RAS-J® Positive Displacement Blowers - Dresser ROOTS™

RAS-J series Whispair blowers are heavy duty units for continuous service featuring a proprietary design that reduces noise, pulsation, and horsepower levels over conventional blowers. An exclusive wrap-around plenum and Whispair™ jet eliminate rapid backflow of
air into the blower from the discharge area - a major problem with conventional blowers.
