AirTAC GFR400-10 Filter Regulator (GFR40010MNWK)
The AirTAC AirTAC GFR400-10 Filter Regulator (GFR40010MNWK) 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 PT3/8" 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 GFR400-10 Filter Regulator (GFR40010MNWK)
The AirTAC GFR40010MNWK is a G-series filter regulator: filtration and pressure regulation combined in one body. This 400-size unit carries a 3/8in NPT port, a manual drain on the polycarbonate bowl, a fine 5 um filter element, a built-in check (reverse-flow) valve, and no gauge. The manual drain lets an operator bleed collected condensate by hand, and the 5 um element suits lines where finer particulate control matters; regulation spans 0.05-0.9 MPa (7-130 psi).
This is a genuine AirTAC part. The G series spans sizes 200, 300, 400 and 600 with a full choice of ports, threads (PT standard, G and NPT as catalogue options), drain types, filter grades and gauge arrangements. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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 GFR400-10 Filter Regulator (GFR40010MNWK)
| GFR400 | G-series filter regulator, 400 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". 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.

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 GFR400-10 Filter Regulator (GFR40010MNWK) Is Used
Machine-shop pneumatic workholding
Feeding clamps and vise cylinders on CNC fixtures, where the 5 um element keeps fine particulate out of spool valves and the regulator holds repeatable clamping pressure.
Packaging line air cylinders
Supplying pick-and-place and carton-sealing cylinders on a packaging conveyor, with the check valve holding downstream pressure during momentary supply dips.
Assembly-station air tools
Conditioning supply air at a bench assembly station running impact drivers and nutrunners, with manual draining built into shift-start housekeeping.
Is the AirTAC GFR400-10 Filter Regulator (GFR40010MNWK) the Right Unit?
Work up from your required flow: size 200 is the smallest step and 600 the largest, with the 3/8in port on this 400 body sitting mid-range - if your line sits between sizes, step up rather than down. Choose the drain to match access: manual suits attended installations where an operator drains the bowl, while automatic or differential-pressure drains suit unattended duty. The 5 um (W) element is the finer option against the 40 um standard. This code has no gauge (N) - gauges can be ordered on other variants. NPT is specified here; PT is the standard thread and G (BSPP) is available to order.
Flow for the G series is published as curves, not a single rated figure, so we cannot quote one number honestly. Send us your application details and we will confirm the datasheet and sizing against the curves before you order.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" 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 GFR400-10 Filter Regulator (GFR40010MNWK) FAQ
AirTAC publishes flow for the G series as curves, not as a single rated figure, so we do not quote one number. Maximum working pressure is 1.0 MPa (145 psi). Send us your application and we will confirm the datasheet and check the sizing against the curves on request.
A manual drain means an operator opens the drain to discharge collected condensate, which suits attended installations; with a manual drain the regulation range is 0.05-0.9 MPa (7-130 psi). The K designates a fitted reverse (check) valve, which prevents downstream backflow through the unit. The W gives the fine 5 um element, and N means no gauge is fitted.
