It looks to me like there is some small plenum area. The fans also look like they don't blow directly on the filter but blow into the chamber.

That's one of the ceiling mounted units you see in laboratories and cleanrooms that relies on either 1) exhaust fans under a grilled floor for laminar flow or 2) a sectioned off area of curtains that creates a high to low cascade... Better off building the right hood for that money.

The fans are clearly not blowing on the filter.

I think it looks like a decent unit.
