The AirTAC GFR30008JC1T AirTAC Filter Regulator, NPT1/4, Round Gauge 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 PT1/4" 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 GFR30008JC1T is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in a single body, sized for a 1/4 in (NPT) port. This configuration carries the standard 40 um filter element for water and particulate removal, a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough, and a standard regulator with a setting range of 0.15-0.9 MPa (20-130 psi). A round external gauge on an MPa scale is fitted so the downstream setting can be read at a glance, and the unit is supplied without a mounting bracket. The polycarbonate bowl suits the -5 to 70 C (non-freezing) operating range, and maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part from the GFR family, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in and filter grades of 40 um standard or 5 um (code W). Drain, gauge and thread options can be selected at order time. Because AirTAC publishes flow only as curves rather than a single rated figure, we confirm the datasheet and flow data 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.

Feeds filtered, regulated air to the tool-change clamps and pneumatic actuators on a CNC machining centre, protecting the valves from water and chips carried in the shop air line.
Conditions the air feeding the pusher and clamp cylinders on a carton packaging line, holding a steady downstream pressure so sealing and eject strokes stay repeatable through the shift.
Sits upstream of the solenoid valve manifold on a small assembly cell, removing condensate and particles before the valves while the fitted MPa gauge lets technicians verify the set pressure.
Start with the port and size step: this unit is a GFR300 with a 1/4 in NPT port, one step up from the GFR200 1/8 in size and below the GFR400 1/2 in size, so match the size to the air consumption of the circuit it feeds. Choose the drain type: this unit has the differential-pressure drain (default); an automatic drain (code A) or manual drain (code M) are available, and note the regulation range differs by drain type. Choose the filter grade: 40 um standard here, 5 um (code W) where finer filtration is needed. Gauge, scale (MPa/psi/bar), thread (PT standard, G and NPT to order) and bracket options complete the selection. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your application and we will confirm the flow data from the datasheet on request before you order.
This unit has the differential-pressure drain (the default): it discharges collected condensate automatically when the pressure differential across the filter element is high enough. If you prefer, the GFR300 is also available with an automatic drain (code A) or a manual drain (code M); note that the regulator setting range differs by drain type.
