Strainer Specifications

Strainer Assemblies There are five different in-line strainer product lines designed to fit the various needs of Ron-Vik's customers. Below is a brief description of each product line and general dimensions.


Low Profile and Mini Series

Low profile in-line strainers are used in applications where there is a minimum amount of space and which allow for a small filter area. If more filter area is necessary, the low profile tops can be matched with a longer bowl, these assemblies are referred to as the Mini Series. Common applications for these strainers include, home water treatment systems, floor cleaning equipment and medical supply. The chart below shows common dimensions for standard assemblies, however, tops are also available with female Whitworth threads in polypropylene and nylon.

Intermediate Series

Intermediate SeriesThese assemblies are the most commonly used due to their compact size but large filter area.
