The AirTAC GFR300C15LF2WK 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 GFR300C15LF2WK is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is built on the size 300 frame with PT1/2 ports, a 5 um filter element (code W, versus the 40 um standard), a differential-pressure drain, and a metal bowl. The regulator is the low-pressure type (code L), intended where set pressures sit below the standard range; the exact adjustment range for this variant is not published, so we confirm it against the datasheet on request. A square pressure gauge scaled in psi is fitted, a reverse/check valve (code K) is built in, and the mounting bracket is included. Maximum working (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 family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options across drain type (differential-pressure, automatic, manual), filter grade (40 um standard, 5 um optional), gauge style and scale (MPa, psi or bar), thread (PT standard, with G and NPT as catalogue options), and bracket. Flow is published as curves rather than a single rated figure, so send us your application details and we will confirm sizing and datasheet figures on request.

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.

Filtered, low-pressure-regulated air to clamp cylinders on a machining-centre fixture line, with the 5 um element helping keep water and fine debris out of the clamp valves.
Supplying a carton-sealing conveyor station where seal and divert actuators run at reduced pressure; the differential-pressure drain and metal bowl manage condensate at the point of use.
A compact filter-regulator point for low-pressure gripper circuits on a robot cell, with the built-in check valve on board and the included bracket simplifying mounting beside the cell manifold.
Choose the size by the port and flow step: sizes 200, 300, 400 and 600 map to ports from 1/8 in to 1 in, and each step up carries more flow; this unit is size 300 with PT1/2. Pick the drain: differential-pressure (this unit), automatic (A) for unattended condensate removal, or manual (M) for periodic draining. Pick the element: 40 um standard or 5 um (W, this unit) for finer protection of downstream components. The embedded square gauge is standard with MPa, psi or bar scales (this unit: square, psi); an external round gauge is optional. Thread is PT as standard with G and NPT as catalogue options, and the bracket is included on this unit (code J deletes it). Because flow is published as curves rather than a single rating, 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 GFR300 series as curves, not as a single rated figure, so we do not quote a number. Send us your line pressure, set pressure and air demand, and we will confirm the flow from the datasheet on request.
It marks the low-pressure type regulator, intended for lower set pressures than the standard type. The exact adjustment range for this variant is not published, so we confirm it on request. The rest of the code decodes as: 15 = PT1/2 port, F2 = square gauge with psi scale, W = 5 um filter element, and K = built-in reverse/check valve.
