BMF Filter Fan Units and Accessories

Filter fan units of different dimensions are used in a variety of cleanroom technology applications. These filter-circulation devices are used primarily in cleanrooms, cleanroom booths and cleanroom tents. Filter fan units are also often installed in mini environments, flow boxes and a variety of cleanroom-specific special solutions, be it for creating a vertical or a horizontal flow of ultra-pure air.

BMF Cleanroom Technology (BMF Reinraumtechnik GmbH) is an experienced and certified manufacturer of cleanroom infrastructure. Our portfolio includes not only cleanroom booths in a modular design but also all kinds of installations and cleanroom components.

Our TC 350 EC 1157 Filter Fan Unit is a quality product manufactured in our Reutlingen production facility that was developed based on years of experience in cleanrooms with turbulent mixed aeration or laminar displacement flow.  The core element of the unit is a modern, smooth and quiet DC motor from German manufacturer Ziehl Abegg, controlled via a 0-10 Volt interface. The integrated power supply allows for problem-free individual control or managing with group controllers.  The TC 350 EC 1157 casing is made from robust aluminium, the low weight allows for easy and effortless installation. The filter fan unit fits into all BMF cleanroom ceilings and is compatible with a number of other ceilings.
