The new RL Series rotary lobe blower from Thomas brings the benefits of “Roots blower” technology toa unit measuring just 6 in. long and weighing only 1.75 lbs. The unusually small size is made possiblethrough a patent-pending assembly process that greatly minimizes leak paths within the blower chamber.RL Series blowers provide high flow at low pressure and are ideal for applications including fuel cells,laboratory pressure and vacuum sources, air samplers, gas boosting, and a variety of portable air-movingdevices.Because rotary lobe blowers are contact-less with nointernal wear surfaces, the RL Series blower generatesvery little heat, is very efficient, and provides long,service-free life. A 12V brushless DC motor andprecision permanently lubricated timing gears carry thelong-life approach throughout the unit’s design.Despite its small size, the RL Series blower delivers airflow up to 1.90 cfm (538 lpm), pressure to 2 psi (0.14 bar) and vacuum to 4 in. hg (-135 mbar). It can bemounted either vertically or horizontally and is equipped with standard 3/8 in. O.D. hose barbs and a 6 in.wiring harness.
