The AirTAC GFR30015JF1TK AirTAC Filter Regulator NPT1/2 40 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 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 GFR30015JF1TK is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air, then holds the downstream pressure you set. This configuration has a 1/2 in NPT port, the standard 40 um filter element, a differential-pressure drain, an embedded square gauge reading in MPa, a reverse (check) valve fitted, and no mounting bracket. The polycarbonate bowl suits non-freezing compressed air from -5 to 70 C, with a maximum inlet pressure of 1.0 MPa (145 psi) and a regulation range of 0.15-0.9 MPa (20-130 psi).
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 options that include manual or automatic drains, a 5 um element (code W), an external round gauge with MPa, psi or bar scales, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

Point-of-use filter regulator feeding air cylinders and air tools on a factory assembly line, cleaning the supply and holding a set working pressure at each drop.
Conditioned, regulated air supply to directional control valves and actuators on packaging and bottling machinery, keeping water and debris out of the valve train.
Regulated air for diverters, stoppers and pusher cylinders along conveyor and sorting lines, with the 40 um element helping keep grit away from seals.
Within GFR300, the 1/2 in NPT port is the step for larger supply lines; move up or down a size when your air demand changes, and check the choice against the published flow curves. The drain can be differential-pressure (this model), automatic (code A) for unattended duty, or manual (code M) for scheduled bleeding. The element is 40 um standard, or 5 um (code W) where finer filtration is needed. The gauge here is the embedded square type reading in MPa; psi or bar scales and an external round gauge are options. Thread is NPT on this unit - PT is the standard and G (BSPP) is the alternative to order - and no bracket is fitted on this model. 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR300 as curves rather than a single rated figure, so we do not quote one number here. Send us your inlet pressure, set downstream pressure and expected air demand, and we will confirm the sizing from the datasheet on request.
The differential-pressure drain (standard on this model) bleeds the bowl when the pressure differential across the element rises as it loads with condensate. Choose automatic drain (code A) for unattended installations, or manual drain (code M) where an operator can drain the bowl on a schedule.
