The AirTAC GFR60020LJF1TK 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 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 GFR60020LJF1TK is a GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in one body. This size-600 unit is built with 3/4 in NPT ports, a 40 um standard filter element, and a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure differential across the bowl is high enough, so no manual draining routine is needed. It is the low-pressure type, carries an embedded square gauge scaled in MPa, and has a reverse/check valve fitted to hold the downstream setting if upstream supply is interrupted. Because it is size 600, the bowl is aluminium alloy. No mounting bracket is included with this configuration.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and can be ordered with manual or automatic drains, a 5 um element, G (BSPP) or NPT threads in place of the PT standard, different gauge scales, and with or without a bracket. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet and flow-curve 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". |
| (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. |
| 1 | Gauge scale: MPa. 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. |

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 gripper and clamp cylinders that index, fill and cap containers, with the check valve holding the setting through brief supply dips on a busy line.
Supplies a machine-tool clamping circuit where clean, moisture-reduced air at a stable low-pressure setting keeps workholding fixtures consistent across a shift.
Regulates the air to diverters, stoppers and gate actuators along a packaging or warehouse conveyor, with the 40 um element protecting valve spools from particulate wear.
Size and port are the first choice: step up through 200, 300, 400 and 600 as your line flow demand and pipe size grow - this unit is the 600 size with 3/4 in NPT ports. Drain type is a real decision: differential-pressure (as fitted here) drains itself with the pressure differential, automatic drains on a timed or level basis, and manual drains need someone to open the bowl. Filter grade is 40 um standard or 5 um (code W) where finer particulate removal is needed; this unit carries the 40 um element. The embedded square gauge is scaled in MPa here, with psi or bar scales and an external round gauge available as options. Thread is NPT on this model; PT is the catalogue standard and G (BSPP) is also orderable. A bracket can be added if you want panel or wall fixing - this configuration ships without one. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing against the curve before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow 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 flow demand and working pressure and we will confirm the datasheet and flow-curve figures for this exact 3/4 in, size-600 unit on request.
The L in the code marks the low-pressure regulator type, intended for applications set below the standard type's range; the exact adjustment range for this variant is not published in our sheet, so we confirm it on request. The differential-pressure drain (the default, with no A or M in the code) discharges collected condensate automatically when the pressure differential across the bowl is sufficient, so the bowl does not need routine manual draining.
