AirTAC GFR400-15 Filter Regulator (GFR40015MJF1)
The AirTAC AirTAC GFR400-15 Filter Regulator (GFR40015MJF1) 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 PT1/2" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 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 GFR400-15 Filter Regulator (GFR40015MJF1)
The AirTAC GFR400-15MJF1 is a filter regulator: filtration and pressure regulation combined in a single body. This 400-size unit carries a 1/2 in PT port, a manual-drain bowl in polycarbonate, the standard 40 um filter element, and the embedded square pressure gauge reading in MPa (the F gauge option). With the J option no mounting bracket is included.
This is a genuine AirTAC part from the GFR series, available in sizes 200, 300, 400 and 600 with a choice of ports, drains, 40 um or 5 um elements, gauge styles and G or NPT thread options. Maximum inlet pressure is 1.0 MPa (145 psi); with the manual drain fitted the regulated output spans 0.05-0.9 MPa (7-130 psi). Operating temperature is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so we confirm the datasheet 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 0.05 - 0.9 MPa (7 - 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 GFR400-15 Filter Regulator (GFR40015MJF1)
| GFR400 | G-series filter regulator, 400 body — sets the port range. |
|---|---|
| 15 | Port size PT1/2". This body offers 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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 GFR400-15 Filter Regulator (GFR40015MJF1) Is Used
Plant air drop for general pneumatic tooling
Sits at the air drop feeding impact wrenches, nut runners and other pneumatic hand tools at a plant workstation, providing filtered air at a set working pressure.
Belt conveyor take-up and gate actuators
Conditions the supply to tensioning units and gate cylinders on a belt conveyor system, keeping actuator pressure steady along the line.
Machine builder OEM air-prep panels
Serves as the compact filter-regulator stage on an OEM machine's air-prep panel, with the embedded square gauge giving a clear set-point readout on the panel face.
Is the AirTAC GFR400-15 Filter Regulator (GFR40015MJF1) the Right Unit?
Choose the 400 size for a 1/2 in connection, stepping to 300 or 600 as your flow demand and pipework dictate. The manual drain gives the widest 0.05-0.9 MPa (7-130 psi) adjustment range but needs periodic bleeding; automatic or differential-pressure drain versions suit unattended installations. This unit carries the standard 40 um element; pick the W variant for the fine 5 um grade. The F option here is the embedded square gauge in MPa; the round external gauge is the alternative. PT is the standard thread, with G (BSPP) and NPT orderable, and no bracket is fitted.
Flow is published as curves rather than a single rated figure, so ask us to confirm sizing from the datasheet before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1/2" 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 0.05 - 0.9 MPa (7 - 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 GFR400-15 Filter Regulator (GFR40015MJF1) FAQ
No single rated flow is published for this unit; AirTAC provides performance as flow curves. Send us your operating pressures and air demand and we will confirm the datasheet figures and check that the 400 size, 1/2 in port suits your line.
F selects the embedded square pressure gauge with an MPa scale, built into the unit, instead of the external round gauge fitted to C-coded versions. The rest decodes as: 400 size, 1/2 in PT port, manual drain, standard 40 um element, and no bracket (J).
