The AirTAC GFR300C08JC2GK AirTAC Filter Regulator, G1/4 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 GFR300C08JC2GK is an AirTAC GFR300 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is sized for a G1/4 (1/4 in) port with G thread, carries the standard 40 um filter element, and drains its PC (polycarbonate) bowl by differential pressure, so condensate is expelled as the pressure difference across the unit builds - no routine draining. A round gauge reading in psi is fitted, a reverse (check) valve is included, and no mounting bracket is supplied.
This is a genuine AirTAC part. The GFR family runs from size 200 to 600 with ports from 1/8 in to 1 in, with 5 um (W) elements, automatic or manual drains, alternative gauge scales, and PT, G or NPT threads as catalogue options. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. 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.

Filter and regulate the supply to a pneumatic press or clamping-cylinder circuit, keeping water and particulate out of the cylinder seals while holding a set working pressure.
Condition the air feeding the stopper, pusher and lift cylinders on a packaging conveyor, with the fitted check valve holding downstream pressure if the supply dips.
Supply filtered, regulated air to pneumatic ball or butterfly valve actuators on a process skid, with the local psi gauge giving operators a set-point reading at the unit.
Choose the size step first: 200, 300, 400 or 600, each with its own port range from 1/8 in to 1 in, matched to the air demand of your circuit - we confirm exact flow from the datasheet curves on request, since no single rated figure is published. On this 300-size unit the drain is differential-pressure; automatic (A) and manual (M) drain versions are available if you prefer a different draining regime. The filter grade here is the standard 40 um; specify W for the 5 um element where finer particulate capture matters. The fitted gauge reads in psi; the embedded square gauge and MPa or bar scales are the other catalogue choices. Thread is G on this model; PT is the standard thread and G and NPT are order options. Brackets are optional, and this configuration omits it.
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 as 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 before you order.
On this model the bowl expels condensate automatically as the pressure difference across the unit builds - no routine intervention. The catalogue also lists automatic (A) and manual (M) drain versions; note the regulation range differs by drain type, with the differential-pressure version adjusting 0.15-0.9 MPa (20-130 psi).
