The AirTAC GFR300C10JC2K AirTAC Filter Regulator PT3/8, 40 um, psi 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 GFR300C10JC2K is a filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single body. This size 300 unit is threaded PT3/8 and carries a 40 um filter element with a differential-pressure drain that bleeds collected condensate automatically whenever the pressure drop across the element is high enough. The fitted round gauge reads in psi, a reverse/check valve holds downstream pressure when the supply is interrupted, and the unit ships without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl suits this 300 size.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, an optional 5 um element (code W), embedded square or external round gauges with MPa, psi or bar scales, G or NPT thread options, and an optional bracket. Flow is published as curves rather than a single rating, so ask us to confirm sizing and any datasheet figure against 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.

Point-of-use conditioning ahead of pneumatic clamps, tool-change cylinders and chip-clearing jets on a CNC machining centre: clean, regulated air at the set pressure the machine builder specifies, with the check valve holding the clamp circuit if shop air drops.
Supplying filtered, regulated air to the cylinders and air jets of a carton sealer or case-packing conveyor, where water and scale from the plant ring would otherwise stick valves and upset cylinder cycling at the set pressure.
A filter regulator mounted at the drop feeding a small pneumatic press or workholding fixture, keeping moisture and particulate out of the directional valve while the psi gauge lets the setter dial in and verify the working pressure.
Choose the size step (200/300/400/600) and its port to match the air demand of the circuit - larger sizes carry larger ports and more flow capacity. This unit is the 300 size with a PT3/8 port. Pick the drain to suit service: differential-pressure (this configuration) drains on pressure drop, automatic drains on a timer-free cycle, and manual drains need operator attention. The standard 40 um element suits general plant air; specify the 5 um W option where finer filtration is needed. Gauge scale is selectable (MPa, psi or bar - this unit is psi), and thread is PT as standard with G (BSPP) and NPT as order options. A bracket is optional (not fitted here). Flow for the series is published as curves, not a single rating, so send us your flow requirement and we will confirm the right size from 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 curves, not as a single rated figure, so we do not quote a number here. Tell us your flow demand and working pressure and we will confirm from the datasheet whether this 300 size with its PT3/8 port suits your application before you order.
K means a reverse/check valve is fitted: it holds downstream pressure if the upstream supply is interrupted. The C2 code specifies the external round gauge with a psi scale; MPa and bar scales are available as order options, and the embedded square gauge remains the standard alternative.
