The AirTAC GFR30010C2WG AirTAC Filter Regulator G3/8, 5 um is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/8" 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 GFR30010C2WG is an AirTAC GFR-series filter regulator: filtration and pressure regulation combined in one body. This 300-size unit has a G3/8 (BSPP) port, a 5 um filter element for finer water and particulate removal than the standard 40 um grade, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element rises. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), and this configuration is fitted with a round gauge reading in psi. Maximum inlet pressure is 1.0 MPa (145 psi), operating temperature is -5 to 70 C (non-freezing), and the polycarbonate bowl suits general plant air.
This is a genuine AirTAC part. The GFR family is published in 200, 300, 400 and 600 sizes with port options from 1/8 to 1 inch, 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, and PT, G or NPT threads. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details 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.

Feeding press cylinders and clamping fixtures on a fabrication cell: the 5 um element keeps wear particles and water out of the valve stack while the regulator holds a steady clamping pressure, and the psi round gauge gives the operator a direct set-point readout.
Supplying diverters, pushers and sealing jaws on a packaging conveyor: the differential-pressure drain clears condensate as the element loads, so the line keeps running between maintenance rounds, and the regulator holds consistent actuator speed and sealing force.
Conditioning shop air for a lab test rig or instrument bench: the 5 um grade protects sensitive pneumatic instruments from fine particulate, the regulator sets a stable test pressure, and the round psi gauge allows precise verification of the set point.
Size the unit by the flow your line needs at the outlet pressure you run: the 300 size with its 3/8 in port is the middle step of the range, and moving up to 400 or 600 buys more flow capacity at a larger port. This unit already carries the 5 um element (code W); the standard grade is 40 um, so choose 5 um where downstream valves, cylinders or instruments need finer protection. Drain type matters: the differential-pressure drain fitted here needs no daily attention, while an automatic drain (code A) drains continuously and a manual drain (code M) is emptied by hand. The round psi gauge fitted here can be swapped for a square gauge or an MPa or bar scale, and the thread is G (BSPP) - PT is the standard offering, with G and NPT as order options. A mounting bracket is included. Because flow is published as curves rather than a single rated figure, send us your flow and pressure requirements and we will confirm the right size against 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 rather than a single rated figure, so we do not quote one number here. Tell us your inlet pressure, set pressure and required flow, and we will confirm against the datasheet whether the 300 size at 3/8 in suits your application before you order.
The differential-pressure drain fitted to this unit releases collected condensate automatically whenever the pressure drop across the 5 um element rises, so it needs no daily manual draining. If you want continuous draining regardless of differential, order the automatic-drain version (code A); if you prefer to drain by hand on a fixed schedule, the manual-drain version (code M) is available in the same size.
