The AirTAC GFR20008LJF2G AirTAC Low-Pressure Filter Regulator G1/4 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR20008LJF2G is a GFR200 filter regulator: one compact body that removes water and particulate from compressed air and regulates downstream pressure. This configuration has a G1/4 (BSPP) port, the standard 40 um filter element, a differential-pressure drain, the low-pressure regulator type, and an embedded square gauge scaled in psi. The polycarbonate bowl lets you see condensate at a glance, and no mounting bracket is included.
GFR200 is the entry size of AirTAC's G-series filter regulator line, which steps up through GFR300, GFR400 and GFR600 with larger ports and greater flow capacity. Across the range you can select drain type, filter grade, gauge style and scale, thread (G or NPT as well as PT standard) and bracket options. This is a genuine AirTAC part. Flow is published as curves rather than a single rating, so we 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.

| 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. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |

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 a low-pressure clamping circuit on a furniture assembly line, where filtered, moisture-reduced air at a steady set pressure protects the clamp cylinders and the square psi gauge gives a local readout at the machine.
Conditioning shop air for a laboratory's pneumatic sample-handling manifold, with the 40 um element catching pipe scale and rust before it reaches sensitive actuators and valves.
Supplying cylinder actuation on a carton-sealing machine at its G1/4 air inlet, where one compact filter regulator body handles both air preparation duties without a separate second component.
The real choices when specifying a GFR unit: size and port (GFR200 with G1/4 is the entry step; GFR300/400/600 step up in port and flow capacity), drain type (differential-pressure as here, automatic code A, or manual code M), filter grade (40 um standard, 5 um with code W), gauge (this unit carries the embedded square gauge in psi; MPa or bar scales and an external round gauge are options), thread (PT standard; G and NPT are orderable) and bracket. Note that this unit is the low-pressure regulator type and carries no mounting bracket; its exact adjustment range is not published, so we confirm it against your set point on request.
Flow for the GFR series is published as curves, not a single rated figure, so send us your air demand and working pressure and we will confirm sizing from 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. Tell us your required flow and working pressure and we will confirm from the datasheet whether this G1/4, 40 um, low-pressure unit suits your application.
This unit uses the differential-pressure drain, the G-series default: condensate collected in the polycarbonate bowl is discharged as the pressure differential across the filter element builds. Automatic (code A) and manual (code M) drains are catalogue options on GFR units if you prefer a different arrangement.
