Airtac GFR Filter Regulator GFR400C10MF1
The AirTAC GFR Filter Regulator GFR400C10MF1 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 GFR400C10MF1
The GFR400C10MF1 is an AirTAC G-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in one body. This configuration is the 400 size with a 3/8 in PT port, a 40 um standard filter element, and a manual drain that you open by hand to empty the bowl. An embedded square gauge on an MPa scale shows the regulated pressure, the adjustment range is 0.05-0.9 MPa (7-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C, non-freezing. The 400-size bowl is polycarbonate (PC).
This is a genuine AirTAC part from the G-series 200/300/400/600 size range, with catalogue options across port sizes, thread types (PT standard, with G and NPT as orderable variants), drain types, filter grades and gauges. Series flow is published as performance curves rather than a single rated figure, so we confirm sizing and full 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.

| GFR400 | G-series filter regulator, 400 body — sets the port range. |
|---|---|
| C1 | Port size See datasheet. This body offers 10 = PT3/8", 15 = PT1/2". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| (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.

Where the Airtac GFR Filter Regulator GFR400C10MF1 Is Used
CNC machining centre air feed
Filter and regulate the shop-air supply feeding a CNC machining centre's tool-change and clamping circuits, with the bowl emptied by hand on the daily maintenance round.
Cartoning machine actuation
Supply filtered, regulated air to the pick-and-place cylinders and sealing heads of a cartoning line, holding a steady setpoint read off the embedded MPa gauge.
Pneumatic press clamping
Prep the air feeding the clamping cylinders on a bench-mounted pneumatic press, with the operator draining the bowl manually at end of shift.
Is the Airtac GFR Filter Regulator GFR400C10MF1 the Right Unit?
Move up or down the 200/300/400/600 size and port ladder as your line flow demands; the 400 size with a 3/8 in PT port sits in the mid-range of the family. Drain choice is manual (this unit), automatic, or the differential-pressure default - manual drain gives the wider 0.05-0.9 MPa (7-130 psi) regulator range. Element grade is the 40 um standard here; the W code orders the 5 um fine grade. The square gauge reads in MPa; psi and bar scales and an external round gauge are catalogue options. Thread is PT as standard with G (BSPP) and NPT orderable, and the J variant omits the mounting bracket. Flow for this series is published as curves, not a single rating - 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 GFR400C10MF1 FAQ
AirTAC publishes G-series capacity as performance curves rather than a single rated-flow figure, so we do not quote one number here. Send us your line pressure and air demand and we will confirm the correct sizing and the curve data from the datasheet on request.
The manual drain suits lines where the bowl is emptied as part of a scheduled maintenance routine; automatic (A) and differential-pressure (blank) variants discharge condensate themselves. Manual drain also gives the full 0.05-0.9 MPa (7-130 psi) regulator adjustment range on this family.
