The AirTAC GFR600C20F1TK AirTAC Filter Regulator NPT 3/4 in 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 GFR600C20F1TK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is fitted with a 3/4 in NPT port, the standard 40 um filter element, a differential-pressure drain, an embedded square gauge with MPa scale, and a reverse (check) valve that holds the set pressure if the upstream supply is lost. The regulator is the standard type with 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 a mounting bracket is included.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in. Options across the family include automatic or manual drains, a 5 um filter element (code W), psi or bar gauge scales, an external round gauge, G (BSPP) or NPT threads, and low-pressure or no-bracket variants. Flow figures for this series are published as curves rather than a single rated number, so ask us and we will confirm the datasheet 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.

Installed at the drop to a CNC machining centre, this filter regulator cleans plant air of water and scale and holds a steady set pressure to the machine's pneumatic tool changers, clamps and solenoid valves. The check valve keeps the setting if the main supply dips.
Mounted ahead of the valve manifold on a packaging or bottling conveyor, this unit conditions the air feeding grippers, pushers and stopper cylinders, with the square MPa gauge giving operators a visible setpoint at the line.
Used as the conditioning and regulation point on a dedicated air drop feeding an automated assembly or robotic handling station, where the 40 um element protects directional valves and the regulator sets a stable working pressure for the whole station.
Size 600 with a 3/4 in NPT port is the largest step in the GFR range; step down to 400, 300 or 200 (down to 1/4 in and smaller ports) where your air consumption is lower. The differential-pressure drain on this unit bleeds accumulated condensate automatically whenever the pressure differential across the filter is high enough; if your line runs consistently at low differential, consider the automatic drain (code A) or manual drain (code M) variants instead. The standard 40 um element suits general plant air; specify the 5 um W-grade element where downstream valves and cylinders need finer filtration. The fitted square gauge reads in MPa; psi and bar scales are available, and an external round gauge is an option. PT is the standard thread for this series, with G (BSPP) and NPT as order options - this unit is the NPT version. A bracket is included; J-code variants omit it.
Because flow for the GFR series is published as curves and not as a single rated figure, please 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 rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your application and operating pressure and we will confirm the relevant datasheet flow figures for this size 600, 3/4 in unit on request.
This unit's differential-pressure drain discharges collected condensate automatically when the pressure drop across the filter element rises enough - no manual attention in normal service. If your line runs at a consistently low pressure differential, or you prefer to drain on a fixed schedule, the automatic drain (code A) or manual drain (code M) variants of the same GFR600 unit are the alternatives.
