The AirTAC GFR60020MLJC2WTK 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR60020MLJC2WTK is a size 600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body, with a 3/4 in NPT port. This configuration carries the W-coded 5 um filter element for finer dirt and condensate removal, a manual drain for the aluminium alloy bowl, a low-pressure type regulator, a round pressure gauge reading in psi, and a built-in reverse (check) valve. It is ordered without a mounting bracket. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in and options including drain type, filter grade, gauge style and scale, thread form (PT standard, G and NPT to order) and bracket. Flow is published by AirTAC as curves rather than a single rated figure, and the exact regulation range of the low-pressure type is not published in the catalogue sheet, so ask us and we will 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". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. 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. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

On a water-treatment or chemical dosing skid, this unit filters the plant air to 5 um and holds a low, stable supply pressure to the diaphragm valves' pilot circuit, with the psi gauge giving operators a local reading at the panel.
In a light assembly press or pneumatic clamping fixture running at reduced pressure, the regulator sets the working pressure while the 5 um element and bowl keep condensate and scale out of the cylinder and valve seals.
As a machine-drop unit on a cartoning or wrapping line, it cleans and regulates the air feeding the actuators and jet nozzles; the reverse (check) valve holds downstream pressure if the main supply dips, and the manual drain is emptied during changeover.
Choose the GFR size by the port and flow your line needs: size 600 with a 3/4 in port sits at the top of the range for higher-demand circuits. Pick the filter grade by air quality: 40 um is the standard element, while this unit's 5 um (W) element suits finer protection downstream. Drain type is a real choice: differential-pressure (default), automatic, or manual as coded here - manual means an operator opens the drain periodically. Gauge options are the embedded square gauge or an external round gauge, with MPa, psi or bar scales; this unit has the round gauge in psi. Thread is PT as standard with G (BSPP) and NPT as order options, and a bracket is optional (this code omits it). Note that this is the low-pressure type regulator. Because flow is published as curves rather than a single rating, 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. 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 number, so we do not quote a figure here. Send us your line pressure, downstream pressure target and expected air demand, and we will confirm the flow figures from the datasheet on request before you order.
The M in the code specifies a manual drain: an operator opens the bowl drain periodically to remove accumulated condensate, which suits attended installations or points already covered by a maintenance routine. The alternatives in the GFR range are the differential-pressure drain (the default, which dumps automatically on a pressure drop) and the automatic drain (code A), and the bowl on this size 600 unit is aluminium alloy.
