Full wind RB-71D-4 high-pressure blower 4kw/380V variable frequency high-pressure air pump in stock

　　Dimensions: 432 * 382 * 384

　　High pressure vortex air pump configuration

　　(1. Shell material: The fan is made of ultra strong die cast aluminum, which is the same aluminum material as the Mercedes Benz wheel hub. Compared to ordinary aluminum alloy, die cast aluminum is stronger and has a lighter weight effect compared to iron shell fans.).

　　(2. Motor performance: The fan adopts a European style motor, which is a wideband, wideband 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, with an IP55 protection level and F-class insulation level. Its advantages are technology that domestic motors cannot achieve, and it is highly favored by domestic and foreign customers.)

　　(3. Fan oil seal: The fan adopts German MERKEL oil seal, and the German MERKEL material is made of fluororubber, which 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 fan are made of 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 and Japanese bearings, the performance is stable, the noise is low, maintenance is free, and the service life is longer, which can ensure that the fan runs longer.
