Airtac GFR Filter Regulator GFR400C10JC1K
The AirTAC GFR Filter Regulator GFR400C10JC1K 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 GFR400C10JC1K
GFR400C10JC1K is an AirTAC G-series filter regulator: filtration and pressure regulation combined in a single body, with a drain bowl but no lubricator. This size 400 configuration uses a 3/8 in PT port, the standard 40 um filter element and a differential-pressure drain, and the K code adds a reverse (check) valve so air cannot flow backwards through the unit. The C1 code specifies an external round pressure gauge with MPa scale, and J means no mounting bracket is included. With this drain type the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi) at a maximum working pressure of 1.0 MPa (145 psi). The medium is compressed air only, service temperature is -5 to 70 C (non-freezing), and the 400-size bowl is PC (polycarbonate).
This is a genuine AirTAC part. The same GFR family spans sizes 200 to 600 with ports from 1/8 to 1 in, and lets you specify drain type (differential-pressure, automatic or manual), element grade (40 um standard, 5 um optional), gauge style and scale, the check valve option, thread (PT standard; G and NPT as ordered variants) and bracket. Flow for this series is published as curves rather than a single rating, so ask us to confirm the datasheet figures against 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.
Size Class

- GFR400PT3/8" - PT1/2"
- GFR600PT3/4" - PT1"
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 GFR400C10JC1K Is Used
Compressor room branch line
Dropping pressure on a branch feeding a secondary circuit in the compressor room, with the fitted check valve blocking backflow toward the supply when the upstream header is vented.
Machining fixture clamp circuit
Feeding a dedicated clamp circuit on a machining fixture at its own set pressure, with the check valve preventing reverse flow through the unit if the downstream side remains pressurized.
Conveyor diverter gates
Supplying pneumatically actuated diverter and stopper gates along a conveyor line, keeping supply dips from back-feeding the regulator during venting or shutdown.
Is the Airtac GFR Filter Regulator GFR400C10JC1K the Right Unit?
Choose this K version over the plain GFR400C10JC1 when the downstream side can stay pressurized or the upstream line can be vented, and you want backflow through the unit blocked. Everything else is the same ordering decision set: size step 200/300/400/600 for port and duty (here 400 on a 3/8 in PT port), drain type (this model is differential-pressure; automatic and manual exist), element grade 40 um standard or 5 um with W, and gauge style and scale (here external round, MPa; square embedded, psi and bar scales are options). Thread is PT as standard, with G (BSPP) and NPT as ordered variants, and J omits the bracket. Flow is published as curves, not a single rating - ask us to confirm sizing against the datasheet 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 GFR400C10JC1K FAQ
For the GFR400 size, flow is published as performance curves rather than a single rated figure, so we do not quote one number. Share your inlet pressure, set pressure and flow requirement and we will confirm the sizing against the datasheet on request.
It fits a reverse (check) valve in the unit, so air cannot flow backwards through the filter regulator if the downstream side stays pressurized or the upstream line is vented. Everything else in the code - the 3/8 in PT port, 40 um element, MPa round gauge, no bracket - is identical to the plain version.
