Howden Roots manufactures a range of cast iron blowers, with capacities up to 2300 cfm (3900 m3/h) and pressures up to 15 psig (1 bar g). These blowers provide reliable, long life with oil free operation. We carry an extensive range of Roots blower packages for a wide variety of applications and industries.
Universal RAI series Howden Roots Blowers feature a convenient grease lubrication (or a dual splash oil lube, if needed) on the drive end. The feet allow for easy in-field adaptation to either horizontal or vertical configuration along with any of four drive shaft positions - top, bottom, right or left hand. All frame sizes are center-timed to allow for rotation in either direction. Units available include: URAI, URAI-DSL, URAI-G, URAI-J DSL, and URAI-J.
DESIGN AND CONSTRUCTION FEATURES
Roots RAM, RAM J, RAM GJ and TRILOBE AM-X Howden Roots Blowers, are recognized as the most volumetrically efficient positive displacement blowers in the industry. All standard units are center-timed to allow rotation in either direction. Units are available in frame sizes 404 thru 624, and all models feature "universal" mounting feet, which allow each unit to be mounted in four different configurations (top, bottom, left and right-hand configurations). Piston ring seals reduce leakage through shaft opening in located within the headplates. Additional lip seals prevent lubrication from inadvertently entering the air chamber. Units available include: RAM, RAM DPJ, RAM DVJ, RAM GH, RAM J, RAM VJ, and Trilobe RAM-X
Roots RCS series Howden Roots Blowers are heavy-duty units with integral-shaft ductile iron impellers in an involute profile. The headplates, gear cover, drive end cover and rigid, one-piece casing are grey iron. Carburized and ground alloy steel spur timing gears are taper mounted on the shafts and secured with a locknut. Cylindrical roller bearings combined with high volume oil reserves offer low maintenance and trouble free operation. Piston rings reduce air leakage through the headplate shaft openings, while lip-type oil seals maintain lubricant in the roller bearings. All RCS series blowers are equipped with splash oil lubrication at both ends of the blower. Units available include: RCS-H, RCS-J, RCS-JH, RCS-JV, RCS-JV/H, and RCS-V.
Patented ROOTS-FLO positive displacement blowers are heavy duty rotary units in a compact sturdy design engineered for reliable pneumatic conveying of grain and similar product. The basic model features a ribbed cast iron casing and ridged headplates, carburized and ground alloy steel spur timing gears secured to steel shafts with a taper mounting and locknut, and cast iron involute impellers. Oversized anti-friction bearings are used, with a cylindrical roller bearing at the drive shaft to withstand V-belt pull. Detachable rugged steel mounting feet permit easy in-field adaptability to either vertical or horizontal installation requirements. The ROOTS-FLO is splash lubricated from oversized oil reservoirs. ROOTS exclusive gearbox design improves oil distribution and lengthens bearing and gear life.
RAM Whispair Series Howden Roots Blowers are available in 7 different models. All models feature "universal" mounting feet, which allow the unit to be mounted in four different configurations. Roots Whispair blowers feature quieter operation when compared to conventional units operating under the same conditions.
