The RL48-19/12/2 blower is designed to provide the answer to space restricted situations where airflow against high back-pressure is required.

As a radial blower turns the air through 90 degrees between inlet and output, it does not need a clear space behind it as would an equivalent sized axial fan.

Thus it can be easily located in densely packed equipments in applications such as telecommunications, storage systems and electronics with high levels of integration.

Specific examples include photocopiers, induction hobs, power supplies, projectors, test equipment, in car electronic systems and portable equipment.

Measuring a diminutive 75.7 x 75.7 x 27mm the blower offers an air performance of 28m3/h and will operate against back-pressures of up to 190Pa at a nominal speed of 4400rev/min.

The unit operates from a 12V DC supply, with a voltage range of 10.8 to 13.2V allowing users to fine tune their system supply for optimum operating conditions.

The RL48-19/12/2 consumes 5.3W with an operating current requirement of 440mA.

Offering versatility, the RL48-19/12/2 includes a tachometer output for fan speed control, and reverse polarity protection for reliability.

The blower is able to operate over a temperature range of -20 to +55C with a degree of protection to IP20.

Weighing only 74g it is an ideal cooling device for many types of portable and handheld equipment.
