The AirTAC GFR400C10F2 AirTAC Filter Regulator, PT3/8, Square Gauge 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 See datasheet 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 GFR400C10F2 is a filter regulator: water and particulate removal plus downstream pressure regulation combined in a single size-400 body with a PT3/8 (3/8 in) port. This configuration carries the standard 40 um filter element with a differential-pressure drain, a standard-type regulator adjustable from 0.15-0.9 MPa (20-130 psi), and a fitted square gauge reading in psi. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). At size 400 the polycarbonate bowl keeps the condensate and element visible for inspection.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options include a 5 um element (code W), automatic or manual drains, G (BSPP) or NPT threads, alternative gauge scales, and a low-pressure regulator type. Published flow data appears as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application before you order.

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.

Clean, regulated air for tool-clamp and chip-clearing cylinders on a CNC machining centre: the 40 um element strips water and swarf-laden particles from the shop ring main, while the regulator holds a steady setting at the machine drop.
On a beverage bottling line, the conveyor stop-gates and pusher cylinders need air that is both dry enough to avoid sticking valves and steady enough for repeatable stroke timing; this filter regulator sits at the line drop to do both jobs in one body.
A light pneumatic press or clamping fixture in an assembly plant depends on consistent set pressure for repeat part quality; the fitted psi gauge lets operators verify the setting at a glance while the differential drain keeps condensate off the bowl bottom.
Step through the decodable choices in order. First, size and port: this unit is size 400 with a PT3/8 port; step up or down (200/300/400/600, ports 1/8 in to 1 in) to match the air demand of the line, and we will confirm the flow curve against your consumption before you order. Second, drain: differential-pressure (this configuration), automatic (code A) for unattended duty, or manual (code M) where you want a deliberate drain action. Third, filtration grade: 40 um standard here, or 5 um (code W) for finer protection. Fourth, gauge: the fitted square gauge reads psi; MPa and bar scales and an external round gauge are alternatives. Thread is PT as standard with G (BSPP) and NPT as order options, and a mounting bracket is included. Because flow is published as curves rather than a single rating, send us your application details and we will confirm sizing 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 G-series flow as performance curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and air consumption and we will confirm the datasheet curve for this size-400 unit on request before you order.
The differential-pressure drain (the default) dumps condensate when the pressure drop across the element rises. Choose automatic drain (code A) for unattended or hard-to-reach installations, or manual drain (code M) where you want a deliberate drain action as part of a maintenance routine. All three are catalogue options across the GFR range.
