The AirTAC GFR30010NWT AirTAC Filter Regulator 3/8 in NPT 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 AirTAC GFR30010NWT is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 300-size unit has 3/8 in NPT ports, a 5 um filter element (code W) instead of the 40 um standard, and a differential-pressure drain, the standard drain arrangement for this range. No pressure gauge is fitted (code N) and the regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi). Maximum inlet pressure is 1.0 MPa (145 psi), the operating temperature range is -5 to 70 C (non-freezing), and the 300-size bowl is polycarbonate (PC). A mounting bracket is included.
This is a genuine AirTAC part. The GFR range spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, and gauge options. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details for your application.

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.

| 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. |

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.

Filtering and regulating the air feeding tool-clamp and actuation circuits on a CNC machining centre, where the 5 um element helps protect directional valves from particulate and condensed water.
Setting a stable supply pressure for carton-forming and sealing cylinders on a packaging line, with the differential-pressure drain handling condensate without a manual drain routine.
A point-of-use filter regulator at an assembly-station air drop, trimming working pressure for air tools and small actuators on the line.
Choose the size and port to match your flow requirement: this unit is size 300 with 3/8 in NPT ports (thread code T; PT is the standard thread and G/NPT are order options). Filtration here is the 5 um element (code W) - select 5 um where downstream valves, cylinders or instruments need finer air than the 40 um standard. The drain is the differential-pressure type; automatic (A) and manual (M) variants exist if you prefer. A gauge is not fitted on this code (N); gauge variants with MPa, psi or bar scales are available in the GFR300 range. A mounting bracket is included.
Flow for the GFR series is published as curves, not a single rated figure - send us your flow and pressure requirement 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 flow for the GFR series 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 against the datasheet on request.
No. The N in GFR30010NWT means no gauge is fitted. Gauge variants of the GFR300 are available with MPa, psi or bar scales - ask us if you need one.
