FOCUS ON EC FAN ONLY
140mm DC single-inlet centrifugal fan made especially for cleanroom and air purification systems is the PS3N140B24M. When compared to conventional AC shaded-pole motors or inexpensive DC fans, its high-efficiency brushless DC motor provides 30% to 50% total energy savings under all operating situations. It is perfect for settings that are sensitive to noise because of its incredibly quiet 65 dB(A) operation. Low-power operation and on-demand purification are made possible by intelligent speed management. It can operate continuously around the clock thanks to its incredibly long lifespan of 50,000 hours.
In addition to supporting items like air purifiers, FFU filter units, clean benches, and biosafety cabinets, PBM specializes in the research and development and production of premium EC/DC fans and intelligent airflow solutions. PBM provides a variety of customized options to satisfy the various demands of manufacturers of cleanroom and air purification equipment.
