Model W1666/W1685 (For Machines Mfd. Since 2/15)
SETUP
If two machines will connect to the same branch line and
both will operate at the same time, then add the required
CFM for each machine together and find the closest total
CFM in the table in Figure.33.to determine the correct
branch size.
If both machines will never run at the same time,
reference the machine with the biggest dust port in the
table below and add blast gates after the Y-branch to
open/close the line to each machine.
Planning.Drop.Downs
Plan the drop downs for each machine, using blast gates
wherever possible to control airflow (see Figure.34).
