SHEV cylinder
Cylinder
SHEV (Smoke and Heat Exhaust Ventilation) cylinders actuate smoke and heat exhaust systems in industrial buildings, stairwells, and public premises. The ZDRA 6/800 is a double-acting pneumatic cylinder with 800 mm stroke, designed specifically to drive roof lights and SHEV dampers. The complete mounting set comprises the pivot bracket ZDRA 6/SWB with two fittings and the swivel bearing ZDRA SLK for articulated wall attachment.
Installing a SHEV cylinder requires the cylinder itself (ZDRA 6/800) plus two mounting components. The pivot bracket ZDRA 6/SWB connects the cylinder to the roof light frame and compensates for angular misalignment via two fittings. The swivel bearing ZDRA SLK handles the opposite attachment point and allows free pivoting during opening. All three components form a coordinated mounting system.
Typical applications: Roof lights and SHEV dampers in industrial halls, warehouses and production facilities; smoke exhaust openings in stairwells and atria; pneumatically controlled facade and roof openings in public buildings; retrofit projects on existing SHEV installations.
