Airtac GFR Filter Regulator GFR400C10JC1WK
The AirTAC GFR Filter Regulator GFR400C10JC1WK 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 GFR400C10JC1WK
GFR400C10JC1WK 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 and the W code selects the finer 5 um filter element instead of the 40 um standard, with a differential-pressure drain. 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 with W), the check valve option, gauge style and scale, 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.

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 GFR400C10JC1WK Is Used
Spray booth coating line
Regulating filtered air to automated spray nozzles on a coating line, with the 5 um element protecting the nozzles and the check valve preventing backflow when the branch is vented.
CNC tool changer air prep
Feeding the tool-clamp and changer circuit of a CNC machining center, where the finer 5 um grade suits the close-tolerance cylinders and the check valve holds the branch against supply-side backflow.
Instrument air takeoff panel
Supplying a panel of pneumatic instruments and transducers from a plant air header, combining 5 um protection, a stable regulated pressure and reverse-flow isolation in one unit.
Is the Airtac GFR Filter Regulator GFR400C10JC1WK the Right Unit?
This code stacks two real options on the same 400-size, 3/8 in PT unit: W for the 5 um element (instead of the 40 um standard) and K for the reverse (check) valve that blocks backflow through the body. Drain is differential-pressure here; automatic and manual versions exist if your duty needs them. Gauge is the external round type with MPa scale via C1 - the embedded square gauge and psi or bar scales are catalogue options, and N deletes the gauge. 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 GFR400C10JC1WK FAQ
There is no single rated figure to quote: AirTAC publishes flow for the GFR400 size as performance curves. Send us your inlet pressure, set pressure and required flow and we will confirm the sizing against the datasheet on request.
PT is the standard thread for this unit as coded. G (BSPP) and NPT versions are catalogue options you order as separate variants - they are specification choices, not conversions to make on the unit itself. Pick the one matching your fittings and ask us to quote that code.
