The AirTAC GFR40010F2 AirTAC Filter Regulator 3/8 in PT, 40 um 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 GFR40010F2 is an AirTAC GFR-series filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate from compressed air through a 40 um element, then regulates downstream pressure over 0.15-0.9 MPa (20-130 psi). This configuration is size 400 with a 3/8 in PT port, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, an embedded square gauge reading in psi, and a mounting bracket included. The polycarbonate bowl lets you see the condensate level at a glance.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT as the standard thread and G (BSPP) or NPT as order options, a 5 um filter element (code W), automatic or manual drain alternatives, and gauge scales in MPa, psi or bar. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. 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.

Installed ahead of a pneumatic press station, this unit filters water and swarf from the shop air and holds a steady regulated pressure so the press cylinder strokes consistently from part to part.
Feeding the air cylinders that divert, stop and index product on a packaging conveyor, the 40 um element protects valve spools from particulate while the regulator keeps gate speeds repeatable.
On a laboratory automation skid running grippers and small actuator valves, the unit delivers clean, regulated air at a set pressure read directly on the psi gauge, with automatic condensate bleed via the differential drain.
Start with size and port: the 400 size with a 3/8 in PT port suits lines running at moderate-to-high air demand; step up or down through 200/300/400/600 as your flow requirement changes. Next, choose the drain: this unit uses the differential-pressure drain (default), which discharges condensate automatically during flow, while automatic (code A) and manual (code M) drains are available. The 40 um element is standard here; specify code W for a 5 um element where finer filtration is needed. The embedded square gauge is fitted in psi on this model; MPa and bar scales and an external round gauge are options. PT is the standard thread, with G (BSPP) and NPT available to order, and a bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated figure, so we cannot quote you a rated flow number. Send us your application details and we will confirm the sizing and datasheet figures 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 GFR series as performance curves rather than a single rated figure, so we do not quote a rated flow number. Send us your line pressure, downstream demand and application details, and we will confirm the sizing against the datasheet curves before you order.
This model uses the differential-pressure drain, the GFR default: collected condensate is discharged automatically when the air flow through the unit creates the required pressure differential, with no operator action needed. If your application has low or intermittent flow, an automatic drain (code A) or a manual drain (code M) can be ordered instead.
