EV-0.7-3660

Function and construction of EV-0.7-3660

The metal housing and single impeller form a compact axial fan that can operate on suction or discharge. It is designed for continuous duty in any spatial position and is mounted by either of its two support collars.

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 70 m³/h and total pressure is 200 Pa. Supply is 200 V, 400 Hz, three-phase. Power is not more than 17 W, current is not more than 0.09 A, speed is at least 11,000 rpm and sound level is not more than 65 dBA.

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 and relative humidity is up to 98% at +35 °C. The fan withstands vibration from 1 to 2,000 Hz up to 150 m/s² and shocks up to 400 m/s². Documented 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-0.5-1640. 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-0.7-3660; EV 0.7 3660; EV0.73660; ЭВ-0,7-3660. 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.
