The fan filter unit is a very important device in modern cleanroom systems, it can generate a laminar airflow from the ceiling up to down. the inside fan can help airflow pass the filter easily to overcome the resistance of the HEPA filter/ULPA filter.

• Housing: Galvanized steel, Stainless Steel
• Motorized: AC/EC, 110/220V
• Air filter: with HEPA/ULPA filter and Pre-filter
• Cleanliness level: class 100 at least
• Size: customized or standard
• Control: centralized or single manual/remote
• Application: special designed for cleanroom
• HEPA filter efficiency: H13, H14, U15

110V/220V

To meet the different powder supply requirements of our clients, we offer two versions of the FFU power system, which are a 110V Motor and a 220V motor. All the motors are CE tested and qualified that can use for at least 10 years.

AC or EC motroized HEPA filter

For cleanroom FFU quantities less than 100 units, we recommend our clients use AC motor FFU. The AC motor is easy to control and won`t spend too much cost to build the cleanroom in the initial time.

for FFU quantity over than 100 units, an EC motorized HEPA filter is a better choice, the EC FFU can be controlled centralized via computer, which is really easy to control and can monitor the status of each FFU.

Also, the EC Fan filter unit spends less power consumption than AC.

Typical Application

Mainly for large size class 100 cleanroom

The birth of FFU is for large-scale clean room air purification. Considering there are lots of HEPA filters that should be installed on the ceiling if there is no motor to help airflow pass HEPA filters, there will only have a little airflow to the inner cleanroom area.

for softwall or hardwall cleanroom

the softwall and hardwall cleanroom is a temporary clean room built to save cost and time. In order to meet the requirements of cleanliness, it is also necessary to install FFU on the top.

To build a laminar flow hood

the Fan filter unit is the core part of the laminar flow hood, with an FFU can build a laminar flow hood for some applications like the lab, mushroom cultivation, phone/laptop repair, and so on. We have a solution for those clients that can help them build a laminar flow hood easily with our FFU.
