The pumping action and deep vacuum comes from the movement of PTFE diaphragms within PTFE heads. All wetted services in the flow path are made of fluoroplastic making the BTpro pump highly chemically resistant. As a result, the BTpro vacuum pump series is near-zero maintenance. A cold trap placed in-line with BTpro pump is needed if terpenes are part of the flow path.\u003c\/p\u003e\n\u003cp\u003eThe BTpro40 and BTpro70 models employ patented valve and diaphragm technology that generates a deep 15 Torr vacuum pressure with each PTFE head. In addition, both pump models have built-in tuneable vacuum to control evaporation rate. The tunable vacuum adjustment can also be used to stop accidental bumping\/foaming.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cstyle type=\"text\/css\"\u003e\u003c!--\n.tg  {border-collapse:collapse;border-spacing:0;}\n.tg td{font-family:Arial, sans-serif;font-size:14px;padding:7px 5px;border-style:solid;border-width:1px;overflow:hidden;word-break:normal;border-color:black;}\n.tg th{font-family:Arial, sans-serif;font-size:14px;font-weight:normal;padding:7px 5px;border-style:solid;border-width:1px;overflow:hidden;word-break:normal;border-color:black;}\n.tg .tg-lboi{border-color:inherit;text-align:left;vertical-align:middle}\n.tg .tg-9wq8{border-color:inherit;text-align:center;vertical-align:middle}\n.tg .tg-c3ow{border-color:inherit;text-align:center;vertical-align:top}\n.tg .tg-72fj{font-weight:bold;font-size:16px;border-color:inherit;text-align:center;vertical-align:middle}\n.tg .tg-0pky{border-color:inherit;text-align:left;vertical-align:top}\n--\u003e\u003c\/style\u003e\n\u003ctable class=\"tg\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth class=\"tg-72fj\"\u003eModel\u003c\/th\u003e\n\u003cth class=\"tg-72fj\"\u003eBTpro40\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"tg-lboi\"\u003eFree Air Displacement@60Hz,\u003cbr\u003elpm(CFM)\u003c\/td\u003e\n\u003ctd class=\"tg-9wq8\"\u003e40(1.4)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"tg-lboi\"\u003eUltimate Vacuum Pressure, Torr\u003c\/td\u003e\n\u003ctd class=\"tg-9wq8\"\u003e15\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"tg-lboi\"\u003eMaximum Vacuum, in.
