Precautions for using anti-dust enclosure
-When using the anti-dust display(enclosure), please remove the dust with filter.
Precautions for using the filter
(1)it is possible to prolong the filter life by using two filter and
exchanging the fine screen pre-filter.
(2)it may raise the internal temperature for a monitor when using the filter, because of raising
the air resistance.
Please reduce the air resistance by increasing the area of filter, etc.
(3)when circulating air with a fan, it needs attention how to make the enclosure whether
exhaling or inhaling air from the fan.
Intake air fan:
The pressure in the enclosure is higher than out of enclosure. Therefore, dust does not break in
the housing. It is limited the size of intake vent. And it is difficult to suck in much air(when using
in dusty area).
Exhaust air fan:
The pressure in the housing is lower than out of enclosure. Therefore, dust breaks in the
housing. It has much size of intake vent. And it is easy to control the temperature(when using
in less dusty area and severe temperature requirements).
※to keep the performance, please clean the filter regularly
