The AirTAC GFR600C25ALF2TK AirTAC Filter Regulator 1 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 GFR600C25ALF2TK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This 600-size unit is threaded 1 in NPT, carries the standard 40 um filter element, and has an automatic drain that discharges collected condensate without operator attention. It is the low-pressure regulator type, is fitted with an embedded square gauge reading in psi, and includes a reverse (check) valve and a mounting bracket. The 600-size bowl is aluminium alloy, and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, in PT, G (BSPP) or NPT thread, with differential-pressure, automatic or manual drains, a 40 um standard or 5 um (code W) element, gauge and scale options, and an optional reverse valve. 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.

Point-of-use conditioning ahead of pneumatic nutrunners and clamp cylinders on a car trim line: the filter stage strips water and pipe scale, and the low-pressure regulator holds the tools' supply at the line's set working pressure.
Conditioning the air feeding stop gates, diverters and pusher cylinders on a bottling conveyor, where the automatic drain clears condensate through continuous shifts without an operator visiting each drop.
Supplying clean, regulated pilot air to actuated ball and butterfly valves on a water-treatment skid, with the fitted reverse (check) valve part of the pilot circuit and the psi gauge giving operators a local setpoint readout.
Size the unit by port and flow: the 600 size is the largest step in the GFR range and this model carries a 1 in NPT port, so step down to 300 or 400 if your circuit draws lighter flow. Choose the drain to match maintenance practice: this model's automatic drain (code A) suits unattended duty, while manual and differential-pressure drains are orderable alternatives. The standard 40 um element covers general air prep; specify the 5 um (W) element where finer filtration is needed. The embedded square gauge here reads in psi, with MPa or bar scales and an external round gauge available. PT is the standard thread; G (BSPP) and NPT are catalogue options ordered by suffix, as with the T in this code. A bracket is included on this model.
One honest note on sizing: AirTAC publishes flow for these units as curves, not a single rated number, so we do not quote a figure here. Send us your required flow and pressure and we will confirm against the datasheet before you order. The low-pressure regulator type on this model is also a decodable choice - confirm its adjustment range with us for your setpoint.
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 GFR units as curves, not as a single rated figure, so we do not quote a number here. Send us your application flow and working pressure and we will confirm from the AirTAC datasheet whether the 600 size with a 1 in NPT port is correctly sized before you order.
This unit carries drain code A, the automatic drain, which discharges condensate from the bowl without operator attention - useful on unattended or continuous-duty installations. GFR filter regulators can also be ordered with a manual drain or with the default differential-pressure drain. On standard-type units the regulator adjustment range differs by drain type; this model is the low-pressure type, whose exact range is not published in our sheet, so we confirm it on request.
