The AirTAC GFR60025MJC3WT AirTAC Filter Regulator 1 in NPT 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR60025MJC3WT is an AirTAC GFR600 filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This configuration is the size 600 unit with a 1 in NPT port, a 5 um filter element (the finer of the two catalogue grades), a manual drain for the bowl, a round external gauge scaled in bar, and no mounting bracket. The maximum working pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the operating temperature range is -5 to 70 C, non-freezing. Because this is the 600 size, 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, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um elements, embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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 0.05 - 0.9 MPa (7 - 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". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 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. |
| W | Filtering grade 5 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.

Installed at the 1 in main drop feeding a CNC machining cell, this unit removes water and particles from the shop air and holds a set downstream pressure for the cell's valves and actuators, with the bar-scaled gauge giving the operator a local pressure reading.
Mounted ahead of the manifold on a carton-forming and sealing conveyor line, the 5 um element protects directional valves and cylinders from particulate carryover while the regulator keeps actuator speed consistent as upstream pressure fluctuates.
Used on a test bench where large-bore cylinders and valves are cycled at controlled pressures, the filter regulator supplies clean, regulated air through the 1 in NPT connection, and the manual drain lets the technician clear accumulated condensate between test runs.
Size 600 with a 1 in port is the largest step in the GFR range, so the first selection decision is whether your line flow justifies the 600 frame or whether a 200/300/400 unit on a smaller port is the better match. This unit is ordered with the 5 um element rather than the 40 um standard, which suits air that feeds sensitive downstream equipment; the manual drain means an operator opens the bowl drain periodically instead of relying on an automatic or differential-pressure drain. The round gauge fitted here is scaled in bar; square embedded gauges and MPa or psi scales are alternatives in the family. PT is the standard thread and G or NPT are catalogue options - this code is the NPT version. No mounting bracket is included with this code. 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 figure, so we do not quote a rated flow, Cv or SCFM number for this unit. Tell us your line pressure, downstream pressure setpoint and expected air demand, and we will confirm the sizing from the datasheet on request before you order.
The M in the code selects the manual drain option. Condensate collected in the aluminium alloy bowl must be drained by opening the drain by hand at intervals, rather than being discharged automatically as with the automatic or differential-pressure drain options. If nobody is at the machine regularly, ask us about the automatic-drain variant of the same GFR600 unit.
