The AirTAC GFR300C10LC1WT AirTAC Filter Regulator 3/8 in NPT 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 GFR300C10LC1WT is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 300 unit is fitted with a 3/8 in NPT port, a 5 um filter element (the W grade, finer than the standard 40 um), a differential-pressure drain that bleeds collected condensate whenever the pressure differential across the element rises, and a low-pressure regulator type. A round pressure gauge with an MPa scale is fitted, and a mounting bracket is included. No reverse/check valve is fitted.
This is a genuine AirTAC part from the GFR300 series. The GFR family is offered in sizes 200, 300, 400 and 600 with a choice of PT, G or NPT thread, manual, automatic or differential-pressure drain, 40 um or 5 um filtration, standard or low-pressure regulation, and square or round gauges in MPa, psi or bar scales. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

On a carton-sealing line where clamp cylinders must hold at a gentle, closely controlled pressure, this low-pressure filter regulator cleans the supply through its 5 um element and holds the set pressure to the clamp circuit, with the MPa round gauge giving the operator a clear setpoint reference.
Spray guns and atomising air on a finishing line are spoiled by water and fine dirt. Fed at the booth drop, this unit strips moisture and 5 um particulate from the compressed air and regulates the atomising pressure, while the differential-pressure drain keeps condensate moving out as the element loads.
Bottle-gripper and reject-gate cylinders on a filling line need clean, steady low-pressure air to handle containers without crushing them. This 3/8 in NPT unit conditions the drop feeding those actuators, and the included bracket lets it mount directly on the machine frame beside the manifold.
Start with the port: this unit steps up to 3/8 in NPT within the size 300 body, so match it to your downstream air demand and tubing. Choose the drain to suit attendance: the differential-pressure drain fitted here suits continuous-running lines, while automatic drain suits unattended duty and manual drain suits intermittent use. The 5 um element fitted here is the right choice where downstream valves and cylinders are sensitive to fine particulate; the standard 40 um element is the economical choice for general plant air. If your working pressure sits below the standard regulator band, the low-pressure type fitted here is the correct variant - its exact range is not published in our sheet, so confirm it with us. Gauge scale (MPa, psi or bar), thread (PT standard, G or NPT to order) and bracket are the remaining choices. 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 GFR series as curves, not as a single rated figure, so we do not quote a l/min or SCFM number. Tell us your application and we will confirm the flow figures from the datasheet so you can size the 3/8 in port correctly before ordering.
The GFR family is offered with a standard 40 um element or the finer 5 um grade, which the W code selects. The 5 um element fitted to this unit suits downstream valves, cylinders and tools that are sensitive to fine particulate; if your application runs on general plant air, the standard 40 um grade is the more economical choice.
