The AirTAC GFR300C15C2T 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 GFR300C15C2T is a size-300 filter regulator that cleans compressed air and holds downstream pressure in one body. It removes water and particulate through a 40 um element, drains collected condensate automatically by differential pressure, and regulates outlet pressure across 0.15-0.9 MPa (20-130 psi). This configuration is fitted with a round psi gauge, includes a mounting bracket, and has a 1/2 in NPT port for piped installations.
This is a genuine AirTAC part from the GFR300 series. The GFR line spans sizes 200, 300, 400 and 600, with port options in PT, G and NPT threads, manual, automatic or differential-pressure drains, an optional 5 um element, and MPa, psi or bar gauge scales. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing against your application and we will supply the datasheet 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.

Installed on the half-inch air drop feeding a CNC machining cell, it strips water and swarf-laden particulate from the mill's supply and holds a steady regulated pressure to the machine's pneumatic clamps and tool-changer cylinders.
Mounted where the plant air main branches to a carton-sealing and palletising line, it filters condensate out of the supply and regulates the pressure driving the conveyor's diverters, stoppers and case-erector cylinders.
Fitted at a bench-mounted pneumatic press station, it cleans the shop air feeding the press cylinder and lets the operator set and read the working pressure in psi on the round gauge.
Size 300 with a 1/2 in NPT port suits lines where a half-inch supply feeds the unit. Step up to size 400 or 600 for larger pipework, or down to 200 for compact circuits - match the size to the flow your circuit needs, and we will confirm the flow curve against your demand before you order. The standard 40 um element covers general plant air; choose the 5 um (W) option where finer protection is needed. The differential-pressure drain discharges condensate automatically as the pressure across the element rises, with no drain fitting to set. The round psi gauge is fitted as specified; MPa or bar scales are available. NPT is the thread for this code - PT and G are catalogue alternatives to order. A mounting bracket is included.
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 performance curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and the flow your circuit needs, and we will confirm the correct size from the datasheet on request before you order.
This unit uses the default differential-pressure drain: condensate collected in the bowl is discharged automatically when the pressure drop across the 40 um element rises, so there is no manual drain valve to operate. Manual (code M) and fully automatic (code A) drains are catalogue options if your installation prefers them.
