Airtac GFR Filter Regulator GFR400C15JF1WK
The AirTAC GFR Filter Regulator GFR400C15JF1WK 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 GFR400C15JF1WK
The AirTAC GFR400C15JF1WK is a genuine AirTAC filter regulator: filtration and pressure regulation combined in a single 400-size body. This configuration carries a 1/2 inch PT port, a fine 5 um filter element, a differential-pressure drain that bleeds collected condensate as pressure differential builds, an embedded square pressure gauge scaled in MPa, and a built-in check valve that blocks reverse flow through the unit. It is shipped without a mounting bracket (J), so order one separately if panel or wall fixing is needed.
As a genuine AirTAC part, the GFR400 series shares the G-series platform: 200, 300, 400 and 600 sizes, 40 um standard or 5 um (W) filtration, differential-pressure, automatic or manual drains, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Max working pressure is 1.0 MPa (145 psi) and working temperature is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask 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.
Model Code: Airtac GFR Filter Regulator GFR400C15JF1WK
| 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 GFR400C15JF1WK Is Used
CNC machining center air supply
Points the filtered, regulated feed to tool-changer and clamping cylinders on a machining cell, with the 5 um element guarding against fine particle carryover and the check valve holding the regulated setting if upstream supply dips.
Carton-forming and sealing station
Feeds the vacuum generators and flap-folding cylinders of a packaging machine from a single 1/2 inch drop, keeping one stable pressure setting for the whole station instead of tuning individual regulators.
Robotic gripper manifold
Serves as the single conditioning point ahead of a robot cell's gripper and end-effector valves, where the MPa-scaled gauge gives a quick visual setpoint check during commissioning and changeover.
Is the Airtac GFR Filter Regulator GFR400C15JF1WK the Right Unit?
Size 400 with a 1/2 inch PT port is a mid-large step in the G-series range; move to 300 for smaller lines or 600 for high-demand headers, always matched to your pipe size and demand curve rather than a single flow number. Drain options are differential-pressure (this model), automatic (A) for unattended condensate removal, or manual (M). The 5 um (W) element suits instrumentation and precision actuators; the standard 40 um element protects general cylinders and valves. The square gauge here reads in MPa; psi or bar scales and an external round gauge are alternatives.
Thread is PT as standard, with G (BSPP) and NPT available as ordering options. A mounting bracket (J = not fitted on this unit) is offered across the family. Because flow is published as curves, not a single rated figure, send us your line pressure and demand and we will confirm sizing against the datasheet before you order.
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 GFR400C15JF1WK FAQ
AirTAC publishes flow for the G-series as characteristic curves, not as a single rated number, so we do not quote one here. Tell us your inlet pressure, set pressure and air demand, and we will confirm the flow figures from the datasheet for this exact model on request.
The K in the code means a reverse/check valve is fitted at the unit. It blocks reverse flow through the regulator, which helps hold the downstream setting if the upstream supply is momentarily interrupted. The same GFR400 body is available without it (blank position) if you do not need this function.
