The AirTAC GFR600-20LJF2W AirTAC Filter Regulator 3/4 in PT, 5 um 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 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 GFR600-20LJF2W is a filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This 600-size unit carries a 3/4 in PT port, the 5 um (code W) filter element instead of the 40 um standard, a differential-pressure drain that bleeds collected condensate automatically whenever the pressure drop across the element is high enough, and a fitted embedded square gauge scaled in psi. It is the low-pressure (L) type, and the 600-size bowl is aluminium alloy rather than polycarbonate. No mounting bracket is included on this configuration.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge scale options in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 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.

Feeding clamps and fixtures on a CNC machining cell, where the 5 um element keeps spool valves clean and the low-pressure regulator holds a gentle, stable clamp force at the 3/4 in supply.
Conditioning house compressed air before sample-prep or analytical bench equipment, where fine 5 um filtration and a psi-scaled gauge let technicians set and read a low working pressure directly.
Supplying the cylinder and actuator bank on a cartoning or wrapping line, with the differential-pressure drain clearing condensate during production and the aluminium bowl standing up to continuous duty.
Step up or down the size ladder (200 / 300 / 400 / 600) against the port and flow your line needs; this unit sits at the top of the range with a 3/4 in PT port. Drain options are differential-pressure (this unit, which purges on pressure drop), automatic, or manual; the 5 um W element suits air that feeds sensitive valves or instruments, while 40 um is the standard choice for general circuits. The fitted square gauge reads in psi, and MPa or bar scales are available instead. PT is the standard thread; G (BSPP) and NPT are order options. This configuration has no bracket. Because flow is published as curves rather than a single rating, send us your application details and we will confirm sizing from 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 GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and the flow your application needs, and we will confirm the correct size from the datasheet on request.
The J in the code means this configuration is supplied without a mounting bracket; bracketed versions of the GFR600 are available. The L code marks the low-pressure regulator type, which is intended for lower working pressures than the standard version - its exact adjustment range is not published in the catalogue, so ask us to confirm it for your setpoint before ordering.
