STjh 630 mm backward-curved centrifugal fan with a broad composite inlet ring and large motor hub on white.

STJH-BACKWARD-CURVED-CENTRIFUGAL-FAN-630MM

Backward-Curved Centrifugal Fan 630 mm

A large 630 mm backward-curved wheel with a broad inlet ring and large motor hub for central cleanroom air handlers.

630 mm large-diameter wheel
Composite family up to 16000 CFM
G2.5 balance quality

Introdução do produto

At 630 mm diameter, this is the upper selected composite wheel size and is physically distinguished by its broad inlet ring and substantial motor hub. The referenced composite family reaches airflow values up to 16000 CFM, while G2.5 balance quality supports use in large central AHU and recirculation sections.

Características-chave

Central-system scale

The broad wheel face supports the high airflow needed by large cleanroom recirculation and outdoor-air systems.

Large matched inlet

A properly proportioned inlet ring guides air into the wheel and limits losses at the expanded opening.

Heavy-duty support interface

The larger motor hub and frame provide the stiffness required for a 630 mm rotating assembly.

Applications

Large central cleanroom supply units, high-capacity recirculation sections, pharmaceutical AHUs and process-air plenums.

Solutions for Your Application

Parallel small fans create complex controls and occupy excessive wall area at central-system airflow.Evaluate the 630 mm wheel at the calculated duty and use fewer large assemblies where redundancy strategy permits.

A large free-running wheel can suffer inlet losses or structural vibration.Maintain the specified inlet-ring overlap, reinforce the motor base and verify isolation under operating load.

Opções disponíveis

EC drive, motor power selection, reinforced frame, inlet screen, monitoring sensors and redundant fan arrangement can be specified.
