The Rugged Radios dual-stage pre-filter kit is a combined intake solution for MAC air helmet pumpers that uses two filtration stages ahead of the main filter. Supplied as a kit for MAC-compatible pump units, it captures larger particles first and finer debris second, extending the life of the primary filter and simplifying maintenance for helmet air systems.
