The AirTAC GFR30015AF2TK AirTAC Filter Regulator NPT1/2 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 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 AirTAC GFR30015AF2TK is a GFR-series filter regulator: one body that removes water and particulate from compressed air and holds the downstream pressure at your setpoint. This unit is built in the 300 size with 1/2 in NPT ports, a 40 um filter element, an automatic drain that clears collected condensate without manual attention, an embedded square gauge reading in psi, and a built-in check (reverse-flow) valve. The polycarbonate bowl suits the 300 frame, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, thread options PT, G and NPT, drain choices (differential-pressure, automatic or manual), a 5 um element option (code W), gauge scale choices and low-pressure variants. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Rated flow is published as curves rather than a single figure, so ask us and we will confirm the datasheet 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.

Point-of-use filter regulator ahead of the solenoid valves on a CNC machining centre, keeping condensate and swarf-carried grit out of the valve stack while holding a steady setpoint to the tool changer and clamps.
Mounted at the air drop feeding the pneumatic cylinders on a carton-sealing conveyor, where the automatic drain handles overnight condensate build-up and the regulator keeps the flap and press cylinders at one consistent pressure.
On the supply line to a bench pneumatic press, the 40 um element protects the air cylinder and the built-in check valve holds the downstream setpoint if the shop supply dips momentarily.
Choose the size by the flow your line needs: 200, 300, 400 and 600 step up in port and capacity - here that is 300 with 1/2 in NPT ports. With the automatic drain fitted, the regulator setpoint range is 0.15-0.9 MPa (20-130 psi). Drain type is a real decision: automatic (this unit) expels condensate on its own, manual needs periodic draining, and the differential-pressure default triggers on a set pressure drop. The standard element is 40 um; specify code W for 5 um where finer filtration matters. The embedded square gauge reads psi here; MPa and bar scales and an external round gauge are order options. PT is the standard thread, with G and NPT as catalogue options, and a bracket is included. Because AirTAC publishes flow as curves rather than a single rating, send us your flow and pressure requirements 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR-series flow as curves rather than a single rated figure, so we do not quote one number here. Send us your flow and downstream pressure requirements and we will confirm the datasheet curve for this 300-size, NPT1/2 unit before you order.
The A in the code fits an automatic drain, which expels collected condensate without anyone opening the bowl - useful on lines that run unattended. Manual and differential-pressure drain versions exist in the same family, and the 40 um element can be specified as 5 um (code W) at order time.
