Max3 Air Brick
Max Flow Air Brick with a painted black finish.
Robust and Heavy Duty, Made by Hand with large openings to allow maximum free air flow. This is the largest free area vent with 7800mm2 in the single brick size. It is NOT suitable for fly mesh as this will reduce free area – use FLY3 instead or larger FLY6 if more free area is required combined with flymesh.
For larger orders we can supply air bricks in any RAL colour, professionally primed with 3 part epoxy + 2 part gloss or matt top coat at an additional cost – please email item number, quantity and RAL number for a proforma cost for this.
This imperial air brick can be used with duct tape to use with the metric plastic Rytons ducting for periscope and cavity wall sleeves – these are available seperately on this website.

Cast Iron Air Bricks
- Air Brick Product Guide

Cast iron air bricks are used either externally or internally, built into walls (either brick or stone) to fit flush with the wall surface and secured in place with mortar or plaster.
9" x 3" (225 x 75mm) air bricks are a very popular size as it is the standard size of an old fashioned British house brick. If air flow is important, again the max flow, as the name suggests is a clear winner.
The 9x6 air bricks are twice the size of a standard house brick, therefore allowing a greater free air flow. The 9x9 and 12x9 air bricks are also available to supply larger air flows.
