PneumaticPlus SAW400-N04BDG Air Filter Regulator Combo | 1/2" NPT, 106 SCFM, 10 Micron | Poly Bowl, Auto Drain
The PneumaticPlus SAW400-N04BDG is a piggyback compressed air filter regulator designed to deliver clean, regulated compressed air at the point of use for pneumatic tools, automation equipment, and industrial compressed air systems.
This 1/2" NPT air filter regulator combo provides 10 micron particulate filtration, a 0–150 PSI standard operating range, and an auto drain polycarbonate bowl for applications where automatic condensate removal is preferred. A 0–150 PSI gauge and bracket are included.
Common Applications & Use Cases
The SAW400-N04BDG is commonly used in 1/2" NPT compressed air lines where filtration, pressure regulation, and automatic moisture draining are needed in one compact piggyback unit.
- Higher-duty compressed air systems: Helps reduce the need for manual bowl draining during routine operation.
- Automation equipment: Helps protect valves, cylinders, and actuators from particulate contamination.
- Machine panels and OEM equipment: Compact design helps save space and simplify installation.
- General industrial air lines: Supports stable downstream pressure while assisting with moisture management.

Frequently Asked Questions
Q: What does the SAW400-N04BDG do?
A: It combines particulate filtration and pressure regulation in one compact piggyback unit and adds automatic condensate draining for easier routine operation.
Q: When should I choose an auto drain filter regulator?
A: An auto drain model is a good choice when frequent moisture removal is expected or when manual draining is less convenient.
Q: What does 106 SCFM mean?
A: It is the rated airflow capacity used for sizing the filter regulator so it better matches the air demand of your compressed air system.
Q: When should I choose a metal bowl instead of a poly bowl?
A: Choose a metal bowl for harsher environments, for applications above 150 PSI, or where chemicals, solvents, or oils may degrade polycarbonate over time.
