One last thing you might consider is putting an UV-C lamp between the blower and the filter. Any 'nasties' that get trapped in the filter get killed quickly by the UV-C which also helps extend the life of your filter.

Anno, does the airflow change directions in your flowhood before it hits the filter? From this pictures, it doesn't appear so. If it does not, the air pressure will not be even across the filter causing one area of the filter to blowout before the rest. You really want to have the high pressure air from the blower enter from the top or side (relative to the filter), not from directly behind the filter.

He stated that he had the air coming in through a tube, or piping. The blower is not directly mounted to the hole in the back.

This one:

It looks like the hole directly behind the filter is where the air comes in... could just be my eyes crossing :smile:

The hole is at the top, and the air hits the wooden frame, then goes down toward the filter.

Nice idea with the gauges. I wasn't aware that they could be gotten so cheap. Think I'll get one.
If you do get a multi-speed from Ebay you can probably make due without a rheostat as one of the speeds should get you within a nice operating range.

On the UV-C note. I have an extra fixture with bulb if someone is interested in trading or buying it. I managed to get 2 from a custom lighting manufacturer before they stopped making them.

that one is pretty much the same price, and exactly ~200CFM at .8", although with the prefilter it will end up being like 1.2", correct? Will that blower not be powerful enough?

ok I know this is a little off topic but here is something that I have been bidding for on ebay. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=3258&item=3103840908

My maximum bid was $50 and I had the auction but I think they person running the auction bid on them becuase my high bid wasnt high enough. The same person keeps buying them and then the guy runs the auction again. There is one up for auction currently, it is for five units. If anyone wants to bid on them let me know and I will go in on it with you.

possibly not because that is what a reserve price is for. if you really suspect this then report it to eBay and they will investigate it. sorry for the OT but it's good info for anyone on eBay.

I made and used this flowhood for years. . ..

www.fungifun.org/flowhood


I moved to a new house - with a higher spore count and it doesnt seem to produce contaminate free substrates anymore.

Here is the one I built this week. I built it to be more 'enclosed' where I work - I hope it helps - BTW my prefilter is an automotive air filter for a truck.
