Only nitrogen generators are recommended for supported configurations. ADDITIONAL INFORMATION With standard J size cylinders, the customer may get only 40 hours of usage at normal flow rates. The nitrogen tank/generator must be 2 meters or less from the detector, otherwise there is a risk of flooding the detector due to insufficient supply of nitrogen from the generator/tank. id67898, 2424, 2424B
