First ejection cycle:
| 1 |
Debris-laden air enters the primary ejection chamber. |
| 2 |
Debris particles are accelerated outward by centrifugal forces. The particles then ride along the outer wall of the ejection chamber. |
| 3 |
When the debris reaches the ejection port, it is expelled back into the atmosphere. |
Second ejection cycle:
| 4 |
Air is accelerated as it passes through louvers, further enhancing the debris-separating forces. |
| 5 |
Finer debris is then stratified in the secondary ejection chamber. |
| 6 |
When the fine debris reaches the ejection port, it is expelled back into the atmosphere. |
Filtration:
| 7 |
Clean air continues into the air filter housing and passes through the filter. |
| 8 |
Fresh air continues into the evaporator coil box for heating and cooling. |
Benefits:
Extends maintenance intervals which lowers cost per operating hour.
Powered precleaner adds no resistance to airflow - air is pushed by precleaner rather than pulled by fan motor.
Filter life extension reduces costs - some gain as much as 10-20x filter life. Red Dot recommends changing filter at 1000 hours even if resistance indicator has not alerted.
Evaporator coils receive only precleaned, filtered air, avoiding main reason for repairs
