Classification of Fan Filter Unit
1. FFUs are classified according to different control methods
AC power supply units are divided into single condition units according to different control modes, represented by S; Multi condition gear control unit, represented by M; The stepless control unit, including voltage regulation or frequency conversion control, can be omitted.
2. FFU is classified according to different static pressures of the unit
According to the different static pressures of the unit, it is divided into standard static pressure type and high static pressure type. The standard static pressure type code is S; The high static pressure type is designated as H. The standard static pressure type can be omitted.
3. FFU varies according to filter efficiency
According to the efficiency of the high-efficiency filters carried by the unit, they can be divided into high-efficiency filters, with the code H; Ultra efficient filter, code named U; If the unit inlet has a coarse pre filter code P, it can be defaulted if there is no pre filter.
4. Classify according to the external dimensions of the chassis
According to the distance from the centerline of the ceiling keel used for installing the unit, the modular size of the chassis is mainly divided into 1200 * 600, with the code 42; 1200 * 900, code 43; 1200 * 1200, code 44; 600 * 600, code 22; 750 * 1500, code 25; Non standard sizes (custom size, represented by CS) customized by other customers.
5. FFUs are classified according to different chassis materials
According to the different materials of the chassis, it is classified into standard coated steel plates (including galvanized, aluminum zinc coated, spray painted, etc.), with the code G; Stainless steel plate, code S; Aluminum plate (aluminum alloy plate), code A; Other materials, code named O.
6. FFU is classified according to the motor mode
According to the motor classification, it can be divided into AC motors and brushless DC motors. The code for single-phase AC motor is A1; The code for the AC three-phase motor is A3; The code for brushless DC motors is EC.
The diverse classification of FFU provides rich choices for different application scenarios. Whether in high demand clean spaces in large-scale industrial production or in specific environments in precision laboratories, the most suitable FFU type can be found based on actual needs.
