The AirTAC AirTAC GFR60020ALJF2TK Filter Regulator, NPT3/4 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 GFR600-20AL is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 3/4 in NPT port, a 40 um standard filter element, an automatic drain that expels collected condensate without manual attention, and a low-pressure regulator type. An embedded square gauge graduated in psi is fitted, a reverse (check) valve is included, and no mounting bracket is supplied. Because this is the 600 size, the bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 in to 1 in, with drain choices (differential-pressure, automatic or manual), an optional 5 um element (code W), gauge scales in MPa, psi or bar, and G or NPT thread options beyond the PT standard. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

|---|---|
| 20 | Port size PT3/4". 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. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. 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. |
| 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.

Feeding filtered, regulated air to paint-line drops where coating work needs a low-pressure setting. The automatic drain clears condensate between shifts without an operator walking the line, and the 40 um element keeps pipe scale out of the spray circuit.
A 3/4 in NPT main feeding cylinders and actuators along a packaging conveyor. The 40 um element catches rust and debris from the header, the psi gauge gives operators a visible setpoint check, and the reverse valve helps hold the circuit at shutdown.
Conditioning the air supply to pneumatically actuated process valves on a skid or manifold. The aluminium alloy bowl suits the larger 600 frame, the automatic drain handles moisture at an unmanned panel, and the low-pressure regulator type matches actuator supply duties.
Step up or down through the GFR sizes (200/300/400/600) to match the port and flow path your line needs; this unit sits at the top of the range with a 3/4 in NPT port. Drain type is a real choice: automatic (as here) suits installations that are not walked daily, manual suits attended stations, and differential-pressure is the catalogue default. Element grade is 40 um standard or 5 um with code W if finer filtration is required. The embedded square gauge is standard and can be ordered in MPa, psi or bar scale; an external round gauge is optional. Thread is PT as the AirTAC standard, with G (BSPP) and NPT (as on this model) as order options, and a bracket can be added where none is supplied. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application 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 GFR flow as curves, not as a single rated figure, so we do not quote a number. Tell us your application and we will confirm the flow figures from the datasheet on request before you order.
This model carries code A, an automatic drain, so collected condensate is expelled without manual attention - useful for panels and drops that are not checked daily. The catalogue alternative is a manual drain (code M) or the differential-pressure default; all three are orderable choices on the GFR family.
