The AirTAC GFR600-25 AirTAC Filter Regulator 1 in PT, 5 um is a genuine G-series filter regulator: water separation, 5 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 GFR600-25 is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This size-600 unit is specified with a 1 inch PT port, a 5 um filter element (the finer of the two grades offered), an automatic drain that expels collected condensate without manual attention, and an external round gauge reading in psi. The standard regulator adjusts outlet pressure across 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, and PT, G or NPT threads. At size 600 the bowl is aluminium alloy. Flow is published as curves rather than a single rated figure, 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.

| 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. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT 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.

Feeding filtered, regulated air to the clutch and counterbalance circuits of a mechanical stamping press, where the 1 inch port matches the main drop line and the 5 um element protects the valve stack.
Supplying large pneumatic cylinders on case-packing and palletising conveyors, with the automatic drain keeping condensate out of the actuators on a line that runs unattended.
Conditioning the supply to a quarter-turn pneumatic valve actuator on a process line, holding a steady set pressure so the actuator strokes consistently on every cycle.
Size 600 with a 1 inch PT port is the largest step in the GFR range, so start here when the line diameter and air demand point to the top of the series; smaller 200/300/400 units cover lighter duties. The 5 um element (code W) suits applications that need finer particulate removal than the 40 um standard; both grades are available across the family. Drain choice matters: automatic drain suits unattended duty, manual drain puts discharge in the operator's hands, and the differential-pressure default is also offered. The round psi gauge fitted here is the external option; an embedded square gauge with MPa, psi or bar scales is the alternative.
PT is the standard thread; G (BSPP) and NPT are order options. This configuration carries no mounting bracket (code J). Because flow is published as curves rather than a single rating, 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. Tell us your line conditions and required flow and we will confirm the datasheet curve values for the GFR600-25 on request before you order.
The automatic drain (code A) discharges collected condensate by itself, which suits units mounted in awkward positions or on equipment that runs without an operator nearby. Manual and differential-pressure drains are also available in the same size if you prefer to control discharge yourself.
