The use of a DC motor
In the past, the only models featuring a DC motor were the P200 (8 HP) and P250 (10 HP). Now, the P140 (6 HP) and smaller models
feature a DC motor that consumes less power compared to AC motors. In the P80 models, power consumption is reduced by 59%*.

Reduced weight
By downsizing the motor, the unit weight has been reduced,
offering easier installation.

Four levels of external static pressure settings
While the conventional models only had three levels of external static pressure, the latest models offer four levels of external static
pressure. The additional external static pressure capacity provides flexibility for duct extension, branching and air outlet configuration.

The factory setting of external static pressure is shown without brackets (< >).
Refer to "Fan characteristics curves" according to the external static pressure, in the DATA BOOK for
the usable range of airflow rate.
Three fan speeds (Low/Mid/High) to choose from
The conventional models had two levels of fan speed, but the latest models offer three levels (Low/Mid/High). Combined with a wider
selection of external static pressure levels, the latest models offer optimal operation settings to suit the air-conditioning load of the
installation space.

DC motor
Drain pumps (sold separately)
with a DC motor are now also available.
The use of a high-efficiency DC motor for the drain pump motor in
the latest models reduces power consumption by 90%, in
comparison to conventional models. The pump head height of
550 mm provides for greater piping design flexibility.
