The AirTAC GFR30010JF3T AirTAC Filter Regulator 3/8 in NPT is a genuine G-series filter regulator: water separation, 40 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 GFR30010JF3T is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate down to 40 um and regulates downstream pressure across 0.15-0.9 MPa (20-130 psi). This configuration has a 3/8 in NPT port, the differential-pressure drain (default), a fitted embedded square gauge with bar scale, and no mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl suits transparent level checking at this size.
This is a genuine AirTAC part. The GFR300 series is one of four sizes (200/300/400/600) with port options from 1/8 to 1 in, thread choices of PT (standard), G or NPT, drain types (differential-pressure, automatic or manual), a 5 um filter grade option, gauge scale options and optional brackets. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application 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.

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.

Conditions and regulates the air feeding a machining centre's tool-change cylinders and clamping circuits, holding a steady set pressure from a shop-air main.
Filters the supply to pneumatic clamping fixtures on a production fixture line and regulates the clamp pressure the operator sets on the bar gauge.
Prepares air for the stopper and pusher cylinders along a packaging conveyor, keeping water and particulate out of the directional valves downstream.
Size and port step up with required flow: the GFR300 with its 3/8 in NPT port sits mid-range in the 200/300/400/600 ladder, so step to 400 or 600 for larger air demand and down to 200 for compact lines. Choose the drain to match duty: this unit carries the differential-pressure drain (default); automatic drain (code A) suits unattended installations and manual drain (code M) suits supervised points. The 40 um grade fitted here is the standard element; specify code W for the 5 um grade where finer particulate removal is needed. The square gauge with bar scale is fitted; MPa or psi scales and an external round gauge are alternatives. Thread is NPT here; PT is the standard thread and G is also an order option. A bracket can be added if this no-bracket code does not suit your mounting. Flow 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 publishes flow for this series as curves rather than a single rated figure, so no rated flow number is stated here. Tell us your application and line pressure and we will confirm the flow and datasheet figures for the GFR300 at 3/8 in on request before you order.
This configuration carries the differential-pressure drain, the default for the GFR series, which discharges collected condensate automatically as the pressure differential across the element changes. If the unit will run unattended or at low duty, the automatic drain (code A) is available; for supervised installation points, the manual drain (code M) is an option.
