Low static pressure mode function

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

Large bottom panel: 1 unit
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.
