Dust is everywhere

All electronic products are exposed to airborne dust throughout their lifetime.

This is not generally a problem for most consumer products but for professional applications, such as museums or attractions, where projectors need to operate around the clock, the build-up of dust particles can potentially compromise the quality of the image projected, affect the overall performance of a projector and shorten its lifetime.

 

Dust-sealed filter-free design

Optoma’s ProScene laser projectors are precision engineered with a unique optical dust-sealed, filter-free design that prevents dust and dirt affecting the system. The projectors need very little maintenance as there are no filters to remove and clean, therefore minimising downtime for the venue.  In addition, Optoma’s ProScene DuraCore laser line-up all come with an IPXX independent dust resistant certification.

 

What is an IPXX certification

An IP rating stands for ingress protection and basically states how well the equipment is protected from dust or liquids.  The IP code, published by the International Electrotechnical Commission, rates the degree of protection given by the electrical equipment casings against dust or water. The standard provides consumers with more detailed information than vague marketing terms such as ‘dustproof or waterproof’. Independent Ingress Protection tests are conducted in accordance with IEC 60529.

 Optoma ProScene ZU850 laser projector

ZU850 gets top marks for dust resistance

We recently sent our 8,200-lumen ZU850 laser phosphor ProScene projector to an independent IP test lab. The researchers placed the projector in a dust chamber and exposed the unit to airborne circulating dust for 8 hours at 25 °C ± 10 °C.

On completion of the test the black unit was caked white with dust but was found to be dust tight with no dust passing through the airtight optical engine and functional operation unaffected.

The ZU850 was awarded the highest classification of IP6X – which offers a completely dust free protection for the device.
