Topic tags/keywords: air filtration air filtration garage shop powertec jet

Hey all,

so I want to install an air filtration system for my 2 car garage that I use for a workshop on the weekends. I ordered 2 of the powertec AF4000 400cfm max air filtration systems for $130 each. but now im wondering if i should just go with 1 unit like the Jet 1000 or the larger powertec ones that can produce 1044cfm.

is there any advantage to running 2 smaller systems over just 1? i don’t have a ton of room but i could make two systems work if i had to. but the 1 larger unit would obviously save me a little bit of ceiling space.

I went with two units after being dissapointed with only using one. They are located at opposite corners of the shop, with one on the ceiling and one on the floor. This gives me the best circulation and efficiency.

2 car garage (24’x24’x12’h) with the Jet AFS1000B mounted 1’ from the ceiling, 6” from the side wall with the intake about 8 feet from the corner. It meets my expectations and does a good job of circulating air which is key along with the number of air exchanges per hour (6-8 needed). The exhaust is located 4 feet from the wall mounted mini split to help circulate the conditioned air and as to some what pre-filter the air for the mini split. The Jet has 3 speeds, 3 preset times, on-board controls, and a remote.
The Jet is on sale at Woodcraft for $349 (2-04-19)
