The AirTAC GFR30015F2GK AirTAC Filter Regulator G1/2, psi Gauge 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 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 GFR30015F2GK is a size-300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a G1/2 (BSPP) port, the standard 40 um filter element, a differential-pressure drain that bleeds collected condensate automatically whenever the pressure drop across the element rises, and an embedded square gauge scaled in psi. A reverse/check valve is fitted, and the mounting bracket is included.
This is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, G, NPT or PT threads, 40 um or 5 um (W) filtration, automatic, manual or differential-pressure drains, and MPa, psi or bar gauge scales. Flow is published as curves rather than a single rating, so ask us to confirm the figures for your application on request.

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.

Mounted at the point of use on a factory air drop, it cleans water and swarf out of the supply and holds a steady, gauge-monitored pressure to the cell's actuators and air tools.
Feeding a machining centre's pneumatic circuit, it strips condensate and particles before clamps and tool-changer cylinders, with the check valve holding the set pressure if the main supply dips.
On a cartoning or wrapping line, it conditions the air and lets technicians dial in the exact working pressure for sealing jaws and gripper cylinders, read directly on the psi gauge.
Size 300 with a 1/2 in port sits in the middle of the GFR range; step up to size 400 or 600, or down to 200, according to the flow your line needs - we can check the published curves against your demand before you order. The differential-pressure drain on this unit needs no daily attention, but a manual-drain version is available if you prefer positive control, and an automatic drain (code A) for fully unattended bowls. The 40 um element suits general plant air; specify the W option for 5 um where finer pre-filtration matters. The fitted square gauge reads in psi; MPa or bar scales and an external round gauge are alternatives. PT is the standard thread and G (BSPP) or NPT are order options - this unit is the G-thread version. Brackets can be omitted (code J) if you mount differently.
Because flow is published as curves and not a single rated figure, ask us to confirm sizing against your application before ordering.
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 G-series flow as curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and the flow your equipment needs and we will confirm from the datasheet curves whether this 1/2 in, size-300 unit is correctly sized - just ask before ordering.
This unit's bowl uses a differential-pressure drain: condensate is discharged automatically whenever the pressure drop across the 40 um element rises, so there is no drain to operate daily. If your application suits a fully automatic float drain (code A) or a manual drain valve (code M), those variants can be ordered - ask us for the equivalent model.
