4. Determine the projector's exhaust CFM value.
Use an airflow meter to measure the ft/min at the rigid end of the open exhaust duct
connecting to the projector. Take the measurement at the end of the duct without the projector
connected. Use this formula to determine the CFM value for the projector: CFM = 0.35 ×
Measured ft/min.
Notice. If not avoided, the following could result in property damage.
•
Do not attempt to operate the product with inadequate airflow which can result in
dangerous overheating.
Lamp type
Minimum airflow required (CFM)
2.0 kW
• 450 CFM at less than or equal to 25°C (77°F) ambient and less
than 3,000 feet (915 m)
• 600 CFM above 25°C (77°F) ambient or above 3,000 feet (915
m)
3.0 kW
• 450 CFM at less than or equal to 25°C (77°F) ambient and less
than 3,000 feet (915 m)
• 600 CFM above 25°C (77°F) ambient or above 3,000 feet (915
m)
5. Add an extractor or a booster if insufficient airflow exists.
Do not mount the extractor on the projector as this may introduce some vibration into the
image.
