2.15 Discharge Provisions Dryfast Vacuum Pump Models 2014, 2032, 2034, 2037, 2042 2044 and 2047 come with two hose barbs, one Intake and one Exhaust. All hose barbs and muffl ers are supplied loose with the pump. The hose barb used on all models accepts 3/8” I.D. hose. By threading the hose barb in the exhaust port of the pump, a vent line can be attached which allows gases and vapors pumped through the pump to be piped from the work area into a hood. -
