The AirTAC GFR300C15F2T AirTAC Filter Regulator NPT1/2 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 GFR300C15F2T is a 300-size filter regulator that removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration has 1/2 in NPT ports, the standard 40 um filter element, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and a fitted embedded square gauge reading in psi. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). A mounting bracket is included; no reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with a choice of PT, G (BSPP) or NPT threads, manual or automatic drain in place of the differential-pressure default, a 5 um element (code W) in place of the 40 um standard, gauge scale options, and a low-pressure regulator type. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for 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.

Installed ahead of a CNC machine's pneumatic circuit, the GFR300C15F2T strips water and swarf-laden particulate from the shop air line and holds a steady regulated pressure for tool clamping and actuator circuits on a 1/2 in NPT drop.
On a carton-forming and sealing line, the unit conditions the plant air feeding cylinder-driven folding arms and sealing jaws, with the psi square gauge letting operators check set pressure at a glance during changeover.
Fitted at the feed of a sorting conveyor's pusher and stopper valves, the filter regulator cleans the compressed air and sets the working pressure the divertor cylinders were designed for, with the differential-pressure drain keeping condensate moving out during production runs.
Start with the port step: the 300 size carries 1/2 in ports here, and moving up or down a size changes both the connection and the flow path, so match the size to the air demand of the circuit rather than fitting the largest unit available. Choose the drain to suit attendance: differential-pressure drains only while air flows, automatic drains on a cycle, and manual drains need someone to open them. Pick 40 um for general plant air or the 5 um W element where downstream equipment needs finer filtration. Set the gauge scale to psi (as supplied here), MPa or bar, and confirm the thread: PT is the standard, with G (BSPP) and NPT as order options - this unit is supplied with NPT. A bracket is included for panel or surface fixing.
Because flow is published as curves and not a single rated figure, send us your application details 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 flow for the GFR300 series as curves, not as a single rated number, so there is no one figure we can honestly quote. Send us your line pressure, downstream demand and acceptable pressure drop, and we will confirm the sizing from the datasheet curves before you order.
The trailing T in GFR300C15F2T specifies NPT (1/2 in here), which suits US pipework. PT is the catalogue standard thread and G (BSPP) is also available as an order option across the GFR range - specify the suffix you need when ordering, as the thread is a specification choice, not a fitting we change after purchase.
