DVO-0.7-400

DVO-0.7-400 Single-phase high-pressure axial fan

DVO-0.7-400 is a compact single-phase high-pressure axial fan for cooling electronic equipment and heating elements in thermal-control units. It is designed for a 115 V, 400 Hz supply and uses a phase-shifting capacitor in the specified single-phase circuit.

A fan transfers energy to air through a rotating impeller. For this product, that general principle does not replace verification of voltage, frequency, airflow, pressure, mounting and the complete designation.

Function and construction of DVO-0.7-400

The fan is built as a single-stage guide-vane and impeller assembly. Continuous operation is allowed, and published documentation also describes operation from a two-phase 115 V, 400 Hz sinusoidal supply with a 90-degree phase shift without the capacitor. The actual connection must follow the exact wiring documentation.

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 50 m³/h. At nominal airflow, total pressure is 245 Pa and static pressure is 167 Pa. Power consumption is not more than 35 W, current consumption is not more than 0.33 A and rotational speed is at least 13,800 rpm. The average sound level is not more than 73 dBA.

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

DVO-0.7-400 is rated for continuous operation 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 100 m/s² and shock acceleration up to 400 m/s². The operating-time figure is 2,000 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 DVO-1-400 and 2DVO-0.7.60-366-4. 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 DVO-0.7-400; DVO0.7-400; DVO 0.7 400; ДВО-0,7-400; ДВО0,7400. 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.
