How to Choose a Fan Filter Unit for Your Cleanroom

The fan filter unit can be used in modular connections, making FFU widely used in clean rooms, clean benches, clean production lines, and assembled clean rooms. To choose and buy the right FFU, we must first understand the basic components of FFU (fan filter unit). FFU is mainly composed of three core components: fan, high-efficiency filter, and box. The quality of these three components is directly related to the performance and price of FFU. In order to maintain the normal operation of the clean room and reduce the frequency of FFU failures, we suggest comprehensive consideration of the following aspects.

Fan

FFU fans are divided into AC motors and DC motors. The initial purchase cost of DC FFUs is higher than that of AC FFUs. After a period of use, DC FFUs are lower than AC FFUs in terms of power distribution costs, energy consumption costs, and clean room operating costs. After about 1 to 2 years, the initial investment of FFU can be recovered, and a large amount of cost can be reduced for the enterprise every year thereafter. In addition, FFU fans are divided into outer rotors and inner rotors. Generally speaking, inner rotor motors are more suitable for FFU and have higher cost performance.

Cabinet material

The material of the FFU cabinet is also one of the factors that affect the cost of the FFU. Commonly used plates for FFU production include aluminum-plated catalpa plates, cold-rolled steel plates and stainless steel plates (SUS201, SUS304, SUS316, etc.). Different materials will affect the price and cost of FFU, and the prices of the above materials will increase in turn. The thickness is generally 0.8~1.5mm. The production of FFU belongs to thin plate welding, which requires high welding and grinding skills of welders, so it is best to choose experienced welders.

High-efficiency filter

The high-efficiency filters configured in the FFU purification unit have different filtration efficiencies from H13 to U15, which are also one of the cost factors that directly lead to the price of FFU. The higher the filtration efficiency, the higher the cleanliness control, and the user can choose according to the cleanliness of the specific clean room used.

Others

In addition to the above factors, we also need to consider factors such as the noise level, control method, and size of the FFU, because basically multiple, even hundreds, or thousands of FFUs are used together, and noise and control methods are particularly important.
