OVERVIEWPelonis Technologies’ innovative Micro Blowers are uniquely engineered for high quality, value and per-formance to meet the needs of today’s demanding applications.

THE NEED FOR MINIATURE COOLINGToday’s industries for cooling products require devices that are increasingly smaller, lightweight, have low power consumption, and reduce heat generation.

Micro Blowers are ideal thermal cooling solutions for applications that have limited space with restricted power budgets. They manage heat generation effec-tively, are energy efficient, and have a long operating life.

AXIAL AIR-GAP COOLING Traditional blowers include silicon steel motors with radial air-gaps. Miniaturization is difficult, operation is inefficient, and power loss is greater at higher tempera-tures.

By using Axial Air-Gap Technology, Micro Blowers are smaller and more energy efficient than traditional blow-ers and have almost no power loss at higher tempera-tures.

Micro Blowers can be used in a variety of applications, including:

Portable medical devices Portable computers and electronics LED lighting Smartbooks and tablets Portable HDD IP cameras High-speed memory modules CCTV security surveillance systems Pocket projectors Micro fuel cells GPS devices Portable gas/particle detectors Portable plasma generators Portable air-quality monitoring devices Ventilation and defrosting Mask/Helmet/Glass ventilation Solar and wind energy devices

Micro Blowers are ideal alternatives to traditional fans and blowers and can be customized to satisfy a variety of applications that require an effective miniature cooling solution.

TRADITIONAL FAN TECHNOLOGYTraditional fans and blowers have silicon steel stack motors with radial air-gaps that are PERPENDICULAR to their axis. This makes miniaturization difficult.

AXIAL AIR-GAP TECHNOLOGYMicro blowers operate without silicon steel stack motors and have axial air-gaps that are PARALLEL to their axis. This makes them ideal miniature cooling devices.
