The AirTAC GFR30010C1TK AirTAC Filter Regulator NPT3/8 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 GFR30010C1TK is a 300-size filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 3/8 in NPT port, the standard 40 um filter element, a differential-pressure drain that bleeds condensate automatically as flow passes through, and a round pressure gauge with an MPa scale. A reverse (check) valve is fitted, the regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the polycarbonate bowl is rated for a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of port sizes, PT, G or NPT threads, differential-pressure, automatic or manual drains, a 5 um (code W) filter element where finer filtration is needed, gauge scale options, and a reverse-valve variant. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the datasheet figures 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.

On a CNC machining cell, this unit feeds the fixture-clamping circuit: the 40 um element keeps chips-laden condensate out of the clamp cylinders, the regulator holds a steady clamping pressure, and the check valve holds the downstream circuit if supply pressure dips.
On a carton packaging line, the GFR30010C1TK conditions the air feeding conveyor stoppers, pushers and diverters, with the differential-pressure drain shedding accumulated water during continuous running and the MPa gauge letting operators verify set pressure at a glance.
At a bench-mounted assembly station with air tools and small actuators, this filter regulator cleans and regulates the drop from the main header, and the included bracket lets it be panel-mounted right at the point of use.
Size and port step up together: 200, 300, 400 and 600 cover progressively larger ports and higher flow, so pick the smallest size whose published flow curve covers your demand with margin - we can check the curve against your application before you order. This unit's other choices are all decodable from the code: drain type (differential-pressure as here, automatic, or manual - note the manual-drain variant widens the regulation range down to 0.05 MPa), filter grade (40 um standard, 5 um with code W), gauge type and scale (embedded square or external round; MPa, psi or bar), thread (PT is the standard; G and NPT are order options), and whether a reverse/check valve is fitted. A mounting bracket is included.
One honest note on sizing: AirTAC publishes flow as curves, not a single rated figure, so we do not quote a flow number here. Tell us your line pressure, set pressure and air demand and we will confirm the correct size from the datasheet on request.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so we do not quote a flow number here. Send us your inlet pressure, set pressure and air demand and we will confirm the sizing from the datasheet on request.
K means a reverse (check) valve is fitted, holding downstream pressure if the supply drops. The drain position is blank in this code, which is the differential-pressure drain: condensate is discharged automatically as air flows through, with no manual draining needed. Automatic (A) and manual (M) drains are available as order options.
