2.Normal Mode Air volume at 100Pa (fan speed:high)

When installed, normal middle static pressure mode, and low static pressure mode can be selected by switching over using DIP switch on the board in the control box. Therefore, these models can be operated under the wide range of conditions.

Slim & compact design

In the case of bottom suction type, as seen from lower rear part.

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 control box embedded inside the chassis.
