The AirTAC GFR300C10C2T AirTAC Filter Regulator NPT3/8 40 um 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 AirTAC GFR300C10C2T is a filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single body. This size 300 unit has a 3/8 in NPT port, 40 um standard filtration, a differential-pressure drain that bleeds collected condensate whenever the pressure drop across the element rises, and a standard regulator adjustable from 0.15 to 0.9 MPa (20-130 psi). An external round gauge with a psi scale is fitted so the set pressure is readable at the unit, and a mounting bracket is included for panel or wall fixing. The bowl on this size is polycarbonate.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600, with port options from 1/8 to 1 in, G (BSPP) or NPT threads as order options alongside the PT standard, automatic or manual drain variants, a 5 um (code W) filter grade, square or round gauges with MPa, psi or bar scales, and a low-pressure regulator type. Published flow data is given as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

Feeds filtered, pressure-set air to the clamps and tool-change actuators on a CNC machining centre, with the psi gauge letting the setter read the clamp circuit setting directly at the unit.
Conditions the air supply to the stopper and pusher cylinders along a packaging conveyor, keeping water and debris out of the valves while holding a stable setting for consistent stroke timing.
Serves as the single filter-regulator point for the gripper and capping heads on a bottling line, with the differential-pressure drain clearing condensate between production runs without operator attention.
Size the unit by the port step and the flow your line needs: this size 300 unit carries a 3/8 in NPT port, one step up from 1/4 in, and the GFR range runs from 1/8 in (size 200) to 1 in (size 600). Choose the drain to match maintenance access: differential-pressure (this unit, no operator action), automatic (self-draining), or manual (drained by hand). Choose the 40 um standard element for general air prep or the 5 um W-code element where finer filtration is wanted. Gauge scale (psi on this unit; MPa or bar also available) and thread (PT standard, G or NPT to order) are decodable choices, and a bracket can be included or omitted.
Flow for this family is published as curves, not a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the sizing and datasheet figures 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 series as curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and datasheet figures for this 3/8 in NPT unit on request before you order.
The 40 um element (fitted on this unit) is the standard grade for general air preparation ahead of valves and cylinders. The 5 um grade, ordered with the W code, suits applications that need finer particulate removal. Both grades are available across the GFR range, and the drain and gauge options stay the same either way.
