High Flow Vaneaxial Fan for Avionics, Semiconductor, Heat Exchanger and Building Applications

Press release date: Mar 13, 2013

AMETEK Rotron MAXIAX 9.25 is robust and customizable

A new vaneaxial fan designed for high performance cooling with powerful airflow has been introduced by AMETEK Rotron ( The MAXIAX 9.25 can develop the necessary pressure to deliver 707-944 Liters per second (L/s) [1500 to 2000 cubic feet per minute (cfm)] against a system impedance of 0.99-1.5 kilo Pascals (kPa) [4 to 6 inches of water gauge (iwg)]. This makes it well suited for applications including centralized forced air electronics cooling in aircraft, forced air delivery in semiconductor processing equipment, air circulation in environmental control systems and as a heat exchanger cooling fan.

Applications include:
• Military and general aviation avionics
• Semiconductor processing
• Environmental control systems
• Heat exchangers
• Portable buildings

Its light weight (9.07 kg / 20 lb) and compact size (23.5 cm diameter x 20.3 cm length / 9.25” x 8”) are appropriate for airborne, vehicular, shipboard and portable building applications. Its high rotational speed delivers air-moving capacity comparable to pallet-sized industrial blowers. The MAXIAX 9.25 is designed to meet the reliability requirements of military applications and is easily customizable for precise airflow design.

The MAXIAX 9.25 is driven by a high speed, aerospace grade 200VAC, 3 ph, 400Hz motor, developing nominal rotational speed of 7,700 RPM. It can also be paired with a power conversion module to allow for operation from alternate power sources.

AMETEK Rotron is a world leader in brushless DC motors, blowers and pumps for aerospace, military, mass-transit, medical and computer applications. It is a unit of AMETEK, Inc., a leading global manufacturer of electronic instruments and electromechanical devices with annual sales of more than US$3 billion.
