The AirTAC GFR600C20AJF2T AirTAC Filter Regulator NPT3/4, Auto 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 See datasheet ports, a differential-pressure 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 GFR600C20AJF2T is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 3/4 in NPT port, an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, and an embedded square gauge reading in psi. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy, and this unit is ordered without a mounting bracket and without a reverse/check valve.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of drain type (differential-pressure, automatic or manual), filter grade (40 um standard or 5 um with code W), gauge scale (MPa, psi or bar), thread (PT standard, with G and NPT as order options) and bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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 plant air main to feed assembly stations, this unit strips water and scale from the supply and holds a set working pressure for air tools and clamping fixtures, with the automatic drain handling condensate on an unattended line.
On a bottling or cartoning conveyor, the 40 um element protects directional valves and cylinders from particulate and moisture while the regulator holds a stable pressure so pick-and-place and clamp sequences repeat consistently shift after shift.
Feeding a machining centre's pneumatic panel from a 3/4 in supply, the unit filters the incoming air and sets the pressure the machine builder specifies, with the psi square gauge giving the maintenance team a direct local reading at the machine.
Start with the port step: this unit is size 600 with a 3/4 in NPT port, the largest in the GFR range, which suits lines with higher air demand - match the size to the flow your circuit needs rather than to the pipe alone. Choose the drain to match access: automatic (as here) drains unattended, manual suits attended installations, and the differential-pressure default drains on a pressure drop. Filter grade is 40 um standard; specify code W for the 5 um element where downstream equipment needs finer filtration. Gauge scale is selectable (MPa, psi or bar) - this unit carries the square gauge in psi, with an external round gauge available as an option. Thread is PT as standard with G (BSPP) and NPT as order options, and the bracket is optional (this unit is code J, no bracket).
One honest note before ordering: AirTAC publishes flow for this family as curves, not as a single rated number, so we cannot quote a rated flow figure 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 flow for the GFR series as performance curves rather than a single rated figure, so we do not state a rated flow, Cv or SCFM number. Tell us your application and operating pressure and we will confirm the flow from the datasheet curves on request before you order.
The A in the code GFR600C20AJF2T specifies an automatic drain, which ejects collected condensate from the aluminium alloy bowl without anyone opening it - useful for inaccessible or continuously running installations. The GFR family is also available with a manual drain or with the differential-pressure drain as the default, and with a 5 um element (code W) instead of the 40 um standard fitted here.
