The AirTAC GFR300C15JF3TK AirTAC Filter Regulator NPT 1/2 in 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 GFR300C15JF3TK is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 300 unit has 1/2 in NPT ports, the standard 40 um filtration grade, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough. The standard regulator covers a 0.15-0.9 MPa (20-130 psi) setting range, a square pressure gauge scaled in bar is fitted, and a reverse/check valve is built in to hold downstream settings if upstream supply is interrupted. No mounting bracket is included with this configuration.
This is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in and options including automatic or manual drains, a finer 5 um element, alternative gauge scales and G or NPT threads. Because flow is published as curves rather than a single rating, we confirm the datasheet and sizing 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.

Feeds filtered, pressure-controlled air to the tool-clamp and actuation circuits of a CNC machining centre, with the check valve holding the set pressure through supply dips.
Conditions the air feeding the pick-and-place and sealing cylinders on a carton packaging line, keeping water and debris out of the valves while holding a stable working pressure.
Sits at the drop to a spray booth or robotic paint cell, removing condensate and particles ahead of the regulator that sets the atomising and actuation pressure.
Choose the size and port step against the air demand of the circuit: this unit is size 300 with 1/2 in NPT ports, and the larger GFR sizes carry larger ports and more flow. Drain type is a real choice: differential-pressure (this unit) needs no attention, automatic drains continuously, and manual drains are emptied by hand - the manual-drain version also widens the regulation range down to 0.05 MPa. Filtration is 40 um standard; specify the W code for 5 um where finer protection is needed. The fitted square gauge reads in bar, with MPa and psi scales available, and an external round gauge is an option. Thread is NPT here, while PT is the catalogue standard and G (BSPP) can be ordered. Brackets are optional on this family.
Because flow is published as curves and not a single rated 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 rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the relevant datasheet flow figures and check the sizing for you before you order.
The differential-pressure drain on this configuration discharges collected condensate automatically when the pressure differential across the filter element rises, so it needs no manual attention under normal duty. Automatic and manual drains are also available in the GFR range - note that the manual-drain versions carry a wider regulation range down to 0.05 MPa (7 psi).
