상품 소개

The FFU motor is the direct-drive power component fitted between the fan impeller and the electrical control system of a fan filter unit. Typical replacements use a compact external-rotor or electronically commutated construction to fit the shallow FFU plenum while supporting variable-speed airflow control. The shaft, flange, electrical connector and control input must be selected to match the original fan assembly. Balanced rotating parts and secure bearing support help limit vibration transmitted to the ceiling grid and final filter.

주요 기능

Compact motor geometry fits the restricted depth available above the FFU filter pack.

Variable-speed versions accept a matched analog, PWM or digital control interface.

Sealed bearings and a rigid mounting flange support stable direct-drive operation.

Multiple shaft, connector and flange arrangements simplify replacement in established FFU designs.

고객 제품 관심사

A replacement motor must restore airflow while remaining mechanically and electrically compatible with the existing FFU.

The replacement shaft or flange does not align with the existing impeller and mounting plate.Motor selection is matched to the original shaft diameter, projection, flange pattern and installation depth.

An incompatible speed signal prevents the FFU controller from regulating airflow.Available control interfaces are selected to suit the existing analog, PWM or communication controller.

Motor vibration is transferred into the ceiling grid and filter housing.Rigid bearing support and balanced direct-drive components reduce mechanical runout at the mounting interface.

Cable and connector differences delay field replacement.Connector pinout, cable length and lead termination can be configured for the target FFU assembly.
