Airtac GFR Filter Regulator GFR400C10AJC1WK
The AirTAC GFR Filter Regulator GFR400C10AJC1WK 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 GFR400C10AJC1WK
GFR400C10AJC1WK is an AirTAC G-series filter regulator that combines two orderable options: the 5 um (W) filter element for finer particulate removal and a reverse/check valve (K) that stops downstream air flowing back toward the supply side. Otherwise it is the standard filter-regulator configuration: 400 size, PT3/8 port, automatic drain, external round gauge scaled in MPa, no mounting bracket, maximum inlet pressure 1.0 MPa (145 psi), adjustment range 0.15-0.9 MPa (20-130 psi) with the automatic drain, working temperature -5 to 70 C, and a PC (polycarbonate) bowl at the 400 size.
This is a genuine AirTAC part. The G-series filter regulator range covers 200 to 600 sizes and ports from 1/8 to 1 inch, with the W element, K check valve, three drain types, square or round gauges in MPa, psi or bar scales, and G (BSPP) or NPT threads all available within the family. Flow is published as curves, not a single rated figure, so we confirm flow 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.
Model Code: Airtac GFR Filter Regulator GFR400C10AJC1WK
| 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 GFR400C10AJC1WK Is Used
Coating line nozzle circuit
Regulated, 5 um-filtered air to the spray nozzles of a coating line, with the check valve keeping product-side air from working back through the unit if the supply drops.
Screw-machine air clamps
Supplying the pneumatic clamps on a bar-fed screw machine, where the 5 um element protects the clamp valves and the check valve isolates the clamped workpiece from upstream loss.
High-speed sorting gates
Air preparation for the diverter gates and stopper cylinders of a high-speed sorting line, where rapid cycling and an unattended duty point justify the 5 um element, automatic drain and check valve together.
Is the Airtac GFR Filter Regulator GFR400C10AJC1WK the Right Unit?
This code pairs the two options you will meet in the G series: W for the 5 um element and K for the reverse/check valve - pick it when the circuit needs both finer filtration and isolation from supply-side backflow. Size from the port and demand: 400 size with a 3/8 inch PT port is the step above the 300 series, and since AirTAC publishes flow only as curves, ask us to confirm the 400 size against your application before ordering. The automatic drain suits unattended duty at a 0.15-0.9 MPa (20-130 psi) adjustment range; manual-drain versions reach 0.05-0.9 MPa (7-130 psi). The external round gauge reads in MPa, and square-gauge, psi and bar scales exist. Thread is PT as standard with G (BSPP) and NPT as catalogue options; J means no bracket is fitted, so order one if you mount to a panel.
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 GFR400C10AJC1WK FAQ
We do not quote a rated flow figure, because AirTAC publishes G-series performance as curves rather than a single rating. Tell us your line pressure and required flow and we will confirm sizing from the datasheet curves for the 400 size and 3/8 inch port before you order.
PT is the standard thread for this code, and G (BSPP) as well as NPT are catalogue thread options within the same G-series family - state the thread when ordering. The rest of this configuration stays as decoded: 400 size, 3/8 inch port, automatic drain, 5 um element, external round MPa gauge, check valve, PC bowl, no bracket.
