The AC Infinity Wall-Mount Duct Grille Vent, 100 mm is a louvred face plate that finishes a duct termination. It covers the cut edge of the opening, keeps leaves, debris and larger pests out of the duct, and leaves a tidy face instead of a raw hole ringed with tape. Made from white powder-coated steel.
Steel suits exposed positions — an external wall, a subfloor elevation, a workshop — because it takes knocks, UV and weather without going brittle.

FAQ
Will it keep insects and vermin out?
It stops leaves, debris, birds and rodents. For fine insect exclusion, fit mesh behind the grille rather than over the front, so the louvres stay clear and you are not choking airflow at the face.
Do I need a damper as well?
If the fan cycles, yes — a fixed grille does not close. Add a backdraft damper in the duct behind it. If the fan runs continuously, its own airflow keeps backdraught out and the grille alone is fine.
Steel or PVC?
Steel outdoors and anywhere it might get knocked. PVC indoors, in permanently damp spots, or where weight matters — it will never rust, but it is the wrong choice for a sun-exposed external wall.
Can I paint it?
It comes finished in white. To match a wall colour, clean and key the surface and use a paint suited to powder-coated steel. Keep paint off the louvre edges.
What sizes do you stock?
Steel in 100, 150 and 200 mm; PVC in 100 mm. Match the grille to the duct, not to the fan — reducing at the termination costs airflow exactly where you least want to lose it.
Is this genuine AC Infinity stock with an Australian warranty?
Yes. Quick Bloom Lights is the official Australian importer and distributor for AC Infinity. Stock is held in Sydney, orders ship domestically, and the two-year warranty is handled here rather than through an overseas seller.
