When secured in the operating position with the included 304 stainless steel wire clips, there is no need to buy caulk or use fasteners that would damage the PVC. Our internal wire clips are easily installed in under a minute and can be removed just as effortlessly – without damaging the PVC pipes.

Our PVS-IS3 vent screens are unique in that they maintain a 70% rate of airflow. Unlike plastic rodent only vent protection products, which often restrict 40%+ airflow, each PVS-IS3 in this set will also guard against intrusion by insects in addition to keeping animals outside of homes. Many individuals choose to use these insect screens during spring, summer and fall then switch to the PVS-RS3 during winter when freezing temperatures and snow may cause vent icing concerns that could potentially result in an unwanted furnace lockout.

The PVS-IS3 is the most versatile PVC vent guard available and is used by professional plumbers, HVAC technicians and pest control specialists as its rated airflow offers optimum compatibility with horizontally vented condensing furnaces, power vent hot water heaters and boilers.
