The AirTAC GFR300C15LJC2WG AirTAC Filter Regulator G1/2 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 GFR300C15LJC2WG is an AirTAC GFR300 filter regulator: water and particulate filtration plus pressure regulation combined in a single body, with a metal bowl ahead of the regulator. This configuration is built around a G1/2 (BSPP) port - PT is the standard thread and G or NPT are order options - with a low-pressure regulator type, a 5 um filter element, a differential-pressure drain and an external round gauge reading in psi. No mounting bracket is fitted and no reverse/check valve is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part in the GFR300 size family. Across the G-series, filter regulators are offered in sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of 40 um standard or 5 um filtration, differential-pressure, automatic or manual drains, and gauge or no-gauge builds. Flow for this model is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures against 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 packaging and converting lines, glue or sealant heads often run at reduced pressure; this unit filters the supply to 5 um and lets the operator set a low regulated pressure at the point of use, with the round psi gauge giving a clear local reading.
Machine-shop fixture and clamp circuits need clean, steady air at a moderate setting; this filter regulator conditions the supply at the machine and provides a local gauge for setting the working pressure.
At a distribution take-off serving instruments or small actuators, the unit removes water and particulate downstream of the main line and regulates pressure locally, with the differential-pressure drain handling collected condensate.
The real choices on this family are decodable from the code. Step the size (200/300/400/600) and port (1/8 in to 1 in) against the flow your line needs; choose the drain type - differential-pressure as fitted here, automatic, or manual; pick the filter grade, 40 um standard or 5 um as on this unit; select the gauge type and scale (MPa, psi or bar); and specify the thread - PT is the standard, with G (BSPP) and NPT as order options. Brackets are optional. Because flow is published as curves rather than 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this series as curves rather than a single rated figure, so we do not quote a number here. Ask us to confirm the flow and the full datasheet figures against your application before ordering.
The L code marks the low-pressure regulator variant. The exact set-pressure range for this variant is not published, so we confirm it on request; the maximum inlet pressure remains 1.0 MPa (145 psi).
