The AirTAC GFR30010C2TK AirTAC Filter Regulator NPT3/8 with Gauge 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 GFR30010C2TK is a size 300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration has a 3/8 in NPT port, a 40 um standard filtration element, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and a polycarbonate bowl. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, a round external gauge reading in psi is fitted, and a reverse/check valve (code K) holds downstream pressure when the upstream supply is lost. A mounting bracket is included.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, manual or automatic drain options, a 5 um (code W) element option, gauge scale choices and G/NPT thread variants. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing 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.

Cleaned and pressure-set air for a plant-air drop feeding air tools, clamps and small cylinders, with the check valve holding the circuit if the main supply dips.
Filtered, regulated air for conveyor stopper cylinders and diverters on a packaging or bottling line, with the psi gauge letting operators set and verify line pressure at a glance.
Point-of-use air prep at a maintenance bench or spray station, where the 40 um element keeps water and grit out of guns and nozzles and the regulator holds a steady working pressure.
Size 300 with a 3/8 in port sits in the middle of the GFR range; step up to 400/600 or down to 200 depending on the flow your line needs - ask us to check the published flow curves against your demand before ordering. Drain choice is differential-pressure here (standard), with automatic (A) and manual (M) variants available in the series. The 40 um element suits general pneumatic supply; specify the W code for a 5 um grade where finer pre-filtration is needed. This unit is ordered with NPT thread; G (BSPP) and PT are the other catalogue options. If you prefer an embedded square gauge or a different scale (MPa/psi/bar), those are decodable choices on adjacent codes.
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, not as a single rated number, so there is no one figure we can quote. Tell us your working pressure and air demand and we will confirm the sizing against the datasheet curves on request before you order.
K means a reverse/check valve is fitted: it holds downstream pressure if the upstream supply is interrupted. This unit's drain is the differential-pressure type (no A or M in the code), which bleeds collected condensate automatically as air flows through; automatic (A) and manual (M) drain versions are available in the same series.
