Overview


Hydraulic Dashpots

  • Used on heavy straight lift fire curtains to slow the last few feet of descent. May be needed to meet code require- ments that the last 8 feet (2.4 m) of travel take 5 or more seconds.

  • Provides 10′ (3 m) of damping using a double purchased 5′ (1.5 m) piston.

  • 12″ (304.8 mm) diameter sheave for 3/8″ (9.53 mm) dashpot cable.

  • The dashpot is rigged in a double purchase arrangement with a cable which is snatched by the fire curtain arbor when the curtain is nearing the floor. The dashpot cable pulls on the sheave at the top of the piston rod of the hydraulic cylinder. A fluid flow adjusting valve is preset to provide the appropriate retarding force on the piston, braking the descent of the curtain. The piston and cylinder automatically release the oil to return the unit to an “at rest condition” when the curtain is raised.
