Screened Cowl Vent

Grey PVC vent with insect screen. 4 inch BSP threaded shaft, fitted with two PVC nuts, one with a conformable foam washer. Grey PVC cowl over screen.

These vents are designed to allow air to flow in and out of a large water cistern as the water level changes, while preventing insects from entering. They comprise a shaft made from 4 inch BS Class E PVC pipe, available in different lengths to give an adequate stand-off for different thicknesses of insulation. The other end has a plastic carrier solvent welded to it, which holds a 57 micron stainless steel mesh insect screen. The screen is held in place and protected from falling dust or rain by a plastic cover that can be removed to allow the screen to be cleaned or replaced.

These vents are available in two types: The first has a threaded shaft and is secured by 4 inch BSP nuts. This type requires access to the interior of the cistern for fitting. The second is supplied with NP10/16 PVC bolted flanges. This type can be fitted from outside the cistern.
