The AirTAC GFR60020ALF2GK AirTAC Filter Regulator G3/4 Low-Pressure 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 PT3/4" 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 GFR60020ALF2GK is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 configuration carries a G3/4 port, an automatic drain that clears collected condensate from the bowl without manual attention, a standard 40 um filter element, and a low-pressure regulator type. It is fitted with an embedded square gauge reading in psi and a reverse/check valve, and the aluminium alloy bowl suits this largest size in the range. A mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR line spans sizes 200 to 600 with port sizes from 1/8 to 1 inch, drain choices (differential-pressure, automatic or manual), an optional 5 um element (code W), gauge scale options in MPa, psi or bar, and PT, G or NPT threads. Because flow is published as curves rather than a single rating, we confirm the datasheet and flow 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.

Installed at the point where the main header feeds a packaging hall, this unit filters water and scale out of the supply and holds a reduced, low-pressure setting for the downstream actuators, with the automatic drain keeping the aluminium bowl clear during long shifts.
Feeding blow-off nozzles along a conveyor line, the 40 um element protects the nozzles from particulate while the regulator holds the steady low pressure the nozzles need, and the check valve prevents backflow into the drop.
On a laboratory automation skid that runs pneumatic grippers at reduced pressure, this filter regulator conditions the bench supply, and the square psi gauge gives operators a direct local reading of the set pressure.
Size 600 with a G3/4 port is the largest step in the GFR range; size up or down (200/300/400/600) against the flow your line needs, since larger sizes move more air at lower pressure drop. This unit pairs an automatic drain with a 40 um element - choose the manual-drain variant for periodic attention or the 5 um W element where finer filtration is required. The square gauge here reads in psi; MPa or bar scales are available, and an external round gauge is optional. The G thread is the order option fitted on this code; PT is the standard thread and NPT is also available. A bracket is included, and the low-pressure regulator type suits circuits that run below standard working pressures.
Flow for this family is published as curves, not a single rated figure, so ask us to confirm sizing against your application and the datasheet before ordering.
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 no single flow number can be quoted for this model. Tell us your line pressure and the flow your application needs, and we will confirm the sizing against the datasheet curves on request before you order.
The A in the code GFR60020ALF2GK specifies an automatic drain, which discharges collected condensate from the bowl without operator attention. The GFR family also offers a manual drain and a differential-pressure drain as order options, so you can match the drain to how the unit is accessed in your installation.
