Fan filter unit

What is a fan filter unit,and what is it used for?

A fan filter unit can be regarde as a intergreted air filtration equipment,which is widely used in clean room filtration system.Combination of a fan,a moto
r,air filters and a control unit make the FFU become an independent air filtration device,not only can be used alonely,but also be used at scale.
Fan filter units are installed at ceiling,as clean air flow diffusers for clean rooms.They can make the clean room stay at a positive static pressure status.As a laminar flow diffuser,the FFU push the air from ceiling to floor unidirectionally. This is the most efficient mode for modern cleanrooms to quickly clean the air,by squeeze down the original air to return air grilles.

The advantages of FFU and why you should use it:

1.Flexible.Cus FFU is an independent air filtration device with fan and motor,there is no place area restriction for where it is installed.You can not only install FFU at a clean room ceiling,but also use it alone at any area you need.
2.Short clean room building period.Installing fan filter units cost less time than building air ducts
3.Save space.
4.High efficiency,easy control and maintenance.
5.Supply static air pressure
