Epson has created two dust-proof projectors designed to make presenting in dusty or sandy locations trouble-free.

The EB-D6155W and EB-D6250 have an exhaust shutter system that automatically closes when the projectors are not in use, preventing dust, dirt or sand from getting in and causing damage. Their optical engines are also encased in glass to offer further protection against the elements.

Designed to withstand extreme conditions, Epson claims these robust projectors are ideal for organisations based in locations where dust and sand are a constant issue.

The company says the projectors are also suited to public displays in large enclosed spaces such as factories, clubs, arenas, schools, universities and churches.

The projectors' electrostatic filter can last up to 10,000 hours, while the E-TORL lamp gives up to 4,000 hours of light before needing to be replaced.

Both models also feature a high-performance 5W integrated speaker and come with an HDMI input for top-quality digital images and sound through a single cable.

The EB-D6155W delivers up to 3,500 lumens brightness and WXGA (1280 x 800) resolution, enhanced by 3LCD technology, for quality, widescreen images. The EB-D6250 has up to 4,000 lumens with XGA (1024 x 768) resolution.
