Full wind RB-71D-3 high-pressure blower 3kw/380V suction and supply vortex air pump in stock

　　Dimensions: 409 * 382 * 384

　　Vortex air pump configuration:

　　1. Shell material: The vortex air pump adopts ultra strong die cast aluminum, which is the same aluminum material as the Mercedes Benz wheel hub. Compared with ordinary aluminum alloy, die cast aluminum is stronger and has a lighter weight effect compared to iron shell fans.

　　2. Motor performance: The vortex air pump adopts a Taiwanese motor, which is a wideband, wide voltage motor. It is included in single-phase 110V/230V industrial three-phase: 220/380/415/660V, etc. The motor frequency can be adjusted from 45-75HZ, and the IP55 protection level is F-class insulation level. Its advantage is that domestic motors cannot achieve the same level of technology, and it is highly favored by domestic and foreign customers.

　　3. Fan oil seal: The vortex air pump adopts German MERKEL oil seal, and the German MERKEL material uses fluororubber that can withstand temperatures from -25 ℃ to 300 ℃. Compared to the general oil seal, its lip temperature is 20-50 ℃ higher than the working medium temperature during operation, making it more stable in performance, maintenance free, and has a longer lifespan.

　　4. Fan bearings: The core components of the vortex air pump use German SKF and Japanese NSK brand bearings, which can withstand up to 350 degrees Celsius and 4000 revolutions per minute. For domestically produced Luo axis, human centered bearings have stable performance, low noise, maintenance free, longer service life, and can ensure longer operation of the fan.
