DV-404A
Ventilation drive
Description
DV-404A aviation fan
DV-404A is a dc motor-driven ventilation unit used to create controlled airflow in the installation specified by the applicable aircraft or equipment documentation. The complete designation is the primary identification key: housing size, motor appearance or a shared voltage does not establish interchangeability.
A fan converts motor power into airflow, but the installed result depends on pressure, duct resistance, mounting and operating conditions. This card separates confirmed data for DV-404A from general family information.

Function and documented application
Application: Aircraft ventilation equipment; exact installation is confirmed by the aircraft parts catalogue. The source basis is existing passport-derived Aviamisto record and public aviation component lists. Where an aircraft type is named, it describes documented use and does not make every modification or installation automatically compatible.
In operation the fan works together with the power circuit, protection devices, wiring or connector, mounting hardware and the airflow path. Correct polarity or phase sequence, clear inlet and outlet paths and secure mounting are necessary for a meaningful functional check.
Identification and related equipment
The suffix A is part of the identity. Because available records distinguish values for the drive without an impeller, the complete supplied assembly and its passport must be confirmed before installation. Closely related catalogue positions include DV-1KM and DV-3. These links support navigation and system comparison; they do not state that the products are interchangeable.
When checking a removed unit, record the complete nameplate, suffix, serial or drawing reference, connector, airflow direction and mounting dimensions. Photographs of the label and installation position are useful when several visually similar executions exist.
Installation and maintenance checks
Before installation, inspect the housing, impeller or propeller, motor, fasteners, connector or leads and mounting points. The rotating assembly must move freely without contact, deformation or foreign objects. Electrical tests must use the documented supply and protection limits.
Maintenance checks normally cover contamination, unusual noise, vibration, current draw, temperature and actual airflow. Disassembly, lubrication, balancing or component replacement should be performed only under an approved procedure for the exact execution.
Ordering DV-404A
An enquiry should state the complete DV-404A marking, quantity, required condition, delivery set and documentation. Condition, test scope, production date and included accessories are confirmed for the offered unit. More products are listed in the Cooling & Ventilation Fans category.
