STJH-EC-CENTRIFUGAL-SUPPLY-AIR-FAN-310MM

Centrifugal Cleanroom Supply-Air Fan Unit 310 mm EC

The largest selected support-bracket supply fan, with a 310 mm wheel, higher-capacity EC motor and 0-10 V control.

310 mm impeller
0-10 V EC speed control
Expanded support frame

Perkenalan produk

The 310 mm EC centrifugal unit is intended for the higher-airflow end of compact AHU and fan-wall duties. Compared with the 250 and 280 mm versions, it has a visibly larger inlet cone, wheel and motor hub carried by an expanded support structure.

Fitur utama:

Higher-capacity fan cell

The enlarged wheel develops more airflow for a given number of modules in a cleanroom supply array.

Smooth demand control

A 0-10 V input permits continuous speed adjustment as filter resistance or room demand changes.

Direct plenum discharge

The support-bracket layout avoids a scroll housing and supports compact multi-fan arrangements.

Parameter teknis

Customization (Kustomisasi)	Voltage, motor loading, control interface and support geometry can be adapted to the intended application and operating environment.

Applications

High-airflow cleanroom supply sections, modular fan walls, process-air recirculation and large equipment plenums.

Solutions for Your Application

Too many small fan modules increase wiring and maintenance points.Use the 310 mm cell to achieve the required airflow with fewer appropriately selected modules.

Loaded filters cause the supply volume to fall below the room balance target.Connect the 0-10 V input to differential-pressure control and define a safe maximum speed during commissioning.

Pilihan yang tersedia

Pressure-control package, digital communication, protective screen, anti-vibration mounts and project-specific support rails are available.
