Brackett air filter elements

What is the P/N? Brackett make many filters. In the TB20 for example you buy the foan insert from Brackett, for about £10.

Hi, I assume it should be for Extra 400. Do you have Extra part number of any brackett number for your filter? Or do you have ipc (part catalog for your aircraft)? I just did basic search and did not find Extra aircraft in any spec for air filters :-(

Thry Adams in the UK, if that fails , then Spruce in the US.

Two other popular UK sources are Saywell and LAS Aerospace.

Adams closed my account some years ago, saying they sell only to “trade” which in the case of an owner they defined as having 2 or more planes! This had all the signs of having had complaints from maintenance shops. I believe they have since reversed that but I haven’t used them since

Thanks guys. It is indeed an Extra 400 and I do not know the P/N. Will need to dig into the AMM and/or the equipment list.
I also heard in the meantime from the shop that they managed to order them finally. Will ask them where from…

From here

an air filter costs 200 bucks but is not replaced on every annual

@UdoR, isn’t a Brackett air filter available and approved? Link

Brackett filter elements are just a small piece of foam so in spite of being vastly overpriced for what they are, they are still inexpensive.

While the cost is lower, the airflow pressure loss through them is higher than paper filters, lowering available WOT MP on NA aircraft by around 0.5"Hg .
For turbocharged engines, the MP-effect will be nil below critical altitude but higher than NA higher up.

On my engine its apparently about 0.125 inches of mercury, not enough to be a concern to me. Obviously it varies with the size of the filter in relation to the size of the engine, and the ratio varies.
