The AirTAC GFR300C15ALC2W AirTAC Filter Regulator PT1/2 5 um 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 GFR300C15ALC2W is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is size 300 with a PT1/2 port, the 5 um filter element (the finer of the two published grades), an automatic drain that expels collected condensate without manual attention, and a round pressure gauge reading in psi. It is the low-pressure type, carries a polycarbonate (PC) bowl, and is rated for a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the G-series range, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch and PT, G(BSPP) or NPT threads. Flow for the series is published as curves rather than a single rated figure, 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.

Feeds spray guns and low-pressure atomising lines where the 5 um element helps protect finish quality and the low-pressure regulator holds a steady, gentle supply pressure to the booth.
Supplies and regulates low-pressure cylinders and air grippers on packaging and cartoning conveyors, with the automatic drain keeping condensate out of downstream valves.
Regulates hold-down and clamping pressure on light machining and assembly-cell fixtures, while the 5 um grade keeps fine debris away from sensitive control valves.
Choose the size and port step against the flow your line needs: this unit is size 300 with a 1/2 inch PT port, while G(BSPP) and NPT threads are order options. The 5 um element suits sensitive downstream equipment; a 40 um element is the standard alternative. The automatic drain handles condensate unattended, with manual and differential-pressure drains as the other published choices. The round gauge reads in psi, with embedded square gauges and MPa or bar scales available, and a mounting bracket is included. Because flow is published as curves, not a single rating, send us your flow and pressure requirements and we will confirm the right configuration 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 this series as curves, not a single rated figure, so we do not quote a number here. Send us your flow and pressure requirements and we will confirm sizing from the datasheet on request.
The W code in GFR300C15ALC2W selects the 5 um element, the finer of the two published grades, for applications with sensitive downstream equipment. The 40 um element is the standard choice and can be specified instead; we can confirm either option from the datasheet on request.
