Airtac GFR Filter Regulator GFR400C10MJC1
The AirTAC GFR Filter Regulator GFR400C10MJC1 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 GFR400C10MJC1
The GFR400C10MJC1 is an AirTAC G-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in one body, with a drain bowl but no lubricator. This 400-size unit carries a 3/8 in PT port, a manual drain, a standard 40 um filter element, 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), and maximum working (inlet) pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the G series, which spans 200, 300, 400 and 600 sizes with port sizes from 1/8 in to 1 in, drain choices, 5 um (W) filtration, G and NPT thread options and gauge variants. Rated flow for GFR units is published as curves rather than a single figure, so contact us and we will confirm the datasheet figures for your application 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.

|---|---|
| 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. |

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 GFR400C10MJC1 Is Used
Pneumatic press supply
Filter and regulate the air feeding a bench pneumatic press or riveting tool, with the round MPa gauge letting an operator verify set pressure at a glance and the manual drain emptied during shift checks.
Packaging machine air preparation
Clean and set the supply pressure for carton-sealing and labelling stations on a packaging line, where a stable regulated pressure keeps cylinder strokes consistent between batches.
Control panel air feed
Condition the air going to solenoid valves and pilot circuits in a machine control cabinet, protecting components from water and debris while holding the pressure the valve stack was set up for.
Is the Airtac GFR Filter Regulator GFR400C10MJC1 the Right Unit?
Size 400 with a 3/8 in PT port sits mid-range in the G series: step up to 600 for larger ports and more flow, or down to 300/200 for compact circuits. The M code means manual drainage - choose the blank (differential-pressure) or A (automatic) drain code if you want condensate removal without opening the bowl by hand. Filter grade is the standard 40 um element; specify W if you need 5 um. This configuration includes the external round gauge on an MPa scale (square embedded and other scales are catalogue options), omits the mounting bracket, and uses PT thread as standard with G (BSPP) and NPT available to order.
Flow for G-series filter regulators is published as curves, not a single rated number, so please 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 GFR400C10MJC1 FAQ
AirTAC publishes flow for G-series filter regulators as performance curves rather than a single rated figure, so we do not quote one number here. Send us your application details and we will confirm the datasheet flow figures for this 400-size, 3/8 in PT unit on request.
The M code in GFR400C10MJC1 specifies manual drainage: condensate collects in the PC bowl and is released by hand, which suits stations visited regularly by maintenance. The same 400-size body is available with the default differential-pressure drain or an automatic (A) drain; note that with manual drainage the regulator adjustment range is 0.05-0.9 MPa (7-130 psi).
