The AirTAC GFR300C10C1TK 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 GFR300C10C1TK is an AirTAC GFR300 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is a 300-size unit with a 3/8 in NPT port, a 40 um filter element and the differential-pressure drain as its default condensate handling. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) setting range under a 1.0 MPa (145 psi) maximum inlet, an external round MPa gauge is fitted so the downstream setting can be read directly, and a reverse/check valve is included. The polycarbonate bowl is rated for non-freezing compressed air from -5 to 70 C, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans the 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, and the same body can be ordered with a 5 um element (code W), automatic or manual drains, an embedded square or external round gauge in MPa, psi or bar scale, G (BSPP) or NPT threads in place of the PT standard, and with or without the bracket. Flow is published as curves rather than a single rated figure, 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.

Point-of-use air preparation for the cylinders and grippers on a bottling line: the 40 um element strips water and pipe scale while the regulator holds a steady downstream setting, and the round MPa gauge lets operators verify line pressure at a glance.
Feeds the air cylinders that divert, stop and align cartons on a distribution conveyor. The built-in reverse/check valve helps hold the regulator setting if upstream supply dips, and the 3/8 in NPT port suits typical drop piping at the line.
Supplies filtered, regulated air to pneumatic valves and instruments on a pilot-plant skid, where combining the filter and regulator in one body keeps the panel layout simple and the included bracket simplifies mounting inside the enclosure.
Within the G-series, step through the 200/300/400/600 sizes - each step moves the port from 1/8 in up to 1 in and with it the flow capacity shown in the catalogue curves - and match the thread to your piping: this unit is 3/8 in NPT, while PT is the standard thread and G (BSPP) and NPT are catalogue options. Choose the drain to suit maintenance practice: differential-pressure (as fitted here), automatic (A) for unattended condensate handling, or manual (M) for scheduled checks. Pick the element grade - 40 um standard or 5 um (W) where finer particulate protection matters - and the gauge: embedded square or external round, in MPa, psi or bar scale. The bracket can be omitted (code J) if panel space is tight.
Because flow is published as curves and not as a single rating, send us your required flow and working pressure 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 G-series flow as curves rather than a single rated figure, so no single flow number is quoted here. Send us your required flow and working pressure and we will confirm the sizing from the datasheet before you order.
It decodes the fitted options: C1 is the external round gauge with MPa scale, T is the NPT thread (PT is the standard, with G and NPT as order options), and K means a reverse/check valve is fitted. The 300 size carries the 3/8 in port, and the differential-pressure drain and 40 um element are the defaults for this configuration.
