The AirTAC Airtac GFR Filter Regulators GFR30010AF1T 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 GFR30010AF1T is a 300-size filter regulator that removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration is fitted with a 3/8 in NPT port, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, and an embedded square gauge scaled in MPa so the set pressure is always visible at the unit. The regulator adjustment range is 0.15-0.9 MPa (20-130 psi), with a maximum working (inlet) pressure of 1.0 MPa (145 psi), and the unit operates from -5 to 70 C in non-freezing conditions. The polycarbonate bowl suits indoor, guarded installations.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of ports, PT/G/NPT threads, manual, automatic or differential-pressure drains, a 5 um (W) element option, gauge scale options, and a low-pressure type on request. Flow is published as curves rather than a single rating, so we confirm the datasheet and sizing figures on request before you order.

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 filtered, regulated air to a bench-mounted pneumatic press or clamping fixture, where the automatic drain keeps condensate out of the valve stack and the MPa gauge lets the setter verify set pressure at a glance.
Conditioning the air supply to conveyor diverters, case sealers and carton-forming cylinders on a packaging line, with the 40 um element protecting directional valves and the regulator holding consistent cylinder speed.
Installed at the air drop entering a machine control panel or manifold assembly, combining water and particulate removal with a stable regulated supply for pilot valves, air logic and panel-mounted actuators.
Start with the port step: this unit is 3/8 in NPT, so match it to the line size and the flow your circuit needs - larger sizes (400, 600) carry more flow at the same pressure drop. Choose the drain to match access: automatic (this unit) suits enclosed or hard-to-reach panels, manual suits attended stations, and differential-pressure drain is the catalogue default. The 40 um element is standard; order the 5 um (W) grade where finer particulate protection is required. The embedded square gauge is MPa-scaled; psi and bar scales and an external round gauge are options. PT is the standard thread and G/NPT are order options; a mounting bracket is included. Flow is published as curves, not a single rated figure, 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 rather than a single rated figure, so we do not quote a flow number. Tell us your line pressure, set pressure and expected air demand, and we will confirm the sizing against the datasheet curves on request before you order.
The A in the code sets an automatic drain, which expels collected condensate from the bowl without anyone opening it - useful for enclosed panels or infrequently visited installations. Manual drain (code M) suits attended stations where an operator drains the bowl, and differential-pressure drain is the catalogue default; all three are orderable on this series.
