A roof exhaust vent serves as a roof ventilator installed over the
roof surface. The unit is usually mounted to a roof base, and
both parts of the assembly are mated with FLS steel flanges
which make the joint and the whole assembly very sturdy and
stiff to resist strong gusts of wind. Other available versions
of roof exhaust vents include male and female connection
sizes for direct connection with spiral ducts and fittings or
matching roof bases. The roof exhaust vent can be made from
aluminium sheet or stainless steel sheet, whenever special
performance or material is required.
