The AirTAC GFR30010JF2WTK AirTAC Filter Regulator NPT3/8 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 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 GFR30010JF2WTK 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 threaded 3/8 in NPT, carries the fine 5 um filter element (code W), drains condensate by differential pressure, and has an embedded square gauge reading in psi. A reverse/check valve is fitted to hold downstream pressure, and no mounting bracket is included.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch and options including automatic or manual drains, 40 um or 5 um filtration, gauge scale in MPa, psi or bar, and G, NPT or PT threads. Flow is published as curves rather than a single rating, so we confirm the datasheet and sizing figures on request.

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.

| 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.

Feeding filtered, regulated air to a bench pneumatic press or clamping fixture, where the 5 um element protects precision cylinders and the check valve holds set pressure if the main supply dips.
Conditioning the air supply to conveyor diverters, carton sealers and bagging heads, where the square psi gauge lets operators verify set pressure at a glance and the differential-pressure drain keeps condensate off the valves.
Supplying clean, regulated air to laboratory apparatus, test benches and pilot panels, where the 5 um grade and a stable, gauge-monitored setting protect sensitive instrumentation downstream.
Choose the size and port step against the air your application actually consumes: this unit is the 300 size with a 3/8 in NPT port, and larger sizes carry larger ports and more flow. The 5 um element (code W) suits downstream equipment that needs finer filtration than the 40 um standard; the differential-pressure drain bleeds condensate automatically as flow passes through, with no manual draining routine. The square gauge here reads psi; MPa and bar scales are also available, and an external round gauge is optional. The fitted check valve holds downstream pressure if the upstream supply drops. Thread is NPT on this unit; G (BSPP) and PT are catalogue alternatives. Bracket: not included on this code. Because flow is published as curves rather than a single rating, 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this series as curves, not as a single rated figure, so we do not quote a number. Tell us your application and required flow, and we will confirm the sizing against the datasheet curves on request before you order.
The W in the code GFR30010JF2WTK specifies the optional 5 um filter element instead of the 40 um standard, and the K specifies a fitted reverse/check valve that holds downstream pressure if the upstream supply is lost. Both are catalogue options you can order with or without on other GFR300 codes.
