The cabinet is designed with a straight airflow path, from intake to exhaust.
The shielding of the lens section, where dust is likely to enter, has been further improved to keep dust out. And the sealing performance of the air filter unit and air intake duct has been increased to prevent the entry of dust from the filter periphery, resulting in a highly dust-resistant structure.
The Eco Filter unit, which efficiently captures dust in the intake airflow path, requires no replacement for up to12,000 hours.* This large, pleated Micro Cut Filter (electrostatic filter) uses an ion effect to trap minute dust particles, further raising the overall dust-trapping capability.
These features minimize the entry of dust into the optical block and maintain brightness over a long period of time, while reducing the hassle of maintenance. Also, in addition to achieving a long replacement cycle, the Eco Filter can be washed with water** and reused as an environmental consideration.
* The usage environment affects the duration of the filter.
** When washing with water, please follow the procedures listed in the operating instructions. Also, we recommend replacing the filter with a new one after it has been washed and reused twice. If the filter is not sufficiently clean after washing, replace it with a new one.
