TSK 1000

TSK is backdraft shutter suitable exclusively for circular duct. Installation is on the extraction of the fan, with using the extension piece possibly also at the fan inlet. The standard version is not tight, it is suitable for use in homogenized velocity field. The valve is not possible use in highly turbulent or vortex velocity fields or in cases of dynamic loading mechanism by changing the pressure conditions in the system. The flap can not be used for parallel operation of axial fans (to be used tightly constructed flaps). The flap is not designed for mechanical power transmission, or moments of distributions. The valve is made of galvanized stainless sheet in butterfly performance. From the sizes DN 630 has valve TSK on the blades counterweight and can be installed only in the horizontal duct. Dimensions check valves correspond to the flanges of duct fans TCB, TGT. TSKM flap is ready for mounting the actuator and is available only in sizes DN 630. By TSKM must always be open damper actuator before starting the fan and closed up after turning it off.
The backdraft damper is in standard performance is using to closed of flow the air into duct with temperature maximal 70°C and maximal pressure difference on the valve 150Pa. When the requirement for greater resistance in the reverse direction that fact must be discussed with the technical department (after working pressure communication is made necessary amplification of mechanical parts). Ambient temperature for the valve is from -20°C to 40 °C. The maximum permissible surface temperature of the bearings + 70°C. TSK flaps are designed for maximum airflow velocity 16 m/s. When the demand for higher speed or, in the case of inhomogeneous velocity field is made necessary amplification of mechanical parts based on the specifications. Flaps can not withstand mechanical shocks caused by strongly variable pressure ratios in ventilation systems or in systems with parallel operation of fans. The above information is not TSK-BR.
TSK check valves are fitted with flanges and are compatible with compact fans TCB and TGT. For installation, you must install the damper in the permitted direction of air flow. Indicated on the label flap.
