The AirTAC GFR60025ALF2WGK AirTAC Filter Regulator G1 5 um 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 automatic 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 AirTAC GFR60025ALF2WGK is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This size 600 unit is built around a G1 (1 in) port with G thread, carries a 5 um filter element (code W, versus the 40 um standard), and drains condensate automatically, so the bowl empties itself during operation without manual attention. It is the low-pressure type (code L) for circuits regulated well below standard line pressure, and the fitted square gauge reads in psi. A reverse/check valve (code K) is fitted, and the 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, drain choices of differential-pressure, automatic or manual, 40 um or 5 um elements, standard or low-pressure regulation, and MPa, psi or bar gauge scales. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. 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.

| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |

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.

Point-of-use conditioning for a packaging machine section that runs actuators at low regulated pressure: the 5 um element keeps water and debris out of the valves while the low-pressure regulator holds the circuit at its setpoint, with automatic drain keeping the aluminium bowl clear.
Feeding low-pressure spray or coating equipment from a 1 in plant air main: the filter stage protects the gun and regulator seat from particulate and water, and the psi gauge lets operators verify and adjust the low regulated pressure directly at the booth.
Conditioning air for conveyor-mounted blow-off nozzles and low-pressure clamping cylinders: the automatic drain handles condensate from a humid main, the check valve holds the regulated circuit if upstream supply dips, and the included bracket fixes the unit to the machine frame.
Size 600 with a G1 (1 in) G-thread port is the largest step in the GFR range; step down to sizes 200-400 where the application draws less air. This unit already carries the 5 um element (W) and automatic drain (A); the alternatives are the 40 um standard element and differential-pressure or manual drains. Regulation here is the low-pressure type (L), intended for circuits held well below standard line pressure - confirm the exact range against your setpoint with us. The square gauge is scaled in psi; MPa and bar scales and an external round gauge are the other options. G thread is the fitted option; PT is the catalogue standard and NPT is also orderable. A bracket is included.
Flow for this family is published as curves, not a single rated number, so send us your flow and pressure requirements and we will confirm sizing from 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 flow for the GFR series as curves rather than a single rated figure, so we do not quote a rated flow number. Send us your required flow and working pressures and we will confirm the sizing from the datasheet on request.
The A in the code GFR60025ALF2WGK selects the automatic drain, which expels collected condensate during operation instead of waiting for a manual or differential-pressure drain - useful where the unit is not checked daily. The W selects the 5 um element instead of the 40 um standard, for finer particulate removal. Both are decodable options, and the 40 um element or other drain types can be ordered as separate model codes.
