The AirTAC GFR600C20AF1T AirTAC Filter Regulator 3/4 in NPT 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 GFR600C20AF1T 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, a 40 um standard filtration element, an automatic drain that expels collected condensate without manual attention, an embedded square pressure gauge scaled in MPa, and a standard regulator with a 0.15-0.9 MPa (20-130 psi) adjustment range. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). The size 600 bowl is aluminium alloy, and a mounting bracket is included.
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, a choice of PT (standard), G or NPT thread, manual, automatic or differential-pressure drains, 40 um or 5 um (W) filtration, gauge and scale options, and a low-pressure type. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and 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 0.15 - 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.

Clean, regulated air at each 3/4 in drop feeding impact tools and pneumatic clamps along the final line, with automatic drain keeping condensate off the tools between shifts.
Stable regulated pressure to carton sealers and case erectors on a high-throughput packaging line, where the 40 um element protects valve spools from pipe-scale and rust particles.
Point-of-use filtration and regulation ahead of tool-changer and clamp cylinders on a machining centre, with the MPa square gauge giving the operator a direct set-pressure readout.
Size 600 with a 3/4 in NPT port sits at the top of the GFR range; step up or down through sizes 200, 300 and 400 to match the port size and flow demand of your circuit. The automatic drain on this unit suits installations that are not attended daily; choose manual drain where you prefer controlled blow-down, or the differential-pressure drain default. The 40 um element is the standard grade; specify the W code for the 5 um grade if downstream equipment needs finer filtration. The embedded square gauge here reads in MPa, and psi or bar scales plus an external round gauge are order options. PT is the standard thread; G and NPT are catalogue options ordered by suffix, as on this T-code unit, and a bracket is included.
Flow for this family is published as curves, not a single rated number, so we cannot quote a rated flow figure. 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, not as a single rated figure, so we do not quote a rated flow number for this unit. Send us your application flow and pressure requirements and we will confirm sizing against the datasheet curves on request before you order.
The A in the model code specifies an automatic drain, which expels collected condensate from the bowl without operator attention - useful on lines that run unattended. The GFR family is also ordered with a manual drain or the differential-pressure drain default, so a differently suffixed GFR600 covers those choices.
