AirTAC GFR400-15 Filter Regulator (GFR40015MNWK)
The AirTAC AirTAC GFR400-15 Filter Regulator (GFR40015MNWK) is a genuine G-series filter regulator: water separation, 5 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 (GFR40015MNWK)
The AirTAC GFR400-15MNWK combines filter and regulator in one body, with a reverse/check valve (K) fitted to block backflow. The W suffix selects the finer 5 um filter element in place of the 40 um standard. This size 400 unit has a 1/2 in PT port, a manual drain bowl, and no gauge fitted. Maximum working pressure is 1.0 MPa (145 psi); the regulator adjusts 0.05-0.9 MPa (7-130 psi) on the manual-drain version.
This is a genuine AirTAC part. G-series filter regulators span sizes 200, 300, 400 and 600 with PT (standard), G or NPT threads, a choice of drain type, 40 um or 5 um elements, gauge options and the optional reverse/check valve. Flow is published as curves, not a single rating, so ask 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 0.05 - 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 (GFR40015MNWK)
| 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. |
| (blank) | Mounting bracket included. |
| N | No pressure gauge (N). |
| (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. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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

- GFR300PT1/4" - PT1/2"
- 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 GFR400-15 Filter Regulator (GFR40015MNWK) Is Used
Robotic gripper circuits
Filtering and regulating air to the gripper and tool-change circuits on a robotic handling cell, with the check valve preventing backflow through the supply when the line is vented.
Food and beverage line actuators
Conditioning the air supply to reject gates, capper heads and conveyor stops on a bottling line, where a set pressure and a 5 um element protect the control valves.
Maintenance workshop ring main
A point-of-use filter regulator on a workshop ring main feeding air tools and lifting bags, holding a fixed working pressure with clean, 5 um-filtered air.
Is the AirTAC GFR400-15 Filter Regulator (GFR40015MNWK) the Right Unit?
Take size 400 with the 1/2 in PT port for mid-to-large plant circuits, stepping to 600 for the biggest mains or 300/200 for lighter lines. K adds the reverse/check valve for circuits that must not backflow; W fits the 5 um element where the 40 um standard grade is not fine enough. The manual drain (M) calls for a scheduled hand-drain - choose an automatic-drain suffix where the bowl is out of reach. No gauge is fitted (N), with gauge options available to order. Thread is PT standard, G and NPT to order; bracket included.
Flow in this series is published as curves rather than a single rated number, so send us your air demand and pressure and we will confirm sizing from the datasheet before you order.
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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC GFR400-15 Filter Regulator (GFR40015MNWK) FAQ
No single rated flow is quoted for this series: AirTAC publishes G-series flow as performance curves. We will confirm the datasheet figures and check the sizing against your required flow and pressure on request before you order.
W changes the filter element from the 40 um standard to the finer 5 um grade, and K fits a reverse/check valve to block backflow through the unit. Everything else is the same: size 400, PT 1/2 in port, manual drain, no gauge fitted, standard regulator type.
