The AirTAC GFR60020ALJC2G 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 automatic 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 GFR60020ALJC2G is a size-600 filter regulator: it removes water and particulate from compressed air and reduces pressure to your setpoint in a single body. This configuration carries a G3/4 port, an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, and the low-pressure regulator type for applications that work at reduced supply pressures. A round external gauge scaled in psi is fitted so the downstream setting can be read directly, and the size-600 bowl 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 GFR filter-regulator family is published in 200, 300, 400 and 600 sizes with a choice of drain type, 40 um or 5 um (W) filtration, gauge style and scale, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures for your application 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.

|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| A | Drain: Automatic 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.

Point-of-use conditioning for spray booths and coating heads, where the air must be dried of water and particulates and held at the reduced pressure the applicator calls for - a job the low-pressure regulator type is built around.
Supplying clean, regulated air to the cylinders and grippers on cartoning and case-packing conveyors, with the automatic drain clearing condensate on its own so the line keeps running without operator attention.
The filter-and-regulate stage of a plant-air distribution panel feeding valve islands and downstream circuits, with the fitted psi gauge giving operators a direct readout of the delivered pressure.
Start with the port and size step: GFR covers 200, 300, 400 and 600, and the 600 size with a 3/4 port suits lines whose air demand sits above what the smaller bodies are sized for - match the step to the flow your circuit needs. Choose the drain to match site practice: automatic (this unit) drains itself, manual needs an operator, and the default differential-pressure type drains on the pressure drop across the element. Pick 40 um for general plant air or the W code for 5 um where downstream equipment needs finer filtration. Gauge style and scale (square embedded or external round; MPa, psi or bar) are decodable choices, as are PT versus G or NPT threads and whether a mounting bracket is included - this unit is supplied without a bracket.
Because AirTAC publishes flow only as curves and not as a single rated number, 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 this series as curves rather than a single rated figure, so we do not quote one number. Tell us your application and we will confirm the flow and sizing data from the datasheet on request.
This unit's A code means an automatic drain, which ejects collected condensate from the bowl without operator action. The alternatives in the series are a manual drain, which is emptied by hand, and the default differential-pressure drain, which discharges based on the pressure drop across the filter element.
