laminar flow hood
« on: August 26, 2009, 11:52:10 AM »

Im building a laminar flow hood.I am wondering if i can make, that the blower is blowing directly in the hepa filter!
In my case, the blower would be in the back instead on the top!

cugak, i guess i'm lazy. i went to home depot and picked up a honeywell air purifier, model 16200.. its a 99% hepa filter, electronic ionizer comb... i think i payed about 70 bucks, it works great..  -_- i turn it on 1/2 hour before i work and do all my work in front of it.. no problem yet..  :mellow:

I checked out that model online and you can get it for $40. Here's a link: http://www.drugstore.com/qxp84989_335997_sespider/honeywell_enviracaire/hepa_air_purifier_model_16200.htm

And at this purifier the fan is at the back side so it is blowing directly into hepa filter and out in the working area?(its not on the top so can it be that normal exhaus propeler one?)
And do you know what kind of fan it is? Is it in-line centrifugal fan, squirrel cage blower , or is it that normal exhaust propeler one ...?

cugak, i'm not sure what type of fan it is. the fan is sealed inside the unit. but it pulls the air in from the top and blows out the side.. there are 3 filters, the 1st is a washable pre-filter, 2nd is a carbon filter and 3rd is the 99% hepa filter..then before the air comes out of the unit.. the clean air passes through an ionizer.
i have been using it for about a year with no problems.. i clean the washable filter once a month. i have not yet had to change the main filter. the unit has a LED light that will come on when the main filter needs to be changed..
