The AirTAC GFR300C15AC2G AirTAC Filter Regulator, G1/2 Port 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 GFR300C15AC2G is a 300-size filter regulator that removes water and particulate from compressed air and holds downstream pressure in one body. This configuration is threaded G1/2 (1/2 in), carries a 40 um standard filter element, and drains condensate automatically, so the bowl empties itself during operation without manual attention. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), a round external gauge scaled in psi is fitted so the setpoint can be read directly, and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). No reverse/check valve is fitted on this variant.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, a 5 um (code W) element where finer filtration is needed, embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeding clean, regulated air to a pneumatically operated workshop press, where the automatic drain keeps condensate out of the valve stack and the psi gauge lets the setter dial in the working pressure.
Conditioning the air supply to conveyor-mounted packaging cylinders and clamps, combining water and particle removal with a stable regulated pressure for consistent cycle behaviour.
Installed at a machine drop point on a factory compressed-air ring main, filtering the general plant supply and regulating it to the pressure the machine was designed for.
Start with the port step: this unit is the 300 size at G1/2 (1/2 in); smaller 200 and larger 400/600 sizes exist, so match the size to the air demand of the circuit rather than the pipe alone. Drain choice matters: automatic drain (this unit) suits unattended duty, manual drain suits supervised installations, and differential-pressure drain is the catalogue default. Filtration is 40 um standard here; specify the W option for 5 um where finer protection is required. Gauge scale (MPa, psi or bar) and thread (PT standard, G or NPT to order) are decodable options, and a bracket can be included or omitted (code J).
Flow for this series is published as curves, not a single rated number, so we do not quote a rated flow figure. Send us your application details and we will confirm sizing against the datasheet curves 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 rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your application and air demand and we will confirm the sizing against the datasheet curves on request before you order.
The A in the code means the bowl drains condensate automatically during operation, which suits installations that run unattended. The GFR family is also available with manual drain or the differential-pressure drain as the catalogue default, and the 40 um element here can be swapped for a 5 um element (code W) where finer filtration is needed.
