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 to15,000 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.
The PT-EZ770 Series projectors feature a lamp replacement cycle of up to 4,500 hours.*
This helps to lower operating costs by providing longer usage between lamp replacements.
* This is the maximum value when the lamp power is set to Eco2. Increases in the lamp on cycle or extended use with the lamp continuously turned on will shorten the lamp replacement cycle. When the lamp power is set to Eco1, the lamp replacement cycle is 4,000 hours and 3,000 hours when setting to Normal. The usage environment affects the lamp replacement cycle.
When the lamp power is set to Auto, the Intelligent Lamp Control system automatically adjusts the lamp output in accordance with the brightness of the projected image and reduces it by up to 58 %*. It also combines with color shift correction, which corrects the shift in the color balance that occurs when the lamp output drops. As a result, power consumption is effectively reduced while excellent color reproduction is maintained.
* With the lamp power set to Auto.
A number of functions are provided to reduce power consumption. They adjust the brightness according to ambient light conditions, and reduce the lamp power when there is no signal input. You can easily set the Eco Management functions according to operating conditions by using the ECO button on the remote control.

For easy maintenance, you can replace the filter from the side and the lamp from the top of the projector.
The filter and lamp are easily replaced even after the projector is installed on the ceiling.
The quiet design keeps noise levels down to 29 dB,* so the sound of the cooling fan is hardly noticeable. This helps the audience to keep their attention on the speech when someone is giving a presentation or on the screen images during quiet scenes.
* With the lamp power set to Eco2. 31 dB with lamp power set to Eco1. 37 dB with lamp power set to Normal.
