The AirTAC AirTAC GFR300C15F2WG Filter Regulator, G1/2, 5 um 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 GFR300C15F2WG is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds a regulated downstream pressure in a single body. This configuration is sized GFR300 with a G1/2 (BSPP) port, carries the fine 5 um filter element (the standard element is 40 um; the W in the code selects 5 um), and uses the differential-pressure drain, which bleeds collected condensate automatically as air flows through the unit. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, an embedded square gauge reading in psi is fitted, and a mounting bracket is included. No reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR range is made in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options across the range include manual or automatic drains, the 5 um element, gauge scales in MPa, psi or bar, G or NPT threads in place of the PT standard, and low-pressure or check-valve variants. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing; the size 300 bowl is polycarbonate (PC). AirTAC publishes flow data as curves rather than a single rating, so ask us to confirm flow and 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.

Filtered, regulated air for the cylinder and gripper circuits on a beverage bottling line, with the 5 um element protecting downstream seals and valve seats from particulate and water carryover.
Stable regulated pressure for the tool-clamp and unclamp circuit on a CNC machining center, with the square psi gauge giving a direct setpoint check at the machine.
Regulated air for diverter gates and stopper cylinders on a distribution conveyor, with the differential-pressure drain handling collected condensate without interrupting the line.
Choose the size by port and required flow: GFR200 through GFR600 step up in port from 1/8 to 1 inch, and the right size is the one whose flow curve covers your demand at your working pressure - we can check that against the datasheet before you order. Drain choice is differential-pressure (fitted here, self-bleeding with flow), automatic (A) or manual (M); the 5 um element in this unit is the finer option where downstream instruments, valves or seals need cleaner air than the 40 um standard. The square gauge fitted here reads in psi; MPa and bar scales are the alternatives, and an external round gauge is optional. The trailing G gives G (BSPP) parallel threads - PT is the standard thread form in the range and NPT is available to order. A mounting bracket is included. Because flow is published as curves rather than a single rating, 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. 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 GFR300 as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure, downstream air demand and acceptable pressure drop, and we will confirm sizing against the datasheet before you order.
It specifies G (BSPP) parallel threads on this unit. PT is the standard thread form across the GFR range, and NPT is also available as an order option - tell us which thread your piping uses when you request a quote.
