The AirTAC GFR600C20LJF2WK AirTAC Filter Regulator PT3/4 5 um 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 See datasheet 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 GFR600C20LJF2WK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a 5 um filter element (the finer of the two published grades), a differential-pressure drain that bleeds condensate automatically whenever the pressure differential across the element is high enough, and a reverse/check valve that holds downstream pressure when the upstream supply is lost. It is the low-pressure type, intended for circuits set well below standard line pressure, and it ships with an embedded square gauge scaled in psi. The PT3/4 port suits 3/4 in air lines, and 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, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, standard or low-pressure regulation, square or round gauges in MPa, psi or bar scales, and PT, G or NPT threads. We confirm flow and datasheet figures on request, since flow is published as curves rather than a single rating.

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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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.

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 a filtered, regulated air drop serving carton-forming and sealing heads that run on a low-pressure circuit, with the 5 um element keeping fine debris out of the sealing cylinders and the check valve holding the circuit during supply dips.
Sits at the booth drop to knock out water and fine particulate before air reaches spray equipment, with the low-pressure regulator holding the gentle, stable setting that finishing work demands and the psi gauge giving a direct read at the point of use.
Supplies pneumatic actuators and sample-handling cylinders on a process skid, where the 5 um grade protects sensitive pilot valves, the reverse/check valve preserves the set pressure through upstream fluctuations, and the aluminium bowl handles continuous duty.
Start with the port step: this unit is PT3/4 on the size 600 body, the largest in the GFR range, so it suits the high-flow end of a distribution main. Match the element to the duty: 40 um is the standard grade for general line protection, while the 5 um element fitted here is the choice when downstream valves and actuators need finer protection. The differential-pressure drain fitted here needs no daily attention, but if your line runs at low and steady pressure an automatic drain (code A) or a manual drain (code M) may suit better. The gauge is square and psi-scaled; MPa and bar scales and an external round gauge are order options. PT is the standard thread, with G (BSPP) and NPT available to order, and this code omits the mounting bracket. Because flow is published as curves rather than a single rated figure, 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. Without the K option, air cannot flow back 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 figure here. Tell us your line pressure, set pressure and expected air demand, and we will confirm the flow from the datasheet and check the sizing against your application before you order.
The W in the code selects the 5 um element, the finer of the two published grades (40 um is standard), for protection of sensitive downstream valves and actuators. The K selects a reverse/check valve, which holds the regulated downstream pressure if the upstream supply drops. Both are order options on the GFR family, and the differential-pressure drain and psi-scaled square gauge in this code are likewise read straight from the model number.
