The AirTAC GFR30015AF2 AirTAC Filter Regulator PT1/2, Auto Drain 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 PT1/2" ports, a automatic 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 GFR30015AF2 is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the size 300 unit with a PT1/2 (1/2 in) PT thread port, 40 um standard filtration, an automatic drain that ejects collected condensate without manual attention, and a fitted embedded square gauge reading in psi. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing). The polycarbonate bowl suits this size, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, optional 5 um (code W) filtration, manual or differential-pressure drain alternatives, MPa/psi/bar gauge scales, and G or NPT thread options to order. Flow is published as curves rather than a single rated figure, 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 filtered, regulated air to impact drivers and nutrunners on a production line, with the automatic drain keeping condensate out of the tools during long unattended shifts and the psi gauge giving operators a clear set-point check.
Conditioning the air that drives conveyor stop-gate and pusher cylinders on a packaging line, where stable regulated pressure keeps stroke timing consistent and the 40 um element protects cylinder seals from particulate.
Supplying clean, regulated air to quarter-turn pneumatic valve actuators on a process skid, with the automatic drain handling condensate at the panel and the square psi gauge letting technicians verify the actuator supply set-point.
Choose the size and port step against the air demand of the circuit: this size 300 unit carries a PT1/2 (1/2 in) PT thread port, and larger sizes move more flow. This model already fixes three real choices: automatic drain (condensate is expelled without operator input - pick manual or differential-pressure drain if you prefer a different regime), 40 um standard filtration (specify the W variant for 5 um where finer particle capture matters), and a square gauge scaled in psi (MPa and bar scales, plus an external round gauge, are available). PT is the standard thread; G (BSPP) and NPT are order options. A mounting bracket is included.
Because flow is published as curves and not a single rating, we cannot quote one number here - send us your application details 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, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and datasheet figures for this size 300, PT1/2 unit on request before you order.
The A in the code GFR30015AF2 means the bowl drain is automatic: collected condensate is expelled without an operator opening the drain. The alternatives in this family are manual drain (code M, opened by hand) and the differential-pressure type (the default when no drain code appears). All three are orderable choices on the same GFR300 body.
