The AirTAC GFR60020LJF3WTK AirTAC Filter Regulator NPT3/4, 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 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 AirTAC GFR60020LJF3WTK 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 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and a low-pressure regulator type for circuits set below standard working ranges. It ships as coded with a square embedded gauge reading in bar, a reverse/check valve fitted, an aluminium alloy bowl, and no mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans sizes 200 to 600 with port sizes from 1/8 in to 1 in. Options across the series include 40 um or 5 um filtration, differential-pressure, automatic or manual drains, square or round gauges with MPa, psi or bar scales, and G, NPT or PT threads. Published flow data appears as curves rather than a single rating, so ask us to confirm the 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). |
| F | Gauge shape: Square. C is round, F is square. |
| 3 | Gauge scale: bar. 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.

Feeds the pneumatic clamps and swing cylinders on a vehicle assembly line, filtering machining moisture and fines to 5 um while holding a low set pressure suited to light clamping force requirements.
Supplies the seal jaws, tray pushers and vacuum-assist circuits of a packaging line, where the 5 um element protects small pilot valves and the check valve holds downstream pressure if upstream supply dips.
Conditions the air feeding loom air-jets and doffing arms, where the low-pressure regulator type matches the modest set pressures these stations run at and the 3/4 in port serves the machine's main drop.
Start with the port and size step: this unit is size 600 with a 3/4 in NPT port, the largest step in the GFR range, so match it to the pipe size and air demand of your circuit. Choose the drain type where it applies: differential-pressure (as coded here) suits lines with steady flow, automatic drain suits intermittent or unattended duty, and manual drain suits periodically attended points. Choose the filter grade: 40 um is the standard element, while the 5 um element coded here (W) protects downstream components that are sensitive to finer particles. Gauge scale (MPa, psi or bar), thread type (PT standard, G or NPT to order) and bracket inclusion are all decodable choices. Because flow is published as curves rather than a single rating, 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 flow for this series as curves, not as a single rated figure, so we do not quote a l/min or SCFM number. Send us your line pressure, set pressure and expected air demand, and we will confirm the flow figures from the datasheet against your application before you order.
W selects the 5 um filter element instead of the 40 um standard, for finer protection of downstream valves and cylinders. F3 selects the embedded square gauge with a bar scale; MPa or psi scales and an external round gauge are alternative order options on the same series.
