The AirTAC GFR60020LJC2 AirTAC Filter Regulator 3/4 in PT 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 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 GFR60020LJC2 is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and holds the downstream pressure. This 600-size unit is ported PT3/4 (3/4 in, PT thread), is the low-pressure regulator type, and carries the standard 40 um filter element with a differential-pressure drain. The aluminium alloy bowl suits higher-flow installations, a round psi gauge is fitted so operators can read the set pressure at a glance, and the unit is rated to 1.0 MPa (145 psi) inlet with an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in, PT as standard with G (BSPP) and NPT as order options, 40 um or 5 um (W) filtration, automatic, manual or differential-pressure drains, and embedded square or external round gauges in MPa, psi or bar scales. Flow is published as curves rather than a single rating, so send us your application and we will confirm the figures from the datasheet on request.

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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 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. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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.

Filtered, low-pressure regulated air for the clamp and lift cylinders on a bottling line, with the 3/4 in PT port feeding a manifold that serves several stations and the differential drain coping with condensate from a busy compressor room.
Clean, regulated air for tool-clamp and chip-door cylinders on a machining centre; the 40 um element protects directional valve spools from particulate and the round psi gauge lets setters verify pressure at the machine.
Regulated supply for diverter and stopper cylinders on a parcel sortation conveyor, where the low-pressure regulator type suits actuator circuits held below standard setpoints and the aluminium bowl handles the wet-air duty.
Choose the size by port and demand: 200 through 600 cover 1/8 in to 1 in ports, with this 600 unit at PT3/4 for higher-demand lines. Drain choice matters: differential-pressure (this unit) needs no routine attention in normal service, automatic (A) drains continuously, and manual (M) requires periodic bleeding. Filter grade is 40 um standard or 5 um with code W for finer protection. Gauges: embedded square as standard, external round in MPa, psi or bar scales - this unit carries the round psi gauge. Thread is PT standard with G (BSPP) and NPT available to order, and a mounting bracket is optional (this unit is supplied without one, code J). Flow is published as curves, not a single rating, so 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 rather than a single rated figure, so we do not quote a number here. Send us your line pressure, set pressure and downstream demand and we will confirm the flow from the datasheet on request.
L marks the low-pressure regulator type, built for circuits that hold a lower set pressure than the standard version. The exact adjustment span for this variant is not published in the standard table, so ask us to confirm it from the datasheet before ordering.
