The 4 inch Aura Solar PVC Vent Cap is for ventilating vapors and particles from a PVC pipe. This Vent Cap is for both commercial and residential applications. The model ASF-4-PVC fits over a 4 inch PVC pipe.
This Vent Cap uses both solar and wind power to ventilate PVC pipes. The solar panel only works in bright direct sunlight. However, the fan will still work passively by using the Venturi Effect. When the wind blows against the outer louvers this creates an upward draft which allows air to freely flow in and out of the vent.
When the motor is off the attic fan will still ventilate passively. In other words, even the smallest breeze can create exhaust ventilation to draw air out of the fan. This movement of air is proportional to the wind speed and is measured in cubic feet per minute (CFM).
If ventilating radon exhaust systems, the PVC Vent Cap's superior exhausting optimizes the CFM for the in-line fans. As a result, this eliminates back pressure to the in-line fan traditionally caused by using T-Fittings or two 90 degree elbow fittings. In addition, this protects the fan from moisture damage caused by rain, snow or ice entry.
When ventilating environmental remediation systems, the Aura Solar PVC Vent Cap can be used to cap the PVC pipes used to release vapors in numerous places. For instance, some places may include landfills, gas stations, contaminated soil sites, chemical containment bunkers and groundwater sites.
