The AirTAC GFR600C20AJNTK AirTAC Filter Regulator NPT3/4 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 GFR600C20AJNTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size-600 unit has a 3/4 in NPT port, a 40 um standard filter element and an automatic drain that expels collected condensate without manual attention. The aluminium alloy bowl suits the larger 600 frame, and the fitted reverse/check valve holds the downstream setting if upstream supply is interrupted. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). No gauge is fitted on this configuration.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include manual or differential-pressure drains, a 5 um element (code W), gauge and scale choices, G or NPT threads in place of the PT standard, and a mounting bracket. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details 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.

Feeds filtered, regulated air to the tool-clamp and pallet-change circuits of a CNC machining centre, with the automatic drain keeping condensate out of the valves between shifts.
Conditions the air feeding cylinder-driven case packers and sealing heads on a packaging line, holding a steady downstream pressure so pick-and-place strokes stay consistent.
Serves as the main air drop at an assembly cell, filtering shop air before it reaches impact drivers and pneumatic presses while the check valve holds the set pressure through supply dips.
Size 600 with a 3/4 in NPT port is the right step when your line's flow demand sits above what a 400-size unit carries; match the port step to your piping rather than oversizing the regulator. The automatic drain on this unit suits unattended or hard-to-reach installations; choose manual drain where you prefer controlled blowdown, or differential-pressure drain for the default behaviour. The 40 um element is the standard grade for general plant air; specify the 5 um W-code element where downstream equipment needs finer filtration.
This configuration ships with no gauge and no mounting bracket, and the fitted K-code check valve protects the downstream setting. PT is the standard thread across the series, with G (BSPP) and NPT available as order options - this unit is specified in NPT. Because flow is published as curves rather than 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. 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 curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow curve and sizing from the datasheet on request.
The N code in GFR600C20AJNTK means no gauge is fitted on this configuration. GFR units can be ordered with an embedded square gauge or an external round gauge in MPa, psi or bar scales - ask us about a gauge-equipped variant if you need a local outlet-pressure readout.
