Help me find the perfect fan for this filter
    #26568874 - 03/31/20 11:21 AM (3 years, 9 months ago)

Hey I want to build a flow hood  using  this filter
https://eklimag.ro/filtru-absolut-hepa-clasa-h14-305-x-610-x-292-mm-mp141224m2-general-filter-italia.html
Can anyone  help me with choosing the right  motor fan for this? Or at least explain  to me what and where to calculate?
Thank you

So i converted to inches and the filter in your link is around 12 x 24 inches and about 12 inches thick. (if you choose this filter also make your plenum about 12" thick so you can build the static pressure)

Simple calculation on the filter is 1'*2'=2  So you want a blower capable 200CFM @ 1.2" of static pressure (SP).

(true calculation 12" * 24" = 288"  , 288"/144" = 2' , 2' * 100fpm = 200 CFM)

IMO you can get something bigger than 200 cfm @ 1.2" SP and just dial it down with a rheostat/speed controller or simply covering up the intake.

:hmm:

after looking at it again i am understanding that 12" filters allow much more airflow than 6" filters.

If i understand the specs of that filer right it will allow ~300 fpm at 1.0"water gauge . so you would actually need a blower producing 200 CFM at  ~.5"static pressure rather than the 1.2" of SP i mentioned in my above post.

Thank you, so if I buy a 300 CFM and put in a control variator,  would  that be ok? Also thinking  in adding a pressure sensor  so I dont burn the motor  in case it gets plugged,
Edit:
Would  this work?

Most commonly flow hoods use centrifugal blowers but that fan will probably work. it has 3 speeds and looks like at its fastest speed it will hit close to the marks you'll want with that filter.

as i look at its chart it is hitting 375 or 380 cubic meters per hour at 149pa. a flow rate of 200 cubic feet per minute is ~340 cubic meters per hour and 149 pa is .6"water gauge static pressure

Im not sure about a pressure switch, i haven't seen anyone use one. i assume if your filter was plugged you would notice as no air would come out.. but that seems unlikely anyways as they usually just accumulate a build up over time and the air flow slowly drops. Use a pre filter.

I would like to point out the i am making an assumption that the filter you have linked will operate at 100 cfm at .6" static pressure or equivalent 149 pascals but i have not seen any stats on the static pressure and im not sure how the listed pressure drop equates.

in any case i would advise a second opinion before you drop a bunch of money on this project as i am no expert.

I'm asking  a lot around,  I might  hey a bigger fan and install a control  unit on it and take it from there, I'm planning  in adding a pre filter for bigger  particles,  but still working  on a plan

I think youre on the right track but i dont have much experience with those 12" thick filters. They're generally used for scrubbing whole rooms and so allow for much more airflow.

in any case please let us know how it works out. always interesting to see how a flow hood comes together.
