상품 소개

The EC centrifugal supply-air fan unit places a high-efficiency backward-curved impeller, electronically commutated motor, airflow sensing and flexible connections inside a rigid insulated cabinet. Direct drive removes belts and their wear particles, while variable speed allows the fan to compensate for filter loading or switch between occupied and setback airflow. Removable panels provide access to the wheel, motor electronics and isolation mounts from outside the air path.

주요 기능

The backward-curved impeller operates without a scroll housing and maintains stable efficiency across a broad cleanroom duty range.

Integrated EC speed control accepts analog or network commands without an external variable-frequency drive for smaller fan sizes.

Flexible inlet and discharge connections prevent casing vibration from transferring into rigid cleanroom ductwork.

An insulated double-skin cabinet reduces breakout noise and limits condensation on the casing during cold supply-air operation.

고객 제품 관심사

Cleanroom supply fans must overcome rising filter resistance while holding the scheduled airflow without adding unnecessary noise, vibration or maintenance debris.

Supply airflow falls as final filters accumulate dust, reducing room air changes and pressure.Closed-loop EC speed control increases fan output against the measured airflow or duct-pressure setpoint.

Belt dust and periodic tension adjustment are undesirable near a clean supply-air path.A direct-drive impeller eliminates belts, pulleys and routine belt alignment.

Fan vibration travels through the duct and becomes audible inside quiet cleanrooms.Spring or elastomer isolators and flexible connectors decouple the rotating assembly from the cabinet and duct.

A cramped plantroom prevents removal of the entire fan section for service.Large side panels expose the motor and wheel, while a slide-out fan base permits component replacement from one service side.
