The AirTAC GFR60020MLJNWT AirTAC Filter Regulator NPT3/4 Low-Pressure 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 GFR60020MLJNWT is a filter regulator: filtration and pressure regulation combined in one body, removing water and particulate from compressed air and then regulating the downstream pressure. This 600-size unit has 3/4 in NPT ports (PT is the standard thread; G and NPT are catalogue order options), a 5 um filter element (code W), a manual drain on the aluminium alloy bowl, and the low-pressure regulator type (code L). No gauge is fitted (code N), no mounting bracket is included (code J), and no reverse/check valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
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, and is ordered with a choice of drain type (differential-pressure, automatic or manual), filter grade (40 um standard or 5 um with W), gauge and scale, thread (PT standard; G and NPT as options), bracket, and low-pressure type. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 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.

On a spray booth or robotic paint line, the 5 um element removes fine particulate before air reaches the guns, and the low-pressure regulator type suits circuits that run at reduced set pressures for finishing work.
Jet looms and textile blowing stations run on regulated low-pressure air; the 3/4 in NPT ports serve larger supply lines and the manual-drain aluminium bowl is emptied during shift checks.
On a bottling or canning line, this filter regulator conditions the air feeding grippers and stopper actuators, with the manual drain cleared as part of planned maintenance rounds.
Size and port set the capacity: this unit is size 600 with 3/4 in NPT ports, the largest step in the GFR range, so match the port step to the air demand of the circuit rather than to the existing pipe size alone. Drain choice matters in daily use: this configuration uses a manual drain, so the bowl must be drained by hand on a schedule; automatic (A) and differential-pressure (blank) drains are available on other codes if unattended drainage is required. The 5 um element (code W) suits circuits needing finer particulate removal than the 40 um standard. No gauge is fitted, so add an external gauge if the set pressure must be read at the unit. Flow for the GFR series is published as curves, not a single rating - send us your flow and pressure requirements and we will confirm sizing against 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 rather than a single rated figure, so we do not quote a number here. Tell us your required flow and working pressure and we will confirm the sizing from the datasheet on request.
Code M means the aluminium alloy bowl is drained by hand, which suits installations where an operator can bleed the bowl on a schedule. If unattended drainage is needed, the same GFR600 size is available with automatic (A) or differential-pressure (blank) drain on other codes.
