The AirTAC GFR Filter Regulator GFR400C10MJC1W 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 GFR400C10MJC1W is an AirTAC G-series filter regulator combining water and particulate filtration with pressure regulation in one body, with a drain bowl and no lubricator. The W code fits the finer 5 um filter element instead of the 40 um standard. This 400-size unit has a 3/8 in PT port, a manual drain, an external round pressure gauge with MPa scale, and no mounting bracket (J code). With manual drainage the regulator adjustment range is 0.05-0.9 MPa (7-130 psi); maximum working (inlet) pressure is 1.0 MPa (145 psi) and operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the G series, available in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, and options covering drain type, filter grade, gauge style and scale, and PT, G or NPT threads. Flow is published as curves rather than one rated figure, so contact us and we will confirm the datasheet figures on request.

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.

Deliver finely filtered, regulated air to analytical instruments and sample-handling actuators in a lab, where the 5 um element guards against particulates reaching sensitive components.
Supply clean regulated air to air bearings, air tables and blowing nozzles on handling equipment, where coarser filtration could pass debris into small orifices.
Condition air for spray guns and coating applicators on a finishing line, using 5 um filtration downstream of the main dryer and the round gauge to hold the set delivery pressure.
Specify this code when your application needs the finer 5 um filtration (W) - for example to protect sensitive downstream components - rather than the standard 40 um element; the trade-off is a denser element, so confirm sizing with us. The 400 size and 3/8 in PT port suit mid-range circuits; move to 600 or 300 depending on the flow and port step you need. Manual drain (M) means condensate is released by hand; A (automatic) and the blank differential-pressure drain are the other catalogue choices. Round MPa gauge is fitted here, with square embedded gauges and other scales available; the bracket is omitted (J) but optional, and G or NPT threads can be ordered instead of PT.
Flow data for this series is published as curves, not a single rating, so ask us to confirm sizing against your application 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, not a single rated number, and the 5 um element in this W version is a factor in sizing. Share your application flow requirement with us and we will confirm the datasheet figures for this 400-size, 3/8 in PT unit on request.
The W code fits a 5 um element for finer particulate removal, suited to sensitive components such as precision valves, nozzles and instruments; the blank code is the standard 40 um grade for general plant air. Both are offered across the G-series filter regulator range, so pick the grade that matches what your downstream equipment tolerates.
