The AirTAC GFR300C15AC2WG AirTAC Filter Regulator G1/2 5 um 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 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 GFR300C15AC2WG is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in one body. This 300-size unit is threaded G1/2 (1/2 in), carries the finer 5 um filter element (code W, against the 40 um standard), drains condensate automatically, and is fitted with an external round gauge scaled in psi. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, a mounting bracket is included, and no reverse/check valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature 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 in, and can be ordered with manual or differential-pressure drains, 40 um or 5 um elements, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow for these units is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

Feeding clean, regulated air to workpiece clamps and tool-changer cylinders on a CNC machining cell, where the 5 um element protects fine valve spools and the round psi gauge lets setters verify clamp pressure at a glance.
Regulating air to stopper, reject and pusher cylinders on a bottling or carton conveyor line, with automatic drain keeping condensate out of the drop even when the line runs unattended across shifts.
Supplying filtered, regulated air to gripper and vacuum-generator circuits on pick-and-place robots, where stable downstream pressure keeps grip force repeatable and the included bracket simplifies panel mounting next to the valve manifold.
Choose the size and port against the air your line actually uses: this 300-size unit takes a 1/2 in port, and stepping up a size buys more flow capacity at the same function. Pick the drain to match attendance: automatic drain (this unit) suits drops nobody checks daily, manual drain suits supervised points, and differential-pressure drain is the catalogue default. Pick the element grade: 40 um is standard for general plant air, while the 5 um element fitted here (code W) suits finer downstream components. Gauges come as an embedded square gauge or an external round gauge (this unit) with MPa, psi or bar scales. Thread is PT as standard, with G and NPT available to order; a bracket is included on this unit. Flow is published as curves, not a single rating, so 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 curve and full datasheet figures for this 1/2 in unit before you order.
This unit drains collected condensate automatically, so it suits drops that are not checked daily. Manual-drain versions need an operator to open the drain, and differential-pressure drain is the catalogue default; the regulation range on this family stays 0.15-0.9 MPa (20-130 psi) across the drain choices.
