The AirTAC GFR600-25T AirTAC Filter Regulator 1 in NPT, Bar Gauge 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 GFR600-25T is a filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at your set point. This size 600 unit is specified for 1 in NPT ports, carries a 40 um filter element, drains condensate automatically, and is fitted with an external round gauge scaled in bar. The standard regulator covers a 0.15-0.9 MPa (20-130 psi) setting range, with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing). The aluminium alloy bowl suits this large size, and no mounting bracket is included in this configuration.
This is a genuine AirTAC part. The GFR series is published in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, drain choices (differential-pressure, automatic or manual), an optional 5 um element (code W), gauge and scale options, and G or NPT thread variants. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 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. |
| 3 | Gauge scale: bar. 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. |
| (blank) | No reverse-flow valve (the default). |
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.

Supply filtered, pressure-regulated air to a stamping press cell's main drop, keeping clamp and counterbalance circuits on a stable set point while the automatic drain clears condensate from a high-volume line.
Feed the pneumatic actuators on a beverage plant palletizer with water- and particulate-free air at a fixed pressure, so gripper and pusher cylinders cycle consistently through long shifts.
Condition the shop-air feed entering a CNC machining center's pneumatic panel, protecting tool-change and clamping valves from moisture and debris while holding the pressure the machine controls expect.
Size 600 with a 1 in NPT port is the largest step in the GFR range, so start by matching the port and the flow curve to your line's air demand; we can confirm curve figures on request. For this family the real choices are: drain type (automatic here, versus manual or differential-pressure), filter grade (40 um standard, 5 um with code W), gauge style and scale (this unit has an external round gauge in bar; an embedded square gauge with MPa, psi or bar scales is also available), thread (PT is the standard; G and NPT are order options), and whether a bracket is wanted. A reverse/check valve can be specified if backflow protection is needed.
Because flow is published as curves and not a single rating, send us your application details and we will confirm sizing against the datasheet 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 number, so we do not quote a figure here. Send us your line's air demand and we will confirm the flow-curve figures from the datasheet for this 1 in NPT, size 600 unit before you order.
This unit is coded A for an automatic drain, which ejects collected condensate without anyone opening the bowl - useful on large, high-flow mains like this size 600 body. If you prefer manual or differential-pressure draining, that is a decodable option in the same series; note the regulator setting range differs by drain type, so tell us which you need and we will confirm the right code.
