The AirTAC GFR300C08JF1TK AirTAC Filter Regulator NPT1/4 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 GFR300C08JF1TK 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 1/4 in NPT port, a 40 um standard filter element, a metal bowl with differential-pressure drain, an embedded square gauge scaled in MPa, and a reverse (check) valve fitted; no mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), the regulation range is 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part in the 300 size of the G-series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in and PT, G or NPT thread options. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures for your application on request.

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 filter regulator at a 1/4 in drop feeding clean, regulated air to solenoid valves and pneumatic clamps on a CNC machining cell, with the check valve holding downstream pressure if the main supply drops.
Filtering and regulating supply air to carton-sealing cylinders and small actuators along a packaging conveyor, where the 40 um element protects downstream valves from water and debris.
Filter regulator ahead of air tools and pneumatic press fittings at a factory assembly bench, giving operators a locally adjusted, moisture-reduced supply at the 1/4 in take-off.
The real, decodable choices within the GFR300 are the port and thread (this unit is NPT1/4; PT is the standard thread and G or NPT are catalogue options to order), the filter grade (40 um standard here, 5 um with code W), the drain type (differential-pressure here, with automatic and manual available), the gauge (square MPa scale fitted here, with psi or bar scales and an external round gauge as options), and whether a reverse/check valve or mounting bracket is required. Regulation range for this configuration is 0.15-0.9 MPa (20-130 psi).
Because AirTAC publishes flow as curves rather than a single rated figure, we do not quote a flow number here. Send us your application details 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 flow for the GFR300 as curves, not as a single rated figure, so we do not quote a flow number on this page. Send us your application flow and pressure requirements and we will confirm sizing from the datasheet on request.
K means a reverse (check) valve is fitted, which helps hold downstream pressure if the upstream supply is interrupted. Other decodable choices on this unit are the NPT1/4 thread (PT is the standard, with G and NPT as order options), the 40 um filter element (5 um with code W), the differential-pressure drain (automatic or manual available) and the square gauge scaled in MPa (psi or bar scales available).
