The AirTAC GFR30008AC2T AirTAC Filter Regulator NPT1/4, 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 PT1/4" ports, a automatic 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 GFR30008AC2T is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 300-size unit is fitted with a 1/4 in NPT port, a 40 um standard filter element, an automatic drain that ejects collected condensate without manual attention, and a round pressure gauge scaled in psi. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and the polycarbonate bowl suits operating temperatures from -5 to 70 C (non-freezing). A mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans four sizes (200, 300, 400 and 600) with port options from 1/8 to 1 in, and is configurable by drain type (differential-pressure, automatic or manual), filter grade (40 um standard or 5 um with code W), gauge style and scale, thread (PT standard, with G and NPT as order options) and bracket. Flow is published as curves rather than a single rated figure, so we confirm the exact flow and 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.

Feeding clean, regulated air to the cylinders and valves of a carton-sealing or wrapping line, with the automatic drain handling condensate between shifts without operator attention.
Conditioning the air supply to pneumatic pushers, gates and stoppers along a conveyor system, where a stable regulated pressure keeps actuator cycling consistent.
Installed at a bench or cell drop to filter line moisture and set a fixed working pressure for air tools, clamps and small pneumatic fixtures.
Start with the port step: the 300 size carries a 1/4 in port, and moving up to 400 or 600 gives larger ports and more flow capacity, while 200 steps down. Choose the drain to match maintenance access: automatic (this unit) drains condensate on its own, manual drain suits attended installations, and differential-pressure drain is the default. The 40 um element is standard; specify code W for the 5 um grade where finer particulate removal is needed. The gauge is available embedded square or external round, with MPa, psi or bar scales - this model has a round psi gauge. Thread is PT as standard, with G (BSPP) and NPT as orderable options; a bracket is included unless code J is specified.
Because AirTAC publishes flow only as curves and not as a single rated number, ask us to confirm sizing against your application's flow demand 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 GFR series as curves rather than a single rated figure, so we do not quote a rated flow number. Tell us your application's flow demand and we will confirm the sizing against the datasheet curves on request before you order.
The A in the code GFR30008AC2T specifies an automatic drain, which ejects collected condensate from the bowl without manual intervention. The alternatives are manual drain (code M) and the differential-pressure drain, which is the default when no drain code is given. The 40 um filter element is standard on this model; the 5 um grade is available with code W.
