The AirTAC GFR300C15JF1WT AirTAC Filter Regulator NPT1/2 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 AirTAC GFR300C15JF1WT is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in one body. This configuration is size GFR300 with a 1/2 in NPT port, fitted with the 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain that discharges accumulated condensate based on the pressure differential across the element, and an embedded square gauge scaled in MPa. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and a working temperature of -5 to 70 C (non-freezing). The bowl on the 300 size is polycarbonate, and no mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and catalogue options include manual or automatic drains, a 40 um standard element in place of the 5 um fitted here, an external round gauge with MPa, psi or bar scales, G (BSPP) or NPT threads instead of the PT standard, a reverse/check valve, and bracket choices. Flow is published as curves rather than a single rated 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.

A filter regulator ahead of the tool-clamp and chip-clearing cylinders on a CNC machining centre, with the 5 um element protecting the machine's fine pneumatic valves and the square gauge giving the operator a clear setpoint check.
Conditioning the air feeding the cylinder and gripper bank on a carton-forming packaging line, where the regulator holds a steady downstream pressure so sealing and forming strokes stay repeatable through the shift.
A filter regulator mounted ahead of a valve island on an assembly-line control panel, delivering clean, regulated air to the solenoid valves and keeping the gauge visible for quick line-side pressure verification.
Pick the size and port against the air demand of your circuit: GFR300 with a 1/2 in NPT port sits mid-range in the family, and larger sizes carry larger ports and more flow. Drain choices are differential-pressure (this unit), automatic, or manual - a manual drain also widens the regulation range down to 0.05 MPa. Filter grade is 40 um standard or 5 um (this unit, code W) where finer protection is needed. Gauges are the embedded square gauge (fitted here, MPa scale) or an optional external round gauge in MPa, psi or bar. Thread is PT as standard, with G (BSPP) and NPT (this unit) as order options, and a mounting bracket can be added if you need panel fixing. 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 family as curves, not as a single rated figure, so there is no one l/min or SCFM number we can quote honestly. Send us your application details - downstream demand and working pressure - and we will confirm the flow from the datasheet and check the sizing against your circuit before you order.
The W in the code GFR300C15JF1WT specifies the 5 um filter element, the finer of the two catalogue grades; the blank-code standard is 40 um. Both grades are catalogue options across the GFR family, so if coarse protection is enough for your line, the 40 um version of the same size and port can be ordered instead.
