Informational Alert: IN5300 & IN5500 Series – Details for Hush Box/Quiet Enclosure Designers
Subject: Projector airflow specifications and recommendations for design
Some PROAV/Home Theatre installations may require specialized quiet enclosure/hush box enclosure designs for the IN5300/IN5500 series or the SP8602 projector models, below are some guidelines that will assist designers to ensure proper operation and thermal control.
The IN5300 series & SP8602 use a single exhaust fan. It's a 105mm high flow fan for a max flow of 90 CFM.
The IN550x (Single – lamp models) use one 120mm high flow fan for a max flow of 100 CFM.
The IN553x (Dual-Lamp Models) uses two 120mm high flow fans for a combined max flow of 200 CFM.
Ensure in all cases to design the hush box so that the external box fans that are used do not interrupt the exhaust airflow from the projector (causing negative projector back pressure) as well as ensuring thermally controlled airflow within the enclosure thus ensuring proper circulation/thermal control within the projector/housing.
In some cases the use of filtration is recommended on the intact air ducting system on the hush box to eliminate smoke, nicotine, and other harsh environmental factors again depending on the usage model design parameters.
Projector Exhaust and Intake Flow:
- Exhaust air exits the projector out the rear panel
- Intake air is through left side front and right side front in desktop (upright) mode
- Exhaust air exits the projector out the rear panel as well as right side rear near lamp in desktop (upright) mode (looking at the lens)
- Intake air is through left side front in desktop (upright) mode and left side of the bottom (2 areas) (looking at the lens)
Good baseline recommendation for the fans used on the enclosure is to utilize the same type as is used inside the projector (120mm high flow fan for IN5500 series & 105 mm high flow fan for IN5300 series/SP8602)
