Axial Fans & Ventilation for Enclosures

Ventilating, or providing air flow through your enclosure can be accomplished a couple of different ways. Passive ventilation requires only the addition of louvered openings properly located on your enclosure. Passive ventilation incorporates the theory of convection cooling in which heat is transferred by the natural, upward flow of hot air from the device being cooled. In our enclosure applications, the warmer air inside the enclosure escapes through louvered openings positioned towards the top of the enclosure. As this occurs, cooler outside air is naturally pulled in through louvered openings positioned on the lower area of the enclosure.

Moving higher volumes of air through your enclosure will require the use of forced ventilation. Forced ventilation for enclosures incorporates the use of fans. Fans are typically installed on the exhaust side of the enclosure ventilation system, forcing warm, internal air out of the enclosure. This creates a suction effect on the air intake side of the ventilation system, forcibly pulling outside air into the enclosure. Large volumes of air can be forced through your enclosure, with fans available in a wide range of CFM capacities and a variety of voltages.
