The AirTAC GFR300C15LF3TK AirTAC Filter Regulator NPT1/2 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 GFR300C15LF3TK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body, with a drain bowl but no lubricator. This 300-size unit has 1/2 in NPT ports, a 40 um standard filter element and a differential-pressure drain. It is the low-pressure (L) type regulator, fitted with an embedded square gauge reading in bar, a reverse (check) valve and a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is published in 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in, and with manual, automatic or differential-pressure drains, 40 um or 5 um (W) elements, square or round gauges scaled in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Filtered, regulated air at a reduced set pressure for grippers and end-of-arm tooling on assembly robots; the one-body filter regulator keeps the air-preparation footprint small and the square gauge gives a local bar reading at the cell.
Removes water and particles ahead of the directional valves on sorting, diverting and clamping cylinders along a packaging conveyor, while holding the supply at the set pressure the line was built around.
A compact filter-regulator station for the air-preparation section of injection molding and press control panels; this unit includes a reverse (check) valve and a mounting bracket for tidy panel installation.
Choose the size and port against your air demand: this 300-size unit has 1/2 in NPT ports, and the 400 and 600 sizes step up in port and flow. Drain type is a real choice on GFR units - differential-pressure (this unit), automatic (A) or manual (M) - and the filter element is 40 um standard or 5 um with code W. This is the low-pressure (L) regulator type; its adjustment range is not published, so confirm the set range with us (standard-type GFR units with differential-pressure drain adjust 0.15-0.9 MPa / 20-130 psi). The embedded square gauge on this unit reads in bar; MPa and psi scales and an external round gauge are options. PT is the AirTAC standard thread and G (BSPP) and NPT are order options - this unit is the NPT version. Bowls on 200/300/400 sizes are polycarbonate (PC); size 600 uses aluminium alloy. A mounting bracket is included. Flow is published as curves, not a single rating, so 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 number, so we do not quote a l/min or SCFM figure. Tell us your line pressure, set pressure and air demand and we will confirm the sizing from the datasheet on request.
This unit is the low-pressure version of the GFR300 regulator, intended for circuits that run at reduced set pressures. The adjustment range for the L type is not published in our sheet, so we confirm it on request; standard-type GFR units with differential-pressure drain adjust 0.15-0.9 MPa (20-130 psi).
