Technical Description

The 300mm DC Axial Fan is a medium-sized, high-airflow, speed-adjustable axial cooling fan that can be fitted into a range of devices. It has 7 blades, runs at 2200 RPM, consumes 156W of electricity, and produces 65 dB (A) of noise. It runs on 48 volts. This configuration performs well in the 300mm category, with acceptable noise levels and enough airflow. What is indicated by 65 decibels (A)? It will not be considered as loud when put in server rooms or equipment cabinets because it is about the loudness of a typical conversation.
It has a wide range of uses. Conventional applications include heating, ventilation, and air conditioning (HVAC); air filtration; and industrial drives. This fan can manage the large volume heat dissipation needed for data center cooling; it satisfies the high reliability requirements for cooling in buses and coaches, for which we offer solutions; and it works well in equipment that needs steady airflow, including biosafety cabinets. It can be combined with heat exchangers and condensers in some applications within the air conditioning industry, such as AHUs (Air Handling Units) for industrial buildings. In the field of ventilation and purification, it works effectively in situations like greenhouse ventilation that require constant air exchange.
This fan's adaptability is one of its main features. Based on the demands of the industry, customers can customize fan solutions by choosing their own accessories. Air baffles, housings, and mounting brackets may all be customized. We customize the parameters to satisfy each customer's needs, offering a range of sizes and performance choices. All things considered, this is a small axial fan with strong specifications, versatile uses, and the capacity to adjust to the requirements of different equipment.
