Classification of FFU

Classification of FFU Classification according to the external dimensions of the chassis According to the distance between the center line of the ceiling keel used to install the unit, the modal size of the chassis is mainly divided into 1200600, code 42; 1200900, code 43; 12001200, code 44; 600600, code 22; 7501500, code 25; other customer-specific non-standard sizes (custom-size.), (indicated by CS). FFU classification according to the different materials of the chassis* According to the different classifications of the chassis material, it is divided into standard coated steel plate (including galvanized, aluminized zinc, plastic spraying, etc.), code G; stainless steel plate, code S; aluminum plate (aluminum alloy plate), code A; other materials, code O. FFU according to the classification of motor mode According to the classification of motor mode, it can be divided into AC motor and brushless DC motor.

FFU is classified according to different control methods AC power supply units are classified according to the different control methods of the units into single condition units, indicated by S; multi-stage control units, indicated by M; step-less control units, including voltage regulation or frequency control, etc. This can default. FFU is classified according to the different static pressure of the unit According to the different static pressure of the unit, it is divided into standard static pressure type and high static pressure type. Standard static pressure type code is S; the high static pressure type code is H. Standard static pressure type is optional. FFU according to filter efficiency According to the efficiency of the high-efficiency filter, the unit can be divided into the high-efficiency filter, code H; ultra-high efficiency filter, code U; if the entrance of the unit has a coarse pre-filter, code P, without pre-filter can be defaulted.
