If you are looking for an affordable solution for semi commercial exhaust system, this is the one. It does the job and the seller was responsive. The suction could’ve been better but at the price point you can’t go wrong with it.
This confined space blower works very well. It was just that the area that I used it in was larger then expected. It still worked for the intended purpose.It was still a little loud, even in the area it was installed. It definitely moved the air.
I love this fan. No worries about breathing smoke or dust when I'm working on a project. The long vent duct attachment is a must have unless you have planes already for ducting.
I bought this one for size and air volume. Of course it's LOUD. You don't buy these fans for whimpy quietness. This thing is well built castviron impellor. Long durable flex duct. But a short cord length. It works like a smaller amoke ejector for those in the fire service.
Its a little bigger then what I expected, but totally fine.
It’s really strong, not to noisy, I just connected this week, the only thing I would like that comes with, is clips to hold the duct, because it comes with a rope to tight it.
