SpxFlow Air Tool Hose Air / Water Separator
SPX Flow Air Tool Hose Air / Water Separators: Protecting Your Compressed Air System
When moisture infiltrates a compressed air line, the consequences reach far beyond simple inconvenience. Water and liquid contamination in compressed air can corrode steel tanks and piping, wash lubricating oils from pneumatic tools, and ultimately shorten the working life of every component downstream from the compressor. That is precisely the problem that SPX Flow has spent decades engineering solutions to solve — and their air tool hose air/water separators sit at the front line of that effort.
The SPX Flow – Hankison Heritage
SPX Flow's compressed air treatment expertise is rooted in its long-standing Hankison brand, which has built a global reputation in the compressed air treatment industry for delivering the latest technology and superior results. The Hankison line covers a wide spectrum of filtration grades — from bulk liquid moisture separators all the way to ultra-high-efficiency oil vapor removal — giving professionals the flexibility to tailor a system to their exact application, whether that's plant air, instrument air, or point-of-use tool protection.
For air tool hose air/water separators specifically, SPX Flow draws on Hankison's HF Series impaction-type separator technology. These units are engineered for efficient liquid and particulate removal, and are particularly well suited for installation in areas with large liquid loads — such as directly after an aftercooler, or as point-of-use protection on systems that lack aftercoolers or dryers altogether. This makes them an ideal choice for air tool hose applications where moisture accumulation is greatest.
Why an Air/Water Separator Matters at the Hose Level
Even in systems equipped with upstream dryers, residual moisture can condense as compressed air travels through cooler hoses and reaches air-powered tools. A separator installed at or near the tool connection intercepts that liquid water before it can enter the tool's internals — preventing rust, washing out grease, and maintaining consistent pneumatic performance. SPX Flow's Hankison-backed separators use an impaction-type separation mechanism that forces air through a path designed to knock liquid droplets and particulates out of the air stream, collecting them for drainage rather than letting them pass through to the tool.
Trusted Engineering Behind Every Unit
SPX Flow brings broad industrial engineering depth to this product category. Their filtration portfolio — spanning the Hankison, Deltech, and Dollinger brands — is built around the principle that removing water, oil, and dirt from compressed air increases output and protects equipment. Filter elements within the SPX Flow ecosystem are available in multiple grades, including Grade 11 moisture separator configurations designed expressly for liquid and particulate removal in demanding conditions. The result is a separator that professionals can rely on to deliver consistent air quality and extend the life of connected air tools and hoses.
Whether you are outfitting a single-bay garage or a multi-station workshop, an SPX Flow air/water separator provides the kind of upstream protection that keeps air tool hose systems running cleanly and efficiently.
