Max Flow Air Brick, available with a painted black finish or bare metal.
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 company 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 of £200+vat- please email item number, quantity and RAL number for a proforma cost for this.
Painted vents use two part epoxy black gloss top coat which is hard wearing but is just a decorative finish, like all painted cast iron products it will require repainting from time to time, especially if situated on an exposed wall. Repainting can be frequent if the grille is positioned in the sunlight, or chipped or exposed to salt air . The gloss paint will dull over time, in exposed conditions it is likely to dull to a satin sheen fairly quickly. Regardless of the paint finish the cast iron grille will last for many decades with or without painting.
This imperial air brick can be used with the METIMP3 aluminium adapter to combine with the metric plastic Rytons ducting for periscope and cavity wall sleeves – these, and the adapter are available separately on this website.
The MAX3 air brick ventilates, amongst others, the stunning Portland stone, grade 2 listed property on Tabernacle Street in London known as Lowndes House. This building now houses offices and is a well known feature being especially recognised for it’s unusual wedge shape and its beautiful dome and pinnacle.
