The AirTAC GFR30010C3T AirTAC Filter Regulator NPT 3/8 in 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 PT3/8" 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 GFR30010C3T is a 300-size filter regulator that removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration is threaded NPT 3/8 in, carries the standard 40 um filter element, and drains condensate by differential pressure, so the bowl bleeds itself as flow passes through. The fitted round gauge reads in bar, and the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing, and the polycarbonate bowl suits the 300 size.
This is a genuine AirTAC part. The GFR family is offered in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, an optional 5 um element (code W), square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for 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.

Clean, regulated air to a small pneumatic press or clamping cylinder on a fabrication bench, where the 40 um element keeps scale and pipe debris out of the cylinder seals while the regulator holds a steady working pressure.
Point-of-use air preparation for carton sealers and case packers, conditioning the supply to directional valves and pick-and-place cylinders so pressure stays constant as multiple stations cycle on the same header.
Filtered, regulated supply at a workstation drop for impact drivers, nut runners and air ratchets, with the differential-pressure drain and bar gauge letting operators see and hold the recommended tool pressure.
Size the GFR series by stepping port and body size against the air demand of the circuit: 200, 300, 400 and 600 cover 1/8 in up to 1 in, and this 300-size unit sits at NPT 3/8 in. Choose the drain to match maintenance access: differential-pressure (this model) drains itself in flow, automatic suits unattended installations, and manual suits intermittent duty where an operator can bleed the bowl. The standard 40 um element protects most actuators and valves; specify the 5 um W option where finer filtration is needed. Gauge style and scale (square embedded or round external; MPa, psi or bar) and thread family (PT standard, G or NPT to order) are decodable choices, and a mounting bracket is included.
Because flow is published as curves rather than a single rated figure, we do not quote a flow number here. Send us your application demand 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 GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your air demand and line conditions and we will confirm the flow and datasheet figures for this 300-size, NPT 3/8 in unit on request.
The C3 code in GFR30010C3T specifies the optional external round gauge with a bar scale; the embedded square gauge is the standard fitting. Gauges are available with MPa, psi or bar scales, so you can order the scale that matches the rest of your panel.
