EV-0.5-1640

EV-0.5-1640 single-phase high-frequency axial fan

EV-0.5-1640 is a single-phase high-frequency axial fan intended for cooling radio-electronic equipment from a 115 V, 400 Hz single-phase supply.

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 EV-0.5-1640

The fan is a compact metal axial unit for continuous duty. It can create airflow on suction or discharge and may operate in any spatial position, provided the inlet, outlet and mounting collars remain unobstructed.

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

Nominal airflow is 50 m³/h and total pressure is 180 Pa. Supply is 115 V, 400 Hz, single-phase. Power is not more than 16 W, current is not more than 0.16 A and speed is at least 11,000 rpm.

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

Operating temperature is −60 to +100 °C. The documented phase-shifting capacitance is 0.43 µF, sound level is not more than 65 dBA, weight is 0.15 kg and minimum operating time is 3,000 h.

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 EV-0.7-1640 and EV-0.7-3660. 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 EV-0.5-1640; EV 0.5 1640; EV0.51640; ЭВ-0,5-1640. 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.
