HEPA Fan Filter Unit Definition
HEPA fan filter unit is a device used to purify air and control environmental cleanliness. It is mainly composed of a fan, filter, control system, case, etc.
Fan
Driven by an AC motor, it is responsible for promoting air flow, sucking in and discharging air.
Filter
HEPA/ULPA filters are usually used, and the filter grades are generally H13, H14 ,U15 and U16. The higher the grade, the better the filtering effect, which can effectively remove harmful substances such as dust, bacteria, viruses in the air, thereby ensuring the output air is clean.
Control System
Including switches, speed controllers and other equipment, used to adjust the operating status of the FFU, such as starting and stopping the fan and adjusting the wind speed.
Case
Usually made of galvanized aluminum or stainless steel, it has excellent structural strength and appearance design. Its main function is to accommodate fans and filters and effectively protect internal components.

SYNRUI HEPA Fan Filter Unit Advantage
High stability: suitable for long term operation and environments that require continuous stable performance.
01
Low cost: technology is mature and the manufacturing cost is relatively low, which is suitable for projects with limited budgets.
02
Zoning control: HEPA fan filter unit in different areas can be adjusted independently, thereby avoiding full-load operation of the overall air conditioning system.
03
Cooling and heating modules: can directly adjust the temperature and humidity of the supply air, reduce dependence on external air conditioning, and improve energy efficiency.
04
Adjustable wind speed: speed regulation is generally carried out on site, with convenient operation and flexible adjustment.
05
Modular design: can be directly installed on the ceiling, reducing the layout of the air duct, thereby saving space and cost.
06
Strong compatibility: can be connected to the existing clean room system or used as a stand alone unit.
07
The outer shell is made of galvanized steel or stainless steel plate to effectively protect the internal components.
