Industrial axial fan for 400/480 VAC systems

This Ebm-Papst A2D250-AA26-80 is a three-phase AC axial fan built for 400 VAC or 480 VAC supply at 50 Hz or 60 Hz. It suits industrial HVAC enclosures, cabinet cooling and machinery ventilation where a 250 mm metal frame and IP44 protection are required.

Replaces worn or failed three-phase axial units

The jump is worth it when an existing 250 mm fan shows bearing noise, reduced airflow or insulation degradation. Ball-bearing construction and class F insulation restore rated airflow at 2520 rpm on 50 Hz or 2920 rpm on 60 Hz with 140 W or 220 W draw respectively.

Verify voltage, phase and mounting before ordering

Confirm the supply is three-phase 400 VAC or 480 VAC and that the 250 mm cut-out, bolt pattern and airflow direction A match the enclosure. The unit weighs 2.2 kg and needs an IP44-rated environment; no capacitor or speed controller is included.

Questions about this item

What mounting dimensions does the 250 mm metal frame require?

The fan has a 250 mm diameter metal housing with five sheet-steel blades; allow clearance for the full 250 mm sweep and the 2.2 kg weight when planning the cut-out or bracket.

How do I wire the three-phase 400/480 VAC motor correctly?

Connect the three-phase supply to the motor terminals matching 400 VAC at 50 Hz or 480 VAC at 60 Hz; the nameplate shows 0.25 A / 0.30 A and 140 W / 220 W — verify rotation direction after power-up.

When should the ball bearings be inspected or replaced?

The motor uses sealed ball bearings rated for continuous IP44 duty; schedule inspection after extended high-temperature operation or if vibration and noise increase beyond normal 2520/2920 RPM levels.
