To earn a UL certification, the entire manufacturing process, from material selection to product design, has to meet strict guidelines and pass rigorous tests. All testing for AVP's Keepa Vent, Round Back Vent, and Universal Vent were conducted by UL at their testing facilities in Northbrook, IL. The testing protocol was to pass the requirements for the Florida Building Code and the Texas Department of Insurance. The test conducted was the E330 pressure test. 
This test reconstructs simulated high wind environments to examine the performance of the roof vents under extreme conditions up to 230 MPH.

Active Ventilation Products’ off ridge vent product line, the Universal Vent, is a multi-purposed vent that can be used as an air exhaust or intake vent when installed on a sloped roof. This off ridge roof vent or dormer vent has a low profile design that looks pleasing on shingled roofs and parapet walls. Its’ hooded vent design and horizontal louvers will keep out rain and snow. The 1/8 in. opening between the horizontal louvers blades will keep out insects, birds, and animals. When used as an exhaust vent, it is engineered to allow heat and moisture to escape. When placed on the roof but at the low end of a pitched roof, it can be used as an air intake vent like a soffit vent. This off ridge roof vent is also excellent for parapet walls.
