Description

Heavy-duty, multi-purpose tri-lobe rotary blowers

The ROOTS® RAM Series features a straight tri-lobe design, which helps reduce vibration and delivers smoother operation with less pressure pulsation downstream compared to traditional bi-lobe models.

• Supports pressures up to 15 psig (1034 mbar)
• Vacuum up to 16” Hg (539 mbar)
• Flow rates up to 5810 cfm (9870 m³/hr)

Key Features

• Straight tri-lobe impellers for smoother operation and reduced pressure pulsation
  
• Removable steel mounting feet for flexible installation
  
• Precision-machined alloy steel timing gears
  
• Cylindrical roller bearings built for heavy-duty use
  
• Air-sealing piston rings
  
• Hydrodynamic lip-type drive shaft seal to prevent oil leakage
  
• Splash-lubricated spur gears and drive-end bearings for consistent performance

Benefits

• Smoother, Quieter Operation: Tri-RAM™ blowers use robust tri-lobe impellers with integrated shafts and a WHISPAIR™ discharge design that lowers noise and pressure ripple compared to traditional tri-lobe models.
• Built for Longevity: Featuring a one-piece cast casing, grey iron headplates, and involute-profile ductile iron impellers designed to handle demanding conditions.
• Leak-Resistant Sealing: Piston ring and lip-type oil seals minimize air loss and keep the lubrication system isolated from the air stream. A hydrodynamic shaft seal ensures no oil escapes at the drive end.
• Reliable Lubrication: Alloy steel timing gears are hardened, ground, and splash-lubricated at both ends for optimal performance and minimal maintenance.
• Flexible Mounting: Steel feet can be adjusted to accommodate both vertical and horizontal mounting needs, with extended shaft options to suit various outlet configurations.
• Warranty Assurance: Backed by a 24-month warranty from the date of initial startup or up to 30 months from the original shipping date—whichever comes first.
