Before Precleaner installation,both filters were changed every 150 hours and blown out every 60 hours (filter blow-outs are never recommended as they can damage air filters). Filters were changed when the restriction light came on. Cost* for parts and labor: $2660 per machine.

After Precleaner installation, both filters were changed at 610 hours, even though there was no restriction indicated by signal light. Cost* for parts and labor: $402.12 per machine.

Savings over 2000 hours of operation: $2,257.88*

*Costs:Filters $55.77 x 2 per change, Labor $30 per hour.
