The AirTAC GFR60020LC3WTK 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 GFR600 is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This GFR60020LC3WTK is the size-600 unit with a 3/4 in NPT port, a 5 um filter element (code W), differential-pressure drain, low-pressure regulator type, a round gauge with bar scale, a reverse/check valve fitted, and the mounting bracket included. The bowl is aluminium alloy, which is standard at size 600. Max working (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 range spans sizes 200 to 600 with ports from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um filtration, gauge and thread options, and standard or low-pressure regulator types. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures for your application.

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.

| (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. |
| (blank) | Mounting bracket included. |

| C | Gauge shape: Round. 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.

A 3/4-in supply line feeding a spray-booth manifold: the 5 um element keeps water and fine particulate out of the finish, while the low-pressure regulator holds a gentle setting for atomising air.
Actuating big quarter-turn valves on a process line: the fitted check valve holds the downstream circuit if supply dips, and the regulator keeps actuator pressure steady with a local bar-scale reading.
A carton-forming and conveyor section on a packaging line: filtered, regulated air at the header keeps cylinders and diverters running, with the round gauge giving operators a local pressure check.
Size 600 with a 3/4 in NPT port suits lines that need larger supply connections; step down to 200/300/400 if your demand is smaller - we confirm exact flow from the datasheet curves on request, because AirTAC publishes flow as curves, not a single rating. This unit is the low-pressure (L) regulator type; its exact adjustment range is not published, so confirm it with us before ordering. The 5 um element (W) gives finer filtration than the 40 um standard. Drain is differential-pressure here; automatic and manual drains are available in the range. The gauge is the round external type with bar scale; the embedded square gauge with MPa/psi/bar scales is the alternative. Thread is NPT on this unit; PT is the standard thread and G is also an order option. Bracket included.
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 GFR600 as curves, not a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and sizing from the datasheet on request.
C is the round external gauge and 3 is the bar scale; the embedded square gauge with MPa/psi/bar scales is the alternative. The L marks the low-pressure regulator type - its exact adjustment range is not published, so confirm it with us before ordering.
