STJH-CIRCULAR-INLINE-DUCT-FAN-125MM-188M3H

Circular Inline Duct Fan 125 mm 188 m3/h

A quiet medium-diameter fan for small return-air and support ventilation branches.

125 mm duct size
188 m3/h maximum flow
30.8 dB(A) at 3 m

商品紹介

This 125 mm fan provides up to 188 m3/h with a 31.6 W motor. A documented sound-pressure value of 30.8 dB(A) at 3 m differentiates it for occupied support areas where the 100 mm fan may be undersized but a 160 mm high-flow unit would add unnecessary noise and duct size. Installed acoustics still depend on duct breakout, mounting and the selected operating point.

主要な特徴

Quiet support-air duty

The published acoustic value suits small occupied zones when the duct system is also treated.

Efficient medium impeller

A 31.6 W motor provides more airflow than the smaller 100 mm configuration.

Direct circular connection

The casing fits a 125 mm branch without separate square-to-round transitions.

Solutions for Your Application

Catalogue sound data is achieved in free field but duct breakout raises room noise.Assess the complete acoustic path and add isolation, lined duct or a silencer as required.

A controller incompatible with the motor causes hum or overheating.Use the approved speed-control method and verify minimum stable fan speed.

利用可能なオプション

Specify operating airflow and pressure, voltage, speed control, acoustic treatment, damper, mounting, connectors and access.
