0.63EV-1.4-32-4620 compact 27 V axial cooling fan with a separate control block

0.63EV-1.4-32-4620 is a compact 27 V axial cooling fan with a separate control block intended for forced-air cooling of electronic equipment in installations requiring a 140 m³/h airflow and a separate control block.

A fan moves air through a rotating impeller. For this unit, the exact designation, electrical supply, airflow, pressure and mounting data remain decisive.

Function and construction of 0.63EV-1.4-32-4620

The documented set comprises the fan and a separate control block. The two parts have their own dimensions and masses and must be checked as a complete delivery set when the product is ordered or replaced.

The fan is a component of the cooled equipment, not a complete ventilation installation. Air-path resistance, correct rotation, unobstructed inlet and outlet and the specified supply affect its installed performance.

Electrical and airflow parameters

The fan operates from 27 ±2.7 V DC. Documented airflow is 140 m³/h, speed is 10,800 rpm and current consumption is 2.55 A. The pressure figure is 32.4 kgf/m². These values apply to the complete 0.63EV-1.4-32-4620 execution.

Airflow and pressure refer to documented operating points and should be checked together. A visually similar fan with another suffix, voltage or frequency is not automatically interchangeable.

Operating conditions and inspection

The operating range is −60 to +70 °C with relative humidity up to 98% at +35 °C. The set is rated for vibration from 1 to 2,000 Hz up to 15 g and shock acceleration up to 150 g. Documented minimum operating time is 3,000 h and service life is 12 years.

Incoming inspection should cover the marking, housing, impeller, connector or leads, mounting points and free rotation. Unusual noise, vibration, overheating, current deviation or reduced airflow requires investigation under approved maintenance documentation.

Related cooling fans and selection

Functionally related catalogue positions include 0.5EV-0.71-20-4620 and 1.0EV-1.4-4-3270 U4. These links support navigation and do not establish electrical, mechanical or installation interchangeability.

Application to a specific aircraft, helicopter, ground unit or electronic block must be confirmed from its illustrated parts catalogue, wiring diagram or approved service documentation.

Identification and ordering

The designation may be encountered as 0.63EV-1.4-32-4620; 0.63 EV 1.4 32 4620; 0,63ЭВ-1,4-32-4620. These are writing and search variants; execution suffixes and nameplate marks remain significant.

An inquiry should state the complete marking, quantity, required condition, delivery set and documentation requirements. Other units are listed in the Cooling & Ventilation Fans category.
