The AirTAC GFR300C15AF2T 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 GFR300C15AF2T is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in a single body. This configuration is built for 1/2 in NPT ports, filters to the standard 40 um grade, expels condensate through an automatic drain, and carries an embedded square gauge reading in psi. The regulator adjusts from 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and the polycarbonate bowl suits ambient temperatures of -5 to 70 C (non-freezing).
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 across the family include manual and differential-pressure drains, a 5 um filter element, alternative gauge scales, an external round gauge, G or NPT threads, and bracket choices. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet 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.

Feeding filtered, regulated air to CNC machining centers and their pneumatic clamps, where 40 um filtration keeps water and debris out of machine valves and steady regulation protects cycle consistency.
Supplying regulated air to pick-and-place cylinders and product diverters on a bottling or carton-packing line, with the automatic drain handling condensate through long production shifts.
Conditioning air for pneumatically actuated ball and butterfly valves on a process skid, where the local psi gauge gives operators a setpoint check and stable regulation protects the positioners.
Size and port come first: the GFR300 is the mid-size step of the family, and this unit is drilled for 1/2 in NPT ports - match the port to your line size and the flow your circuit needs. Drain type matters in service: this unit drains condensate automatically, while manual and differential-pressure drains are available elsewhere in the family. The 40 um element is the standard grade, with a 5 um (code W) element optional where finer filtration is required. The embedded square gauge here reads in psi, with MPa and bar scales as alternatives and an external round gauge optional. Thread on this unit is NPT, with PT (the standard) and G available to order, and 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 GFR300 flow as curves rather than a single rated figure, so we do not quote a number here. Tell us your line size and downstream demand and we will confirm the flow and full datasheet figures for GFR300C15AF2T on request.
This unit carries an automatic drain, which expels collected condensate from the bowl without daily attention; the GFR family also offers manual and differential-pressure drains. Note that the regulation range differs by drain type: automatic and differential-pressure drains give 0.15-0.9 MPa (20-130 psi), while manual-drain versions adjust from 0.05-0.9 MPa (7-130 psi).
