The AirTAC AirTAC GFR300-10 Filter Regulator (GFR30010ANW) 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 automatic 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 GFR30010ANW is a filter regulator: filtration and pressure regulation combined in one body. This 300-size unit is built around a 3/8 in PT port. The W suffix selects the finer 5 um filter element instead of the standard 40 um, and the A suffix specifies an automatic drain, so collected condensate is expelled without manual attention. The N suffix means no gauge is fitted. Regulation range with automatic drain is 0.15-0.9 MPa (20-130 psi), max working pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl suits the 300 size.
This is a genuine AirTAC part from the G series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in and PT, G (BSPP) or NPT thread options. AirTAC publishes flow performance as curves rather than a single rated figure, so we confirm the datasheet and sizing numbers on request 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.
| GFR300 | G-series filter regulator, 300 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT 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.

Feeds filtered, regulated air to a machining centre's tool-clamp and chip-clearing cylinders, with the 5 um element protecting precision valves from fine particulate and the auto drain handling condensate.
Prepares clean, regulated compressed air for lab automation and analytical-instrument actuation, where the 5 um grade and unattended automatic drain keep the point-of-use supply stable.
Serves as the air-preparation stage on a pneumatic control panel, delivering regulated air to positioners and pilot valves without a gauge when the panel carries its own instrumentation.
Choose size 300 with the 3/8 in port when your line flow sits above what a 200-size 1/4 in unit can pass; step up to 400 or 600 for larger demand, or down for compact circuits. The 5 um element here suits air feeding sensitive valves and instruments; pick the standard 40 um grade for general shop-air protection. Automatic drain suits unattended or hard-to-reach installations; manual and differential-pressure drains are also available in the family. This version has no gauge (order a gauge variant if you want visual setting), uses standard PT thread, and can be ordered without a bracket (J suffix) if panel or manifold mounting is preferred.
Flow for this family is published as curves, not a single rating, so 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 does not publish a single rated-flow figure for this unit; flow performance is given as curves in the datasheet. Contact us with your application demand and we will confirm the sizing from the datasheet on request.
The W suffix upgrades filtration from the standard 40 um to 5 um for finer protection of downstream valves and instruments, while the A suffix gives an automatic drain that expels condensate on its own - useful where bowls are not checked daily. A manual or differential-pressure drain version is available if you prefer.
