BHV Spiral duct is the ideal duct system for all
heating, ventilating, air conditioning, industrial exhaust, and make
up air systems.
Round spiral duct can be manufactured in lighter
gauges than comparably sized rectangular ductwork, and will have equal or
greater strength.
Flat oval duct will fit easily in
confined spaces. In addition, spiral duct
installations are more efficient. Due to generally lower loss co-efficients
of the round configuration versus square or rectangular duct and
fittings of equal area. Also, the longer available lengths provide
more efficiency due to the elimination of many of the field
connections and resulting leakage found in conventional rectangular
duct installations.
BHV round and flat oval spiral duct is available in
plain and double beaded profile. Double beaded profile is standard
construction for our round underground PVS
duct.
