What is a Scavenger?
A scavenger port is where the contaminants that were removed from the intake air by the equipment’s OEM pre-cleaner go to be disposed of.
How is the dust disposed?
The dust is either removed by a venturi in the exhaust system or by a blower.
1. The exhaust scavenger uses its velocity past a venturi to suck the contaminants from the OEM pre-cleaner where they will end up being blown back to the atmosphere with the exhaust.
– OR –
2. A blower driven by the engine will use its suction to pull the contaminants from the OEM pre-cleaner and blow them back to the atmosphere
Why is it important to account for a scavenger when sizing a Paragon™ for an engine?
A scavenging system on the intake will add additional airflow over and above what the engine requires. If unaccounted it may lead to selecting an undersized Paragon™ pre-cleaner potentially resulting in earlier filter light activations and a loss of the fuel savings benefit of adding a Paragon™ to the equipment.
Examples of Exhaust Scavengers
If you can identify a system like the ones in the examples below on your machine, you have a scavenger port.
