Fan filter unit specifications
Fan filter units are now available in varying sizes. There are two standard sizes of FFU (1175x575x300 and 575x575x300 mm). The size has a great effect on the air velocity of FFU, which is one of the most important factors when purchasing fan filter unit.
Have you ever been in a conversation with someone linked closely to a fan filter unit but gave up because you didn't understand the head or tail of what he was on about, or what was listed in the fan filter unit specifications list? We know it happens quite often, so we thought we'd break down some commonly heard basics as plainly and simply as we could for you.
1. Fan filter unit dimension
Fan filter units are now available in varying sizes. There are two standard sizes of FFU (1175x575x300 and 575x575x300 mm). The size has a great effect on the air velocity of FFU, which is one of the most important factors when purchasing fan filter unit.
2. Air velocity
The average air velocity is about 0.45m/s
3. Noise
The noise in non-unidirectional airflow must not be louder than 60dB, while the noise in unidirectional airflow must not be greater than 65dB. Therefore, when choosing fan filter unit, the noise level of FFU is as low as possible.
4. Airflow
The airflow of FFU is around 1000-1200 m3/h for FFU1175, and 600 m3/h for FFU575
5. FFU control system
DC motor is energy-saving and has a smart control, and lower noise, while AC motor has louder noise. The AC motor is much cheaper than DC motor.
6. Air filter
HEPA filter with efficiency up to 99.99% at 0.3 micron particles, ULPA filter with efficiency up to 99.99% at 0.1 micron particles
