The AirTAC GFR300C15JF2WK AirTAC Filter Regulator PT1/2, 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 GFR300C15JF2WK is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in a single body, sized for 1/2 in PT ports. This configuration carries the W-grade 5 um filter element (tighter than the 40 um standard), a differential-pressure drain that bleeds collected condensate automatically as flow passes through, an embedded square gauge reading in psi, a built-in reverse (check) valve, and the standard regulator type with a 0.15-0.9 MPa (20-130 psi) adjustment range. The polycarbonate bowl suits non-freezing compressed-air service from -5 to 70 C, with a maximum inlet pressure of 1.0 MPa (145 psi). 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 port options from 1/8 to 1 in, manual or automatic drain alternatives, 40 um or 5 um filtration, MPa, psi or bar gauge scales, and G (BSPP) or NPT thread variants to order. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

Feeds clean, regulated air to tool changers, clamps and spindle-seal circuits on a machining centre, with the 5 um element guarding fine-tolerance pneumatic components from particulate carryover.
Sits at the drop point of a carton-forming and sealing conveyor, filtering condensate from the compressed-air main and holding steady pressure to the sealing cylinders for consistent flap tuck and tape actuation.
Conditions the air feeding pipetting heads and sample-transfer actuators on an analytical or diagnostic instrument, where the 5 um grade and a psi-reading gauge support repeatable, closely watched air supply.
Step up or down through the GFR sizes (200/300/400/600) to match the port and flow path your line needs; this 300 unit sits at 1/2 in PT. Choose the drain to suit access: differential-pressure (as here) where automatic bleeding is fine, automatic where you want positive discharge, or manual where an operator drains on schedule. Pick 40 um for general air drying ahead of cylinders and valves, or the 5 um W grade, as on this model, for finer protection of sensitive components. Gauge scale (MPa, psi or bar), thread (PT standard, G or NPT to order) and bracket inclusion are all decodable choices.
Because AirTAC publishes flow only as curves, not a single rated figure, we cannot quote a rated flow number here. Send us your application details and we will confirm the 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 GFR300 series as curves rather than a single rated figure, so we do not quote a rated flow number. Tell us your application and we will confirm the relevant flow and datasheet figures on request before you order.
W is the filter-grade code: this unit carries the optional 5 um element instead of the 40 um standard. Drain is the differential-pressure type (the default), which bleeds collected condensate as air flows through; automatic (A) and manual (M) drain versions are available in the same series.
