Does anyone know how much backpressure your typical 12v bilge
blower can tolerate?
They are marketed off the shelf in 3" - 4" dia and 150 to
250 cfm flows but do not list psig operating range as it is usually not a
factor to consider.
However, I would like to consider using one as a
lp ballast blow system similar to the WWII fleet boats lp blower system.
Could these be stepped down to a smaller dia and still do the job, or
routed at full dia?
Thanks
Joe
