Hi this is Tom from the Ministry of Mould just a really quick video to show you a PIV up close because lots of people always ask are they noisy are they drafty will it be a pain in the ass if it's in my house will I hate it well the answer is no
so this is a video showing you a diffuser of a PIV and hopefully with the use of some cobwebs you'll be able to see that they really don't put out much air so it's not going to be drafty and it's not going to be noisy but it will get rid of condensation so let's have a look at the diffuser this is a diffuser for PIV vent axia model above that I've just noticed this has just been installed but can you see there's a cobweb there below it is barely moving hardly moving if I blow see it moving now the actual prv unit which is running it's barely doing anything there's another cobweb there just about moving this is a very low flow from a PIV this is not going to be causing a dramatic draft blowing your hat off as you go up the stairs this is a light constant trickle of air which pressurizes the home and gets rid of condensation and mould problems English (auto-generated)
