The AirTAC GFR300C10AJC2WT AirTAC Filter Regulator 3/8in 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 AirTAC GFR300C10AJC2WT is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This size 300 unit is threaded 3/8 in NPT, carries a 5 um filter element, drains condensate automatically, and is fitted with a round pressure gauge reading in psi. The regulator adjusts from 0.15 to 0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and the polycarbonate bowl suits ambient temperatures of -5 to 70 C (non-freezing). No mounting bracket is fitted and no reverse/check valve is included.
This is a genuine AirTAC part from the GFR300 series. GFR filter regulators are published in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um (W) filtration, embedded square or external round gauges in 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.

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.

Filtered, regulated air to the clamping and fixture cylinders on a CNC machining cell, where a steady set pressure supports repeatable part holding.
Supply air for diverter and stopper gates on a packaging conveyor, with 5 um filtration keeping solenoid valves clean and the regulator holding gate action consistent.
Clean, regulated air to small pilot valves and actuated cylinders on a laboratory automation bench, with the automatic drain handling condensate in intermittently used lines.
Choose the size by the port and flow step: 200, 300, 400 and 600 move up through 1/8 in to 1 in ports, so pick the step that matches the air demand of your line - here 3/8 in NPT on a size 300 body. Then settle the real, decodable choices: drain type (this unit drains automatically; manual and differential-pressure versions are listed in the same series), filter grade (5 um here against the 40 um standard), gauge and scale, and thread (PT is the standard; G and NPT are order options). Brackets are optional on this family. 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 this series as curves rather than a single rated figure, so there is no one l/min or SCFM number we can quote. Tell us your application and we will confirm the flow figures from the datasheet on request.
This unit is coded A for an automatic drain, which expels collected condensate without manual attention - useful on lines that are not blown down daily. Manual and differential-pressure drain versions are listed in the same GFR series if you prefer a different arrangement.
