The AirTAC GFR300C10AF2W AirTAC Filter Regulator PT3/8, 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 AirTAC GFR300C10AF2W is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This unit is built in size 300 with a PT3/8 port, a 5 um filter element (code W), and an automatic drain that bleeds condensate from the polycarbonate bowl without operator attention. An embedded square gauge reading in psi is fitted, 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.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options across the family include manual or differential-pressure drains, the 40 um standard element, G (BSPP) or NPT threads, alternative gauge scales and an external round gauge. Rated flow is published as curves rather than a single figure, so ask us to confirm the datasheet and sizing 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 conditioning ahead of the main directional valve on a pneumatic press: the 5 um element catches water and particulate before they reach the valve, while the regulator holds a steady working pressure for consistent forming and stamping cycles.
Air preparation for cylinders and grippers on a packaging or bottling line. The automatic drain keeps condensate out of the supply during continuous shifts, and the psi gauge lets line technicians set and verify the working pressure at a glance.
Upstream conditioning for the air-driven functions of a CNC machining cell - tool clamping, chip ejection and purge air - where a filtered, regulated supply protects sensitive valves and cylinders from water and debris.
Choose the size and port against the air consumption of the downstream circuit: this configuration is size 300 with a PT3/8 port, and larger sizes carry larger ports and more flow. Drain type is a real choice - automatic (as fitted here) for hands-off condensate removal, manual for periodic draining, or differential-pressure as the default; note the regulation range is 0.05-0.9 MPa (7-130 psi) with a manual drain versus 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drains. Filter grade is 40 um standard or 5 um (this unit carries the 5 um W element) where finer particulate removal matters. Gauge scale can be MPa, psi or bar, and the thread can be ordered as PT (the standard), G (BSPP) or NPT. 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 rather than 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 datasheet figures for this unit on request, so you can size it against your actual air consumption before ordering.
This unit carries code A, an automatic drain that discharges condensate from the bowl without operator attention - useful on lines that run unattended. The same size 300 filter regulator can be ordered with a manual drain (code M) or the differential-pressure drain (no code). The regulation range differs slightly by drain: 0.05-0.9 MPa (7-130 psi) with a manual drain versus 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drains.
