STjh 250 mm backward-curved centrifugal fan with a compact composite wheel and small motor hub on white.

STJH-BACKWARD-CURVED-CENTRIFUGAL-FAN-250MM

Backward-Curved Centrifugal Fan 250 mm

A compact 250 mm single-inlet free-running wheel made from high-strength composite for hygiene-sensitive air handlers.

250 mm composite impeller
Microbially inert wheel material
-20 to 80 C ambient range

مقدمة المنتج

This 250 mm backward-curved fan is the smallest selected composite Cpro size. The free-running single-inlet wheel is molded from high-strength, microbially inert composite and is suitable for compact hygienic air-handling compartments across a documented ambient range of -20 to 80 C.

الخصائص الرئيسية

Hygiene-oriented material

The composite impeller does not rely on a painted steel surface and is suited to air handlers requiring cleanable internal components.

Compact free-running geometry

The small wheel discharges into the plenum without a scroll housing, saving enclosure volume.

Backward-curved efficiency

Blade geometry supports stable centrifugal performance across a practical AHU operating range.

Applications

Small hygienic AHUs, cleanroom supply modules, return-air sections and compact recirculation cabinets.

Solutions for Your Application

A small AHU leaves little room for a scroll housing and discharge transition.Install the 250 mm free-running wheel in the plenum with a correctly aligned inlet ring.

Coated metal impellers are difficult to maintain in a hygiene-sensitive air path.Use the microbially inert composite wheel and include accessible cleaning clearances around the assembly.

الخيارات المتاحة

EC or AC motor pairing, inlet ring, support frame, guard, vibration isolation and pressure-based speed control can be provided.
