Cooling & Ventilation Fans

Aircraft cooling and ventilation fans are indexed for searches by complete model designation and installation context. The category covers fan units recorded for equipment cooling, air circulation and ventilation functions on aircraft. Closely related models can differ through one letter, number or climatic suffix, so the full marking should be preserved.

VO, EV and DVO fan designations

The inventory includes VO-series units, EV and DVO executions, 50VTS-18-2AL and aircraft-numbered products such as 8A-6311-00 Series 4. These examples illustrate the catalogue’s varied numbering systems. They do not establish common dimensions, airflow, voltage, rotation or installation.

Operating data must match the installed equipment

A valid fan selection can depend on supply characteristics, airflow requirement, pressure, speed, mounting, connector, direction of rotation and environmental execution. Use only parameters confirmed for the exact model. Compare the label with the equipment manual, wiring diagram and aircraft documentation.

• record the full designation and climatic suffix;
• state the cooled equipment or ventilation function;
• include documented electrical parameters;
• describe mounting and connector details;
• send quantity, required documents and label images.

Submit the fan identification data

The matching product page is the starting point for confirming identity, available condition, completeness, documents, price and lead time. Related helicopter environmental equipment appears in Mi-8 / Mi-17 Heating and Ventilation. Other aircraft components are available in the main catalogue.
