FILTERS

Hosokawa Solids Solutions offers cutting-edge filters for bulk solids processing systems. Filters are the final component of a pneumatic conveying system, where the product is separated from the conveying air. To ensure efficient and high-performance conveying, Hosokawa uses special filter media that generate a low pressure loss despite a high filter surface load.

Hosokawa's RCF series with automatic cleaning is used as a primary filter stage after pneumatic conveying, as well as a breather filter during dosing/filling or as a silo filter. The FPO series acts as a kind of police filter to protect downstream equipment, such as vacuum generators, in the event of damage to the main filter. They also prevent the creation of an ATEX zone at the air outlet.

Product range

Explore our range of filters and discover how they can improve your powder handling process:

  • Solids filter RCF-Basic

    Compact, stand-alone filter unit with cartridges for dust separation after pneumatic conveying, as a vent filter during dosing/filling, or as a silo filter. It features automatic cleaning, optional differential pressure monitoring, and direct mounting on containers or silos.

    Key benefits include:

    • Easy dismantling and cleaning with quick release rings;
    • Minimal contamination during control and cartridge exchange;
    • Conical filter elements for uniform cleaning and extended filter life;
    • Energy-efficient cleaning with a multijet nozzle;
    • Low-pressure loss (<10 mbar) and high load capacity (up to 6 Nm³/m² per minute).
  • Solids filter RCF-Clean

    Compact, stand-alone filter unit with cartridges for dust separation after pneumatic conveying, as a vent filter during dosing/filling, or as a silo filter. It features automatic cleaning, optional differential pressure monitoring, and direct mounting on containers or silos.

    Key benefits include:

    • Easy dismantling and cleaning with quick release rings;
    • Minimal contamination during control and cartridge exchange;
    • Conical filter elements for uniform cleaning and extended filter life;
    • Energy-efficient cleaning with a multijet nozzle;
    • Low-pressure loss (<10 mbar) and high load capacity (up to 6 Nm³/m² per minute).
  • Solids filter RCF-Hygienic

    Specifically designed for applications requiring strict hygiene standards, such as food, pharmaceuticals, and cosmetics. It meets all current regulations for food processing (EC/FDA/DIN EN 1672-2) and features the same benefits as the RCF-Clean, with additional focus on:

    • Hygienic-Dry Design according to EHEDG guidelines;
    • Minimal contamination during control and cartridge exchange.
  • Solids police filter FPO-Clean

    Stand-alone, passive filter unit with cartridge, designed to protect the clean gas side of a filter against leakage/defects. With differential pressure monitoring and no filter element cleaning. Suitable for use in ATEX zones 20-21-22, although it is not classified as an ATEX device. Any additional electrical components must be approved for the selected ATEX zone.

    Key benefits include:

    • Easy dismantling and cleaning;
    • Protection of blowers/fans from primary filter system damage;
    • Reduction of ATEX danger zones at the clean gas outlet.
