The AirTAC GFR600-25AJC1T AirTAC Filter Regulator, NPT1, Auto Drain 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 GFR600-25AJC1T is a size-600 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 1 in NPT port, an automatic drain that expels collected condensate without manual attention, a standard 40 um filter element, and a round pressure gauge with MPa scale. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). The size-600 bowl is aluminium alloy, and no mounting bracket is included in this code.
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, a choice of differential-pressure, automatic or manual drain, a 5 um (code W) filter element option, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so we 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. |

| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 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 drop from a large plant air main to condition and regulate the supply feeding a production department, with the automatic drain handling condensate carryover without daily attention.
Placed upstream of the valve manifold on a palletising or packaging conveyor line, filtering water and debris from the header air and holding a stable set pressure to the cylinder circuit.
Fitted in a maintenance bay or on heavy-vehicle test rigs where 1 in NPT tooling and actuation circuits need filtered, regulated air from the shop compressor system.
Size 600 with a 1 in NPT port is the largest step in the GFR range, so size it where your line's required flow is highest; the smaller 200/300/400 sizes use smaller ports and lower flow capacity. The automatic drain suits unattended duty; choose manual drain where you prefer scheduled draining, or the differential-pressure default where draining on a pressure drop is acceptable. The standard 40 um element covers general air preparation; specify the 5 um W-code element where finer filtration is needed. This unit carries a round MPa gauge; square gauges and psi or bar scales are alternatives, and PT or G threads can be ordered instead of NPT. Flow is published as curves, not a single rating, so 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, not as a single rated number, so we do not quote a figure here. Ask us and we will confirm the datasheet flow curve for the GFR600 at your operating conditions before you order.
The A in the code GFR60025AJC1T specifies an automatic drain, which expels collected condensate from the aluminium alloy bowl on its own. Differential-pressure (blank) and manual (M) drain versions are available in the same size if you prefer a different draining method.
