The AirTAC GFR600C25C1TK AirTAC Filter Regulator NPT1 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 GFR600C25C1TK is a size-600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body, with a 1 in NPT port for main-line air supply. This configuration carries the standard 40 um filter element, a differential-pressure drain that bleeds collected condensate automatically whenever the pressure drop across the element rises, a round pressure gauge scaled in MPa, and a built-in reverse (check) valve that holds downstream settings when upstream supply is lost. The regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the aluminium alloy bowl suits the large 600-size body. Operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, in PT (standard), G (BSPP) or NPT thread, with manual, automatic or differential-pressure drains, 40 um or 5 um (W) filtration, square or round gauges scaled in MPa, psi or bar, and optional check valves. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

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 take-off point of a factory compressed-air ring main, the 1 in NPT port and 600-size body condition the supply feeding an entire production bay, removing pipe-scale particles and condensed water while holding a set line pressure.
Feeding the air supply of a CNC machining centre, the unit filters water and swarf-laden particulate from the shop air and regulates it to the pressure the machine's pneumatic tool-changer and clamping circuits were designed for.
On a bottling or canning line, the regulator sets a stable pressure for the conveyor stop-gates, pushers and grip cylinders, while the 40 um element and differential-pressure drain keep condensate out of the valves along the line.
Start with the port and size: this unit is the 600 size with a 1 in NPT thread, the largest step in the GFR range, so match it to your main-line pipe and the flow your downstream actuators need - we can confirm sizing from the published flow curves before you order. Choose the drain to suit access: this unit uses the differential-pressure drain (no operator attention between element-load events); automatic (A) and manual (M) drains are orderable alternatives. Filtration is 40 um as coded; specify W for 5 um where finer pre-filtration is required. The gauge here is the external round type scaled in MPa; square embedded gauges and psi or bar scales are options. Thread is NPT as coded, with PT (standard) and G also available, and the mounting bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated figure, so we do not quote a flow number here. Tell us your line pressure and air demand and we will confirm the correct size and regulation range from the datasheet on request.
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 family as curves rather than a single rated figure, so no flow number is stated here. Contact us with your line pressure and air demand and we will confirm the sizing from the datasheet on request.
The coded drain is differential-pressure: condensate collected in the aluminium bowl is discharged automatically when the pressure drop across the 40 um element rises, with no operator attention. If you prefer an automatic (A) or manual (M) drain, that is an orderable alternative in the same series.
