Thermoplastic Duct Reducers
PVC coupling type reducers are designed for connecting thermoplastic duct of
different diameters. Compare your blower inlet size with your duct size to see if
one is necessary.

Zero Pressure Weathercaps
The zero pressure weathercap is made of strong, corrosion-resistant PVC. The cap
adds little static pressure to the exhaust system and allows for vertical discharge of
the effluent air for dispersion away from the building.
