High Performance Fans
High Performance Fans


High Performance Fans are ideal for applications which present the challenges of severe space limitations and/or higher static pressures that prevent the use of conventional fans. Typical uses include computer tape drive servo motors, densely packed printed circuit board arrays and duplicating equipment.

KB653: Within its recommended operating range (150 - 288 CFM), the KB653 fan provides more air than other fans of comparable size. It is also quieter, less costly and overcomes higher static pressures. It can be mounted to pressurize or exhaust the enclosure. (Pressurizing, with use of a filter, is preferred).

KOOLTRONIC also designs and manufactures a variety of fans to meet unique specifications. We invite your inquiries about our modification and custom-design capabilities.
