Product Specifications
The positive displacement blowers in the Roots-FLO series are engineered for durability and efficient performance in industrial applications. These units feature piston ring seals to reduce leakage through shaft openings in the headplates and lip-type seals to prevent lubrication from entering the air chamber.
The basic construction includes a ribbed cast iron casing with rigid headplates, carburized and ground alloy steel spur timing gears secured to steel shafts with taper mounting and locknut, and cast iron involute impellers. Oversized anti-friction bearings are used, including a cylindrical roller bearing at the drive shaft to withstand V-belt pull.
