The AirTAC GFR20008MLJNT AirTAC Filter Regulator NPT1/4 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 PT1/4" 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 GFR20008MLJNT is an AirTAC GFR200 filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air with the standard 40 um element, then regulates downstream pressure in the low-pressure type configuration. This unit is built with 1/4 in NPT ports, a manual drain bowl in polycarbonate, no gauge fitted, no mounting bracket and no reverse/check valve. 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 options from 1/8 to 1 in and PT, G or NPT threads. Because flow for this series is published as curves rather than a single rated figure, 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.
| GFR200 | G-series filter regulator, 200 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". This body offers 06 = PT1/8", 08 = PT1/4". |
| 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. |
| (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. |
| (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.

Feeds filtered, regulated air to low-pressure actuation circuits on carton-sealing or wrapping machinery, with the manual drain emptied during scheduled line checks.
Conditions air for valve positioners and pilot-operated process valves on a skid, removing water and 40 um particulate before regulation to the pilot circuit.
Serves a workholding fixture or small clamping station at a machining cell, where an operator sets the low regulated pressure and drains the bowl manually at shift start.
Size 200 with 1/4 in NPT ports suits compact circuits; step up to GFR300/400/600 when the required flow demands a larger port. The manual drain means an operator opens the bowl drain during checks or shutdowns - choose the automatic or differential-pressure drain variants if the unit is installed where regular manual draining is impractical. The 40 um element is the standard grade; the W-suffix 5 um grade is available when finer filtration is needed. This is the low-pressure type, so confirm the regulated pressure your circuit needs before ordering. Thread is NPT here; PT and G (BSPP) are catalogue options. Bracket and gauge are orderable options on other variants of this series.
Flow for the GFR series is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. 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 no single flow number can be stated here. Tell us your application and we will confirm the flow figures from the datasheet on request.
The M in the code GFR20008MLJNT specifies a manual drain: the bowl is emptied by hand during maintenance rather than automatically. The N specifies that no gauge is fitted. AirTAC offers automatic and differential-pressure drain variants, and gauge options, elsewhere in the GFR series if your installation needs them.
