Centrifugal case fan with metal scroll housing and backward-curved impeller

Fans

Fans G2E140-AE77-01 G2E140-NF33-07 230V 105/115W centrifugal case fan

SKU CH-H62D-Z4X1B

A 230 V centrifugal case fan delivering 105 W at 1400 rpm or 115 W at 1500 rpm with CE approval

  • 230 V AC operation suits mains-powered enclosures
  • 105/115 W draw at 50/60 Hz for strong airflow
  • 1400/1500 rpm speed range with external-rotor motor
  • CE-approved design meets European safety standards
  • Variable voltage control allows adjustable fan speed

Industrial centrifugal fan

The Fans G2E140-AE77-01 and G2E140-NF33-07 are 230 V AC centrifugal fans rated at 105 W at 50 Hz and 115 W at 60 Hz. They run at 1400 rpm and 1500 rpm respectively with a 22 µF capacitor rated at 450 V. The units are new and built with an external rotor motor for compact integration.

Suited for fixed-voltage industrial cooling

These fans suit engineers maintaining equipment that specifies a 230 V AC supply and can accommodate the 140 mm motor frame indicated by the model code. They are not for PC builders who need a low-voltage DC fan, nor for anyone requiring PWM speed control or standard motherboard fan headers. The fixed line frequency and capacitor-start design limit use to mains-powered enclosures.

230 V AC nominal voltage

The single specification that decides fit is the 230 V AC nominal voltage at 50/60 Hz. Only systems wired for mains voltage with provision for a 22 µF run capacitor should use these fans.

Questions about this item

How do I wire the 22 µF 450 VDB capacitor when installing this 230 V centrifugal fan?

Connect the capacitor in series with the motor winding as shown on the nameplate; ensure the 230 VAC supply matches the 50/60 Hz rating and observe the 0.46/0.51 A current draw.

What maintenance will the external-rotor motor and crimped impeller need over time?

Periodically clean dust from the backward-curved blades and verify the impeller spins freely; the motor is cooled by airflow through the rotor so unobstructed intake is essential.

At what ambient temperature does this fan reach its thermal limit during continuous operation?

The maximum ambient temperature is 40 °C at 50 Hz and 35 °C at 60 Hz; exceeding these reduces motor life and may trigger thermal protection.
