The AirTAC GFR60020MJF2G AirTAC Filter Regulator G3/4, Manual Drain is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/4" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600-20G is a filter regulator: one body that first removes water and particulate from compressed air, then regulates downstream pressure. This configuration is the size 600 unit with a G3/4 (BSPP) port, a 40 um standard filter element, a manual drain bowl, and an embedded square gauge reading in psi. The regulation range is 0.05-0.9 MPa (7-130 psi) with this manual-drain version, and maximum inlet pressure is 1.0 MPa (145 psi). At size 600 the bowl is aluminium alloy, and operating temperature is -5 to 70 C (non-freezing). No mounting bracket is fitted and no reverse/check valve is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options include a 5 um element (code W), automatic or differential-pressure drain, alternative gauge scales (MPa/psi/bar), and PT, G or NPT thread. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Installed at the drop feeding a CNC machining centre, the unit cleans condensed water and swarf-laden particulate out of the shop air and holds a steady regulated pressure to the machine's pneumatic clamps and tool changers. The 3/4 in port suits a main branch line feeding the cell.
Mounted on the air drop serving a carton-forming and sealing conveyor, the filter stage protects directional valves and cylinders from water and dirt, while the regulator keeps actuator pressure consistent so case-ejection strokes stay repeatable through the shift.
Placed ahead of lab automation and sample-handling pneumatic circuits, the unit delivers filtered, regulated air to grippers and valves. The psi-reading square gauge gives operators a direct local pressure reference, and the manual drain suits a supervised environment where daily checks are routine.
Size and port are the first decision: 200/300/400/600 step up in port and flow capacity, and this is the largest, with a G3/4 port - match it to your line size and required flow. Drain type matters: manual drain (this unit) needs someone to open the drain periodically, while automatic drain handles condensate unattended and differential-pressure drain suits setups where the pressure drop across the element triggers draining. Filter grade is 40 um standard here; choose the 5 um W option when downstream equipment needs finer filtration. The gauge is the embedded square type reading psi; MPa or bar scales and an external round gauge are alternatives. Thread is G (BSPP) on this model - PT is the catalogue standard and NPT is available to order. Brackets are optional; this unit ships without one.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so we cannot quote a rated flow here. Send us your application details and we will confirm the datasheet figures before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR family as performance curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number here. Send us your line size and application and we will confirm the datasheet flow figures for this 3/4 in size 600 unit on request before you order.
This GFR600-20G carries code M, meaning the condensate bowl has a manual drain: an operator opens it periodically to discharge collected water. If the unit will be mounted where nobody drains it routinely, the automatic-drain option (code A) discharges condensate by itself, and the differential-pressure drain (the default, no code) is the third choice. Note the manual-drain version also has the wider 0.05-0.9 MPa (7-130 psi) regulation range.
