The AirTAC GFR60025MC2TK 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 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 combines filtration and pressure regulation in a single body: compressed air passes a 40 um element that strips water and particulate, then flows through the regulator that holds your set downstream pressure. This configuration is the size 600 unit with a 1 in NPT port, a manual drain for operator-controlled condensate bleeding, a round gauge reading in psi, a reverse/check valve fitted, and a mounting bracket included. The aluminium alloy bowl suits this large-frame size, maximum inlet pressure is 1.0 MPa (145 psi), and the standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi) with manual drain. Operating temperature is -5 to 70 C, non-freezing.
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 automatic or manual drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, G or NPT threads in place of the PT standard, and low-pressure regulator types. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the datasheet figures 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)). |

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 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.

Filter and regulate the main supply feeding fillers, cappers and actuator manifolds. The 1 in port suits a header take-off, and the manual drain lets the shift technician bleed accumulated condensate at start-up.
Condition the air going to clamping cylinders and fixture valves: the 40 um element keeps swarf-laden condensate out of the circuit while the regulator holds a steady clamp pressure, checked on the round psi gauge.
Supply impact wrenches, tire cages and inflation equipment from a shop compressor. The reverse/check valve holds downstream pressure if the supply dips, and the psi gauge gives technicians a visible setpoint.
Start with the port and size step: the GFR600 with its 1 in connection is the largest frame in the family, so size up from the 200/300/400 units when your line volume demands it - and let us confirm the flow curve against your consumption before you order, since AirTAC publishes flow as curves rather than one rated number. Choose the drain to match maintenance habits: manual (this unit) means an operator opens the drain at intervals, automatic bleeds continuously, and the differential-pressure default drains only when the pressure differential calls for it. The 40 um element on this unit is the standard grade; specify the W code if your application needs the 5 um option. This unit carries a round gauge on a psi scale; embedded square gauges and MPa or bar scales are available. Thread is NPT here - PT is the catalogue standard, with G and NPT as order options - and the bracket is included.
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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, set pressure and air consumption and we will confirm the datasheet flow curve for this 1 in unit on request.
The M in the code means the bowl drain is opened by hand, which suits installations an operator visits regularly. If the unit sits in an inaccessible spot or runs unattended, order the A code for an automatic drain. With this manual-drain configuration the regulator adjustment range is 0.05-0.9 MPa (7-130 psi).
