EV-0.7-1640

Function and construction of EV-0.7-1640

The metal fan can operate on suction or discharge in continuous duty at any spatial position. It is mounted by either support collar. The complete designation must be distinguished from the three-phase EV-0.7-3660 execution.

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 115 ±6 V at 400 Hz, single-phase. Power is not more than 18 W, current is not more than 0.25 A and speed is at least 11,200 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 and relative humidity is up to 98% at +35 °C. The fan withstands vibration from 1 to 1,000 Hz up to 100 m/s² and repeated shocks up to 400 m/s². 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-0.5-1640 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-0.7-1640; EV 0.7 1640; EV0.71640; ЭВ-0,7-1640. 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.
