The AirTAC GFR60025MLF2K AirTAC Filter Regulator 1 in PT 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 GFR60025MLF2K is a size-600 GFR filter regulator: water and particulate filtration plus pressure regulation in a single body. This configuration is built around a 1 inch PT port, a manual drain on the bowl, the standard 40 um filter element, and the L low-pressure regulator type. It ships as coded with a fitted reverse/check valve, an embedded square gauge reading in psi, and a mounting bracket. At size 600 the bowl is aluminium alloy, and the maximum working (inlet) pressure is 1.0 MPa (145 psi) with a working temperature range of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT as the standard thread and G (BSPP) or NPT as order options, a choice of differential-pressure, automatic or manual drain, a 5 um element (code W) where finer filtration is needed, gauge scale choices, and an optional reverse/check valve. Flow figures for this family are published as curves rather than a single rated number, 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |

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.

At the 1 in main drop feeding a stamping or forming press, this unit filters incoming compressed air and holds a steady, reduced supply pressure to the press valves, with the check valve holding the downstream circuit if upstream supply dips.
Mounted ahead of a large directional-valve manifold on a material-handling line, it removes water and pipe scale at the standard 40 um grade and lets maintenance set the manifold pressure from the psi gauge without pulling the line apart.
On a packaging or palletising conveyor run with air cylinders and diverters on a 1 in header, the low-pressure regulator type suits circuits running below standard line pressure, and the manual drain lets operators bleed accumulated condensate at shift checks.
Start with size and port: the 600 frame with its 1 in PT connection is the largest step in the GFR range, so match it against the pipe size and air demand of the line it will feed - we can confirm the flow curve against your requirement before you order. Next, choose the drain: this unit has a manual drain, which suits positions where an operator can bleed the bowl on a routine; automatic or differential-pressure drains are available on other codes in the series. The 40 um element fitted here is the standard grade; specify the W code if you need the 5 um option. The square gauge is set to the psi scale (MPa and bar scales are alternatives), and the low-pressure (L) regulator type is intended for circuits that run below standard line pressures - its exact regulation range is not published in the catalogue, so confirm it with us. Thread is PT as standard with G and NPT orderable; a bracket is included, and the fitted K check valve holds downstream pressure on upstream dropout.
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 family as curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your application's air demand and line pressure and we will confirm the datasheet flow curve for this exact 1 in, size-600 unit on request.
In the GFR code the M position selects the manual drain - an operator opens it to bleed the bowl, unlike the automatic (A) or differential-pressure (blank) options that discharge condensate without attention. The F2 position fits the embedded square gauge with the psi scale; MPa and bar scales are alternatives, and an external round gauge is optional.
