The AirTAC GFR60020LJC2G AirTAC Filter Regulator G3/4 Low-Pressure 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 AirTAC GFR60020LJC2G is a size 600 filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This configuration carries a G3/4 (BSPP) port, a 40 um standard filter element, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure drop across the element rises. It is the low-pressure type, intended for circuits set below standard regulator settings, and is fitted with an external round gauge reading in psi. The aluminium alloy bowl suits the larger 600 frame, and no mounting bracket is included in this variant.
This is a genuine AirTAC part in the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, manual or automatic drain options, a 5 um fine-filtration element, embedded square or external round gauges, and MPa, psi or bar scales. Flow figures for this family are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details 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). |
| 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. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |

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 filtered, regulated air to the actuator and gripper circuits of a bottle-filling and capping line, with the differential-pressure drain keeping condensate out of the valves on a continuously running header.
Mounted at the air-preparation panel of a case-packing or wrapping machine, filtering the incoming supply and holding a low set pressure for sensitive downstream components, with the psi gauge giving operators a local readout.
Installed ahead of a solenoid-valve manifold on a robotic assembly cell, removing water and pipe-scale at 40 um and regulating the branch pressure that feeds the cell's clamps and cylinders.
Size 600 with a G3/4 port is the largest GFR frame, so step up to it when your line's flow demand outgrows a 300 or 400 unit; the port step from 1/2 to 3/4 inch is the practical lever alongside published flow curves. The 40 um element in this code is the standard grade for general plant air; choose the W variant only when finer particulate protection is needed. Drain is differential-pressure here, which suits continuously running supply lines; pick automatic for unattended duty or manual where you want deliberate purge control. The round psi gauge suits US-facing panels; square gauges and MPa or bar scales are order options. Thread is G (BSPP); PT is the catalogue standard and NPT is available to order. No bracket is fitted, so plan your own mounting.
Because flow for this family is published as curves rather than a single rated figure, ask us to confirm sizing against your actual air demand 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 family as curves, not as a single rated figure, so we do not quote a number. Tell us your line's air demand and we will confirm sizing against the datasheet curves on request before you order.
The L in the code marks the low-pressure regulator type, intended for circuits set below standard regulator settings; the exact range for this variant is not published, so confirm your set point with us. This unit also uses a differential-pressure drain, which discharges collected condensate automatically as the filter element loads, with no manual purging needed.
