Filter housings have been designed with energy efficiency in mind and combine smooth, burr-free inner surfaces with in-line ports sized optimally to match required system flow rates. Incoming air passes through a stainless steel head which transfers the compressed air flow through the filter elements. Hi-line says this results in an exceptionally low differential pressure.

The use of in-line rather than offset ports ensures a compact and simplified installation, while also providing easy access to the filter element chamber for service/replacements.
