How to Keep Your Fan Filter Unit Clean and Efficient with Exit Filter.


Fan filter unit, or FFU, is a type of device that is used to provide clean and filtered air to a specific area, such as a clean room, a laboratory, or a production line. FFU consists of a fan, a filter, and a housing. The fan draws the air from the environment and passes it through the filter, which removes the dust, particles, and contaminants from the air. The filtered air then exits the housing and enters the target area.

However, over time, the filter can become clogged and dirty, which can affect the performance and efficiency of the FFU. The clogged filter can reduce the air flow and pressure, increase the noise and vibration, and consume more energy. Moreover, the dirty filter can also release the trapped contaminants back into the air, which can compromise the cleanliness and quality of the target area.

That’s why you need an exit filter for your FFU. An exit filter is a type of accessory that is attached to the outlet of the FFU housing. It acts as a secondary filter that can catch any residual dust, particles, or contaminants that may escape from the primary filter. It can help to keep your FFU clean and efficient in many ways, such as:

  • It can extend the service life and reduce the maintenance cost of your FFU, as it can prevent the primary filter from getting clogged and dirty too quickly.
  • It can improve the performance and efficiency of your FFU, as it can maintain the optimal air flow and pressure, reduce the noise and vibration, and save energy.
  • It can enhance the cleanliness and quality of your target area, as it can ensure that no contaminants are released into the air.
