Municipal Water Storage Tank Ventilation
800.440.6374    Phone 360.835.7507
Above ground storage tanks must be ventilated to allow inward and outward air flow to compensate for the discharge and intake of water according to the supply demands as required by the municipal consumption of water. The screens must allow substantial air flow to prevent storage tank cavitations. Another important function of water tank vent screens is to prevent entry of insects and air borne debris into the drinking water supply.

Chlorine is commonly utilized in municipal water treatment facilities.

These tables provide information based on laboratory tests of the more popular Stainless Steel grades utilized in wire cloth weaving.
Results should only be considered as a guide to the potential service life of woven wire cloth screens.
Secondary fabrication such as welding, soldering, brazing or heat treat processes may have adverse effects on screen life.
