The AirTAC GFR600-20 AirTAC Filter Regulator NPT3/4 Round PSI Gauge 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 automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600-20 is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration has a 3/4 in NPT port, a 40 um standard filter element, an automatic drain that ejects collected condensate without manual attention, and a fitted reverse/check valve that holds the downstream setting when upstream pressure is lost. The round external gauge is fitted and reads in psi, and the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi). Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Because this is the 600 size, the bowl is aluminium alloy rather than polycarbonate, and no mounting bracket is included (code J).
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and is orderable with manual, automatic or differential-pressure drains, a 5 um (W) element, G (BSPP) or NPT thread options, square or round gauges in MPa, psi or bar scales, and a reverse/check valve. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and flow figures for your application on request.

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 0.15 - 0.9 MPa (20 - 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.

Dropped from a 3/4 in shop-air ring main ahead of a spray-booth distribution manifold, it strips bulk water and pipe scale and holds a steady regulated header so booth regulators downstream start from a clean, stable supply.
Mounted at the take-off feeding conveyor stop-gate cylinders and pusher actuators on a bottling line, it removes condensate carried up from the compressor room and keeps the regulated pressure that gates and diverters repeat against.
Installed on the supply branch serving two-post and four-post vehicle lifts in a truck or bus workshop, it protects the lift control valves from water and debris and holds the working pressure the lift controls were set up for.
Size 600 with a 3/4 in NPT port is the right step when your line's required flow sits at the top of the GFR range; step down to 300/400 if the demand is lighter, since port size and flow capacity rise together across the family. Drain choice is decodable: this unit has the automatic drain (code A), which suits unattended installations; manual drain (M) suits supervised points, and differential-pressure drain is the family default. The 40 um element fitted here is the standard grade; choose the 5 um W option where finer particulate protection matters. Gauge is the external round type reading psi (code C2); embedded square gauges and MPa or bar scales are the alternatives. Thread is NPT here, with G (BSPP) and PT as the other catalogue options, and this J-coded unit ships without a bracket. Because flow is published as curves and not a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR flow as performance curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your inlet pressure and the flow your application needs and we will confirm the sizing against the datasheet curves on request before you order.
The A in the code GFR60020AJC2TK selects the automatic drain, which discharges collected condensate from the aluminium bowl without anyone opening it - useful for unattended or high-humidity installations. The same GFR600 size is also orderable with a manual drain (M) or the differential-pressure drain, which is the family default.
