PuriFan AC FFU with built-in fan filter unit
PuriFanACFFU is a self-contained fan filtration unit suitable for turbulent and laminar flow cleanrooms. It has high flexibility and is suitable for various ceiling joists and ceiling systems. Unique design, low noise, low energy consumption, high overall efficiency, all components are made of low chemical gas dispersion materials to meet some special industry requirements.
control system
PuriFan AC FFU can be equipped with a manual five speed speed controller or the latest AIX-I computer-based intelligent group control controller for flexible operation.
Accessory selection
Inlet primary filter, outlet diffuser plate, differential pressure gauge, pressure online monitoring, Particle online monitoring DOP test hole, air inlet connection, indicator light, online monitoring of wind speed, temperature and humidity.
Special structural design
The professionally designed casing has a stable structure and high strength, avoiding leakage and eliminating resonance when a large number of FFUs are operating simultaneously. The box is made of stainless steel material and can use disinfectants, making it very suitable for disinfection equipment. Aluminum zinc coated steel plate or aluminum box can be selected. An additional primary filter can be added.
Higher total static pressure can be achieved at maximum airflow
By using a low resistance puriCel II high-efficiency filter and combining it with the high total static pressure of the fan, it can increase the external static pressure by 50-150pa under rated airflow

Product characteristics
The new controller adopts the same communication protocol as the DC fan. Compatible with the DC fan control system.
The controller adopts physical transformer speed regulation. Instead of using thyristor voltage regulation.
The total distortion rate of current harmonics during controller operation is around 8%, which is similar to that of a DC fan. The traditional thyristor voltage regulation controller generates a large amount of current harmonics during operation. Usually between 30% and 60% THD. In the case of extensive use, it will cause great harm to the user's power grid.
The new controller eliminates harmonic problems and will not cause harm to the power grid when applied on a large scale.
This controller is suitable for all AC fans with a power not exceeding 200M.
Can be applied in new FFUs or renovation projects.
The communication method is the same as that of a DC fan. Connect the controllers together through Ethernet cables.
The transformer responsible for voltage regulation adopts high magnetic density silicon steel sheets and multiple turns ratio. Ensure that the transformer maintains no noise and ultra-low temperature rise during operation

By installing a new controller FFU, the communication network can be laid out according to the network architecture of the DC FFU.
The control system also adopts the same set, truly achieving compatibility between AC and DC
