The AirTAC GFR30010MF2WG AirTAC Filter Regulator G3/8in, 5um 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR300-10 is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single body. This unit is built on the size 300 frame with G3/8 (BSPP) ports, a 5 um filter element (the finer of the two catalogue grades), a manual drain on the polycarbonate (PC) bowl, and the standard regulator covering 0.05-0.9 MPa (7-130 psi). It is rated for compressed air at up to 1.0 MPa (145 psi) inlet and -5 to 70 C (non-freezing). An embedded square gauge with a psi scale is fitted, a mounting bracket is included, and no reverse/check valve is fitted.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, a choice of manual, automatic or differential-pressure drains, 40 um or 5 um elements, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. 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 0.05 - 0.9 MPa (7 - 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.

|---|---|
| 10 | Port size PT3/8". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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 pneumatic clamps, tool-change cylinders and chip-blow nozzles on a machining centre, with the 5 um element protecting fine-seal actuators and the psi gauge giving operators a local setpoint readout.
A point-of-use supply for carton-sealing and case-erector cylinders on a packaging line: water and scale are drained off manually at shift checks while the regulator holds a steady pressure for consistent jaw and flap actuation.
Regulated air for air screwdrivers, ratchets and riveters at a manual assembly station, where stable downstream pressure keeps fastener torque repeatable and the included bracket mounts the unit at the bench drop.
Step up or down through the GFR sizes (200/300/400/600) to match the port and flow your line needs - size 300 carries the G3/8 port here. Choose the drain to suit access: manual (this unit, which also allows the widest standard regulation range of 0.05-0.9 MPa), automatic for hands-off condensate removal, or the differential-pressure default. Pick 40 um for general protection or 5 um (code W) where finer filtration matters, and set the gauge scale to MPa, psi or bar. Thread is G (BSPP) on this unit; PT is the standard thread and NPT is an order option, and a bracket is included unless J is specified. Because flow is published as curves rather than a single rated figure, send us your flow and pressure requirements and we will confirm sizing 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 G-series flow as curves rather than a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm sizing for the GFR300-10 from the datasheet on request.
This unit uses a manual drain: condensate is released by hand, which suits points that are checked regularly. It also allows the widest standard regulation range of 0.05-0.9 MPa (7-130 psi). If you cannot guarantee regular drain checks, order the automatic (A) or differential-pressure version instead.
