Model Selection
IDFA E Selection Example
Read the correction factor.
Obtain the correction factor A to D suitable for your operating
condition using the table below.
The corrected air flow capacity, which considers the user’s operating conditions, is required for selecting
the air dryer. Please select using the following procedures.
1
Calculate the corrected air flow capacity.
Obtain the corrected air flow capacity from the following formula.
Corrected air flow capacity = Air consumption
앦
(Correction
factor A x B x C)
2
Select the model.
Select the model which air flow capacity exceeds the
corrected air flow capacity using the specification table. (For
air flow capacity, refer to the data D below.)
According to the corrected air flow capacity of 48.9 m
3
/h, the
IDFA8E
will
be selected when the required output air pressure dew point is 3
°
C. The
IDFA6E
will be selected when the required pressure dew point is 10
°
C.
