Airtac GFR Filter Regulator GFR400C10MJF1
The AirTAC GFR Filter Regulator GFR400C10MJF1 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 GFR400C10MJF1
GFR400C10MJF1 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, carries the standard 40 um filter element, and has a manual drain on the PC (polycarbonate) bowl. It is supplied without a mounting bracket (J code), and the embedded square gauge reads in MPa. Because the drain is manual, 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, a finer 5 um element (W code) 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 GFR400C10MJF1 Is Used
Pneumatic clamping fixture
Feeds filtered, regulated air to the hold-down cylinder on a machining fixture, with the manual drain bled before each shift so condensate never reaches the clamp valve.
Packaging line gate cylinders
Conditions the air supply to the gate and divert cylinders on a carton packaging line, keeping dirt and water out of the directional valves that index each carton.
Assembly bench air tools
Prepares the supply for inline drivers and torque tools at a bench assembly cell, with the setpoint held steady while operators change between stations.
Is the Airtac GFR Filter Regulator GFR400C10MJF1 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 manual drain here suits an attended station bled on a schedule; where the unit is hard to reach, pick the automatic or differential-pressure drain code instead. The standard element is 40 um; the W code gives 5 um for finer filtration downstream of a coarser stage. 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 GFR400C10MJF1 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 M code means the PC bowl is bled by hand, which suits attended stations on a maintenance routine. If the unit will be mounted where it cannot easily be reached, the same 400-size filter regulator is available with an automatic or differential-pressure drain - ask us for that code.
