The AirTAC GFR300C15LC2G 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 AirTAC GFR300C15LC2G is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This unit is built on the GFR300 size with G1/2 ports, the low-pressure regulator type, standard 40 um filtration and a differential-pressure drain that discharges collected condensate without manual intervention. The configuration is completed by a metal bowl, an included mounting bracket and a round psi gauge; no reverse/check valve is fitted.
This is a genuine AirTAC part from the GFR series, which spans sizes 200 to 600 with port sizes from 1/8 to 1 inch, plus manual and automatic drain options, a 5 um (code W) filter grade, gauge and thread choices, and standalone or combined layouts across the G-series. Rated inlet pressure for this unit is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). We confirm flow figures and the full datasheet on request, since flow is published as curves rather than a single rating.

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.

Filtered, low-pressure regulated air keeps workholding clamps on a machining centre at a steady, repeatable setting, with the 40 um element protecting the clamp cylinders from water and swarf carried in the shop supply.
On a bottling or cartoning line, this filter regulator feeds the air cylinders that push, divert and stop packs, combining water and particle removal with a stable low-pressure setting in one compact body.
Bench-scale automation in a laboratory - grippers, valves and small actuators - runs on a low-pressure regulated supply with a readable psi gauge, while the differential-pressure drain keeps condensate away from the instruments.
Choose the size step (200/300/400/600) against the flow your line needs - the 300 size here carries 1/2 inch ports. Where a bowl is fitted you can order differential-pressure drain (this unit), automatic drain (A) or manual drain (M), and the filter grade is 40 um as standard or 5 um with the W code. Regulated units carry a gauge - embedded square as standard, external round optional - with MPa, psi or bar scales, and the thread is PT as standard with G and NPT as order options; a bracket is included on this unit.
Because AirTAC publishes flow as curves rather than a single rated figure, we do not quote a flow number here. Send us your application details and we will confirm sizing and the datasheet figures 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 G-series flow as curves rather than a single rated figure, so we do not quote a flow number for this unit. Tell us your application - port size, downstream demand and working pressure - and we will confirm the sizing and flow figures from the datasheet on request.
The L code marks the low-pressure regulator type, intended for circuits that require reduced regulated pressure. The exact adjustment range for this low-pressure variant is not published in the material we hold, so we confirm it on request; the unit otherwise keeps the G1/2 ports, 40 um filtration, differential-pressure drain and round psi gauge decoded above.
