The AirTAC GFR60020ALJF1WT AirTAC Filter Regulator, NPT3/4, 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 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 GFR60020ALJF1WT 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 NPT port, a 5 um filter element (the finer of the two published grades), an automatic drain that expels collected condensate without manual attention, a low-pressure regulator type, and a factory-fitted embedded square gauge reading in MPa. The 600-size bowl is aluminium alloy, and this unit is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, drain choices (differential-pressure, automatic, manual), 40 um standard or 5 um elements, gauge and thread options. Flow is published as curves rather than a single rating, so we confirm the datasheet and flow 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.
| 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). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 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.

Feeding filtered, low-pressure regulated air to a pneumatic press or clamping fixture circuit, with the 5 um element protecting directional valves and cylinders from particulate carryover.
Conditioning the 3/4 in main feeding conveyor diverters and packaging actuators, where the automatic drain keeps condensate out of the circuit during continuous shifts.
Installed at a drop leg serving a production cell, combining water and particle removal with low-pressure regulation in one body and a square MPa gauge for local setting.
Step up through sizes 200, 300, 400 and 600 against the flow your line needs - the 600 body with its 3/4 in port sits at the top of the range for higher-demand circuits. Choose the drain to suit access: automatic (this unit) for unattended duty, manual where you prefer a controlled blow-down, or the differential-pressure default. Pick 5 um (this unit) where downstream equipment is sensitive, or the 40 um standard for general protection. Gauge scale (MPa, psi or bar), thread (PT standard, G or NPT to order) and bracket inclusion are all decodable choices.
Flow for this family is published as curves, not a single rated figure, so 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 flow for the GFR family as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and datasheet figures for this exact model on request before you order.
The W in the code specifies the 5 um element (the finer option; 40 um is standard), and the A specifies an automatic drain that expels condensate without manual attention. The L specifies the low-pressure regulator type; its exact adjustment range is not published in the catalogue, so we confirm it on request. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature is -5 to 70 C, non-freezing.
