Filters & Filter Housings

Bulk Technik can provide a number of different air filtration systems for de-dusting the air when conveying product pneumatically into silos. The most simple filter is the sock type filter that is commonly used in the cement industry, while the more advanced filters operate with air jets that pulse the filter bags are regular intervals.

The sock type silo filter consists of a mild steel filter housing that allows the filtered air to escape, but prevents any ingress of rain into the silo. A conical filter bag is fitted to a mild steel cage, which in turn is bolted to the housing. For maintenance purposes, the hinged housing hood can be rotated and the bag insert removed. This is a cheap and reasonably effective method of filtering the air, however, the filter bag must be cleaned at regular intervals.
