Laminar Flow Cabin with FFUs is made of special aluminum profiles and stainless steel frames. Cabins are either designed to be hanged from ceiling or comes with rolling wheels. Transparent hygenic curtains, variable speed controller, differential pressure gauges, test aerosol nozzles are some of the standard accessories. LF units achieve Class 100 conditions according to U.S. Federal Standard 209E or ISO Class 5 according to ISO 14644-1 with speed controlled fans, pre-filter and HEPA filter (Hl 4).

Clean-air velocity is about 0,45 m/s (±%20) measured 15-20 cm under the air distributor. Laminar flow cabins with FFU supply laminar flow achieving positive pressure in the unit.

Operation principle

The LF Unit takes the air from surrounding environment of the unit. Air passes through the perforated grilles and prefilter. 100% of overal air goes through HEPA Filter and perforeted SS air distributor into the entire of working space. It ensures positive pressure inside the unit with laminar flow.
