Backflow Preventers
Backflow preventers: The backflow preventers (or one-way valves) are found in the base of the
system positioned between the blower and airlock. The backflow preventers will keep insulation from
flowing backwards through the airlock and into the blower which may happen when the pressure of
product in the hose is more than that of the pressure in the line between the blower and airlock -
examples include (i) hose moving straight up from machine to a second or third story, or (ii) during
some dense pack operation. The back blow preventer prolongs the blower motor's life.
