The AirTAC GFR60020LJC1WTK AirTAC Filter Regulator 3/4 in NPT 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 PT3/4" ports, a differential-pressure 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 GFR60020LJC1WTK is an AirTAC GFR600 filter regulator: filtration and pressure regulation combined in a single body, so one unit removes water and particulate from compressed air and holds a set downstream pressure. This configuration is the size 600 unit with a 3/4 in NPT port, the 5 um filter element (code W, in place of the 40 um standard), a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential is sufficient, and the low-pressure (L) regulator type for applications set below the standard range. It carries a round external pressure gauge scaled in MPa and a built-in reverse/check valve, and it is supplied without a mounting bracket. The size 600 bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and can be ordered with a 40 um or 5 um element, differential-pressure, automatic or manual drain, standard or low-pressure regulation, a square or round gauge with MPa, psi or bar scale, a reverse/check valve, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the flow and 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". |
| (blank) | Drain: Differential-pressure 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). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 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.

At the supply drop feeding a spray booth's air knife and gun actuators, this 3/4 in filter regulator strips water and fine particulate and holds the low set pressure the booth controls expect, with the MPa gauge giving operators a visible setpoint.
On a bottling hall conveyor section driven by pneumatic pushers and stopper cylinders, the unit filters the plant air to 5 um and regulates it to the low working pressure the actuators are set for, while the check valve holds the circuit if supply dips.
Ahead of a bank of directional control valves on a process skid, the filter regulator conditions the 3/4 in header air - removing condensate and 5 um particles and holding a stable low pressure - so the valve spools are not fed dirty or over-pressure air.
Start with the port step: this unit is size 600 with a 3/4 in NPT port, the largest in the GFR range, so it suits lines where a smaller 1/2 in or 3/8 in body would restrict the circuit. Choose the drain to match maintenance access: differential-pressure (this unit) needs no daily attention, automatic drains continuously, and manual drain suits attended installations. Choose the 5 um element (this unit) where downstream valves and actuators need finer filtration than the 40 um standard, and pick the gauge scale - MPa here, with psi or bar available. Thread is NPT on this code; PT and G are catalogue alternatives, and a mounting bracket can be added on other codes (this one ships without one). Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing against 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, not as a single rated number, so we do not quote a flow figure. Send us your line pressure, set pressure and expected air demand, and we will confirm the flow from the datasheet curve for this 3/4 in size 600 unit before you order.
L marks the low-pressure regulator type, for applications set below the standard range. The exact adjustment range for the low-pressure type is not published in our current data, so we confirm it on request. Note that the drain on this unit is differential-pressure, which is why the standard-range split between differential and manual drain does not apply here.
