The AirTAC GFR300C15ALJC2WG 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 GFR300C15ALJC2WG is a filter regulator: one body that removes water and particulate from compressed air and holds the downstream pressure at a set point. This configuration is the GFR300 size with G1/2 ports, a 5 um filter element, an automatic drain that expels collected condensate on its own, a metal bowl, and a low-pressure regulator fitted with a round gauge reading in psi. It is supplied without a mounting bracket. Maximum working pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and offers a choice of drain type, 40 um or 5 um filtration, gauge style and scale, PT, G or NPT thread, and bracket options. 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.

Feeding clamping cylinders on a pneumatic press where the set point sits below the standard regulator range. The 5 um element keeps water and swarf out of the cylinder seals while the regulator holds the clamp pressure steady and the psi gauge shows the setting at the machine.
Conditioning air for diverters, pushers and gripper cylinders on a packaging conveyor. The automatic drain suits a unit mounted where an operator cannot reach the bowl each shift, and the round psi gauge gives a readable set point at the frame.
Supplying spray guns and air-driven agitators in a finishing booth, where the 5 um element strips water and particulate that would otherwise mark the coating, and the low-pressure regulator suits the lower set points spray equipment runs at.
Choose the size by the port and flow your line needs: this GFR300 carries G1/2 ports, above the 200 size at 1/4 inch and below the 400 and 600 sizes. Because rated flow is published only as curves, ask us to check the curve against your air consumption before you order. This configuration pairs a 5 um element (the 40 um standard element is the alternative) with an automatic drain, so it suits installations where nobody drains a bowl by hand; manual and differential-pressure drains are available elsewhere in the family.
The low-pressure regulator is intended for set points below the standard type's range; the exact range is not published, so confirm it with us. The round gauge here reads in psi, while embedded square gauges and MPa or bar scales are options. The thread on this unit is G; PT is the standard thread and NPT is an orderable option. No bracket is fitted with this code; brackets are available on other variants.
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 GFR300 flow as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, set point and air consumption and we will confirm the flow from the datasheet for this exact model before you order.
The A in the code selects the automatic drain: collected condensate is expelled without anyone opening the drain manually, which suits bowls mounted out of easy reach. Manual and differential-pressure drains are the other options across the GFR family. Drainage capacity figures are not published; ask us for the datasheet if you need them.
