DC Blower

Pelonis Technologies manufactures and tests all of our products based on the highest standards of quality and reliability. We have an ISO-certified facility that employs flexible manufacturing techniques. This is one of the reasons that a mobile satellite communications company approached us to manufacture a DC Blower for one of their applications.

We were asked to design and build a blower that could adequately cool various system components. The blower had to stand up against moisture and dust in outdoor weather conditions on board a mobile vehicle. The customer had specifications that an environmental coating be applied to the blower’s circuit board to protect it from dust and moisture. In addition, a custom cable plug-in type connector and a special inlet guard also had to be coated for protection from the elements.

Our solution was to fabricate a high speed 24 volt DC blower with an aluminum enclosure that was coated with this special coating. Initially, the blower was provided without a protective inlet guard, but after testing by our engineers and the customer, we worked together to modify the design to add the guard where needed.
