Control Box that has been convex shape
is now united with main unit (DIP Switch is
located on the internal substrate.)

One-touch operating and easy-to-install
long-life filter (optional)

In addition to the slim height of 270 mm which is our sales point, further com­pactification is attained by reducing 65 mm from the width with the flanking

Structural improvement is attained by making the bottom panel two pieces, front and
rear, and the internal fan casing is also made dismountable in two pieces namely,
upper and lower ones.
The motor and fan maintenance and dismounting can be made easily by removing
the rear panel and lower part of the casing with the main chassis installed.
