Industrial EC centrifugal fan

The Ebm-Papst D1G133-AB39-22 is a new 133 mm EC centrifugal fan built for industrial cooling duties. It runs on 48 VDC with a nominal range of 36 to 57 VDC and draws 2.8 A at 105 W. The motor spins at 1780 rpm and is rated for ambient temperatures up to 60 °C with insulation class B.

Sealed ball bearing and IP42 protection

The unit ships as a single fan in its package. A sealed ball bearing supports the rotor while the motor is vibration-damped on both sides. The galvanised sheet-steel housing and impeller meet IP42 ingress protection. Rotation is clockwise when viewed toward the rotor. The painted black rotor surface and metal construction complete the mechanical assembly.

Suits 48 VDC industrial ventilation systems

This fan suits engineers integrating forced-air cooling into inverters, cabinets or HVAC equipment that supply 48 VDC. It does not suit builds that require a different voltage, a higher IP rating or a smaller footprint than the 190 x 180 x 170.5 mm envelope. Buyers needing variable-speed control should verify their controller compatibility separately.

Preguntas sobre este artículo

How often does the sealed ball bearing in the D1G133-AB39-22 need replacement?

The sealed ball bearing is designed for maintenance-free operation and does not require scheduled replacement under normal conditions.

Which limit appears first when the fan runs continuously at 1780 RPM?

The maximum ambient temperature of 60 °C is the primary limit; sustained operation above this temperature will trigger thermal protection.

What noise and heat levels should I expect when this 105 W fan runs all day at 48 V?

At full load the fan draws 2.8 A and dissipates 105 W; the motor is vibration-damped on both sides to reduce noise, while IP42 housing and insulation class B manage heat within the 60 °C ambient rating.
