The AirTAC GFR300C10JC2TK AirTAC Filter Regulator, NPT3/8 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 GFR300C10JC2TK is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 3/8 in NPT port, the 40 um standard filter element, a differential-pressure drain, a round gauge reading in psi, and a reverse (check) valve fitted. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the regulation range with differential-pressure drain is 0.15-0.9 MPa (20-130 psi).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), an optional 5 um element (code W), gauge and thread options, and bracket choices. Flow is published as curves rather than a single rating, so ask us to confirm 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.

Clean, regulated air to the tool-change cylinders and clamping fixtures on a machining center, with the check valve helping hold the set pressure through supply dips.
Feeding the pushers, diverters and stopper cylinders on a packaging conveyor, where filtered, moisture-reduced air at a stable setting keeps repeat cycles consistent.
Point-of-use preparation for spray guns and air-assisted applicators in a finishing booth, removing water and particulate before the air reaches the gun.
Size 300 with a 3/8 in NPT port sits mid-range in the GFR line; step down to 200 or up to 400/600 depending on the air demand of your circuit - we confirm sizing against the published flow curves on request, since flow is not stated as a single rating. This unit keeps the 40 um standard element (5 um is available as code W where finer filtration is needed), the differential-pressure drain, a round psi gauge, and a fitted check valve that helps hold the downstream setting when upstream supply dips. The thread here is NPT; PT is the standard thread and G (BSPP) is a catalogue order option. No mounting bracket is included (code J).
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 this series as curves, not as a single rated figure, so we do not quote a number. Tell us your application and required flow and we will confirm the sizing against the datasheet curves on request before you order.
C is the round gauge option and 2 is the psi scale, so this unit carries an external round gauge reading in psi. The embedded square gauge is the standard fitting, with MPa, psi and bar scales available, and N in place of the gauge code would mean no gauge.
