The AirTAC GFR300C10LF2TK 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 GFR series combines a filter and a pressure regulator in a single body: compressed air is cleaned of water and particulate, then regulated downstream. This GFR300C10LF2TK is the 300 size with a 3/8 in NPT port, the standard 40 um filter element and a differential-pressure drain, and it is built as the low-pressure regulator type with an embedded square gauge reading in psi. A reverse/check valve is fitted and a mounting bracket is included. On this 300 size the bowl is polycarbonate (PC). 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 filter-regulator family is offered in 200, 300, 400 and 600 sizes with a choice of PT, G or NPT thread, 40 um standard or 5 um (code W) filtration, differential-pressure, automatic or manual drains, gauge scales in MPa, psi or bar, and standard or low-pressure regulator types. Flow is published as curves rather than a single rating, so ask us to confirm sizing and any datasheet figure against your application before ordering.

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.

Filtering and regulating the 3/8 in drop that feeds pneumatic clamps on an assembly fixture running at a low set pressure, with the reverse/check valve fitted as part of the circuit.
A point-of-use filter regulator on a packaging or bottling conveyor feeding small cylinders and diverters, where the 40 um element and differential-pressure drain keep the supply tidy without daily manual draining.
Built into an original-equipment air-preparation panel, where a compact filter regulator with a psi-scale square gauge and an included mounting bracket simplifies the install on the machine's 3/8 in air line.
When selecting within the GFR300 series, step size and port to the flow your line needs - this 300 size takes a 3/8 in port, and larger sizes carry more flow. Because flow is published as curves rather than a single rating, ask us to check the curve against your application before ordering. The remaining choices are all decodable from the code: drain type (differential-pressure as fitted here, or automatic or manual), filter grade (40 um standard, 5 um with code W), gauge scale (this unit reads psi; MPa and bar are available), thread (PT is the standard, while G and NPT are order options - this unit is NPT), bracket, and standard versus low-pressure regulator type. The exact adjustment range of the low-pressure type is not published in our data, so confirm your set pressure with us 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 GFR flow as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow curve and sizing from the datasheet on request.
This GFR300C10LF2TK is the low-pressure regulator variant of the GFR300. The exact adjustment range for the low-pressure type is not published in our data, so confirm your set pressure with us before ordering. Maximum inlet pressure is 1.0 MPa (145 psi) and the temperature range is -5 to 70 C.
