AirTAC GFR400-15 Filter Regulator (GFR40015MF1WK)
The AirTAC AirTAC GFR400-15 Filter Regulator (GFR40015MF1WK) 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 (GFR40015MF1WK)
The AirTAC GFR40015MF1WK is a filter regulator that cleans compressed air to 5 um and regulates downstream pressure in a single body, with a built-in check (reverse) valve that permits back-flow from the outlet side when supply pressure is removed. This 400-size configuration has a PT 1/2 in port, a polycarbonate bowl with manual drain, the fine W-grade element, and an embedded square gauge scaled in MPa. Manual drainage gives a regulator set range of 0.05-0.9 MPa (7-130 psi); maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the G-series, which runs from size 200 to 600 and offers automatic or differential-pressure drains, the 40 um standard element, psi or bar gauge scales, G (BSPP) or NPT threads, and bracket options. Because rated flow is published only as curves, we will confirm the datasheet figures for your sizing question 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.

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 (GFR40015MF1WK) Is Used
Robotic welding cell gripper air
Regulates and finely filters air to robot grippers on a weld line, with the check valve preserving gripper pressure if the cell supply is interrupted.
Test bench clamping circuits
Provides clean, settable air to hydraulic-boost clamps on a test bench, letting engineers read MPa directly and bleed the manual bowl between runs.
Food packaging machine protection
Guards seal-bar and forming pneumatics on a packaging machine with 5 um air while the check valve cushions the circuit against supply dips.
Is the AirTAC GFR400-15 Filter Regulator (GFR40015MF1WK) the Right Unit?
Choose this code when you need three things at once: the 400-size PT 1/2 in port for heavier air demand, the 5 um element (W) for finer filtration, and the K check valve to hold downstream conditions during supply dropouts. Drainage is manual here, with the 0.05-0.9 MPa (7-130 psi) set range; unattended installs should step to automatic or differential-pressure drain codes, which set 0.15-0.9 MPa (20-130 psi). Gauge scale can be ordered in psi or bar, threads as PT (standard) or G (BSPP)/NPT to order, and a bracket is included by default. Flow appears in the catalogue as curves, not a single rating, so ask us to check the datasheet against your demand 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 (GFR40015MF1WK) FAQ
AirTAC publishes G-series flow as curves rather than a single rated figure, so we do not quote a number here. Give us your flow demand and operating pressure and we will confirm the datasheet figures for this 400-size, PT 1/2 in unit on request.
W selects the fine 5 um filter element over the standard 40 um grade, and K means a check (reverse) valve is fitted so downstream air can flow back when the supply shuts off. The M indicates a manual bowl drain, which sets the regulator range at 0.05-0.9 MPa (7-130 psi).
