The AirTAC GFR300C10LC1T AirTAC Filter Regulator NPT3/8 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 GFR300C10LC1T is a size 300 filter regulator: it removes water and particulate from compressed air and reduces pressure to your set point in a single compact body. This configuration has a 3/8 in NPT port, a 40 um standard filter element, and a differential-pressure drain that purges collected condensate automatically whenever the pressure differential across the bowl rises. The regulator is the low-pressure type, and a round pressure gauge with an MPa scale is fitted so you can read and adjust the downstream setting directly. A mounting bracket is included and no reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR300 series is one of four sizes (200, 300, 400, 600) spanning ports from 1/8 in to 1 in, with options including automatic or manual drains, a 5 um element (code W), gauge scales in MPa, psi or bar, and G or NPT threads in place of the PT standard. AirTAC publishes flow for this family as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application on request.

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.

Feeds the clamping circuit on a machining centre: the 40 um element strips water and swarf-laden condensate from the shop air, while the low-pressure regulator holds a reduced, stable setting for fixture clamps that must not be over-pressurised.
Sits at the drop point feeding diverter and stopper cylinders on a carton conveyor. The differential-pressure drain keeps condensate out of the valves during shift runs, and the fitted MPa gauge lets the line technician verify the actuation pressure at a glance.
Supplies the web-cleaning and sheet-separation jets of an offset press, where the low-pressure regulator type is chosen because the jets work at reduced set pressures. The 3/8 in NPT port matches the press manifold take-off and the bracket fixes the unit to the press frame.
Start with the port and size: this unit is size 300 with a 3/8 in NPT port, one step up from 1/4 in and one below 1/2 in, so size up if your line may need more flow later. Choose the drain to suit access: this unit uses the differential-pressure drain (purges on pressure change); automatic drain (code A) suits unattended positions and manual drain (code M) suits supervised ones. The 40 um element fitted here is the standard grade; specify 5 um (code W) if downstream equipment needs finer filtration. The fitted round gauge reads in MPa; psi or bar scales are available. This is the low-pressure regulator type, selected where the circuit works at lower set pressures - the exact adjustment range for this variant is not published, so confirm it with us. Threads: PT is the AirTAC standard and G (BSPP) or NPT are order options - this unit is built with NPT. A bracket is included. Because flow is published as curves rather than a single rating, 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 does not publish a single rated flow figure for this unit - flow is given as performance curves that depend on inlet pressure and set pressure. Tell us your operating pressures and we will confirm the relevant datasheet flow figures for your application on request before you order.
The L marks the low-pressure regulator type, selected for circuits that work at lower set pressures than the standard version. The exact adjustment range for this low-pressure variant is not published in the material we hold, so please confirm the range with us on request. The rest of the code decodes as: size 300, 3/8 in NPT port, differential-pressure drain, 40 um element, round gauge with MPa scale, bracket included, no check valve.
