The AirTAC GFR30015F2 AirTAC Filter Regulator PT1/2, 40 um, 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 GFR30015F2 is a 300-size filter regulator that removes water and particulate from compressed air and sets downstream pressure in one body. This configuration is threaded PT1/2 (1/2 in), carries the standard 40 um filter element, and drains condensate by differential pressure, so the bowl bleeds itself as the pressure differential across the element builds during normal running. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi) under a maximum inlet pressure of 1.0 MPa (145 psi), with an embedded square gauge fitted on a psi scale so the set pressure is visible at the unit. The polycarbonate bowl suits the -5 to 70 C (non-freezing) operating range, and the mounting bracket is included.
This is a genuine AirTAC part. The GFR family is available in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, and with choices of drain type (differential-pressure, automatic or manual), 5 um element (code W), gauge scale (MPa, psi or bar), G or NPT thread, and bracket or no bracket. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the datasheet 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.

On a CNC machining center, the GFR30015F2 conditions the supply feeding tool-clamp and pallet-lock cylinders, keeping chips and condensate out of the clamping valves while holding the clamp pressure the machine builder set on the psi gauge.
On a bottling or canning line, this unit feeds the diverter, stop-gate and pusher cylinders along the conveyor, filtering line-scale dirt and water from the header supply and regulating it to the pressure the gate actuators were set up for.
In a robotic spot-welding cell, the GFR30015F2 supplies the weld-gun clamping actuators with clean, regulated air from the cell drop, with the differential-pressure drain handling condensate from the long header run without daily manual draining.
Size the unit by the flow your line needs at the working pressure: the 300 size with its PT1/2 port sits in the middle of the GFR range, which steps from 200 (1/8-1/4 in) through 400 up to 600 (3/4-1 in). Choose the drain to match the duty: differential-pressure (this unit) drains itself under flow, automatic (code A) suits unattended installations, and manual (code M) suits dry, low-condensate air. The standard 40 um element protects most actuators and valves; specify 5 um (code W) where finer filtration is wanted. The square gauge is fitted here on a psi scale; MPa and bar scales and an external round gauge are alternatives. PT is the standard thread, with G (BSPP) and NPT available as order options, and the bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated figure, so we do not quote a flow number here. Send us your application details and we will confirm the datasheet figures against your required flow 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 family as curves rather than a single rated figure, so we do not state a flow number here. Tell us your working pressure and the flow your application needs, and we will confirm the datasheet curve figures for the GFR300 at PT1/2 on request before you order.
A blank drain code means the differential-pressure drain: the bowl bleeds condensate automatically as the pressure drop across the 40 um element builds during flow, so no daily manual draining is needed. If you prefer a positive automatic drain, order code A; if your air is dry and you want to drain by hand, code M is available. All three drain types share the same 0.15-0.9 MPa (20-130 psi) regulation range on this unit.
