Two gold mining companies each chose multiple Tri-flow systems for dry dust control on thermal treatment systems that exhaust to atmosphere.
The Tri-Flow units range in capacity from 2000 to 20,000 cfm; all use Tri-Plus MERV 15 filters, an alternative proven superior to bags and cartridges, which are typically MERV 10-13.
Filter change-out is simple and “tool-free,” and is accomplished from the clean air plenum side, from outside the collector. No entering of the dirty air plenum is required for servicing.
Tri-Flow filter elements have a multi-year service life, and are easy to maintain using an integral pulse-jet cleaning system.
For companies who mine and process gold, platinum and copper, Tri-Flow dust control systems have provided an economical alternative, with HEPA level performance and a service life 3-5 times that of conventional bag or cartridge-type filters.
