The AirTAC GFR300C10ANWT AirTAC Filter Regulator 3/8 in 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 GFR300C10ANWT is a 300-size filter regulator that removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration carries a 3/8 in NPT port, a 5 um filter element (code W), an automatic drain that ejects collected condensate without manual attention, and a standard regulator adjustable from 0.15 to 0.9 MPa (20-130 psi). Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). No pressure gauge is fitted (code N) and no reverse/check valve is included; a mounting bracket is supplied. At size 300 the bowl is polycarbonate.
This is a genuine AirTAC part. The GFR family is published in 200, 300, 400 and 600 sizes with port options from 1/8 in to 1 in, PT as the standard thread and G (BSPP) or NPT as order options, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um filtration, gauge variants and scale choices, and low-pressure or standard regulator types. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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.

Clean, regulated air feeding the tool-change clamps and pneumatic actuators on a machining centre, with the 5 um element protecting directional valves from particulate and the automatic drain handling condensate between shifts.
Pressure regulation for the cylinders and grippers on a carton-forming and sealing conveyor, where the automatic drain keeps water out of the circuit without a technician stopping the line to bleed the bowl.
A filtered, regulated drop at a bench or fixture on an assembly line, giving each operator a stable set pressure for air tools and clamping fixtures while the 5 um element guards the downstream fittings.
Size up by port and flow demand: the 300 size with its 3/8 in NPT port suits lines above the 1/4 in class; step to 400 or 600 for larger air demand and to 200 for smaller points of use. Choose the drain to match attendance: automatic (this unit) for unattended duty, manual where an operator drains routinely, or the differential-pressure default. Choose the 5 um element (this unit) where downstream valves and actuators need finer particulate control, or the 40 um standard element for general pre-filtration. Gauge variants (embedded square or external round, with MPa, psi or bar scales) and a reverse/check valve are available on other codes; this code has none. Thread is NPT here, with PT as the catalogue standard and G (BSPP) as an alternative order option; a no-bracket (J) variant exists if you do not want the supplied bracket.
Because AirTAC publishes flow as curves rather than a single rated number, ask us to confirm the flow curve and datasheet figures for this exact code 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 series as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow curve and datasheet figures for this exact code on request before you order.
No. The N in the code means no gauge is fitted. Gauge options exist across the GFR range - an embedded square gauge or an external round gauge, with MPa, psi or bar scales - so if you need a gauge on the regulator, ask us for the corresponding GFR300 code.
