## Description

Introducing the 3 Speed Remote Controlled Air Filtration System from POWERTEC. This low-cost shop air filter system provides high-end results, and effectively eliminates up to 99% of airborne particulates for your workshop. Using both, high caliber inner and outer filters, this system catches and abolishes contaminants, while circulating clean air into your working area. To help maximize its effectiveness with the amount of time and space you’re working with, it comes equipped with an adjustable 3-speed option – which can be operated manually on the unit, or by remote control (included). Unlike some air filtration machines, this unit not only possesses the power (1/6 HP) to get the job done, but it was carefully designed to work quietly in the background, for a non-disruptive working environment. Air Flow Speed Options: Choose from 300 350 400 CFM Infrared Remote Control: Allows you to control the power and set your preferred speed from across the room. Easy to Clean & Replace Dual Filter System: 5 micron disposable outer filter and 1 micron easy cleaning inner filter. Energy Efficient Time Saving: Using the built-in timer, you can program the unit to automatically shut off in intervals of 1, 2, or 4 hours. Mounting Rings: Possessing a lightweight design, the well placed and constructed mounting rings (eye bolts) make ceiling installation a quick and easy task. Specs Motor Size: 1/6 HP, 120V 60 Hz Motor speeds: 1200/1400/1750 RPM Unit Weight: Approx. 34 lbs. Sound Rating by Speed (from 3 Feet): Low 62 dB Med 67 dB High 69 dB

Review: Excellent air quality & a clean shop - I've got a basement woodworking shop and this is the perfect addition to keep my lungs clear and my machinery sawdust free. It comes all assembled you'll just need to mount it to your ceiling. It looks heavier than it is. I was able to install it by myself, although I'd recommend a second set of hands. Changing each of the two filters is super easy and its tool less to perform that task. It is pretty quiet too I've noticed in the rare moments there's no machinery running. I definitely recommend this air cleaner.
Review: Breathe Easy - I have a small wood working shop. I spend more time cleaning up dust than wood working. I have an excellent shop vacuum but it does not catch all the sawdust; some gets in the air no matter what. I use the Powertec Air Filtration System to capture some of the sawdust that escapes the shop vac. The Powertec Air Filter is very quiet and the remote works well. It shuts off when programmed and the programs are pretty simple. I placed the air filter on a high shelf rather than hanging it from the ceiling. It is not perfect; I still find sawdust on shelves and so forth but the air is much cleaner than it had been.

### ⭐⭐⭐⭐⭐ Works Well
*by O***U on October 28, 2025*

Works great. Took me a minute to figure out how to get the remote to work but once I did, its working fine. Quiet enough for my shop. I have asthma so cleaning the sanding dust etc., has become rather important to me.
