The AirTAC AirTAC GFR60025MC1TK Filter Regulator NPT1 in 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 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 AirTAC GFR600 is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in one body. This configuration is built for 1 in NPT ports, drains manually, and carries the standard 40 um filter element. The set pressure adjusts anywhere from 0.05 to 0.9 MPa (7-130 psi), a round pressure gauge on an MPa scale is fitted, and a reverse/check valve helps hold downstream pressure if the supply dips. The aluminium alloy bowl suits this size 600 frame, and the unit operates from -5 to 70 C (non-freezing) at up to 1.0 MPa (145 psi) inlet pressure.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 in, and options include automatic or differential-pressure drains, a 5 um element (code W), embedded square gauges with MPa, psi or bar scales, G (BSPP) or NPT threads, and a bracketless build. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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 0.05 - 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. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| 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. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Filtered, regulated air at a fixed setpoint feeding a CNC machining center and its pneumatic clamping circuits, with the check valve helping hold settings through supply dips.
Clean, regulated air feeding quarter-turn actuator positioners on a treatment plant valve manifold - filtration and regulation in one body, with no oil mist added downstream.
Stable pressure to case-packing and labeling cylinder circuits on a packaging conveyor line, with the 40 um element protecting directional valves and cylinder seals from water and debris.
Step through sizes 200, 300, 400 and 600 to match the flow your line needs - this size 600 unit takes a 1 in NPT port for high-flow mains. Choose the drain: manual (this unit, with the widest 0.05-0.9 MPa adjustment band), automatic for hands-off condensate removal, or differential-pressure as the default. The 40 um element is standard; specify 5 um (code W) for finer protection. Gauges come embedded square or external round, scaled in MPa, psi or bar - this unit carries a round MPa gauge. PT is the standard thread; G (BSPP) and NPT are catalogue options to order. A mounting bracket is included unless code J is specified. Because flow is published as curves, not a single rating, send us your flow and pressure requirements 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm the datasheet curve and correct sizing on request.
The M code fits a manual drain: an operator opens the bowl drain periodically to remove collected condensate. On this manual-drain configuration the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi). If you prefer hands-off condensate removal, automatic (A) and differential-pressure drain versions are available to order.
