Product Description

The Rotork Fairchild Model 4900A is a High Flow Pneumatic Volume Booster designed for high precision applications. With Cv of 9 in both forward and exhaust modes, this pilot operated booster provides fast response, very low deadband and high precision control. In its pilot operated regulator design, the M4900A handles up 250 psig [17 BAR] (1700 kPa) supply pressure and delivers an output pressure up to 150 psig [10 BAR] (1000kPa). The Fairchild Model 4900A Booster provides a flow capacity of 500 SCFM [850m3/Hr], which equates to a Cv factor of approximately 9 in both forward and exhaust modes.
  • Fast response for quick valve opening and closing times
  • Highly accurate valve control for your system
  • Provides excellent pressure control
  • Provides efficient dynamic reverse flow characteristics
  • Provides high accuracy, sensitivity and excellent low pressure performance
  • Provide efficient leak free operation
  • Prevents changes in control characteristics when supply pressure changes
  • Provides very stable operation
  • Provide convenient access to the outlet for additional control accessories and pressure monitoring
  • Allows for easy collection of exhaust air or use of a silencer
  • Certification for use in all Canadian territories and provinces
NOTES: Oil free air must be applied to the regulator. Use a filter to remove dirt and entrained liquid in the air line ahead of the regulator. If an air line lubricator is used, it MUST be located downstream of the regulator, to avoid interference with regulator performance.
