The AirTAC GFR30010F2 AirTAC Filter Regulator PT3/8 Square Gauge psi 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 AirTAC GFR30010F2 is a 300-size filter regulator that cleans compressed air and holds downstream pressure in one body. It removes water and particulate down to 40 um through a differential-pressure drain bowl, then regulates outlet pressure across 0.15-0.9 MPa (20-130 psi) with the standard regulator. The embedded square gauge is fitted with a psi scale, the bowl on this 300 size is polycarbonate, and a mounting bracket is included. Porting is PT3/8 (3/8 in) with PT thread as standard.
This is a genuine AirTAC part from the GFR300 series, one of four sizes (200/300/400/600) with ports from 1/8 to 1 inch and options including 5 um filtration (code W), automatic or manual drains, alternative gauge scales, and 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.

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.

Mounted on the included bracket inside a machine's control cabinet, the GFR30010F2 cleans the plant air to 40 um and holds a steady regulated pressure to the directional valves and cylinders that run the machine's clamping and indexing sequences.
On a food or consumer-goods packaging line, this filter regulator conditions the 3/8-inch air drop feeding baggers, sealers and case packers, keeping water and debris out of the actuators while the psi gauge lets operators verify set pressure at a glance.
At the inlet of a robotic assembly cell, the unit strips condensate and 40 um particulate from the shop air and regulates it to the pressure the grippers and pick-and-place cylinders were designed for, with the differential-pressure drain handling condensate without operator attention.
Size and port set the flow capacity: this 300-size unit carries PT3/8 (3/8 in) ports, so step up to 400 or 600 if your line needs more air, or down to 200 for compact points of use. The differential-pressure drain (the default) flushes collected condensate automatically whenever the pressure differential is high enough; specify automatic (A) or manual (M) if your duty cycle calls for it. The 40 um element is the standard grade; order the W suffix for 5 um when downstream equipment needs finer protection. The fitted square gauge reads in psi; MPa and bar scales are available, and an external round gauge is optional. PT thread is standard - G (BSPP) and NPT are order options - and the included bracket simplifies panel or frame mounting.
Because flow is published as curves rather than a single rated figure, send us your application details 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 GFR300 series as curves, not as a single rated number, so we do not quote a figure here. Send us your application details and we will confirm the flow and datasheet figures for this exact PT3/8 configuration on request.
This unit's bowl uses a differential-pressure drain, which discharges collected condensate automatically when the pressure differential across the drain is high enough - no operator action needed. If your application has low or intermittent flow, or you want positive control over draining, the automatic (A) or manual (M) drain variants are available in the same size.
