The AirTAC GFR600-25C1T AirTAC Filter Regulator 1 in NPT 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 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 GFR600-25C1T is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This 600-size unit is threaded 1 in NPT, uses the standard 40 um filter element, and handles condensate with the family's default differential-pressure drain. The standard-type regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), the maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). This configuration is fitted with an external round gauge reading in MPa; at size 600 the bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options include a 5 um element (code W), automatic or manual drains, square or round gauges with MPa, psi or bar scales, G (BSPP) or NPT threads in place of the PT standard, and bracketless versions. Flow is published as curves rather than a single rating, 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.

| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |

| 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. |

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.

Fit at the main drop leaving a plant compressor room to knock water and scale out of the supply and set a steady header pressure for the whole shop floor.
Mount ahead of the valve manifold feeding the cylinders on a packaging conveyor, so carton clamps and pushers receive a cleaned, regulated air supply.
Place upstream of the pneumatic clamps and tool-changer cylinders on a CNC machining cell, where clean, regulated air supports the workholding sequence.
Size and port are the first choice: 600 is the largest GFR frame and this unit takes a 1 in NPT port, so match it against the air demand of the line it will feed - we can check the published flow curves against your requirement on request. The other decodable choices are drain type (differential-pressure as here, automatic with code A, or manual with code M), filter grade (40 um standard, 5 um with code W), gauge scale (MPa on this model; psi or bar available), thread (PT is the AirTAC standard, with G and NPT as order options), and the mounting bracket, which is included on this model.
Note that the regulation range depends on the drain: with the differential-pressure or automatic drain it is 0.15-0.9 MPa (20-130 psi), while the manual-drain version widens the range down to 0.05 MPa (7 psi).
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 a single rated figure, so we do not quote a number here. Send us your line demand and we will confirm the sizing against the datasheet curves on request.
This model uses the differential-pressure drain, the default for the GFR family. If you prefer an automatic cycle or manual emptying, order the A (automatic) or M (manual) code variant; note that the manual-drain version also widens the regulation range down to 0.05 MPa (7 psi).
