The AirTAC GFR200C08LJF2TK 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 See datasheet 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 GFR200C08LJF2TK is an AirTAC GFR200 filter regulator: water and particulate filtration plus pressure regulation in a single body, with a 1/4 in NPT port. This configuration is the low-pressure type, so the downstream regulator setting is intended for circuits that run at reduced pressure rather than full line pressure. It carries the standard 40 um filter element, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, an embedded square gauge scaled in psi, and a built-in reverse (check) valve that holds the downstream setting when upstream supply is interrupted. The J suffix means no mounting bracket is supplied. 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 family is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and with options including manual or automatic drains, a 5 um element (code W), gauge scale in MPa, psi or bar, and G (BSPP) or NPT threads in place of the PT standard. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application before ordering.

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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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.

On an assembly bench where pneumatic clamps must close gently rather than at full line pressure, the low-pressure regulator section sets a reduced downstream pressure while the 40 um element keeps pipe scale and moisture out of the clamp cylinders.
Packaging and cartoning machines often run guide, hold-down and sorting cylinders at modest pressures. This unit filters the shop air and regulates it down for those circuits, with the check valve holding the setting during brief supply dips.
Bench test rigs and laboratory apparatus that need clean, low-pressure air benefit from the combination of particulate and water removal, a psi-scaled gauge for repeatable settings, and a 1/4 in NPT connection to standard rig tubing.
Start with the port step: size 200 with a 1/4 in NPT port suits compact circuits, and larger sizes (300/400/600) move up in port and flow capacity. Because this is the low-pressure (L) type, choose it where the regulated downstream pressure sits well below full line pressure; the exact regulation range for the low-pressure type is not published in our sheet, so confirm it with us against your setpoint. The differential-pressure drain is the default and needs no operator attention; a manual (M) or automatic (A) drain is available if your condensate load or duty cycle calls for it. The standard element is 40 um; specify W for the 5 um grade if downstream components need finer filtration. The fitted square gauge reads in psi; MPa or bar scales and an external round gauge are options. This unit has no mounting bracket (code J); brackets are optional on other variants. PT is the standard thread and G or NPT are order options - this code is specified with NPT. 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 the GFR series as curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your application and line conditions and we will confirm the relevant flow figures from the datasheet on request before you order.
The L in the code marks the low-pressure regulator type, intended for circuits where the regulated downstream pressure is well below full line pressure; the exact range for this type is not published in our sheet, so confirm it with us against your setpoint. Drainage is differential-pressure (the default): condensate collected in the bowl is bled off automatically as air flows through, with no manual draining required.
