To Scavenge or Not Scavenge…
PSD air cleaners are designed to operate with or without aspiration, otherwise known as scavenging. Scavenging is accomplished by introducing a secondary airflow to the drop tube on the air cleaner (generally through the use of an ejector or ejector muffler). This flow pulls the separated contaminant from the precleaner and inserts it into the exhaust stream. The advantages to scavenging are: • Higher pre-cleaner efficiency (resulting in longer filter service life) • Completely self-servicing (no regular maintenance needed on pre-cleaner) • Drop tube can be located in variety of orientations (not just straight down as is necessary on non-scavenged systems) Aspirating an intake system through the use of a scavenging device adds more components (an ejector and some plumb- ing) to the overall system, but will enhance the separator efficiency of the pre- cleaner and consequently extend the filter service life. Conversely, the PSD air cleaner and precleaner will function adequately without scavenge, with the result being less filter service life than with the use of scavenging.
