Safe Vent Screen UsageThe PVS-IS3 is an American made three inch PVC vent screen designed to protect horizontally vented high efficiency appliances from intrusion by rodents, bees, wasps and other insects. The PVS-IS3 offers maximum protection while maintaining a 70% airflow rate, which exceeds that of the many cheap plastic rodent vent screens imported into the United States.

Bees, wasps and other insects can lead to big repair bills if they nest inside the vent of a high efficiency furnace, hot water heater or boiler. In addition to calling a repairman for the appliance, often a pest control specialist needs to be called in to deal with potentially dangerous nesting situations. The PVS-IS3 is designed to prevent these problems from happening, while still providing maximum airflow for the appliance when temperatures are above freezing. Those residing in regions where temperatures drop below freezing, and throughout winter, should use the PVS-RS3 when temperatures are below freezing as part of a comprehensive all-season vent protection program.

The PVS-IS3 is constructed with a lightweight 6061-T6 aluminum shell that houses a tough 18×18 316 stainless steel screen. The screen is held in place with one 304 stainless steel internal wire clip (included) so that the entire screen remains hidden inside of a standard 3” hub/elbow. The entire screen resists corrosion and is designed to outlive modern day appliances. As with all of our PVC vent screens, the PVS-IS3 can be easily installed in less than a minute.

In addition to bees and wasps, the PVS-IS3 also guards against:

  • Beetles
  • Birds
  • Butterflies
  • Chipmunks
  • Cicadas
  • Crickets
  • Grasshoppers
  • Mice
  • Moles
  • Mosquitoes
  • Moths
  • Spiders
  • Squirrels

As with all of PVS series vent protection products, the PVS-IS3 is constructed from materials sourced within the United States and is manufactured in America.
