Direct Current FFU / DC HEPA Fan Filter Unit

Product features

PuriFan EC FFU has been widely used in semiconductor, electronics, food, panel display, biopharmaceutical and other fields with extremely strict air contaminant requirements. It is installed in turbulence and laminar flow cleanroom, to meet the requirements of Class 100, 10 and 1 classrooms.

Longer Lifespan: The use of quality DC motor technology ensures a longer service life, reducingmaintenance and replacement costs over time.

Total high static pressure

The use of high-pressure integrated fan allows the FFU to provide 50~150Pa external static pressure under rated airflow, which can be increased by using a low-resistance PTFE filter. Additional primary-efficiency filters can be equipped.

Extremely low chemical gas dispersion

To meet the special industrial needs, all component materials are made of low chemical gas dispersal materials and are rigorously tested. PTFE filters with even lower chemical gas dispersion are also available.

Easy installation

The overall design is flexible and can be fitted with any kind of ceiling framework without clamping device according to design specifications. The unit can also be used with gel seal ceiling framework when the filter has a knife-edge frame.

Low energy consumption

The brushless DC motor is more energy-saving than AC motor. Compared with the conventional AC FFU equipped with glass fiber filter, EC FFU can reduce energy consumption by 30% ~ 40%.

Unique structure design

The unique air duct structure design can improve the air outlet uniformity by 5-8%, increase efficiency by about 5%, reduce noise by about 5DBA, and reduce vibration by about 20%, reaching an overall efficiency of up to 58-60% and stronger overall structural cabinet strength.
