24", 32", 36" Fans, Rated Power 0.55kW/0.75kW, 380V, 50Hz, 3-phase
Function:
To exhaust stale air accumulated in the upper section of livestock and poultry houses. It provides a comfortable indoor environment while saving energy, effectively helps prevent cross-contamination among animals, and reduces the incidence of disease. It performs particularly well during minimum ventilation in winter. Installed on the roof, it only requires a square opening, making construction and sealing much simpler compared to a round opening.
Component Features
Extension Duct, Exhaust Duct, and Rain Cap:
Material: Core is XPS (with a low thermal conductivity of ≤0.032 W/m·K and a density of 28 kg/m³). Inner and outer walls are made of 0.8mm FRP.
Benefits: Provides thermal insulation, effectively prevents condensation. These components can be nested for shipping, significantly saving transportation costs. Length can be customized according to barn height. Modular design allows for simple installation.
