The AirTAC GFR30015F1WT AirTAC Filter Regulator NPT1/2 in is a genuine G-series filter regulator: water separation, 5 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 GFR300 series combines water and particulate filtration with downstream pressure regulation in a single body, so one unit cleans the air and holds a stable working pressure for the equipment it feeds. This GFR30015F1WT is the size 300 unit with a 1/2 in NPT port, the 5 um filter element (code W), a differential-pressure drain on the bowl, and a standard regulator adjustable from 0.15-0.9 MPa (20-130 psi). The embedded square gauge reads in MPa so the setting is visible at the wall, and the polycarbonate bowl is protected by a metal bowl guard. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). A mounting bracket is included.
This is a genuine AirTAC part supplied by an authorised distributor. The GFR family is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um (W) filtration, square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Rated flow is published only as curves, not a single figure, so ask us to confirm the datasheet and sizing for your application before ordering.

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 treatment on the drop feeding a CNC machine's tool-clamp and chip-ejection cylinders: 5 um filtration protects the machine's valves, and the regulator holds the clamp pressure the toolchanger was set up for.
Mounted ahead of the valve manifold on a carton-forming and sealing line, where clean, regulated air keeps sealing jaws and product-push cylinders cycling at a consistent set pressure through the shift.
Feeding the divert and stopper-gate cylinders on a distribution-centre conveyor: the 1/2 in port serves the larger gate actuators, the square MPa gauge lets maintenance verify set pressure at a glance, and the differential-pressure drain signals when the bowl needs attention.
Size 300 with a 1/2 in port sits in the middle of the GFR range; step up to 400 or 600, or down to 200, according to the flow your line needs - we will confirm the flow curves against your demand before you order. Drain comes as differential-pressure (this unit, standard), automatic (A) or manual (M); choose automatic where the unit is hard to reach, manual where you want controlled blowdown. Filtration is 5 um here (code W) against the 40 um standard element - pick 5 um where downstream valves and cylinders are finer-tolerance. The gauge is the embedded square type scaled in MPa; psi or bar scales and an external round gauge are order options. This unit is NPT; PT is the standard thread and G (BSPP) is also available to order. A mounting bracket is included, and the standard regulator type covers the 0.15-0.9 MPa (20-130 psi) setting range.
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 GFR300 flow only as curves, not as a single rated figure, so we do not quote one. Send us your line demand and working pressure and we will confirm the datasheet curves and check the sizing for you before you order.
The W in the code GFR30015F1WT selects the 5 um element in place of the 40 um standard. Choose 5 um where the downstream valves, cylinders or instruments have finer tolerances; the 40 um element remains available on other GFR300 variants if coarser, longer-interval filtration suits the line.
