The AirTAC GFR600C25LF1TK 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 AirTAC GFR600C25LF1TK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a 1 in NPT port, the standard 40 um filter element, a differential-pressure drain, and the low-pressure regulator type. It ships as coded with an embedded square gauge reading in MPa, a reverse/check valve fitted, and a mounting bracket included. The aluminium alloy bowl suits the largest frame in the G-series, with a maximum inlet pressure of 1.0 MPa (145 psi) and 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, and options including 5 um filtration (code W), automatic or manual drains, gauge scale choices, G (BSPP) or NPT threads in place of the PT standard, and reverse/check valves. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Conditioning the main air drop that feeds large pneumatic cylinders on a metal stamping press, where water and scale carried from the compressor must be knocked out before the line regulator sets working pressure.
Filtering and regulating the supply ahead of the valve manifold on a cartoning or case-packing line, keeping condensate and pipe debris out of the directional valves while holding a stable set pressure.
Supplying a filtered, regulated air feed to the clamping circuit of a CNC machining centre, where the low-pressure regulator type sets a controlled clamp pressure and the check valve holds the line against backflow.
Start with the port step: this unit is the 1 in NPT size 600 frame, the largest in the GFR range, so step down to a 300 or 400 if your supply line is smaller. Choose the drain to match access: differential-pressure (as coded here) drains automatically as pressure drops, automatic (A) drains continuously, and manual (M) needs a periodic bowl purge. The 40 um element as coded is the standard grade; specify W for the 5 um option where finer filtration is needed. The embedded square MPa gauge is fitted as coded, and an external round gauge with MPa, psi or bar scales is available. PT is the standard thread; G (BSPP) and NPT are catalogue options to order. Bracket included as coded; J omits it.
Be aware this is the low-pressure regulator type, so confirm the set-pressure window suits your circuit before ordering - we will confirm the exact regulation range from the datasheet on request. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing against the 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a l/min or SCFM number. Send us your line size and application and we will confirm the flow curve and datasheet figures for this 1 in size 600 unit on request before you order.
The L in the code marks the low-pressure regulator type rather than the standard one, for circuits that work at reduced set pressures. Because the exact regulation window for this type is not published in the standard tables, confirm your set pressure with us and we will verify it against the datasheet. The rest of the decode is standard: 1 in NPT port, 40 um element, differential-pressure drain, square MPa gauge, reverse/check valve fitted, bracket included.
