RLM E6-6371-4Y-23-P PLUG FAN

Direct driven high-performance centrifugal fan RLM in explosion proof execution with PREMIUM EFFICIENCY motor in efficiency class IE3

Complete assembly module, specifically developed and optimized for operation without a casing. With flameproof enclosure motor Ex db eb & PTC-thermistors for drive (VFD) operation. Newly developed high performance impeller with optimized shape and highest efficiency, comprising six backward curved hollow section true aerofoil blades with real turbulence profile and rounded, inclined blade leading edges from impeller shroud to back plate, for optimal impact over the entire width of the blade. Co-rotating radial diffuser with optimized exit curving on the cover disc to enhance efficiency. Impeller made of high-tensile sheet steel in an automated manufacturing process, robotic welding, coated, fixed to the shaft of the foot motor. balanced statically and dynamically according to DIN ISO 21940-11. System inlet cone made of copper or with copper ring, equipped with flow measuring device IMV as a standard feature. At intake a square flexible connection can be fitted, as a standard feature with safety guard on the inlet. Complete module optimally adjusted, built to a common base frame prepared for vibration decoupling. Fan can only be used with a horizontal axis! Performance data (w/o drive) according to tolerance class 2 to DIN 24 166. The fan does meet the requirements of ATEX regulation 2014/34/EU by its safe design h and controlled production procedures corresponding to DIN EN 14986:2017 and DIN EN ISO 80079-36/-37:2016. Classification is made to group II, category 2G, explosion group IIB, temperature class T4 and EPL Gb.
