RVK fans are designed for installation in ducts. The housing is made of conductive plastic, the radial impeller is equipped with backward-curved blades. Combined with the Systemair U-EK230E motor protection relay, the speed of the RVK-EX 315D4 can be controlled via a 5-step voltage regulator. They are suitable for temperature classes T1, T2 and T3. Conveying of explosive gases in Zone 1 and Zone 2, as well as groups IIA and IIB, is also possible. The fans are certified under ZELM 03 ATEX 0198x. The motor of the RVK fans must be connected to a separate motor protection switchgear.

* Positive Temperature Coefficient = PTC (thermistor)
