The AirTAC GFR20008LJC2 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 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 GFR20008LJC2 is an AirTAC GFR200-series filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This 200-size unit carries 1/4 inch PT ports, the standard 40 um filter element, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure drop across the element is high enough. It is the low-pressure type, intended for circuits that work below the standard regulator band, and it is fitted with an external round gauge reading in psi. The polycarbonate bowl suits the -5 to 70 C (non-freezing) operating range, with a maximum inlet pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part, ordered here in the 200 size with 1/4 inch ports; the GFR family also spans 300, 400 and 600 sizes with larger ports, optional 5 um filtration (code W), automatic or manual drains, G or NPT threads, and gauge or bracket choices. Flow figures for this series are published as curves rather than a single rating, 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. 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.

On a carton-sealing or wrapping line where sealing bars and hold-down cylinders run at reduced pressure, this filter regulator cleans the shop air and holds the lower working pressure the mechanism was set up for.
For bench rigs and pilot rigs that need clean, gently regulated air to instruments, small actuators or purge lines, the 40 um element and low-pressure regulation keep the supply steady without over-pressurising sensitive kit.
Ahead of spray guns and air-assisted applicators in a paint or coating booth, this unit strips water and particulate from the compressed air and trims the supply down to the low pressure the gun is set for.
Start with the port step: the 200 size gives 1/4 inch PT ports, and stepping up to GFR300/400/600 buys larger ports and more flow capacity, so match the size to the air demand of the circuit rather than the pipe alone. Choose the drain: this unit has the differential-pressure drain as standard, while automatic (code A) and manual (code M) versions are available if your maintenance routine prefers them. The standard element is 40 um; specify W for the 5 um grade where downstream equipment needs finer filtration. This configuration is the low-pressure type, so it suits circuits held below the standard regulator band - ask us to confirm the exact adjustment range for your setpoint. Gauge scale here is psi; MPa and bar scales are alternatives. Thread is PT as standard, with G (BSPP) and NPT as orderable options, and this unit is ordered without a mounting bracket. Because flow is published as curves rather than a single rated figure, 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, not as a single rated number, so we do not quote a figure here. Tell us your application and required flow, and we will confirm the datasheet curve and check the 200-size unit is correctly sized before you order.
The C2 suffix orders the external round gauge with a psi scale (MPa and bar scales are alternatives). The L suffix makes it the low-pressure type, intended for circuits regulated below the standard band; its exact adjustment range is not in the published table, so ask us to confirm it against your setpoint.
