Laboratory vacuum pump L-BL2

liquid ringportableoil-free

Product overview
The L-BL2 is a compact, air-cooled liquid ring vacuum pump delivered as a ready-to-operate "Pump in a Box" unit. It provides 100% oil-free, contact-free compression with a closed water circuit, eliminating the need for fresh water supply during operation. The patented discharge-air cooling limits temperature rise to ≤ 15 K above ambient, making the L-BL2 suitable for humid environments and continuous-duty applications while maintaining reliable performance up to ~95 % vacuum and a typical flow range of 27–275 m³/h.
