Hepa box and fan filter unit are both purification equipment used in clean room to filter dust particles in air to meet the cleanliness requirements for product production. The outer surfaces of both boxes are treated with electrostatic spraying, and both can use cold-rolled steel plates, stainless steel plates and other outer frames. Both can be customized according to the specific requirements of the customer and the working environment.
The structures of the two products are different. Hepa box is mainly composed of a box, a diffuser plate, a flange port, and a hepa filter, and has no power device. Fan filter unit is mainly composed of a box, a flange, an air guide plate, a hepa filter, and a fan, with a power device. Adopt direct-type high-efficiency centrifugal fan. It is characterized by long life, low noise, no maintenance, low vibration, and can adjust the air velocity.
The two products have different prices on market. FFU is generally more expensive than hepa box, but FFU is very suitable for assembly into an ultra-clean production line. According to the process, it can not only be used as a single unit, but also multiple units can be connected in series to form a class 10000 assembly line. Very easy to install and replace.
Both products are used in clean room, but the applicable cleanliness of clean room are different. Class 10-1000 clean rooms are generally equipped with fan filter unit, and class 10000-300000 clean rooms are generally equipped with hepa box.
