DVO-1-400

DVO-1-400 Single-phase high-pressure axial fan

DVO-1-400 is a compact single-phase high-pressure axial fan for cooling and thermal control of radio-electronic and other equipment. The confirmed electrical execution uses a 115 V, 400 Hz supply and must be connected according to its passport and wiring documentation.

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-1-400

The fan is built as a single-stage guide-vane and impeller assembly and is rated for continuous operation. Its compact housing resembles adjacent DVO models, but designation, current, rotational speed and connection must be checked independently. External similarity does not establish interchangeability.

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 confirmed rotational speed is 19,000 rpm. Maximum current consumption is 0.45 A from a single-phase 115 V, 400 Hz supply. Published data for this exact page does not provide a complete verified airflow and pressure pair, so those parameters must be taken from the product passport rather than copied from DVO-0.7-400 or another related model.

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-1-400 is specified for ambient temperature from −60 to +100 °C and relative humidity up to 98% at +40 °C. 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 2,000 h and the stated mass is not more than 0.135 kg.

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-0.7-400 and 2DVO-0.7.60-367. 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-1-400; DVO1-400; DVO 1 400; DVO1400; ДВО-1-400; ДВО1400. 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.
