The AirTAC GFR20008MLF2K AirTAC Filter Regulator PT1/4 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 GFR20008MLF2K is an AirTAC GFR200 filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air and regulates the downstream pressure. This configuration is 1/4 in PT threaded, has a manual-drain polycarbonate bowl, a 40 um standard filter element, the low-pressure regulator type, an embedded square gauge reading in psi, and a built-in check valve; the 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).
This is a genuine AirTAC part. The GFR series is made in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options including automatic or differential-pressure drains, a 5 um element (code W), alternative gauge scales, and G (BSPP) or NPT threads. AirTAC publishes flow as curves rather than a single rated figure, so ask us to confirm the flow and datasheet 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. |
| (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. |
| (blank) | PT 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.

Filtering the shop air and holding a steady low regulated pressure to spray guns on a finishing line, with the built-in check valve blocking backflow from downstream equipment.
Supplying clean, low-pressure regulated air to sealing jaws and small actuators on a packaging line, with the manual drain suited to a scheduled maintenance routine.
Regulating low clamping pressure on a machining fixture that holds finished or soft parts without marking them, while the 40 um element keeps debris out of the clamp cylinders.
Size the unit by port and expected flow: 200 is the compact size in the range, and stepping up to 300, 400 or 600 gives a larger port and more flow. Choose the drain to match maintenance practice: this unit is manual (code M), so the bowl is drained on your schedule; automatic and differential-pressure drains are available on other codes. The 40 um element is standard; specify W for the 5 um grade. The embedded square gauge on this unit reads in psi, with MPa and bar scales available as alternatives. PT thread is the standard; G (BSPP) and NPT are catalogue options to order. Flow 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and full datasheet figures for this unit on request.
L marks the low-pressure regulator variant, intended for applications where the set pressure stays low; the exact range is not published in our data sheet, so confirm it with us. F2 means the embedded square gauge is fitted and reads in psi (MPa and bar scales are alternatives). M means manual drain, so you drain the polycarbonate bowl on your own schedule.
