High-Flow Vaneaxial Fan can serve diverse cooling applications.

Press Release Summary:

Able to develop necessary pressure to deliver 1,500–2,000 cfm against system impedance of 4–6 in. of water gauge (iwg), MAXIAX 9.25 is customizable for precise airflow design and meets reliability requirements of military applications. This 20 lb, 9.25 in. dia x 8 in. long fan is driven by aerospace-grade, 200 Vac, 3-phase, 400 Hz motor capable of developing nominal rotational speed of 7,700 rpm. Areas of use include airborne, vehicular, shipboard, and portable building applications.

Original Press Release:

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

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 (www.rotron.com). 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.
