⚡ At a Glance
- • Airflow: Maintains ventilation while preventing reverse airflow through an in-line shutter
- • Best for: Domestic bathrooms and kitchens using 100mm extractor ducting
- • Not ideal for: Standalone high-performance extraction where powered airflow is required
A PVC in-line back draught shutter designed for 100mm extractor ducts. Foam-damped vanes and a spring-and-flap arrangement reduce draughts and operational noise.
Keeps cold draughts out, with in-line back draught shutter
Two flaps close against a spring mechanism when airflow stops, creating a physical barrier to reverse flow. The in-line arrangement fits into the duct run so airflow opens the flaps during extraction and they close when the fan is idle.
Reduced ingress of cold external air improves comfort in bathrooms and kitchens. User feedback confirms effectiveness at cutting unpleasant draughts.
Quieter ventilation, with foam-damped vanes
Vanes lined or damped with foam absorb vibration and break up turbulent airflow that normally causes noise. The damping reduces rattles from flap movement during normal operation.
Noise from extractor runs becomes less intrusive, making early-morning or late-night ventilation more tolerable. Several users report noticeably quieter performance compared with undamped vents.
Simple, low-maintenance fit, with PVC construction and spring mechanism
PVC resists moisture and is lightweight, while the single-spring and two-flap design keeps moving parts to a minimum. The compact in-line format slots into standard ducting without complex fixings.
Installation and upkeep demand little time or specialist tools, so the shutter is a practical DIY upgrade for typical homes. Long-term maintenance should be minimal compared with more complex units.
