The newly designed vacuum pumps operate 10C degrees cooler than other direct drive oil sealed vacuum pumps, which means less reaction to the oil from contaminants and less oil consumption. The lower operating temperature keeps the oil more viscous, limiting oil mist from the exhaust.\u003c\/p\u003e\n\u003cp\u003eThe CRV Pro line of pumps have a PTFE lined oil case and black oxide coated module for increased chemical resistance. The larger oil capacity to pumping speed dilutes contaminants to keep better oil quality for longer intervals.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"http:\/\/docs.chemtechscientific.com\/CRVpro%20brochure.pdf\"\u003eCRVpro brochure.pdf (chemtechscientific.com)\u003c\/a\u003e\u003c\/p\u003e\n\u003ctable width=\"520\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"238\"\u003eWhat's included\u003c\/td\u003e\n\u003ctd width=\"282\"\u003e2 liters Welch Premium oil, Cat# 8995P-11, NW 16 inlet and exhaust fitting with 5\/8” – 3\/4” hose barb for intake and NW 16 hinged clamp with centering ring.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon accessory, not included\u003c\/td\u003e\n\u003ctd\u003eExhaust filter cat# 700010\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePumping Speed\u003c\/td\u003e\n\u003ctd\u003e4.2 CFM (118 l\/min)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax.
