The AirTAC GFR600-25AJC2T 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 PT1" ports, a automatic 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 GFR600-25AJC2T is a size-600 filter regulator: it removes water and particulate from compressed air and sets downstream pressure in one body, on a 1 in NPT port. This configuration carries the automatic drain, so collected condensate is discharged without manual attention, and the standard 40 um filter element. It is fitted with an external round gauge reading in psi, and the regulator is the standard type with a setting 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.
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 include manual or differential-pressure drains, a 5 um (code W) element, embedded square or external round gauges with MPa, psi or bar scales, G or NPT thread variants, a bracket, and a reverse/check valve. Published flow data appears as curves rather than a single rating, 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.

|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |

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 from a factory compressed-air ring main, it dries and filters the supply and holds a steady header pressure for the whole bay, with the automatic drain handling condensate at the point of use.
Feeding the air-assist and clamping circuits of CNC machining centres, it strips water and chips-carried particulate before the valves and keeps actuator pressure inside the set range shift after shift.
Mounted ahead of the valve manifold on a cartoning or case-packing conveyor line, it conditions the air to the pick-and-place and sealing cylinders and lets the line supervisor read and hold set pressure on the psi gauge.
Use the size/port step to match your line: size 600 on a 1 in port suits the largest branch flows in the GFR range, but because flow is published as curves rather than one rated figure, ask us to confirm sizing against your actual demand before ordering. This unit already fixes several choices: automatic drain (no daily manual blowing down), 40 um standard filtration (choose code W for 5 um where finer particle removal matters), standard regulator with 0.15-0.9 MPa (20-130 psi) setting, and a round psi gauge. Thread here is NPT; PT is the standard thread and G (BSPP) is also a catalogue option if your piping uses it. A mounting bracket is available on the family; this code specifies no bracket.
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 this series as performance curves rather than a single rated figure, so we do not quote a number. Tell us your line pressure and air demand and we will confirm the datasheet curve and correct sizing on request before you order.
The A in this code specifies the automatic drain, which discharges collected condensate without anyone opening the bowl - useful on unattended or high-humidity installations. Manual and differential-pressure drains are catalogue options in the same family if your maintenance routine prefers a scheduled manual blow-down.
