    How are folks finding Brookvent for product support?

    I've got an aircycle 1.2 with a failed supply fan.

    Brookvent will not allow the fan manufacturer to supply anybody except Brookvent (it's a custom housing/fan) and Brookvent are refused to supply spares "because not replaceable in the design of the MVHR" (kinda true but easily solved with a stanley knife).

    I get the silent treatment if asking to buy a fan for an aircycle 1.3 (which I can swap over the fan/bracket on to make it fit the aircycle 1.2)

    This leaves me with a scrap MVHR unit.

    Has anybody else had similar problems with service / spare parts?

    Does anybody have an aircycle 1.3 and would you be willing to ask if a spare supply fan is available on my behalf? (i.e. to check if this is a general "we do not provide spares" policy or they really don't want me specifically to repair this aircycle 1.2)

    That's pretty horrendous - After the warranty runs out is their only option is scrap?

    All there is to break in a MVHR is two fans and a PCB and there's loads of space - really are no excuse for designing an 'eco' product with no repair strategy.

    I was looking at their units to replace ours when we upgrade but I think they have just ruled themselves out.

    Would be interested to hear from GBF which companies are ok at supplying spares.

    Have you actually taken the fan out to see if there is an OEM part number on it? Making a custom housing for Brookvent is one thing but theres a lot of work in designing, developing, testing and manufacturing a bespoke fan. If the housing/fan is sold as a complete unit Id be surprised if it wasnt a standard fan tucked inside, especially if its a sealed unit needing Stanley knife to get into.
    I thought the UK had regulations about the supply of spare parts for a period of time after a product was last made. Might be worth asking trading standards if this is the case.

    +1 for taking it apart and looking for the generic fan part number. Whats to loose?

    Brookvent are offering a 10 year guarantee on their website, so I presume that your fan is older than that. In which case, as they're not being cooperative, I'd also try to find a generic fan. Though maybe their reluctance to help is because the fan is no longer made, in view of the timescale?

    I purchased the unit used on eBay from a chap doing a bungalow > two storey home conversion. Evidently I've found the genuine reason for sale...or he was clueless about it having failed.

    The Aircycle v1.2 is still being sold by Brookvent. It is impossible to remove the heat exchanger (for cleaning) or the fans (for cleaning / replacement) without a stanley knife. (the case is a bonded-together polystyrene affair - split the case and the fan unscrews) It's long since been in bits... ;-)

    The fans are still being made by the OEM (Torin-Sifan) but they're not willing to supply:

    Our part code 177086 (model type: MIB133-059 EC) is a bespoke customer product that is uniquely supplied to Brookvent (in Belfast). These fan units are made in volume specifically for Brookvent so are not stocked by us for general sales I’m afraid.

    Brookvent said "no" to supplying a fan for an Aircycle v1.2 and failed to respond when I asked to buy (what will be an identical) fan for an Aircycle v1.3. Their reluctance to help will not be due to "this fan is no longer made" and is either "naff off" or "we don't condone repairing this item" I suspect.

    The 10 year warranty is interesting though...I wonder how old this unit is and whether the original owner can request a replacement...

    Hmmm...installed for two years says the ad:


    I wager the resale and stanley knifing the thing open voids the warranty. Perhaps not.

    I've just got costs for a replacement fan for our unit - manufacturer does hold spares and a single fan is £233.

    Common to change them both when going through the disruption.

    Makes a new unit with a 5 year warranty look more attractive!

    A Brookvent model or a different brand? If Brookvent how did you get them? £233 is steep though!

    That was Nuaire.

    Looking in ebay vent axia are similar (circa £220):

    Looks like a combination of a relatively expensive part and a big spares mark up.

    Interestingly there is an aircycle 1.2 on there for £775 as well - I'd have considered it if I didn't know they were unrepairable:
    Ah, ok.

    I think given their approach to aftersales support I'd be inclined to write off Brookvent as a vendor whether the unit was notionally serviceable or not.

    Unit was new in 2017. Less than four years old at the point of failure. Anybody wanting an extract-only Aircycle v1.2 as a glorified trickle/boost extractor? ;-)

    It might be beneficial for consumers if you shared a link to this thread with Brookvent
    I left Brookvent a Google review this morning:

    "Beware of poor aftersales support.

    Brookvent Aircycle MVHR system. New in 2017. Supply fan failed in 2021. Brookvent claimed that "units cannot be repaired" and refuse to supply spare parts for Aircycle v.2 or Aircycle v1.3 and are no longer responding to my emails.

    I'd suggest buying MVHR systems from manufacturers who will provide spares in the event parts fail; rather than expecting you to buy an entire new unit."

    Within the hour they decided to respond to my email after all; re-iterating that their AC 1.2 MVHR unit cannot be repaired and that they will not provide spares.

    They did offer...a discount on a replacement unit...if I was will to accept a refurb...and was happy with a 1yr parts and labour warranty. (£660 rather than £750)

    I've thanked them for responding and said that given the price (that's not a no brainer price by any means) and the apparent quality (if expecting to charge for labour in order to obtain parts after 1 year it's effectively a 1 year warranty) I think the right approach is to chalk up purchasing a Brookvent product as a mistake and look for something with a warranty that indicates a 10+ year design life.

    Caveat emptor.

    It's a while before we have to finalise ducts so I'll flog the remains on eBay as spares that might be useful to somebody else with a Brookvent product and keep eyes peeled for a unit from a different manufacturer.
