ERGIL Storagetech™ Free Vent (Capped Type)

ERGIL Storagetech™ Free Vent (Capped Type)

Model No:150

ERGIL StorageTech™’s Model 150 Capped Free Vent is installed in low-pressure atmospheric storage tanks that contain non-vaporising products. It allows the unrestricted movement of air in and out of the vessel and prevents damage due to over or under pressurisation. The vent should be installed on the tank roof flange located at a high point on the tank, and is supplied with an earth point, copper tag and cable.

A cap and screen protects the vent and restricts dust, wind, rain, or insects from entering degrading the product. No routine maintenance is required to ensure continuous and effective operation.
