The AirTAC GFR20008MLJF3TK AirTAC Filter Regulator 1/4 NPT Bar Gauge 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 GFR20008MLJF3TK is an AirTAC GFR200 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is a 1/4 in NPT ported, low-pressure type unit with a manual drain, a 40 um standard filter element, a polycarbonate bowl, an embedded square gauge scaled in bar, a reverse/check valve fitted, and no mounting bracket.
It is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with port options from 1/8 to 1 in and a choice of drain, filter grade, gauge, thread and bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and operating temperature is -5 to 70 C (non-freezing). Rated flow is published as curves rather than a single figure, so we confirm flow and other datasheet values 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. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 3 | Gauge scale: bar. 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. |
| 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.

Filters and regulates the air feeding clamp cylinders on an assembly fixture. The bar-scale square gauge lets an operator verify the set pressure at a glance, and the fitted check valve holds the circuit against backflow between cycles.
Conditions the pilot air feeding a valve positioner or actuator on a process line. The low-pressure type regulator suits circuits set well below standard line pressure, and the manual drain lets maintenance purge accumulated water during shift checks.
Feeds filtered, regulated air to an air-knife station that dries cartons or blows debris off products on a packaging conveyor. The 40 um element keeps particulate out of the nozzles, and the gauge confirms the blow-off pressure is held steady.
The real choices in this family are the size and port step, matched to the flow your line needs - this unit is the 200 size with a 1/4 in NPT port. Drain type is a maintenance decision: this one is manual, meaning the bowl is purged at service intervals; automatic and differential-pressure drains are available in the range. The 40 um element is standard, with a 5 um (W) element for finer filtration. The gauge here is the embedded square type scaled in bar, with MPa or psi scales and an external round gauge as options. Thread is NPT on this code; PT is the standard and G (BSPP) can be ordered. No bracket is fitted (code J). The low-pressure type (L) regulator is intended for circuits set below standard line pressure; its exact adjustment range is not published, so ask us to confirm it. Rated flow is published as curves, not a single number - send us your flow requirement and we will confirm sizing against the datasheet before you order.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this range as curves, not as a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Tell us your line pressure and the flow your application needs, and we will confirm suitability against the datasheet curves on request before you order.
Water collected in the polycarbonate bowl is released by operating the drain manually, so this unit suits installations that are checked at regular service intervals. If you would rather not rely on manual purging, the GFR range also offers automatic and differential-pressure drain options in the same sizes.
