The KVK Silent is a box fan designed for circular duct connections. Its casing is insulated with thick, high-density mineral wool, providing EI30 fire classification. The casing is constructed from Aluzinc, offering C4 corrosion resistance. The fan can be speed-controlled using a stepless thyristor or a 5-step transformer. It features integral motor protection with leads for connection to a motor protection device to prevent overheating. The KVK Silent can be installed in any orientation. The optional FK mounting clamp facilitates straightforward installation and removal, while also preventing vibration transfer to the ductwork.

Performance Diagrams
The document includes two performance graphs. The first graph illustrates the relationship between Static Pressure (Pstat) in Pascals (Pa) on the y-axis and Airflow (Q) in cubic meters per second (m³/s) on the x-axis. It displays multiple curves, indicating performance variations under different operating conditions or speed settings. The second graph plots Power (P) in Watts (W) against Airflow (Q) in cubic meters per second (m³/s), also showing multiple performance curves.
Additional data indicates Max efficiency: Hydraulic data 0,468 m³/s, Working air flow 344 Pa, Power 437 W, Speed 1372 r.p.m., Current 2,15 A, SFP 0,934 W/(l/s), Voltage 230 V.
