The AirTAC GFR300C10ALC1WT 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 GFR300C10ALC1WT is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and then regulates the downstream pressure. This configuration is the low-pressure type with a 3/8 in NPT port, a fine 5 um filter element, and an automatic drain that ejects collected condensate without operator attention. A round MPa gauge is fitted so the regulated setting can be checked at a glance, and a mounting bracket is included for secure installation. 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. The GFR family is made in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, a choice of 40 um standard or 5 um filtration, differential-pressure, automatic or manual drains, and square or round gauges with MPa, psi or bar scales. Flow is published as curves rather than a single rated figure, so ask us to confirm flow and 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.

Conditioning the supply to the cylinders and actuated guides on a packaging line: the 5 um element keeps contamination out of directional valves while the low-pressure regulator holds a gentle setting for delicate product-handling motions, and the automatic drain keeps condensate out of the circuit through long production runs.
Feeding stopper, pusher and diverter cylinders on a conveyor system where a stable, low regulated pressure prevents product damage at the gate, the round MPa gauge lets line staff verify the setting at a glance, and the included bracket simplifies mounting beside the conveyor frame.
Point-of-use conditioning for lab benches and analytical instruments that need clean, moisture-free compressed air at a low, steady pressure; the 5 um filtration and automatic drain protect sensitive equipment, while the low-pressure regulator type matches the modest working pressures such instruments require.
Size and port step up with required flow: this unit is size 300 with a 3/8 in NPT port; choose size 200 for smaller lines or 400/600 for larger ones, and order PT or G thread if NPT does not match your pipework. Drain type matters in practice: the automatic drain here discharges condensate on its own, while manual and differential-pressure drains suit attended or air-saving installations. The 5 um element (code W) is finer than the 40 um standard, so pick it when downstream valves and cylinders need cleaner air. The fitted round gauge reads in MPa; psi and bar scales are also available, and the embedded square gauge is the standard alternative. This is the low-pressure regulator type for applications that call for settings below the standard range - because the exact low-pressure regulation range is not published, confirm it with us against your setpoint. Flow is published as curves, not a single rating, so 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 the GFR300 as curves, not as a single rated figure, so we do not quote a number here. Tell us your inlet pressure and downstream air demand and we will confirm the flow and datasheet figures for this exact model on request before you order.
The A code in this model means an automatic drain: condensate collected in the bowl is discharged without operator attention, which suits unattended installations. The GFR300 is also offered with a manual drain, or with the differential-pressure drain that is the family default, so you can order the type that fits the way your system is run.
