PBM FOCUS ON EC FAN ONLY. Certificate: CE,UL,ROHS; Supply Ability: 100,000 pcs per year; MOQ: 1~100 pcs based on EXW price; 100 pcs above based on FOB price.
250mm EC Centrifugal Fan with Support Bracket, the PK3N250B2E-TZ0 is made especially for Laboratory and Analytical Equipment, such as chromatographs, spectrometers, mass spectrometers, PCR analyzers, gene sequencers, biosafety cabinets, fume hoods, centralized laboratory ventilation systems, and various high-precision analytical instruments and laboratory environment ventilation facilities. Through 915 Pa ultra-high static pressure forced airflow circulation, this active cooling core unit quickly dissipates heat from the enclosure, guaranteeing long-term reliability of baseline stability and detection sensitivity. It is appropriate for constant pressure exhaust control in biosafety cabinets and fume hoods.
PMB specializes in the development and production of superior EC/DC fans and intelligent airflow solutions that support fume hoods, biosafety cabinets, analytical equipment, and centralized laboratory ventilation systems.
