Radial blower aims for automotive market
A new brushless radial blower is aimed at automotive vehicle manufacturers for e-box and seat ventilation applications.
Compact blower performs quietly
Featuring a special design of spiral housing, the RL65 radial blower offers the advantages of a low noise performance combined with a very compact size.
The RER1 is aimed at small, high-powered electronics systems where air needs to be directed at high pressure to provide maximum possible cooling.
The RER1 requires a small inlet area that maintains a minimal requirement for space on the outside of customers' equipment.
A powerful maximum airflow of 190m3/h is provided by the blower and its noise figure is 74dB.

Fans of a quiet life
E Megafans are billed as the ideal choice for cooling solutions where lower power consumption and low noise are required.
Cooling fans go diagonal
When it comes to cooling systems for electronic equipment, axial fans no longer rule the roost, according to Papst's Engineering Director Ian McLeod.
A rotational speed of 6100rev/min is provided, and an operating temperature range of -20 to +70C is accommodated.
The unit consumes 23W and its running current is 1910mA.
Exhibiting versatility, the 12V blower can be fitted with a TTL tacho output signal or used with an analogue speed control input signal.
For durability and reliability, a life L10 figure of 60kh at 40C is returned.
The unit's blocked rotor and reverse polarity protection are standard, and further add to the reliability of the blower and the host equipment.
The RER1 blower from ebm-papst employs an electronically commutated external rotor motor.
The unit's motor electronics are completely integrated into the fan hub for compactness and protection, and EMI is kept to a minimum.
A very high quality ball bearing system and high specification balancing are employed in the construction of the blower.
The unit is expected to be designed into customers' systems.
Due to its specialised design, the blower cannot be added as a retrofit, as is often the case with an axial fan.
The host equipment needs to include the venturi to facilitate the pressure increase between inlet and outlet.
Alternatively if desired, the air can be allowed to spray out in a reduced-pressure 360-degree curtain around the blower.
The RER1 is a compact, high quality blower for use in special applications.
As a small volume product it offers higher quality than the limited range of similar competitors products, at a competitive price.
Particularly, the blower offers a long trouble free life with a low total cost of ownership - echoing ebm-papst's "fit it and forget it" ethos.
The RER1 meets approvals requirements as laid down by UL, CSA and VDE.
