The auto drain port comes with 3/8 One-touch fitting (applicable to the AF30-A to AF40-A). Note 2) Drain guide is G1/8 (applicable to the AF20-A) and G1/4 (applicable to the AF30-A to AF40-A). Note 3) A bracket is not assembled and supplied loose at the time of shipment. Including 2 mounting screws. Note 4) When pressure is not applied, condensate which does not start the auto drain mechanism will be left in the bowl. Releasing the residual condensate before ending operations for the day is recommended. Note 5) If the compressor is small (0.75 kW, discharge flow is less than 100 L/min ANR ), air leakage from the drain cock may occur during start of operations. N.C. type is recommended. Note 6) Refer to Chemical data on page 32 for chemical resistance of the bowl. Note 7) Standard material (polycarbonate) Note 8) Without a valve function. Note 9) For thread type: NPT.
