Heavy duty, round throttles are intended for cutting-off or control of the amount of flowing air, using round shutters. Throttle position can be controlled manually, electrically or with compressed air.

Throttles are adjusted to sizes of ventilation ducts of diameters of ø 200÷1250.  LSS throttles are made of hot galvanised carbon steel and – after prior arrangements – of seawater resistant aluminium alloy or stainless steel.
