2DVO-0.7.60-366-4

Function and construction of 2DVO-0.7.60-366-4

The fan uses a two-stage counter-rotating aerodynamic arrangement. The metal housing and impellers form a compact unit intended for continuous operation in any spatial position. The two-stage design is a functional feature and must not be confused with visually similar single-stage DVO fans.

The fan is a component of the cooled equipment, not a self-contained ventilation system. Performance after installation depends on the resistance of the airflow path, unobstructed inlet and outlet, correct rotation and the electrical supply specified for the exact execution.

Electrical and airflow parameters

The documented nominal airflow is 70 m³/h at a total pressure of 500 Pa. Rated power is 37 W, current consumption is 0.23 A and rotational speed is 10,600 rpm. The average sound level is 77 dBA. These values apply to the complete 2DVO-0.7.60-366-4 execution, not to the family name alone.

Free-air airflow, total pressure and static pressure describe different operating points. They must be interpreted together and checked against the equipment passport rather than compared by one number alone.

Operating conditions and inspection

The stated operating range is −60 to +100 °C with relative humidity up to 98% at +40 °C. The fan is specified for vibration from 1 to 2,000 Hz at acceleration up to 100 m/s² and shock acceleration up to 400 m/s². The documented operating-time figure is 5,000 h.

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

Related cooling fans and selection

Functionally related products include 2DVO-0.7.60-367 and DVO-0.7-400. These links are provided for navigation within the cooling family and do not establish electrical, mechanical or installation interchangeability.

Application to a particular aircraft, helicopter, ground unit or electronic block must be confirmed by its illustrated parts catalogue, wiring diagram or approved maintenance documentation. Category placement alone is not evidence of installation on a specific platform.

Identification and ordering

The designation may be encountered as 2DVO-0.7.60-366-4; 2DVO 0.7.60 366 4; 2ДВО-0,7.60-366-4; 2ДВО0,7.603664. These are writing and search variants; any suffix, acceptance mark or execution code visible on the nameplate remains significant.

An inquiry should state the complete marking, quantity, required condition, delivery set and documentation requirements. Other models are listed in the Cooling & Ventilation Fans category. Availability and the presence of a passport or test record are confirmed for the offered item.
