Airtac GFR Filter Regulator GFR400C10MJC1K
The AirTAC GFR Filter Regulator GFR400C10MJC1K 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 GFR400C10MJC1K
The GFR400C10MJC1K is an AirTAC G-series filter regulator with a reverse (check) valve fitted: filtration and pressure regulation in one body with a drain bowl, and no lubricator. The K code adds the check valve so downstream pressure is held if the upstream supply is lost. This 400-size unit has a 3/8 in PT port, manual drain, standard 40 um filter element, external round pressure gauge on an MPa scale, and no mounting bracket (J code). Manual drainage gives a 0.05-0.9 MPa (7-130 psi) regulator adjustment range, with 1.0 MPa (145 psi) maximum working pressure and -5 to 70 C operation.
This is a genuine AirTAC part from the G series, offered in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, plus drain, filter grade (5 um W option), thread (G, NPT, PT) and gauge options. Flow is published as curves rather than a single rated figure; contact us and we will confirm 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.

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 GFR400C10MJC1K Is Used
Pilot air for process valves
Filter, regulate and hold pilot pressure to a bank of pneumatic process valves, where the fitted check valve keeps the pilot circuit pressurised during upstream supply dips.
Conveyor stopper and gate actuation
Supply filtered, regulated air to stoppers, gates and pushers along a conveyor line, with the manual drain handled during planned stops and the gauge confirming set pressure.
Workholding fixture supply
Feed clamping fixtures on a machining fixture panel, where steady regulated pressure is needed to hold parts and the check valve supports the circuit if shop air pressure drops.
Is the Airtac GFR Filter Regulator GFR400C10MJC1K the Right Unit?
Choose this code when you want the 400-size, 3/8 in PT filter regulator with the K option - a built-in reverse/check valve that holds downstream pressure against backflow or supply loss - alongside manual drainage, the standard 40 um element, the round MPa gauge, and no bracket. If the check valve is not wanted, the same unit exists without the K suffix. Drain type, 5 um (W) filtration, gauge style and scale, and G or NPT thread instead of the PT standard are all catalogue choices.
Because G-series flow data is published as curves, not a single rating, ask us to confirm sizing for your flow requirement 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 GFR400C10MJC1K FAQ
AirTAC does not publish a single rated flow figure for G-series filter regulators - flow is given as performance curves. Tell us your application and required flow, and we will confirm the datasheet curve figures for this 400-size, 3/8 in PT unit on request before you order.
K specifies that a reverse (check) valve is fitted, so air flows downstream through the filter regulator but backflow is blocked and downstream pressure is retained if the upstream supply fails. The identical unit without the check valve is ordered as GFR400C10MJC1.
