Oil-Free, portable, full chemical-resistant, means less maintenance and no more frequent and costly oil change, or cross contamination. 7.8 cfm high capacity dry diaphragm vacuum pump with PTFE contact surfaces.

Applications:

The ideal oil-free vacuum pump for extra large size vacuum ovens (≥20 ft³), single buchner filters greater than 24" in diameter (or equivalent number of smaller sized funnels), and 50L or larger rotary evaporators (must use foreline or vacuum trap with vacuum oven if materials contain terpenes)
