The AirTAC GFR20008MLF2TK AirTAC Filter Regulator NPT1/4 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 GFR20008MLF2TK 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 size 200 with a 1/4 in NPT port, a manual drain, the standard 40 um filtration element, the low-pressure regulator type, an embedded square gauge scaled in psi, and a reverse/check valve fitted; a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). On this size the bowl is polycarbonate.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (code W) filtration, gauge scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures for your application before ordering.

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. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 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.

Assembly-cell clamping fixtures that hold workpieces at low regulated set points get clean, moisture-reduced air from this filter regulator, with the check valve holding the downstream circuit if supply pressure dips.
A workshop test bench running small-bore actuators and air tools from a 1/4 in NPT drop uses this unit to filter the shop air and set a stable, low test pressure read locally on the psi gauge.
A woodshop or paint finishing booth feeding low-pressure spray guns from a 1/4 in line relies on this unit to strip water and particulate that would otherwise blemish the finish, while regulating the gun supply.
Pick the size step (200/300/400/600) and port to match the flow your circuit needs - here that is size 200 with a 1/4 in NPT port. This unit is the low-pressure regulator type, so it suits circuits held at low set points; we confirm the exact range from the datasheet on request. The M code gives a manual drain, meaning the bowl is drained by hand; automatic (A) and differential-pressure (default) drains are available if you want hands-off condensate removal. Filtration is the 40 um standard element; specify 5 um (code W) for finer protection. The square gauge is scaled in psi, with MPa and bar scales and an external round gauge as options. PT is the standard thread, with G and NPT as catalogue options, and this configuration includes a mounting bracket plus a reverse/check valve (K). Because flow is published as curves rather than a single rating, ask us to check the curve against your application before ordering.
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 family as curves, not as a single rated number, so we do not quote a figure here. Tell us your application and line conditions and we will confirm the flow curve and sizing from the datasheet on request before you order.
The M code means condensate collected in the polycarbonate bowl is released by hand, so someone should drain it as part of routine checks. If you prefer hands-off removal, the same GFR family is available with an automatic drain (code A) or the default differential-pressure drain.
