Air Movement
One poultry consultant sees an
improvement in fan efficiency
and a tiend towaid laigei fans,
perhaps as large as 60 inches
He also notes that variable speed
motors for fans are no longer
needed with the ia,ge number of
birds in most houses
Air volume would be con
trolled by simply cutting off or
taming on fans because the total
change m cubic feet per minute
is spread with many birds
The problems, say the ven
tilation experts, have been to
develop controls that aie sensi
tive enough to do the job, yet
capable of withstanding the
working conditions of a poultry
bouse.
