The Brewer Ultimate Flue Outlet is a static anti downdraught chimney cowl suitable for use with gas, oil or solid fuel fired appliances. It is available in both round and square versions.

This model comes with a mesh pre-fitted which is suitable for use with oil or gas fired installations. This cowl can also be used on solid fuel installations by removing the mesh and activating the upstands to provide the increased airflow required.

The Ultimate Flue Outlet (UFO) when originally introduced in 1995, was the first gas chimney cowl in the UK to pass the vigorous requirements of BS7 15:1993 (200mm). Its ever increasing market share is testimony to its extensive benefits, advantages and superior antidowndraught qualities over other cowls.

The UFO MKII cowl incorporates four adjustable upstands that address the need for a greater exhaust area demanded by the use of solid fuels. The compact nature of the UFO MKII means it can be used on several pots on the same stack without modification, something some other cowls cannot achieve.
