What is Fan Filter Unit?

A Fan Filter Unit (FFU) is a motorised unit, which helps in the air filtering process and provides clean, filtered air to a cleanroom. Fan filter unit is a flexible and economic solution, which provides purified or filtered air to clean rooms, laboratories, manufacturing units, medical facilities and much more by removing harmful particles present in the air.

FFU or Fan Filter Unit comes integrated with HEPA filters or ULPA filters, fan and control systems. Air is supplied using the fan, through a pre-filter and then via the integrated HEPA or ULPA filters. This process helps in filtering the air of any airborne particles or sub-micron particles, which ensures that pure and filtered air is supplied in the clean room.

The FFU unit is usually installed within the system’s ceiling or floor grid and creates a positive room pressure. Not only this, Fan Filter Unit for clean room is a more energy efficient route than using an Air Handling Unit (AHU).

How does Fan Filter Units Work?

HEPA Fan Filter Unit for clean room is typically available in 2’ x 2’ or 2’ x 4’ size options, which is best suitable for a clean room of 500 to 1000 CFM (Cubic Feet per Minute). An FFU unit can be easily fitted in the ceiling grid of the same size and dimensions. Fan Filter Unit for clean room helps in the filtering of the air.

An FFU draws the air via a motorized fan, which passes through the pre-filter and then through HEPA or ULPA filter to remove any sub-micron particles present in the air. This process helps in a continuous supply of clean and processed air supply. The Chempharm India HEPA Fan Filter Unit removes particles down to 0.3 microns at 99.995% efficiency.

An Electronically Commutated Motor or ECM is also installed with the HEPA filters, which helps in controlling HEPA speed by using electronic controls. Not only this, it also helps in monitoring HEPA filter health and sends a filter pressure drop or failure notification as well. This can also work along with a Programmable Logic Controller (PLC), which can help you maintain the consistent velocity with the increase of pressure drop across the filter.
