The puraDYN Bypass Oil Filtration System continuously cleans the lubricating oil by removing 100% of solid contaminants, as well as removing liquid contaminants. PuraDYN systems are designed to work in conjunction with the full-flow filter, removing the smaller solid contaminants as well as water and fuel. This results in 100% reduction in new oil purchases and the cost of waste oil disposal, less downtime and increased engine life.
