This document describes the ebm-papst 422 J/2M device, an axial fan designed for conveying air. It serves as a built-in component, intended for integration into larger systems.
The 422 J/2M is primarily designed for air conveyance, operating with an airflow direction that exhausts air over its struts. The impeller rotates counterclockwise when viewed from the rotor side. The motor automatically restarts after a mains failure or when a blockage is eliminated, provided voltage is applied. This self-starting capability necessitates caution during operation and maintenance. The device is a built-in component and lacks an integrated power disconnecting switch, requiring external means for power isolation during work.
The product is intended for use in sheltered rooms with controlled temperature and humidity, avoiding direct exposure to water. It must be operated with all protective equipment in place and should not be put into operation before being fully installed in the customer's application. The operating manual must be observed at all times.
Prohibited uses include:
An in-situ assessment is required for heating behavior, protection against contact, electrical shocks, impact of foreign objects or water, and usage at altitudes higher than 2000 meters. Speed control via the supply voltage is only permitted within the stipulated supply voltage range; PWM-based speed control is not permitted. Only cables designed for the current and ambient conditions specified on the nameplate should be used, ensuring adequate mechanical protection.
Regular maintenance is crucial for the longevity and safe operation of the device.
Safety Inspections:
Cleaning: The product should be cleaned carefully with a moist cloth, without applying pressure to the rotor. Avoid cleaning agents containing acids, caustic solutions, or solvents, as these can damage the product.
Storage: The device should be stored in its original packaging in a dry place, protected from weather and vibration, and in a clean environment. It should be protected from environmental effects and dirt until final installation. To ensure trouble-free operation and the longest possible service life, the device should not be stored for more than one year. Even devices intended for outdoor use should be stored as described prior to commissioning.
Extended Non-Operation:
In case of faults, the product should be replaced rather than repaired. If damage is visible, the product should not be started. The product bears the CE and EAC marks, indicating compliance with relevant European directives.
