The AirTAC GFR30015F2TK AirTAC Filter Regulator 1/2 in NPT 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 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 GFR30015F2TK is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate from compressed air and holds a set downstream pressure, with no lubricator in this family. This configuration is the 300 size with a 1/2 in NPT port, the standard 40 um filter element, differential-pressure automatic draining of collected condensate, a fitted square pressure gauge reading in psi, a built-in check valve, and the mounting bracket included. The standard regulator adjusts outlet pressure in the range 0.15-0.9 MPa (20-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing. The bowl on this 300 size is PC (polycarbonate).
This is a genuine AirTAC part. The GFR filter-regulator line is available in sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT as standard thread and G or NPT as order options, manual or automatic drain choices, a 5 um element option (code W), and gauge scale choices. Flow is published as curves rather than a single rated figure, so ask us to confirm datasheet and flow figures for your application 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.

Feeding clean, pressure-set air to the cylinders and grippers on a carton-forming and sealing line, with condensate drained automatically so moisture never reaches the actuators.
Supplying filtered and regulated air to the clamping circuits of a CNC machining cell, where a stable set pressure keeps workholding consistent across the shift.
Conditioning the compressed air feeding lab automation and analytical instruments, removing water and 40 um particulate before it reaches sensitive pneumatic components.
Size and port are the first choice: 200, 300, 400 and 600 step up in port and flow capacity, and this unit is the 300 size with a 1/2 in NPT port, so match the next size up or down if your line uses a different port. Where a bowl is fitted you can choose differential-pressure draining (the default here, which bleeds condensate as pressure drop builds), fully automatic draining, or manual draining. Filter grade is 40 um standard or 5 um with code W; gauge scale is MPa, psi or bar, and this unit carries the square gauge in psi. Thread is PT as standard with G and NPT as order options, and the bracket is included. Flow for this family is published as curves rather than 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. The reflux valve permits reverse flow 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. Send us your application details and we will confirm the flow and datasheet figures for this 300 size, 1/2 in NPT unit on request.
This unit has the default differential-pressure drain: collected condensate is bled off as the pressure drop across the element builds, with no operator action. If you prefer, the same size is orderable with a fully automatic drain (code A) or a manual drain (code M), and the manual-drain variant widens the regulation range down to 0.05 MPa (7 psi).
