Conical Filters & Cone Filters


Conical filters are a rugged, cone-shaped, industrial grade air intake filter. Similar to our metal end cap filter line; Sidco’s conical filters are manufactured from heavy duty materials and can withstand high-temperature environments when made with special potting compounds. The open/closed metal end cap style typically has a gasket on the open end and a bolt hole in the closed end cap. Conical filters are used in air intake housings and silencers for large centrifugal blowers and compressors. Sidco’s replacement conical filters are designed to meet OEM specifications and provide a significant saving in cost.

Conical filters are also referred to as cone filters.
