Safe Vent Screen UsageOur three inch PVS-IRS3 PVC vent screen kit provides both value and all-season vent protection for one 3″ PVC pipe vent. Included in this package are one PVS-IS3 vent screen for dual insect and rodent protection and one PVS-RS3 vent screen for use during months when only rodent protection is needed. Also included are two 304 stainless steel internal wire clips, which are used to quickly install and secure our vent screens in place without damaging your 3″ PVC hub/elbow. The supplied stainless steel clips may be reused season after season and their use eliminates the need for caulk, screws or other types of fasteners to secure our vent screens in place.

Our PVS series vent screens all utilize a high quality 6061-T6 aluminum shell for its anti-corrosive properties. Our mesh and welded wire screens are made of 316 stainless steel, which is also highly resistant to corrosion, and are designed to years of trouble-free service. When secured in place with the included 304 stainless steel internal wire clips, our screens will protect you from costly repair bills resulting from insect and/or animal damage.

The PVS-RS3 included in this kit has a 2X2 welded wire screen that maintains 90% airflow for maximum compatibility with high efficiency furnaces, hot water heaters and boilers (especially during winter). This screen will provide protection from lawn debris and outdoor animals that include the following:

  • Birds
  • Chipmunks
  • Mice
  • Moles
  • Squirrels

The PVS-IS3 vent screen maintains 70% airflow, with its 18×18 mesh screen, which allows more air to circulate than most of the rodent vent screens available. When in use, this screen will provide the same protection from animals as the PVS-RS3 does and also guards against bugs. When installed, the PVS-IS3 will protect your ventilation system from:

  • Ants
  • Bees
  • Beetles
  • Cicadas
  • Grasshoppers
  • Mosquitoes
  • Moths
  • Wasps

When you purchase the American made PVS-IRS3, you are getting the best flowing vent screens available for your high efficiency furnace, hot water heater or boiler.
