The AirTAC GFR60020ALJF2 AirTAC Filter Regulator PT3/4, 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 GFR60020ALJF2 is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 3/4 in PT port, the standard 40 um filter element, an automatic drain that ejects collected condensate without manual attention, and a low-pressure regulator suited to circuits that run well below standard line pressure. The embedded square gauge is scaled in psi so operators can read and set the working pressure directly, and the aluminium alloy bowl is the material used at size 600.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with port sizes from 1/8 in to 1 in, drain choices (differential-pressure, automatic or manual), a 5 um element option (code W), gauge scale options in MPa, psi or bar, and G or NPT thread variants to order. Flow is published as curves rather than a single rating, so ask us to confirm the figures against 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". |
| 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). |
| F | Gauge shape: Square. 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. |

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 pneumatic clamps, tool-change cylinders and chip-clearing blasts on a machining cell, with the psi gauge letting setters verify setpoint at the drop.
Installed at the point of use on a body-shop or trim line, cleaning water and scale out of the plant ring main and holding a stable low working pressure for air tools and fixtures.
Conditions the air feeding case erectors, sealing jaws and vacuum-assist cylinders on a packaging line, with the automatic drain coping with condensate on a continuously running shift.
Size 600 with a 3/4 in PT port is the right step when your line's flow demand sits above what 1/2 in and smaller ports serve; step up or down the 200/300/400/600 ladder against your consumption. Choose the automatic drain (this unit) where the installer cannot rely on regular manual draining; manual or differential-pressure drains are available in the family. The 40 um element is the standard grade for general plant air - specify the W code for 5 um where downstream equipment needs finer filtration. This is the low-pressure regulator type; its exact adjustment range is not published in the material we hold, so confirm it with us. Gauge scale here is psi; MPa or bar scales can be ordered. PT is the standard thread, with G (BSPP) and NPT as order options, and this configuration is supplied without a mounting bracket (brackets are available). Flow is published as curves, not a single rating - ask us to confirm sizing against your application 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 curves, not as a single rated figure, so we do not quote a number here. Tell us your working pressure and air consumption and we will confirm the flow figures from the datasheet for this exact model before you order.
The A in the code means the bowl drains collected condensate automatically, so no one has to bleed it by hand - useful on lines that run unattended. The L means this is the low-pressure regulator type rather than the standard type; its exact adjustment range is not published in our material, so confirm it with us. The unit also carries the standard 40 um element, a square gauge scaled in psi, and no reverse/check valve.
