The firebreak sash shutters are designed to leave the entire passageway in the pipe unobstructed. We produce several models:
STFRT: manual reset with crank handle, gravity closing;
STFRTPM: manual reset with crank handle, gravity closing with electro-pneumatic release;
STFRTMA: remote pneumatic reset, gravity closing with 24Vdc electromagnetic release;
STFRTPCMT (on horizontal pipe) STFRPCMTO (on vertical pipe): opening and closing with ISO pneumatic cylinders and a solenoid valve controlled by a spark or flame detection alarm.
