2DVO-0.7.60-367

Function and construction of 2DVO-0.7.60-367

The fan uses a two-stage counter-rotating aerodynamic arrangement and is intended for continuous operation. Family members may differ electrically while retaining similar dimensions and external geometry. A photograph of a “-4” execution is therefore useful for identification but is not proof that every unsuffixed unit has the same supply circuit.

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

Nominal airflow is 70 m³/h, total pressure at nominal airflow is 490 Pa and rotational speed is at least 10,400 rpm. The stated average sound level is 72 dBA and RMS vibration velocity is 3 mm/s. Published family data lists 127 V and 220 V supplies and one- or three-phase executions; the 0.82 µF phase-shifting capacitance applies only where required by the exact circuit.

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 fan is rated for continuous duty from −60 to +100 °C, relative humidity up to 98% at +40 °C and atmospheric pressure from 2 to 150 kPa. It withstands vibration from 1 to 2,000 Hz at acceleration up to 100 m/s² and shock acceleration up to 400 m/s². The 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-0.7.60-366-4 and DVO-1-400. 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-0.7.60-367; 2DVO 0.7.60 367; 2ДВО-0,7.60-367; 2ДВО0,7.60367. 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.
