The AirTAC GFR300C15JF2T 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 GFR300C15JF2T is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body, size 300 with 1/2 in NPT ports. This configuration carries the differential-pressure drain, a 40 um standard filter element, the standard regulator with a 0.15-0.9 MPa (20-130 psi) adjustment range, and the embedded square gauge scaled in psi. No mounting bracket is fitted and no reverse/check valve is included.
It is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and can be ordered with automatic or manual drain, a 5 um (W) element, MPa/psi/bar gauge scales, G (BSPP) or NPT threads, and bracket options. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing; the size 300 bowl is polycarbonate (PC). Flow is published as curves rather than a single rating, so ask us to confirm 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.

Feeding filtered, regulated air to the tool-change cylinders and workpiece clamps on a CNC machining centre, with the psi square gauge giving operators a direct read of the clamp circuit setting.
Conditioning the air feeding sealing jaws and pick-and-place cylinders on a packaging conveyor line, where the 40 um element keeps moisture and debris out of the valve stack.
Supplying filter-regulated air to pneumatic clamps and small presses in a manual assembly cell, holding a steady downstream pressure as stations cycle through the shift.
The real choices in this family are all decodable from the code. Step through sizes 200/300/400/600 to match the port and flow band your line needs - this unit is size 300 with 1/2 in NPT ports. Drain: differential-pressure as fitted here, automatic (A) or manual (M); note the manual-drain version widens the regulation range down to 0.05 MPa. Element: 40 um standard, or 5 um with code W. Gauge: the embedded square gauge here is scaled in psi, with MPa or bar scales and an external round gauge available. Thread: this unit is NPT; PT is the standard thread and G (BSPP) is an order option. Bracket: not fitted on this code (J), orderable otherwise.
One honest limit: AirTAC publishes flow as curves, not a single rated figure, so we do not quote a flow number. Send us your application and we will confirm sizing and 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, not a single rated figure, so we do not quote a flow number here. Tell us your application and we will confirm the flow curve and datasheet figures on request before you order.
The differential-pressure drain is the standard drain option on this GFR300 filter regulator: it opens to expel collected condensate as the pressure differential across the 40 um element builds. If you prefer a fully automatic drain, order the A version; the M version is manual, and its regulation range starts lower, at 0.05 MPa.
