The AirTAC GFR30010AC1T AirTAC Filter Regulator NPT 3/8 in 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 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 GFR30010AC1T is a 300-size filter regulator that removes water and particulate from compressed air and sets downstream pressure in one compact body. This configuration has 3/8 in NPT ports, an automatic drain that ejects collected condensate without manual attention, standard 40 um filtration, a standard regulator with a 0.15-0.9 MPa (20-130 psi) adjustment range, and a round pressure gauge with an MPa scale. A mounting bracket is included and the polycarbonate bowl is rated for the full 1.0 MPa (145 psi) maximum inlet pressure, with an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR filter-regulator line is available in sizes 200, 300, 400 and 600 with a choice of ports, thread types (PT standard, G and NPT as options), drain types, 40 um or 5 um filtration, gauge styles and scales, and a reverse/check valve option. Flow is published as curves rather than a single rating, so we 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.

Point-of-use conditioning for the tool-clamp and pallet-changer circuits on a CNC machining centre: the 40 um element strips water and swarf-laden debris before the regulator sets a steady pressure to the clamping valves, and the automatic drain keeps the bowl clear on unattended shifts.
Feeding the pop-up diverters and stop-gate cylinders on a packaging conveyor: the regulator holds a consistent setting so divert strokes stay repeatable, while the automatic drain handles condensate along a line where nobody opens a bowl between changeovers.
Conditioning the supply to quarter-turn pneumatic valve actuators on a process skid: the 40 um grade protects the actuator's control accessories from particulate, the round MPa gauge gives operators a local pressure readout, and the NPT 3/8 in ports suit typical actuator supply tubing.
Start with the port step: the 300 size with 3/8 in NPT ports sits mid-range in the GFR line, so step up to 400 or 600 if your line demands more air, or down to 200 for compact circuits. Choose the drain to match access: this automatic-drain version suits installations that are not checked daily, while manual and differential-pressure drains are also available. Filtration is 40 um as standard here; specify the W variant for 5 um where finer protection is needed. The round MPa gauge is fitted; square gauges and psi or bar scales can be ordered instead, and PT, G or NPT threads are selected at order time. 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 the GFR300 series as curves, not as a single rated figure, so we do not quote a number here. Tell us your operating pressure and air demand and we will confirm the datasheet flow curve and sizing for your application on request.
The A in the code specifies an automatic drain, which ejects collected condensate from the bowl without manual intervention - the right choice for installations that are not checked daily. Manual and differential-pressure drain versions of the same GFR300 filter regulator are also available if you prefer scheduled draining.
