320VO-16-2

Cooling function and operating principle

An axial fan moves air mainly parallel to the rotation axis. In an equipment installation, the airflow removes heat from electronic assemblies and passes it through the designed duct, enclosure or ventilation path. Actual system performance depends on intake and outlet resistance, mounting clearances, rotation direction and the condition of the impeller.

For 320VO-16-2, the confirmed catalogue airflow is 3,000 m³/h and full pressure is 175 kgf/m². These are model-specific values, not generic figures borrowed from another member of the VO family. The catalogue specifies 5,000 operating hours and a 10-year service life for this suffix-free execution. The B version has the same main ratings but an additional aerointerlock replacement condition.

Electrical supply and rated performance

The documented supply is 220 ±11 V AC at 400 Hz (+12/−20 Hz). Rated power consumption is Not more than 2.5 kW, current consumption is Not more than 9.0 A, and rotational speed is Not less than 7,500 rpm. The sound level is Not more than 89 dBA. The complete electrical circuit, phase sequence, protective devices and connector arrangement must be checked in the applicable passport or equipment documentation before power is applied.

The listed dimensions are 222 × 302 × 342 mm. They are included for exact identification and installation planning, but they do not replace a dimensional drawing. The catalogue records an operating-time figure of 5,000 h and a service-life figure of 10 years.

Installation and maintenance checks

Before installation, inspect the housing, impeller, mounting points, electrical terminals or connector, protective elements and all markings. Confirm free rotation without energising the unit and check that the intended airflow direction matches the equipment duct. Never apply the supply values of a similar-looking model when the full designation has not been verified.

During maintenance, typical checks include contamination, unusual noise, vibration, overheating, current consumption and reduced airflow. Acceptance limits and test methods are determined by the product passport and the documentation for the serviced equipment. Disassembly, lubrication or replacement of an internal component is performed only where the approved maintenance data permits it.

Identification and ordering

Search and identification forms include 320VO-16-2; 320VO16-2; 320 VO 16 2; 320ВО-16-2. Cyrillic and Latin letters can look identical, but they are different characters in databases and search systems. The nameplate should therefore be compared character by character, including suffixes, punctuation and the technical-standard reference.

An enquiry should state the exact execution, required condition, delivery set and documentation. If available, add photographs of the nameplate, connector and mounting face. This prevents selection based only on airflow, voltage or body size and helps distinguish related products that have similar ratings.
