The AirTAC GFR30010AF1WT AirTAC Filter Regulator NPT3/8 5 um 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 GFR30010AF1WT is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This configuration has a 3/8 in NPT port, a 5 um filtration element, an automatic drain that expels collected condensate without manual attention, and a built-in square pressure gauge reading in MPa. The standard regulator covers 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the polycarbonate bowl suits ambient temperatures of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 in, and options include manual or differential-pressure drains, a 40 um standard element, external round gauges with MPa, psi or bar scales, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rating, so ask us to confirm sizing figures from the datasheet 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.

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.

Filter and regulate the air feeding solenoid valves on an automated assembly line, keeping contaminants out of valve spools and holding a stable setpoint to the actuators.
Supply sorting and stopper cylinders on a packaging conveyor with filtered, regulated air so diverters stroke consistently through a full shift without manual drain checks.
Feed power clamps and swing cylinders on a CNC fixture circuit, where 5 um filtration protects seals and steady regulated pressure keeps clamping force repeatable.
Size the GFR300 to your line: the 300 frame with a 3/8 in NPT port sits mid-range in the 200/300/400/600 series, and the right frame depends on the flow your application needs - we can confirm curve data from the datasheet before you order. This unit pairs a 5 um element (the 40 um standard is available as an alternative) with an automatic drain, a good match where the unit is mounted out of easy reach. The square gauge reads in MPa; round external gauges with psi or bar scales are orderable. Threads come as PT standard with G (BSPP) and NPT as order options, and a mounting bracket is included.
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 GFR300 as curves rather than a single rated figure, so we do not quote a number here. Ask us and we will confirm the flow curve and check your sizing against the datasheet before you order.
The W code fits a 5 um element instead of the 40 um standard, giving finer particulate removal for downstream valves and cylinders. The A code adds an automatic drain, so condensate is expelled without manual attention - useful where the unit sits in a crowded panel or above shoulder height.
