High static pressure duct indoor units with DC fan motor 7. Fan Performance Heating and cooling capacity are tested under the standard allowable static pressure; the 71 test static pressure is 25Pa, 80/90/112 test static pressure is 37Pa, 140/160 test static pressure is 50Pa, the 200/250/280 test pressure is 62Pa.
Page 138 High static pressure duct indoor units with DC fan motor  If the external static pressure is too high, caused by extensive ducting for example, the air flow volume at each outlet may be reduced to insufficient levels.  So there’s a limit air flow volume for each speed, which is the min. airflow of this duct unit. At this flow volume, the fan achieve the max.

Page 167: Fan Performance
Fresh air processing duct indoor units with DC fan motor 9. Fan Performance Heating and cooling capacities are tested under the standard allowable static pressure; the 125/140 test static pressure is 50Pa, the 200/250/280 test pressure is 62Pa.  If the external static pressure is too high, caused by extensive ducting for example, the air flow volume at each outlet may be reduced to insufficient levels.
