Description

Durable, low-noise rotary blowers for demanding use

The RCS-J WHISPAIR™ series includes heavy-duty blowers with integral-shaft ductile iron impellers shaped with an involute profile. A specialized WHISPAIR jet and wrap-around plenum work together to reduce noise levels and lower energy consumption.

• Vacuum up to 24” Hg (810 mbar)
• Flow rates to 4080 cfm (6930 m³/hr)

Key Features

• Low noise operation with reduced power consumption
  
• Precision-machined alloy steel timing gears
  
• Cylindrical roller bearings for high-load durability
  
• Piston ring air seals to minimize internal leakage
  
• Lip-type oil seals to prevent lubricant intrusion
  
• Splash lubrication system for smooth gear operation
  
• Engineered for high volumetric efficiency

Benefits

• Robust Internal Components: Heat-treated and ground alloy steel spur gears are held securely with a locknut for long-term reliability, supported by heavy-duty cylindrical roller bearings.
• Leak-Resistant Sealing: Advanced sealing system with piston rings and lip-type oil seals helps contain air and keeps lubrication from contaminating the air stream. Hydrodynamic seals further prevent oil leaks at the drive end.
• Flexible Installation Design: Models 715J and 721J feature removable steel feet for vertical or horizontal installation. The top shaft is extended for side outlet setups, while both shafts are adaptable for top or bottom outlet configurations.
• Enhanced Acoustic Performance: WHISPAIR™ technology uses specially engineered impellers and a wrap-around plenum to regulate pressure changes, resulting in quieter, more energy-efficient operation.
• Warranty Assurance: Comes with a 12-month warranty from the initial startup date or 18 months from the original ship date, whichever occurs first.
