The AirTAC GFR300C15AJC2GK AirTAC Filter Regulator G1/2 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 GFR300C15AJC2GK is a filter regulator: it removes water and particulate from compressed air and holds the downstream pressure at your setpoint, all in one body. This configuration has G1/2 ports, a 40 um filter element, an automatic drain that ejects collected condensate without operator attention, a round psi gauge, and a reverse/check valve fitted. The standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C (non-freezing). The bowl on the 300 size is polycarbonate.
This is a genuine AirTAC part. The GFR family is made in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and the catalogue options include manual or differential-pressure drains, a 5 um element (code W), the embedded square gauge or an external round gauge in MPa, psi or bar scales, G or NPT threads, and a mounting bracket (this unit is ordered without one). 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.

Fitted on the drop ahead of a CNC machining cell, it filters water and particles from the shop air to 40 um and holds a steady setpoint to the tool changer and clamps, with the automatic drain handling condensate through unattended shifts.
On a paint or coating line it conditions the air feeding spray guns and atomising valves, removing water and particulate and regulating pressure to the guns, while the round psi gauge gives operators a direct readout at the line.
Installed ahead of the valve manifold on a packaging conveyor, it protects cylinders and pick-and-place actuators from water and debris while keeping their working pressure stable through the shift.
Choose the size and port step against the flow your line needs: sizes 200, 300, 400 and 600 cover 1/8 to 1 inch ports, and this 300 unit sits at G1/2. Drain type is a real decision: automatic (this unit) suits unattended duty, manual drain needs an operator, and the differential-pressure default drains on a pressure drop. Filter grade is 40 um standard or 5 um with code W if downstream equipment needs finer air. Gauges come as the embedded square type or an external round gauge in MPa, psi or bar scales; this unit carries a round psi gauge. Thread is PT as standard with G (BSPP) and NPT as order options, and brackets are optional - this unit is ordered without one. Because flow is published as curves rather than a single rating, send us your application 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 GFR series as curves rather than a single rated figure, so we do not quote a number here. Send us your operating pressure and air demand and we will confirm the flow from the datasheet for this exact model before you order.
This unit carries code A, an automatic drain that ejects collected condensate on its own, which suits duty that runs unattended. The same GFR300 size is also available with a manual drain or the differential-pressure default, and with a 5 um element (code W) if you need finer filtration - tell us the variant and we will confirm it.
