Campbell Hausfeld 516803 Mini Filter Regulator
The Campbell Hausfeld 516803 is a mini filter regulator with a 1/4 inch NPT connection designed to clean and control compressed air. It uses a sintered bronze filter element to remove moisture and particulates from the supply line. This unit suits hobbyists and light-duty workshops needing point-of-use air preparation. It is not for high-volume industrial systems requiring larger flow capacity.
Replaces basic inline filters without pressure
Adding this regulator upgrades a simple filtration setup by letting you set precise downstream pressure for each tool. The jump is worth it when switching between spray guns, nailers or tyre inflators that need different operating pressures. It does not replace a full-sized filter-regulator-lubricator assembly for heavy continuous use. Buyers needing integrated lubrication or higher flow rates should look elsewhere.
Threads directly into 1/4 NPT ports
Installation requires only threading the unit into a matching 1/4 NPT port using a wrench on the provided flats. The compact body fits tight spaces but offers less leverage than larger regulators. Over-tightening can damage the bronze filter housing or strip the threads. Ensure the flow arrow points toward the tool and drain the bowl regularly to avoid water carry-over.

Questions about this item
What thread size does the 1/4 NPT port on this mini filter regulator require for connection?
It uses a 1/4 inch NPT thread for inline installation on an air line.
How is the unit oriented during installation so the filter bowl drains correctly?
Mount the body vertically with the bowl pointing down so condensate collects and can be drained.
When should the sintered bronze filter element be cleaned or replaced?
Service the element when pressure drop across the regulator increases or airflow to the tool noticeably falls.
