  • Copper disc design for high heat dissipation
  • Accurate control

The Wichita Kopper Kool airtube disc Clutches and Brakes are liquid cooled and consist of a series of alternating discs connecting an inner drive member to an outer drive member.

Engagement is achieved by pneumatic expansion of the airtube. This air-operated clutch contains copper discs for excellent heat dissipation and provides an accurately controlled continuous slip action for constant web tensioning. Tension levels are in direct

Design Features

  • New friction material lasts longer with less wear on mating copper.
  • Copper alloy wear plates increase heat transfer.
  • Hub spline provides perfect alignment of rotating discs.
  • External air & water connections.
  • Release springs ensure complete disengagement.
  • High strength reinforced neoprene air-tube offers long service life.
  • Optional long stroke air tube available on 18″ or 24″ size units to increase life and standard maintenance intervals.
  • High thermal capacity.

Notes

Maximum water jacket inlet pressure is 60 PSI. Brakes with as great as 50 % higher torque capacity is available upon request.

For mounting, use socket head capscrews conforming to the ASTM-574-97a.

1 Static torque will vary with temperature. Maximum air pressure is 100 PSI / 7 BAR. Minimum recommended air pressure is 3 PSI.
2 Static torque will vary with temperature. Maximum air pressure is 100 PSI / 7 BAR. Minimum recommended air pressure is 3 PSI.
3 Number of inlets and outlets are equivalent.
