The AirTAC GFR60020LC2WTK 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 GFR60020LC2WTK is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body. This size 600 unit has 3/4 in NPT threads, a 5 um filter element (code W) for finer air quality than the 40 um standard, and a differential-pressure drain that bleeds the bowl automatically as air flows through. The regulator is the low-pressure type, intended for applications that run at set pressures below the standard range. It is fitted with a round psi gauge and a reverse (check) valve, and includes a mounting bracket. The bowl on this largest G-series frame is aluminium alloy. 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 G-series filter-regulator line spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, thread options PT (standard), G and NPT, drain choices, 40 um or 5 um elements, gauge styles and scales, and standard or low-pressure regulation. Flow is published as curves rather than a single rating, so ask us to confirm sizing 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.

| C | Gauge shape: Round. C is round, F is square. |

| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

On a paint or coating line running atomizing air at reduced pressure, this unit strips water and fine particulate before the gun and holds the low set pressure steady so finish quality does not drift through a shift.
Feeding the low-pressure air cylinders and air-blow nozzles on a carton-sealing or labelling conveyor, the 5 um element protects valve seals from water and grit while the regulator keeps actuator speeds repeatable.
On a laboratory or pilot plant skid where instruments and pneumatic valves run well below standard line pressure, the low-pressure regulator type and check valve give a stable, protected supply at the 3/4 in plant drop size.
Size and port step up together across the G-series (200/300/400/600), so choose the size whose flow curve covers your demand at your operating pressure - we can check the curve against your application. This code is the low-pressure regulator type; its exact regulation range is not published in the material we hold, so confirm your required set pressure with us before ordering. The 5 um element (W) suits finer air quality than the 40 um standard. The differential-pressure drain on this unit is self-acting with flow; automatic (A) and manual (M) drains are available elsewhere in the family. The gauge here is the external round style with a psi scale; an embedded square gauge and MPa or bar scales are the other catalogue options. Thread is NPT on this code, PT is the catalogue standard, and G (BSPP) is available to order. A mounting bracket is 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 this series as curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Send us your application details and we will confirm the flow curve and sizing against the datasheet on request before you order.
It means the regulator is built for applications that hold a set pressure below the standard regulator range. The exact range for the low-pressure type is not published in the material we hold, so tell us your required set pressure and we will confirm suitability on request. Everything else on this code decodes normally: NPT3/4 ports, 5 um element, differential-pressure drain, round psi gauge, check valve and included bracket.
