The AirTAC GFR300C10C2W AirTAC Filter Regulator 3/8 in PT 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 GFR300C10C2W is a 300-size filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is fitted with a 3/8 in PT port, a 5 um filter element (the finer of the two available grades), a differential-pressure drain that bleeds condensate automatically as flow passes through, a round pressure gauge reading in psi, and a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi). Operating temperature is -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 port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, square or round gauges with MPa, psi or bar scales, PT, G or NPT threads, and low-pressure or standard regulator types. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Filtered, regulated air at a set pressure feeds the tool-changer and clamping circuits on a machining centre, with the 5 um element protecting tight-tolerance pneumatic components from water and swarf carried in the shop air line.
On a carton-forming and sealing line, the filter regulator conditions the supply to the pick-and-place and sealing cylinders, holding a stable set pressure so jaw force and transfer timing stay consistent through the shift.
At the point of use in a spray booth, the unit strips water and fine particulate before the regulator sets the atomising pressure at the gun, helping deliver a clean, repeatable finish.
Choose the size and port step against the air consumption of the circuit served - larger sizes carry larger ports and more flow capacity - and confirm the match against the published flow curves before ordering. This unit already carries the finer 5 um element (W code); the standard grade is 40 um if your application does not need the finer filtration. The differential-pressure drain on this model needs no operator attention; automatic and manual drains are available elsewhere in the range if your duty cycle suits them better.
The round gauge fitted here reads in psi; square embedded gauges and MPa or bar scales are the other catalogue options. Thread is PT as standard, with G (BSPP) and NPT available as order options, and a mounting bracket is included. Because flow is published as curves rather than a single rating, send us your application details and we will confirm sizing from the datasheet before you order.
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, not as a single rated number, so we do not quote a l/min or SCFM figure. Send us your application details and we will confirm the flow data from the datasheet and check the sizing against your air consumption before you order.
The W code in GFR300C10C2W selects the optional 5 um filtration element; the standard grade for the GFR series is 40 um. The 5 um element is the right choice where downstream valves, cylinders or process equipment need finer protection from particulate and water carry-over. Both grades are available across the GFR range, so you can match the element to each point of use.
