The AirTAC GFR300C10JC1TK AirTAC Filter Regulator 3/8 in NPT 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 GFR300C10JC1TK is an AirTAC GFR300 filter regulator, a single-body unit that removes water and particulate from compressed air and regulates downstream pressure in one component. This size 300 configuration has a 3/8 in NPT port, the standard 40 um filter element, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and a fitted round pressure gauge scaled in MPa. A reverse/check valve is built in, and the unit is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with port options from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, an optional 5 um filter element (code W), square or round gauges with MPa, psi or bar scales, and G (BSPP) or NPT threads in place of the PT standard. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

Installed ahead of a directional-valve manifold on a machine's pneumatic circuit, it cleans the supply air and holds a steady set pressure so valve stations shift consistently through the shift.
Mounted at the drop to a packaging conveyor's pick-and-place cylinders, it strips water carried in from the compressor and regulates the pressure the cylinders see, protecting seals and stabilising stroke behaviour.
Fitted at a factory bench drop feeding air tools and blow-off guns, it removes condensate and pipe scale at the standard 40 um grade and lets the operator set a safe, repeatable working pressure on the MPa gauge.
Choose the size and port step against the air demand of the circuit: this size 300 unit carries a 3/8 in NPT port, and larger sizes move more flow at the same pressure. Because AirTAC publishes flow as curves rather than one rated number, send us your flow and pressure requirements and we will confirm the correct size from the datasheet before you order. This unit uses the standard 40 um filter element; specify the W variant if the application needs 5 um filtration. The differential-pressure drain is the default and suits continuous-flow lines; an automatic drain (code A) or manual drain (code M) can be ordered instead. The fitted round gauge reads in MPa; psi or bar scales and a square gauge are order options. Thread is NPT here; G (BSPP) is available, with PT as the catalogue standard. A mounting bracket can be added if the unit will not be piped rigidly.
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 rather than a single rated figure, so we do not quote one number. Tell us your required flow and working pressure and we will confirm the correct size and the curve data from the datasheet before you order.
K means a reverse/check valve is fitted, holding downstream pressure if the supply is interrupted. This unit also has the default differential-pressure drain, which discharges collected condensate automatically as air flows through - no manual draining needed in normal service. A manual (M) or automatic (A) drain can be ordered instead.
