F&J Model DF-1 Portable Low Volume Air Sampler With Digital Flow Meter Freight Field-replaceable detector window for reducedGENERAL DESCRIPTION: The Model DF 1 portable air sampling system with a digital flowmeter is a low volume air sampler consisting of oilless, carbon vane vacuum pump, with a mechanical constant air flow regulator for use where a nearly constant air flow is desirable. The regulator holds a constant pressure drop across an in line orifice by varying the flow through a bypass valve into the pump. This system allows the pump to work at a minimum pressure
