Fan: back centrifugal fan, aluminum alloy impeller, low voice and low vibration.

HEPA filters: mini pleated glass fiber HEPA filters efficiency 99.99% H14 standard; Air velocity adjustable; Noise≤58dB; average air velocity≥0.45±20%m/s; air flow rate: 500-1500m3/h adjustable;

Pre filters on the air inlet side to remove large dust and protect impeller from damage.

Air duct in the interior of ceiling HEPA unit to prevent uniform airflow.

The application of ceiling HEPA unit;

For most of the class 100, 1000, 10000 cleanroom in hospital, factorial work line, laboratories, pharmaceuticals and so on.

About the installation:

For loading, transporting, unloading the FFU, please ensure it`s vertical standing;

Don`t drop it when unloading;

For maximize the service life, FFU should not be installed in place where too much oil, dust, moist and so on;

Please left enough space between two FFU;

The ceiling HEPA units are installed on the ceiling grid sealed by self weight.

Maintain: checking the running situation, cutting off the power recourse for any abnormalities.

Do not disassemble any component of the FFU; Do not step the central part;
