Hyvent Silo Filter Venting Unit

Hycontrol's Hyvent dust collector and filter unit is specifically designed to vent silos during the filling process without allowing valuable powdered product to escape. The product is filtered from the air during both the conveying period and the air surge at the end of the cycle. The filter is self-maintaining, returning powder back into the silo via an automatic reverse-jet pulse cleaning system which utilises compressed air.

This filter unit features the latest technology in conical-shaped filter design. This patented cone shape provides outstanding cleaning efficiency while enabling maximum airflow through the unit, and has the added benefit of increased life for the cartridges. They offer many advantages over traditional cylindrical cartridge or bag filters due to their compact design, higher filtration efficiency and superior pre-separation of dusts. The tapered shape increases separation resulting in reduced up-stream air velocities, increased pre-separation and lower dust re-entrainment. The filter unit has a rugged weatherproof construction and is built for safe and simple maintenance.

Hyvent has been designed to the latest guidance from the Mineral Products Association (MPA) and to meet HSE guidelines on the prevention of over–pressurisation of storage silos during deliveries. It complies fully with environmental emission standards and is capable of filtering all types of powders. Whilst it is available to purchase separately, Hyvent also forms an integral component of Hycontrol’s advanced SHIELD silo protection system, providing the ultimate defence against the dangers of overfilling and over-pressurisation in powder silos.
