The AirTAC GFR30010JF1WT AirTAC Filter Regulator NPT 3/8 in 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 GFR30010JF1WT is a 300-size filter regulator that removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration carries a 5 um filter element (code W) for finer filtration than the standard 40 um grade, a differential-pressure drain that bleeds condensate automatically as flow passes through, an embedded square pressure gauge scaled in MPa, and NPT 3/8 in ports. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the polycarbonate bowl lets you see the condensate level at a glance. Maximum inlet pressure is 1.0 MPa (145 psi), with an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, 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 the 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 0.15 - 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.

Feeding the pneumatic cylinders and grippers on a carton-forming and sealing line: the 5 um element protects valve spools from fine particulate, the regulator holds a stable working pressure, and the square MPa gauge gives operators a clear setpoint reference.
Supplying the air cylinders that divert, stop and index product on a bottling or food conveyor line, where the differential-pressure drain keeps condensate down during continuous shifts and the regulator sets the gentle pressure the stopper cylinders need.
Conditioning shop air for a test rig or lab bench with pneumatic actuators and instruments: the 5 um grade suits sensitive downstream components, the NPT 3/8 in ports match common bench plumbing, and the MPa gauge supports documented pressure settings.
Size and port set the capacity: the 300 size with 3/8 in NPT ports sits in the middle of the GFR range, a step up from 200/1/4 in units when your line draws more air, and a step below the 400 and 600 sizes for higher demand. The 5 um element (W code) suits downstream equipment that tolerates less particulate than the standard 40 um grade; the differential-pressure drain suits steady-running installations, while automatic or manual drains are the alternatives for intermittent duty or attended plants. The square gauge is scaled in MPa here, with psi and bar scales orderable, and an external round gauge is optional. NPT is the thread on this unit; PT is the catalogue standard and G (BSPP) is also available. No mounting bracket is included with this code (J code), and no reverse/check valve is fitted.
Flow for the GFR300 is published as curves, not a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the datasheet curve and sizing 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 GFR300 flow as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the datasheet curve and check the sizing against your air demand before you order.
The W code in GFR30010JF1WT selects the optional 5 um filter element instead of the standard 40 um grade, for finer particulate removal ahead of sensitive equipment. The drain is the differential-pressure type (the default): it discharges collected condensate automatically whenever the pressure differential across the filter is high enough, with no manual draining needed during flow.
