The AirTAC GFR300C10ALF2T AirTAC Filter Regulator 3/8 in NPT 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 See datasheet 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 GFR300C10ALF2T is a filter regulator: water-and-particulate filtration and pressure regulation built into one body, so a single panel position does both jobs. This unit is the size 300 model with a 3/8 in NPT port, an automatic drain that discharges collected condensate from the polycarbonate bowl without operator attention, and the standard 40 um filter element. It carries the low-pressure regulator type - the catalogue does not publish an exact adjustment range for this version, and we confirm it on request. An embedded square gauge graduated in psi is fitted, a mounting bracket is included, and the unit is rated for a maximum inlet pressure of 1.0 MPa (145 psi) over -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options across the range include manual or differential-pressure drains, a finer 5 um element (code W), gauge scales in MPa, psi or bar, and G (BSPP) or NPT threads ordered in place of the PT standard. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm sizing and any datasheet figure against your application 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.

Filtered, regulated air to the gripper and cylinder circuit of a pick-and-place robot cell on an electronics assembly line, where the automatic drain keeps condensate out of the bowl without a manual bleed routine.
Air preparation for the clamp and flap-fold cylinders on a carton sealing machine at the end of a packaging line, with the psi-scale square gauge giving operators a local pressure readout at the machine.
Regulated supply to the clamping cylinders of a CNC machining fixture, with the 40 um element taking water and particulate out of the mill air before it reaches the fixture valves.
Choose the size by port and flow: sizes 200, 300, 400 and 600 step up through 1/8 to 1 in ports, and the right step depends on the flow your line needs - we can check the published flow curves against your demand. Drain type is a real choice on this family: the differential-pressure default, automatic (as fitted here), or manual. Filter grade is 40 um standard or 5 um with code W where finer filtration is needed. Gauges are embedded square as standard with an optional external round gauge, in MPa, psi or bar scales, and threads can be ordered in PT (the standard), G (BSPP) or NPT. This unit already carries the low-pressure regulator type, an automatic drain, a square psi gauge and a 3/8 in NPT port. Because flow is published as curves and not a single rating, 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 GFR series as curves rather than a single rated number, so we do not quote a rated flow, Cv or SCFM figure for this unit. Tell us the flow demand of your line and we will confirm the sizing against the datasheet curves on request before you order.
GFR is the filter-regulator family, 300 is the size, 10 is the 3/8 in port, A is the automatic drain, L is the low-pressure regulator type, F2 is the embedded square gauge with a psi scale, and T is the NPT thread. The 40 um element fitted is the standard grade; the finer 5 um element is ordered with code W.
