Frequently Asked Questions
Q: What does the SAW400-N04BG do?
A: It combines particulate filtration and pressure regulation in one compact piggyback unit to help deliver cleaner, regulated compressed air downstream.
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 manual drain filter regulator?
A: A manual drain is a good option when the unit is easy to access and part of a routine maintenance schedule for draining collected condensate.
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.
Q: What accessories are included?
A: This model includes a 0–150 PSI external gauge and mounting bracket.
