COR-LOK® Air Shaft for Cantilevered Mounting with Built-in Toggle Valve Inflate/Deflate Operation

COR-LOK® toggle valve air shafts are a simple design that makes an exceptional contribution to efficiency by facilitating roll changeovers. Since the easily reached toggle valve is built right into the end of the air shaft the machine operator does not have to leave their station to access remote inflation controls or retrieve any tools. No inflating guns are required, no external inflate/deflate operators needed. This patented air shaft employs a standard rotary union for pneumatic hook-up and is specifically engineered for use in cantilevered applications. They are available in various diameters from 2" to 18".

Features and benefits:
  • Self-contained valve allows for operator freedom from remote air supplies
  • Facilitates roll changeovers
  • Available from 2" to 18" diameters
  • Typical application - narrow width cantilevered design for use on label and business forms presses such as Mark Andy, Webtron, Schriber and all narrow width cantilevered machines
  • Designed to fit your unwind or rewind stand
  • Backed by CAC's over 50 years of experience designing and manufacturing air shafts
  • Made in the USA
