STjh 30-inch belt-drive tube-axial fan with a medium propeller housing and enlarged external motor base on white.

STJH-TUBE-AXIAL-FLOW-FAN-30IN

Tube-Axial Flow Fan 30-Inch Belt-Drive

A medium-diameter inline axial fan for clean manufacturing heat removal and utility exhaust.

30 in propeller
10241 CFM reference airflow
0.4 in. wg reference point

Introduction de produit

The 30 in propeller and tube support materially more air than the compact model. A documented 3L30 reference operates near 10241 CFM at 0.4 in. wg, illustrating its use in medium-volume, low-pressure ventilation. Belt drive permits final speed matching to the system point, while the larger wheel and motor base require firmer supports and more service clearance than the 24 in assembly.

Key Features

Medium ventilation capacity

The larger blade swept area supports central utility branches beyond small equipment exhaust.

Adjustable belt-driven speed

Pulley selection allows final fan speed to be aligned with the required operating point.

Inline cylindrical flow

Straight-through inlet and outlet flanges integrate directly into round or transitioned duct sections.

Applications

For medium clean manufacturing utility exhaust, mechanical-room heat removal and low-pressure process-support ventilation.

Solutions for Your Application

Fan vibration is transmitted through a rigidly connected round duct.Use engineered supports, flexible connectors and vibration isolation while preserving correct inlet alignment.

Changing pulleys moves the fan beyond safe motor loading.Recheck brake horsepower and fan speed against the complete performance data before any field speed adjustment.

Options disponibles

Specify duty point, motor, pulley ratio, housing gauge, coating, access door, guards, supports, isolators and flexible connections.
