The AirTAC GFR200-08LJF1TK 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 GFR200-08LJF1TK is an AirTAC GFR200-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size carries 1/4 in NPT ports and a polycarbonate bowl with a differential-pressure drain, which bleeds condensate automatically as the pressure differential across the element builds. The 40 um standard element handles general-purpose air cleaning, the embedded square gauge is scaled in MPa for direct setting, and a reverse/check valve is fitted so downstream pressure is held if the supply is interrupted. No mounting bracket is included with this configuration.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, an optional 5 um element (code W), gauge scales in MPa, psi or bar, and G (BSPP) or NPT thread options in place of the PT standard. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). This unit is the low-pressure regulator type; its exact adjustment range is not published in the material we hold, so please ask us to confirm it. Flow is published as curves rather than a single rating - we will confirm figures against 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.

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 clean, regulated air to the cylinder and gripper circuits of a cartoning or wrapping line, where the low-pressure regulator type suits machines that run their actuators well below full line pressure.
Conditioning shop-air down to a stable, filtered supply for bench-top test rigs and analytical equipment, with the check valve holding the setting if the building supply dips.
A compact filter-regulator stage at the inlet of a control cabinet or valve manifold, giving one filtered, regulated take-off point for solenoid valves and pilot circuits on a 1/4 in drop.
Choose the size and port step against the air demand of the circuit: this GFR200 unit has 1/4 in NPT ports, and larger sizes (300/400/600) step up in port and body size. Drain type is a real choice - differential-pressure (as fitted here) needs no attention, automatic drains continuously, and manual suits infrequently attended points. The 40 um element is standard; specify the W option for 5 um where finer filtration is needed. Gauge scale (MPa, psi or bar) and thread (PT standard, G or NPT to order) should match the rest of the installation, and a bracket can be ordered if this no-bracket configuration needs panel fixing. Because flow is published only as curves and not as a single rated figure, 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 flow for this series as curves, not as a single rated figure, so we do not quote a number that could mislead your sizing. Tell us your application and we will confirm the relevant flow figures from the datasheet on request before you order.
Both are part of the code. With no drain letter, the GFR series defaults to the differential-pressure drain, which ejects condensate automatically as it accumulates - no manual draining routine. F1 decodes as the embedded square gauge scaled in MPa; psi or bar scales and an external round gauge are available as options if you prefer.
