The AirTAC GFR Filter Regulator GFR400C10AC1 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 GFR400C10AC1 is an AirTAC G-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single body. This configuration is the size 400 unit with a 3/8 in PT port, an automatic drain that purges condensate from the polycarbonate bowl without operator attention, the standard 40 um filter element, and an external round pressure gauge reading in MPa. With the automatic drain, the regulation range is 0.15-0.9 MPa (20-130 psi); maximum inlet pressure is 1.0 MPa (145 psi) and operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The G-series filter regulator comes in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options including manual or automatic drains, a 5 um element (W), G (BSPP) or NPT threads, a no-bracket (J) variant, no-gauge (N) variants and a check-valve (K) variant. Flow is published as performance curves rather than a single rated figure, so ask us and we will confirm the datasheet numbers 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.

| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

Regulated, water-free air for the tool changer and clamping cylinders on a machining centre; the automatic drain keeps condensate out of the bowl on a continuously running compressor ring main.
Feeding the cylinder-driven taping head on a packaging conveyor; the external MPa gauge lets line staff verify the set pressure at a glance during product changeover.
Dropping water and pipe scale out of the supply and holding a steady atomizing pressure at a spray booth - a filter regulator only, with no oil mist added downstream.
Step up or down through the size range (200/300/400/600) against the flow your line needs - the 400 size here carries a 3/8 in port, and larger sizes give larger ports and more flow. Drain choice: automatic (this code), manual (M), or the default differential-pressure type. Element: 40 um standard, or 5 um (W) where finer protection matters. This unit is supplied with an external round MPa gauge (C1); embedded square gauges and psi or bar scales are available elsewhere in the family. Thread: PT is the standard, with G (BSPP) and NPT as catalogue options, and the mounting bracket is included (order J to delete it). Flow is published as curves, not a single rating - send us your flow and pressure requirement and we will confirm sizing against the application 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 G-series flow as performance curves rather than a single rated figure, so we do not quote one number here. Tell us your required flow and working pressure and we will confirm the datasheet curve data for this exact model on request.
A is the automatic drain, which purges collected condensate from the bowl without operator attention, and C1 is the external round pressure gauge with an MPa scale. Related options in the family are M (manual drain), W (5 um element), N (no gauge), K (check valve) and G or T thread variants.
