The AirTAC GFR20008MLJF2 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 GFR20008MLJF2 is an AirTAC GFR200 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one compact body. This configuration has a PT1/4 (1/4 in) port, a manual drain on the polycarbonate bowl, a 40 um filter element, the low-pressure regulator type and a built-in square gauge scaled in psi. No mounting bracket is fitted. Maximum 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. The GFR series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options include automatic or differential-pressure drains, a 5 um element (code W), G (BSPP) or NPT threads, alternative gauge scales and an external round gauge. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application.

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. |
| 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. |
| (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.

On a fixture-clamping circuit that runs cylinders at reduced pressure, this filter regulator cleans the supply and holds the set pressure at the 1/4 in take-off point.
Feeding hand tools and small actuators at a workbench, the manual-drain bowl lets an operator blow down accumulated water at the start of each shift.
On packaging lines with light-duty cylinders and air jets, the 40 um element protects downstream valves from particulate while the low-pressure regulator trims the supply.
Size and port step up from 200 to 600 as air demand grows; this unit sits at the 200 size with a PT1/4 port. Because the drain is manual, plan a routine blow-down of the polycarbonate bowl, or choose the automatic or differential-pressure drain versions if unattended water removal matters. The 40 um element is the standard grade; specify code W for the 5 um element when finer filtration is needed. The square gauge here reads in psi, with MPa and bar scales available and an external round gauge optional. PT thread is standard on this model, with G (BSPP) and NPT offered as order options, and the J suffix means no mounting bracket is included. Flow is published as curves, not a single rating, so send us your application details 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. 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 we do not quote a number here. Send us your line pressure and expected air demand and we will confirm the flow curve and sizing from the datasheet before you order.
This is the L low-pressure type, and AirTAC does not publish a single adjustment range for it in the standard tables; standard-type GFR units with a manual drain adjust from 0.05 to 0.9 MPa. Ask us and we will confirm the exact low-pressure range from the datasheet.
