Airtac GFR Filter Regulator GFR400C10MJF1W
The AirTAC GFR Filter Regulator GFR400C10MJF1W 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.

About the Airtac GFR Filter Regulator GFR400C10MJF1W
GFR400C10MJF1W is an AirTAC G-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at your setpoint. This 400-size unit is drilled for PT 3/8 in ports and carries the finer 5 um filter element (W code), suited to applications that need cleaner air than the standard 40 um grade. It has a manual drain on the PC (polycarbonate) bowl, is supplied without a mounting bracket (J code), and the embedded square gauge reads in MPa. With the manual drain, the regulator adjustment range is 0.05-0.9 MPa (7-130 psi); maximum working pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part from the 200/300/400/600 G-series range. Elsewhere in the series you can order G (BSPP) or NPT threads, automatic or differential-pressure drains and a check-valve option. The temperature range is -5 to 70 C, non-freezing. Flow for this series is published as curves rather than a single rating, so ask us to confirm the datasheet figure 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.

Where the Airtac GFR Filter Regulator GFR400C10MJF1W Is Used
Lab actuator supply
Conditions air for the small actuators and sample-handling cylinders on a laboratory automation bench, where the 5 um element keeps finer debris away from compact valves.
Paint booth atomizing air
Feeds filtered, regulated atomizing air to spray nozzles in a finishing booth, with the manual drain bled before each batch to protect the nozzle circuit.
Pick-and-place grippers
Prepares the supply for vacuum ejectors and gripper cylinders on a pick-and-place cell, holding a stable setpoint through repeated fast cycles.
Is the Airtac GFR Filter Regulator GFR400C10MJF1W the Right Unit?
Size 400 with a 3/8 in port sits above the 300/1/4 in step and below 600/1/2 in - choose the step from the flow your line needs, not the pipe size alone. The W code selects the 5 um element instead of the standard 40 um grade, so reserve it for points that need finer air and treat it as a polishing stage. The manual drain suits an attended station bled on a schedule; automatic and differential-pressure drain codes exist for hard-to-reach mounts. The square MPa gauge is built in, thread can be ordered as G (BSPP) or NPT rather than PT, and the J code means you supply your own bracket. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (See datasheet here)
- ✓ Element 40 µm or 5 µm
- ✓ Drain sets the regulating band
- ✓ Gauge fitted, shape and scale
- ✓ Thread PT, G (BSPP) or NPT
- ✓ Oil needed downstream? Use GFC instead
Installation & Maintenance Notes
- check Mount vertically, bowl down, following the airflow arrow.
- check One body does the filtering and the regulating — no separate regulator needed.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Adjust only within 0.15 - 0.9 MPa (20 - 130 psi).
- check Drain condensate before the bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
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 GFR Filter Regulator GFR400C10MJF1W FAQ
AirTAC publishes flow for the G series as curves, not as a single rated number, so we do not quote one figure. Send us your required flow and working pressure and we will confirm the datasheet curve for this 400-size, 3/8 in unit against your application before you order.
The W code fits a 5 um element instead of the standard 40 um grade, so choose it where the downstream valves, nozzles or ejectors are sensitive to finer particles, typically as a polishing stage after coarser treatment. The rest of the decode is unchanged: size 400, PT 3/8 in ports, manual drain, square MPa gauge, no bracket.
