The AirTAC GFR300C10LC2 AirTAC Filter Regulator 3/8 PT 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 GFR300C10LC2 is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 300 unit has PT3/8 ports, the standard 40 um filter element, a differential-pressure drain that bleeds the bowl as air passes, and a low-pressure regulator fitted with an external round gauge reading in psi. A mounting bracket is included and no reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drains, an optional 5 um (W) element, square or round gauges in MPa, psi or bar scales, and PT, G or NPT thread options. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so ask us to confirm sizing figures from the datasheet for your application.

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 air to spray guns on a finishing booth: the 40 um element keeps moisture and grit out of the finish, while the round psi gauge lets an operator set and verify gun supply pressure at a glance.
A clean, regulated air drop for a lab or test bench where instruments need low-pressure air; the psi gauge gives a direct local read and the differential-pressure drain keeps the bowl clear without daily attention.
Regulated low-pressure air to sealing or tucking heads on a packaging conveyor, with the 40 um element protecting downstream valves from water and debris carried in the shop air line.
Pick the size and port step against the flow your line needs: this size 300 unit with PT3/8 ports sits mid-range in the GFR family between the 200 and 400 units. The 40 um element is the standard filtration grade (the W code gives 5 um where finer filtration is required), and the differential-pressure drain keeps the bowl clear without a manual drain valve to attend. The L in the code selects the low-pressure regulator type, intended where controlled pressures sit below the standard range - the exact adjustment range is not published, so we confirm it on request. The round gauge reads in psi for a direct local indication; embedded square gauges in MPa, psi or bar scales are the alternative. Thread is PT as standard, with G (BSPP) and NPT available as order options, and the included bracket simplifies panel or frame mounting.
Because AirTAC publishes flow only as curves, not a single rated figure, send us your flow and pressure requirements 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 GFR300 flow as performance curves rather than a single rated number, so we do not quote a figure here. Send us your required flow and working pressure and we will confirm sizing from the datasheet for this unit before you order.
The L in the code selects the low-pressure regulator type, intended where controlled pressures sit below the standard range; the exact adjustment range is not published, so we confirm it on request. The C2 code fits the external round gauge with a psi scale - the embedded square gauge in MPa, psi or bar scales is the alternative if you prefer metric or a panel-integrated read.
