The AirTAC GFR20008MLF2WG AirTAC Filter Regulator G1/4, 5 um 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 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 GFR20008MLF2WG is an AirTAC GFR200 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a G1/4 (BSPP) port, the finer 5 um filter element, a manual drain on the bowl, and the low-pressure regulator type. A square pressure gauge with a psi scale is fitted and the mounting bracket is included. The polycarbonate bowl suits this 200 size, 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 range spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options including automatic, manual or differential-pressure drains, 40 um or 5 um elements, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm 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. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) 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.

Feeding filtered, regulated low-pressure air to carton-sealing and wrapping heads on a packaging line, with the manual drain bled by an operator at shift start.
Supplying low-pressure clamp circuits on CNC fixture manifolds, where the 5 um element helps keep directional valves and clamp cylinders free of fine contamination.
Conditioning air for low-pressure spray guns in a paint booth, combining water and particle removal with the reduced regulated pressure the gun circuit requires.
Choose the size by port and flow: this 200 size carries a G1/4 port, and stepping up to 300, 400 or 600 gives larger ports and flow. The 5 um element (code W) suits air that must be cleaner than the 40 um standard provides; pick 40 um where only coarse protection is needed. The manual drain (code M) is bled by hand, which suits attended installations; automatic or differential-pressure drains are available for unattended ones. This is the low-pressure regulator type, so confirm the regulated pressure your circuit needs before ordering. Gauge scales come in MPa, psi or bar - this unit is psi. The thread here is G (BSPP); PT is the standard and NPT is an order option. A mounting bracket is included. 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this series as curves rather than a single rated figure, so we do not quote a number here. Send us your flow and pressure requirements and we will confirm the datasheet figures for this exact model on request.
The manual drain (code M) is bled by hand, which suits attended installations; automatic or differential-pressure drains are available for unattended ones. The 5 um element (code W) is the finer of the two published grades - the 40 um element is the standard choice where only coarse protection is needed.
