2x4 HEPA Fan Filter Unit is one of our main product.It is self-powered, and is self-contained modular, matching filters are easy to replace, so it is not restricted by the area; in the clean plant, it can be partitioned and controlled according to needs, replaced and moved as required.
The full name of ffu is: fan filter unit, is a self-powered air supply filtration device, with filtration effect of the modular end of the air supply device, is a terminal air filtration equipment module.
Principle
The air is drawn in using the fan (motor + impeller) inside the filter unit of the FFU fan. The absorbed air is filtered by the HEPA (High Efficiency Filter) or ULPA (Ultra High Efficiency Filter) filter below the FFU to filter out the large particles of dust in the air, and finally the fresh air is sent to the clean area at an even speed.
Composition
Cabinet: The material commonly used is galvanised aluminium alloy coated steel, aluminium alloy and stainless steel. The role of one is to support the fan and the air guide ring, the second is to support the flow guide.
Deflector plate: A balancing device for air flow, built into the interior of the box, around the underside of the fan.
Blower: Available in single AC (AC/1Phase), DC (EC/1Phase) and triple AC (AC/3Phase).
Control components: For AC FFU, five-speed governors or infinitely variable governors are commonly used; for DC systems, the control chip is embedded inside the motor and is controlled remotely with the help of special control software, computers, control gateways and network lines.
Features
1, Flexible and easy to replace, install and move
FFU is self-powered, and is self-contained modular, matching filters are easy to replace, so it is not restricted by the area; in the clean plant, it can be partitioned and controlled according to needs, replaced and moved as required.
2, Negative pressure ventilation
This is a unique feature of FFU. As it provides static pressure itself, the clean room is under positive pressure in relation to the outside world, so that particles from outside do not leak into the clean area, making sealing easy and safe.
3, Shorter construction period
The use of FFUs eliminates the need for ductwork and installation, shortening the construction period.
4, Reduced running costs
Although the initial investment is higher than using duct ventilation when choosing FFU, it is outstandingly energy-efficient and maintenance-free in later operation.
5, Space saving
Compared to other systems, the FFU system occupies less floor height in the air supply static pressure box, and basically does not occupy the clean room space.
A suitable solution for. Airborne substances, viruses and other fine particles in the nanoscale range are filtered out of the air with a separation efficiency of 99.995 % and the activated charcoal filter also removes odours. The integrated CO2 sensor alerts you should additional ventilation be required.

A fan filter unit (FFU) is a of type of air filtering equipment. It is used to supply purified air to cleanrooms or microenvironments by filtering out harmful airborne particles from recirculating air. The units are installed within the system's ceiling or floor grid. Large cleanrooms require a proportionally large number of FFUs, which in some cases may range from several hundred to several thousand units often contain their own pre-filter, HEPA filter and internally controllable fan air distribution.
