Flowhood Consistency
    #27047416 - 11/19/20 02:26 PM (3 years, 2 months ago)

Hey! So I obtained a flowhood recently and I'm noticing that one specific spot of the hood is blowing air significantly harder then the rest of the hood. I have another larger filter that I was planning to switch the motor to eventually. What I want to know is if the current set up is still safe to use for the time being for work. Thanks!

I'm assuming you bought the FH pre-built? How deep is the plenum/HEPA filter? you could test how well its working with a spread of open plates in front for like 20 minutes and see if anything grows on them

Plenum is 12 inches and the heat is about 6

A significant change in airflow on the face of the HEPA filter could indicate a hole or tear in the filter media.

You can see the center of the area circled also has the separator fins mashed down really only in that area, might have been accidentally hit with something and has an obvious tear on the other side that you can't see.

It's not an ideal situation at all. If you are stuck with it, avoid that area of the filter by as far as possible. A new filter would be a good idea.

Shiieeeeet. I'll get to building the new one asap then. Gotta do some agar work though so I've got my fingers crossed

Hey just wanted to update this thread.

I ended up doing 20 plates. One of which was just a straight up test plate that I opened and moved around the spot with higher flow. All of the plates came out clean with no problems.
