The AirTAC GFR60020ALJC3WT AirTAC Filter Regulator NPT3/4 Low-Pressure 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 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 GFR60020ALJC3WT is a GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size-600 unit is built with a 3/4 in NPT port, an automatic drain that clears collected condensate without operator attention, a 5 um filter element for finer cleaning than the standard 40 um grade, and the low-pressure (L) regulator type for circuits operating at reduced line pressure. A round pressure gauge with a bar scale is fitted, the size-600 bowl is aluminium alloy, maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), no reverse/check valve is fitted, and no mounting bracket is included (code J).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, drain choices of differential-pressure, automatic or manual, 40 um standard or 5 um (W) filtration, embedded square or optional external round gauges with MPa, psi or bar scales, and PT, G or NPT thread options. Flow for this model is published as curves rather than a single rating, so ask us to confirm the 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 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. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT 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.

Conditioning the air feed to a low-pressure paint spray line: the 5 um element removes water and fine particles that cause finish defects, while the regulator holds a steady reduced pressure at the gun and the bar-scale gauge gives the operator a visible set point.
Feeding the low-pressure clamping and hold-down cylinders on a packaging line, where the automatic drain keeps condensate out of the valves and actuators through multi-shift running without an operator having to bleed the bowl.
Supplying air knives or blow-off nozzles that clear dust and debris from products travelling on a conveyor, with the 3/4 in port and 5 um filtration protecting the nozzles from moisture and grit.
Size and port set the capacity: within GFR, sizes 200, 300, 400 and 600 step up in port and flow, and this unit sits at the top of the range with a 3/4 in NPT port. The drain here is automatic, which suits unattended installations; manual and differential-pressure drains are the alternatives across the family. The 5 um (W) element is the finer option against the 40 um standard. The fitted round gauge reads in bar; embedded square gauges and MPa or psi scales are available on other variants. Thread is NPT here, with PT as the standard and G (BSPP) as order options, and this variant carries no mounting bracket. This is the low-pressure (L) regulator type; its exact adjustment range is not published, so we confirm it on request. Operating temperature is -5 to 70 C (non-freezing). 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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and datasheet figures for this model on request before you order.
The A in this code specifies an automatic drain, which ejects collected condensate without operator attention. GFR units are also available with manual or differential-pressure drains - tell us which suits your installation and we will point you to the matching variant.
