The AirTAC AirTAC GFR300C10JF2K Filter Regulator 3/8 in PT 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 AirTAC GFR300C10JF2K is a 300-size filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a PT3/8 in port, the standard 40 um filter element, a differential-pressure drain that bleeds collected condensate whenever the pressure differential across the element is high enough, an embedded square gauge reading in psi, and a reverse (check) valve fitted. The pressure setting is adjusted across 0.15-0.9 MPa (20-130 psi), and the unit is supplied without a mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, an optional 5 um element (code W), gauge scale choices, and G or NPT thread variants orderable in place of the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application on request.

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.

Installed ahead of the pneumatic cylinders that drive filler heads and capping heads on a bottling line, cleaning the plant air of water and grit and holding a steady regulated pressure so each bottle cycle repeats consistently.
Feeding the air cylinders that kick cartons between conveyor lanes in a distribution centre, with the check valve holding the set pressure against backflow and the psi gauge giving operators a visible setpoint.
Conditioning and regulating the compressed air feeding bench-top test rigs and fixture clamps in an R&D lab, where the 40 um element protects sensitive instruments and the psi gauge allows repeatable pressure setups.
Start with the port step: this model is the 300 size at PT3/8 in, so step up to 400 or 600 if your line runs larger ports, or down to 200 if you want a compact point-of-use unit. Choose the drain to match access: differential-pressure drain (this model) needs no attention at set intervals, automatic drain empties the bowl continuously, and manual drain suits stations an operator visits anyway. The 40 um element is the standard grade; specify the 5 um W variant if downstream equipment needs finer filtration. The fitted square gauge reads in psi, with MPa or bar scales and an external round gauge available as options in the series. PT is the standard thread here; G (BSPP) and NPT versions can be ordered. This unit ships without a bracket, so plan your mounting plate accordingly. Flow is published as curves, not a single rating, so send us your flow and pressure requirements and we will confirm sizing against 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 GFR series as performance curves, not as a single rated number, so we do not quote a l/min or SCFM figure. Send us your required flow and working pressure and we will confirm the sizing against the datasheet on request before you order.
The K in the code means a reverse (check) valve is fitted, which prevents downstream pressure from pushing back through the unit, and the J means no mounting bracket is supplied, so the unit should be mounted on your own plate or manifold. Both are standard decodable options in the GFR series.
