The AirTAC GFR20008LJF1T AirTAC Filter Regulator NPT1/4 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 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 GFR20008LJF1T 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 built for 1/4 in NPT ports and carries the low-pressure regulator type, a 40 um standard filter element, and a differential-pressure drain that discharges collected condensate as air flows through. The embedded square gauge reads set pressure in MPa, the polycarbonate bowl suits non-freezing installations from -5 to 70 C, and maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and catalogue options including 5 um (W) filtration, automatic or manual drains, gauge scale choices, a reverse/check valve (K), and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rating, so we confirm flow and full datasheet figures 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.

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.

Instrument and fixture test circuits often run at low set pressures. This low-pressure GFR200 cleans the shop air to 40 um and regulates the bench feed at each NPT1/4 drop, with the MPa gauge showing the setpoint at a glance.
Spray guns call for a gentle, steady regulated feed. Fitted at the booth drop in 1/4 in NPT, this unit filters water and particulate from the shop air and holds the low set pressure the gun needs, while the differential-pressure drain sheds condensate as air passes.
Clamp and hold-down actuators on a packaging conveyor work best with soft, low set pressures. This GFR200 filters and regulates the clamp circuit feed, and the square MPa gauge lets the line technician verify the setting without tools.
Size and port step up with flow demand: GFR200 with its 1/4 in port suits compact circuits, while GFR300, 400 and 600 serve larger ports and heavier demand. Choose the drain: differential-pressure (this unit, drains with flow), automatic (A) for hands-off drainage, or manual (M) for on-demand draining. Filter grade is 40 um standard; specify W for 5 um where finer protection matters. This unit is the low-pressure regulator type for lower set-pressure circuits - confirm the adjustment range against your setpoint before ordering. The F1 code means the embedded square gauge with MPa scale; psi or bar scales and an external round gauge are options. PT is the AirTAC standard thread; this unit is ordered with NPT, and G (BSPP) is also available. J means no mounting bracket is included.
Because flow is published as curves rather than a single rating, 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 the GFR series as curves rather than a single rated figure, so we do not quote a number. Tell us your application and downstream demand and we will confirm sizing from the datasheet on request.
F1 specifies the square pressure gauge fitted to the regulator, reading in MPa. Psi (2) and bar (3) scales are catalogue options, and an external round gauge can be specified in place of the embedded square gauge.
