The AirTAC GFR600-20G 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: water and particulate removal plus downstream pressure regulation in a single body. This configuration is the size 600 unit with a G3/4 (BSPP) port, 40 um standard filtration, a manual drain bowl in aluminium alloy, a standard regulator with an adjustment range of 0.05-0.9 MPa (7-130 psi), an embedded square gauge reading in psi, and a mounting bracket included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of port, thread (PT standard; G and NPT as order options), drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um with code W), gauge scale and pressure type. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application.

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.

Mounted at the drop of a machine shop's air main, the GFR600-20G removes water and swarf-carrying particulate from the supply and holds a steady regulated pressure to the machine's pneumatic valves and actuators. The 3/4 in port suits a main feeding a full machining cell, and the psi gauge lets setters verify setpoint at a glance.
On a bottling or cartoning line, this unit conditions the air feeding conveyor stops, diverters and case-clamp cylinders. The manual drain bowl is emptied during scheduled changeover, the 40 um element protects downstream valves, and the regulator keeps clamp force consistent from the first shift to the last.
At a plant air take-off serving assembly stations, the GFR600-20G filters bulk water and pipe scale out of the compressed air and regulates pressure to air tools, clamps and small cylinders. The aluminium 600-size bowl and bracket allow straightforward panel or frame mounting next to the take-off point.
Size and port are the first decision: GFR comes in sizes 200, 300, 400 and 600, stepping up in port and flow capacity, so match the size to your line's air demand. Drain type is a real choice here: manual drain (this unit) needs periodic draining by hand, while automatic and differential-pressure drains handle condensate without operator attention. Filtration grade is 40 um standard; specify code W for 5 um where finer protection is needed. The embedded square gauge is standard with a choice of MPa, psi or bar scale (this unit reads psi), and an external round gauge is optional. Thread is PT as standard with G (BSPP) and NPT available to order; a bracket is included unless code J is specified.
Flow for this family is published as curves, not a single rating, so we cannot quote one number here. Send us your application details and we will confirm sizing against the datasheet curves 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 GFR flow as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number for this unit. Send us your application details and we will confirm the sizing against the datasheet curves on request before you order.
This GFR600-20G is ordered with code M, a manual drain: condensate collected in the bowl is emptied by hand at intervals you set. The family also offers automatic drain (code A) and the default differential-pressure drain if you want condensate handled without operator attention. Note that the manual-drain version carries the wider regulator adjustment range of 0.05-0.9 MPa (7-130 psi).
