability to balance ventilation and enable effective zone management, though users should ensure their ductwork is perfectly round and measured accurately to 315mm for a secure, airtight fit.

Yes, it can be used with flexible ducting, provided the diameter is exactly 315mm and it is properly secured with clamps or tape.
While the material is durable, it is primarily intended for indoor HVAC ductwork. If used outdoors, it must be protected from weather exposure.
No, you will need to provide your own duct screws or specialized sealing tape for installation.
This damper is designed for standard air ventilation. It is not rated for high-temperature flue or industrial chemical exhaust systems.
Most models indicate the open/closed position via the handle's orientation relative to the duct axis.
Check if the screws securing the damper to the duct are over-tightened, causing the casing to deform. Loosen slightly.
This indicates an air leak at the damper junction. Apply more aluminum foil tape around the connection points.
To install, slide the damper into the 315mm duct section and secure it with appropriate duct screws or aluminum foil tape to ensure an airtight seal. Verify that the handle operates smoothly without obstruction before fully sealing the ductwork. For maintenance, periodically inspect the internal blade for dust buildup, which can be cleared with compressed air or a soft brush. Ensure that the damper handle is accessible if frequent adjustments are expected, or mark the position clearly if setting it as a permanent 'set and forget' throttle.
