The AirTAC GFR300C15JF2 AirTAC Filter Regulator PT1/2, 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 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 GFR300C15JF2 is an AirTAC GFR300 filter regulator: a single body that removes water and particulate from compressed air and holds downstream pressure at your setpoint. This size 300 unit is threaded PT1/2 (1/2 in), carries a 40 um filter element, drains condensate by differential pressure, and has an embedded square gauge reading in psi. The standard regulator covers 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The G-series filter regulator range spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, PT, G or NPT threads, 40 um standard or 5 um (code W) elements, differential-pressure, automatic or manual drains, and MPa, psi or bar gauge scales. Flow is published as curves rather than a single rating, so ask us to confirm figures from the datasheet 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.

Filtered, regulated air to a stamping or assembly press actuator line, keeping clamp cylinders at a steady setpoint downstream of the compressor receiver.
Supplying carton-sealing and diverting air cylinders on a packaging conveyor, with the 40 um element protecting directional valves from water and debris.
Conditioning shop air for tool-change clamps and air-powered fixtures on a CNC cell, holding a stable setpoint as demand cycles between stations.
Size and port set the air capacity: step up from 200 through 600 as your flow demand grows; this GFR300 is sized for 1/2 in PT piping. Choose the drain to match duty - differential-pressure (this unit), automatic for unattended condensate removal, or manual where you bleed by hand - and note the regulation range differs by drain type. Pick 40 um for general protection or 5 um (code W) for finer filtration, and select the gauge scale (MPa, psi or bar). PT is the standard thread; G and NPT are order options, and a mounting bracket can be added. Flow is published as curves, not a single rating - send us your flow and pressure requirements and we will confirm sizing from the datasheet before you order.
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 as curves rather than a single rated figure, so we do not quote a number here. Tell us your working pressure and air demand and we will confirm the flow from the datasheet on request.
This unit discharges collected condensate when the pressure differential across the bowl reaches a set level, so there is no manual bleeding in normal operation. If you prefer a fully automatic drain or a simple manual drain, those are separate order options; note the regulator adjustment range differs by drain type.
