Handles volatile gases
Flexible use
Compact
RVK-EX 315D4#237943
Frequency: 50 Hz
Flexibility
The RVK-EX is intended to use for supply or extract air, designed to be installed in any position.
Reliability
The casing made out of conducting plastic is lightweight and hard-wearing. This makes it perfect for protecting against the damages of regular use and damp working environments. The combination of casing and motor construction ensures to minimize the need for maintenance of the fans and allows long continuous operation.
Performance
The RVK-EX can be used for zone 1 and zone 2; Field of application for gases of groups IIA, IIB and also hydrogen, temperature class T1, T2 and T3.
The type of protection is "Ex h" constructive safety.
Accessories
RVK-EX can be selected together with variety types of accessories as fast clamps, etc.

Features
Construction
The Casing made out of conducting plastic is lightweight and hard-wearing.
The RVK-EX 315D4 fan complies with the ATEX regulation
RVK-EX is certified under the no TPS 20 ATEX 085751 0009 X. Explosion proof version comply with EN 60079-0, EN 60079-7, EN 14986, DIN EN ISO 80079-36 and DIN EN ISO 80079-37.
Impeller
RVK-EX use backward curved radial impellers. These are dynamically balanced and paired with corresponding external rotor motors.
Motor
The fan is equipped with AC external rotor motor. The Motor is suitable for 50Hz.
Motor protection
The Motor has a prewired integral PTC thermistor with external leads to be connected to a motor protection device as U-EK230.
Control
The RVK-EX 315D4 can be controlled by reducing voltage via 5-step controller in combination with the Systemair Standard tripping unit U-EK230E EX.
Installation
RVK-EX can be installed in any position. Spigot with 25 mm length is perfectly designed to connect circular duct by fast clamps preventing vibration to the duct.
