Radial blower is powerful and quiet for in-cabin and e-box applications in vehicles

Release date: May 2005

Designed to meet the demands created by the increased level of electronics in modern vehicles, ebm-papst Automotive & Drives’ RV40 brushless radial blower is aimed at automotive vehicle manufacturers for e-box and seat ventilation applications. The blower combines high power cooling with quiet running, offering increased passenger comfort and safety.

Two models are available suffixed H or L signifying high or low power. The 4.5W RV40-18/12H offers nominal speed and airflow figures of 5,000-1 and 16.5CFM, and the 2.3W RV40-18/12L, 3,900min-1 and 10.6CFM respectively.

The RV40 DC radial blower has an electronically commutated external rotor motor with fully integrated commutation electronics, so no external control circuitry is required. As an EMI compliant device, the blower can be connected directly to the supply voltage.

With a life span five times longer than competitors’ brushed motors, the brushless RV40 features a spiral housing and a blower wheel made of fibreglass reinforced plastic for low weight, quick startup/acceleration, and quiet operation for ‘in-cabin’ applications.

Providing long life and high reliability, the RV40 has overvoltage and reverse polarity protection, so it will not be damaged by supply line voltage spikes/variations or mis-connection following maintenance. The blower’s nominal operating voltage is 12V, however a range of 9 to 16V is accommodated.

Able to operate in an ambient temperature range of -20 to +70 degrees C, the RV40 boasts a service life of 25,000 to 70,000hrs dependent upon operating temperature.

The increased use of electronics in vehicles creates more heat that has to be dissipated. This factor together with increased passenger comfort and safety are driving the demand for this type of high performance, specialised product from ebm-papst.

The RV40 is designed and manufactured in Europe, features a CFD designed impeller, electronic commutation and ball bearing system for long life, and benefits from ebm-papst’s 40 years experience and legendary build quality in fan and motor design.
