Product Description

The GUARDAIR N635H is a HEPA cartridge filter designed for dry pickup applications using drum-top vacuum heads. It delivers 99.97 percent filtration efficiency, capturing fine particulate matter generated during industrial cleaning, surface prep, and facility maintenance tasks. The filter fits drum-top vacuum units with 30-gallon and 55-gallon tank capacities, making it a direct service part for shops, job sites, and facilities that run high-capacity industrial vacuums.
