The AirTAC GFR300C15MF1WT AirTAC Filter Regulator NPT1/2 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 GFR300C15MF1WT is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 300 unit has a 1/2 in NPT port, a 5 um filter element, a manual drain on the bowl, and an embedded square gauge reading in MPa. The regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options across the series include automatic or manual drains, a 5 um element, square or round gauges with MPa, psi or bar scales, and a reverse/check valve. Flow is published as curves rather than a single rating, so ask us to confirm sizing figures from the datasheet 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.

Conditions and regulates the air feeding clamp and gripper actuators on a bottling line, holding a set downstream pressure while the 5 um element keeps contaminants out of the valves.
Sits at the feed to diverter-gate cylinders on a parcel sortation conveyor, giving operators a local pressure setting point and a square MPa gauge for line-side checks.
Provides point-of-use filtration and regulation for pneumatic valves on an automated sample-handling rig, where the 5 um grade protects sensitive pilot components.
Match the size and port to the air demand of the circuit: this unit is size 300 with a 1/2 in NPT port, sitting between the 3/8 in port step and the larger 400 series. Drain choice affects service routines: a manual drain like this one needs periodic bleeding by hand, while automatic and differential-pressure drains discharge condensate without operator attention. The 5 um element (code W) suits finer pneumatic components and instruments; the standard grade is 40 um. The embedded square gauge reads in MPa, with psi or bar scales and an external round gauge available as options. Thread here is NPT; PT is the standard thread and G (BSPP) is an order option, and a mounting bracket is included with this code.
Because rated flow is published as curves rather than a single 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. 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, not as a single rated figure, so we do not quote a number here. Tell us your working pressure and air demand and we will confirm the sizing from the datasheet on request.
This code carries a manual drain, so condensate in the bowl must be drained periodically by hand. AirTAC also offers automatic and differential-pressure drains on GFR units. Note that the regulation range quoted for manual-drain versions is 0.05-0.9 MPa (7-130 psi).
