The AirTAC GFR300C10C2 AirTAC Filter Regulator PT3/8, psi 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 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 GFR300C10C2 is a size-300 filter regulator that removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration has a PT3/8 port, the standard 40 um filter element, a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the bowl is high enough, and an external round gauge reading in psi so operators can set and monitor pressure directly. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and a mounting bracket is included for panel or wall fixing.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with a choice of ports, PT, G or NPT threads, manual, automatic or differential-pressure drains, a 5 um (code W) element in place of the standard 40 um, square embedded or external round gauges in MPa, psi or bar scales, and a low-pressure type. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures for your application before ordering.

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.

Installed ahead of a CNC machine's pneumatic circuit, the GFR300C10C2 strips water and swarf-laden particulate from the shop-air line and holds a steady regulated pressure for clamps, tool-changers and air-powered actuators, with the psi gauge letting setters verify setpoint at a glance.
On a carton-sealing or wrapping line, this filter regulator feeds the sealing cylinders and gripper actuators from a shared header, keeping condensate and pipe-scale out of the valves while the regulator holds the pressure the machine builder specified.
Mounted at the manifold serving conveyor diverters, stops and pushers, the unit cleans the plant air supply and regulates it to the pressure the divert cylinders need, with the differential-pressure drain handling accumulated moisture without daily manual blowdown.
Choose the size and port step against the air demand of the circuit: this unit is size 300 with a PT3/8 port, and larger sizes carry larger ports and more flow. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. The drain here is differential-pressure, which discharges condensate on pressure differential with no operator attention; automatic and manual drains are alternative order codes. The filter grade is the standard 40 um; a 5 um element is available as code W if finer filtration is needed. The gauge on this model is the external round type reading in psi; embedded square gauges and MPa or bar scales are other options. The thread is PT as standard, with G (BSPP) and NPT available to order, and a mounting bracket is included.
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 characteristic curves rather than a single rated figure, so we do not quote a rated flow, Cv or l/min number. Tell us your line pressure, downstream pressure and air demand, and we will confirm the sizing against the datasheet curves on request before you order.
The GFR300C10C2 has the differential-pressure drain as standard: condensate collected in the bowl is discharged automatically whenever the pressure differential across the bowl is sufficient, so there is no daily manual draining. If your application needs a fully automatic float drain or a manual drain instead, those are available as different order codes in the same GFR300 size.
