I was given from my son a jet ceiling air filter with remote control for Cristmas. I have removed the two filters from it at the the very front on pleated and another charcoal filter also pleated inside is basically a nice squirrrel fan with a box, and a few filters interchangeable type .Also and a small brain for the remote control speed ,on off etc,.Noiw I have been tinkerring with the idea of making a copy of this as I have two identical squirrel fans from a central heating type industrial boiler.
I copied it adding the second fan and bought the said filters and some filter material ( wow that stuff is expensive) lol, anyway it works great I put an aluminium sheet at the front with some holes drilled about an inch each and about ten per fan . These holes correspond with the fronts of the fans where the air can escape and It is blowing the air through this like billey-oh from the rear,and as the box is otherwise well sealed .However when it all came together there is as said a great draft from the rear but almost unoticeable drawing of air from the front.
Is this correct ? I know they are advertised as air filters not extractors.The jet is about the same or little better.
Now common sense, added to a dab of physics , tells me if the box is sealed apart from front and rear and the air is blowing great from the rear outlet then it has to be coming through the front and subsequentally through the filters situated at the front ,doesn’t it?
It just seems very weak although the double fans are very powerful and strong as said.I am just not used to them .Now my question is do you reckon everything is as it should be? Please help me as Obviously I don’t want to fit it to the ceiling as I am not rightly fit and healthy for the job and will need help with this heavy task . if it is not working properly .So any of you with such a ceiling fan or know of them please help me out with advice.Incidently thelt was a great help to me with the dust collector seperator he is a very clever man and super nice thanks buddy if you read this THELT Alistair
