The FFU is the abbreviation of the fan filter unit. As we know, it is the necessary equipment in the clean room. In this post, we will share with you some knowledge about the fan filter unit.

 

What is the fan filter unit?

The fan filter unit is a self-powered air supply filter device, a modular terminal air supply device with a filtering effect. The fan filter unit sucks in the air from the top and filters it by HEPA. The entire air outlet surface can send clean air.

The fan filter unit is necessary equipment for the clean room

The fan filter unit is the simplest purifying equipment consisting of a fan and HEPA filter and the most basic air purifying equipment. Due to the one-to-one correspondence between the HEPA filter and fan, a negative pressure area is formed outside the unit to enable a negative pressure sealing function.

FFU may be used separately or in combination to achieve higher cleanness easily. FFU can improve the cleanliness of the sterile area greatly and is one of the ideal auxiliary equipment for the clean room.

The working principle of the FFU
