The AirTAC GFR60020ALJNT AirTAC Filter Regulator NPT3/4 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 GFR60020ALJNT is a size-600 GFR filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built with a 3/4 in NPT port, an automatic drain that expels collected condensate without manual attention, a 40 um standard filtration element, and the low-pressure regulator type. The 600-size bowl is aluminium alloy, and this unit is supplied without a gauge and without a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, automatic, manual or differential-pressure draining, and a 5 um element (code W) where finer filtration is needed. Rated flow for this series is published as curves rather than a single figure, so ask us to confirm the datasheet and sizing figures 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". |
| 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. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 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.

Point-of-use conditioning at a spray booth or coating line: the 40 um element strips water and pipe scale before the atomising air header, while the low-pressure regulator holds a gentle, steady header pressure for finish consistency.
Feeding air knives and blow-off nozzles on a carton or bottle conveyor, where the automatic drain keeps condensate out of the nozzle tips during continuous shifts and the low-pressure setting suits delicate product blow-off.
Conditioning a bench air drop in a test laboratory or pilot plant: particulate and moisture are filtered out ahead of sensitive instruments, and the low-pressure regulator trims supply pressure down to what the bench circuit requires.
Step up or down through the GFR sizes (200/300/400/600) so the port and body match the flow your line needs; this unit is the 600 size with a 3/4 in NPT thread. Choose the drain to suit access: automatic (this unit) for unattended condensate removal, manual where you want controlled purging, or the differential-pressure default. Filtration is 40 um standard; specify the W code for 5 um if downstream equipment demands finer air. This is the low-pressure regulator type, so confirm the working band suits your circuit before ordering. Gauge (round or square, MPa/psi/bar scale) and bracket are order options if you want them fitted. Because flow for this series is published as curves and not a single rating, send us your application details and we will confirm sizing against the datasheet before you order.
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 GFR600 series as performance curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and the flow your equipment needs, and we will confirm the sizing against the datasheet on request before you order.
The A in the code GFR60020ALJNT specifies the automatic drain, which ejects collected condensate from the aluminium bowl without anyone opening it - useful for unattended or hard-to-reach installations. Manual-drain and differential-pressure-drain versions of the same GFR600 filter regulator are available if you prefer a different arrangement.
