AirTAC GFR400-15 Filter Regulator (GFR40015AF2)
The AirTAC AirTAC GFR400-15 Filter Regulator (GFR40015AF2) 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 automatic 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 GFR400-15 Filter Regulator (GFR40015AF2)
The GFR400-15AF2 is an AirTAC G-series filter regulator: one body that removes water and particulate from compressed air and reduces pressure to the level your equipment needs. This configuration is the size 400 unit with a 1/2 in PT port, an automatic drain that ejects collected condensate without operator attention, the standard 40 um filter element, and an embedded square gauge scaled in psi so you can set and monitor downstream pressure at a glance.
This is a genuine AirTAC part. The G-series filter regulator family runs from size 200 to 600, with larger sizes carrying larger ports and more flow capacity, and options including 5 um filtration, manual drain, G (BSPP) or NPT threads, a check valve, and alternate gauge scales. Published flow data appears as curves rather than a single rating, so we confirm flow and datasheet figures for your application on request.

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 (GFR40015AF2) Is Used
Packaging conveyor air supply
Feeding clean, regulated air to cylinders and actuators on a packaging conveyor line, with the automatic drain handling condensate during continuous shifts and the psi gauge letting line staff verify set pressure.
CNC machine tool air preparation
Conditioning shop-air ahead of a CNC machining centre's pneumatic tool-change and clamping circuits, where stable downstream pressure and 40 um particulate removal protect valves and cylinders.
Food-plant palletiser controls
Supplying regulated air to the gripper and clamp circuits of a palletising cell, where the automatic drain keeps the bowl clear without daily operator rounds and the square gauge shows the setting in psi.
Is the AirTAC GFR400-15 Filter Regulator (GFR40015AF2) the Right Unit?
Step up from GFR200/300 to this GFR400 size, with its 1/2 in port, when your line moves more compressed air than the smaller frames are sized for; the published flow curves, not a single rating, decide the step, so ask us to check sizing against your demand before ordering. The automatic drain here suits unattended or hard-to-reach installations; choose manual drain if you prefer a deliberate, supervised dump, and note that the regulator setting range differs by drain type: 0.15-0.9 MPa (20-130 psi) with automatic drain. The 40 um element is the standard grade; pick the 5 um W option if downstream components need finer filtration. Thread is PT as standard, with G (BSPP) and NPT available as catalogue options, and a bracket can be ordered for mounting.
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 0.15 - 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 GFR400-15 Filter Regulator (GFR40015AF2) FAQ
AirTAC publishes flow for this series as performance curves, not as a single rated figure, so we do not quote one number. Send us your line pressure, port size and air demand, and we will confirm the flow and full datasheet figures for the GFR400-15AF2 on request.
Automatic drain means collected condensate is ejected from the bowl without manual attention - useful on machines that run unattended. With an automatic-drain filter regulator the pressure adjustment range is 0.15-0.9 MPa (20-130 psi); the manual-drain versions of this family open a wider 0.05-0.9 MPa (7-130 psi) range.
