As the air quality is getting worse and worse, the pollution is becoming more and more serious, and the standards issued by each country for all walks of life are becoming more and more strict, especially for some food processing, precision processing industries, etc., the problem of filtration in clean rooms more and more attention. For clean rooms, high-efficiency air outlets and FFU fan filter units are not unfamiliar. They are one of the most commonly used air-supply filter devices at the end of clean rooms.

Fan Filter Unit (FFU):

It is an air self-purification device, which can be installed on the indoor ceiling or placed on the bracket, so that the local level can reach 100.

Hepa box:

The 1000-level, 10,000-level and 100,000-level purification air conditioning systems are ideal terminal filtration devices, which can be widely used in purification air conditioning systems in medicine, health, electronics, chemical and other industries. Renovation and new construction of 1000-300000 grade clean rooms at all levels of the terminal filtration device is the key equipment to meet the purification requirements. Including static pressure box, diffuser plate, high-efficiency filter, and the interface with the air duct can be top-connected or side-connected.

Application range of Hepa box and FFU fan filter unit

They are all used in thousands, 10,000, and 100,000-level clean rooms. They are the terminal air filtration equipment of purification projects, and are the key equipment to meet the air cleanliness requirements of clean rooms. The FFU fan filter unit can be used in class 100 and class 10 clean rooms, while high-efficiency air outlets are generally not used in clean rooms of these classes. Both of these can be widely used in purification air conditioning systems in the pharmaceutical, health, electronics, chemical and other industries.

Hepa box differs from FFU fan filter unit in construction

A. Hepa box is a terminal equipment of the centralized air supply method. It is an unpowered device and needs to be equipped with an air duct.

Hepa box 4-piece set includes: Hepa box static pressure box, flange, high efficiency filter, air outlet diffuser.

B. FFU fan filter unit is a kind of purification and filter equipment with power unit.

It can be used alone or connected with air ducts, and consists of air supply box, flange, air deflector, fan, and hepa high-efficiency filter.
