Adjustable Round Disc Air Diffuser Fresh Air Ceiling Vent

Adjustable Round Disc Air Diffuser — Ceiling Valve with Integrated Volume Damper

A round pop disc diffuser with an integrated air volume damper. Turning the centre disc opens or closes the airway, giving stepless regulation right at the terminal. The flat panel sits almost flush with the ceiling, which keeps the visible face minimal in finished interiors. It is the usual choice for supply and extract points that need balancing after commissioning.

Key Features

• Integrated volume damper — balance each terminal without extra duct dampers
• Pop disc design — the centre disc lifts to open, giving stepless regulation
• Flat minimal panel — near-flush ceiling appearance in finished rooms
• Easy ceiling installation — spring-buckle or screw fixing depending on model
• ABS construction — wipe-clean, corrosion-free surface

FAQ

A: Yes, the disc assembly can be removed and wiped without dismantling the duct.

Q: Are other colours available?
A: Standard finish is white. Custom colours can be quoted for project orders.
