The AirTAC GFR600C20ALNT AirTAC Filter Regulator NPT 3/4 Low-Pressure 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 GFR600C20ALNT is a size 600 filter regulator: water and particulate filtration plus pressure regulation combined in one body, with no lubricator. This configuration carries a 3/4 in NPT port, the standard 40 um filter element, and an automatic drain that expels collected condensate from the bowl without manual attention. The regulator is the low-pressure type, no gauge is fitted with this code, and a mounting bracket is included. At size 600 the bowl is aluminium alloy, and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C (non-freezing).
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, a choice of differential-pressure, automatic or manual drain, a 5 um element option (code W), gauge and thread options, and standard or low-pressure regulator types. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Point-of-use air preparation on a cartoning or wrapping machine: the 40 um element strips water and pipe scale before the machine's valves and cylinders, while the low-pressure regulator holds the supply at the pressure the machine was set up for.
Feeding stop gates, pushers and lift cylinders on a bottling or canning conveyor, where the automatic drain keeps condensate out of the actuators without an operator having to bleed the bowl each shift.
Regulated, filtered air at assembly-cell drops for impact wrenches, clamps and air-fed fixtures in a commercial-vehicle plant, with the 3/4 in port serving high-draw tool circuits on the main drop line.
Start with the port step: this unit is size 600 with a 3/4 in NPT port, the largest in the GFR range, so step down to sizes 200-400 if your line runs smaller ports. Drain choice matters in practice: automatic drain (this code) suits unmanned or hard-to-reach installations, manual drain suits attended points of use, and the default differential-pressure drain suits standard duty. The 40 um element is standard; specify code W for the 5 um grade where downstream equipment needs finer filtration. This code is the low-pressure regulator type and carries no gauge; gauge options with MPa, psi or bar scales can be ordered if you want a local pressure readout. Thread is NPT here, with PT (standard) and G (BSPP) available as order options, and a mounting bracket is included.
One honest note before you order: flow is published as curves, not a single rated number, so we cannot quote a rated flow figure for this unit. Send us your application details and we will confirm sizing against the datasheet curves before you commit.
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 rated flow, Cv or SCFM number for this unit. Tell us your application and required flow, and we will confirm the sizing against the datasheet curves on request before you order.
The automatic drain expels collected condensate from the bowl on its own, which suits unattended or hard-to-reach installations; manual and differential-pressure drain versions are available if you prefer. No gauge is fitted with this code, so there is no local pressure readout - gauge options with MPa, psi or bar scales can be ordered if you need one. The regulator in this code is the low-pressure type; ask us to confirm its adjustment range from the datasheet.
