Atlantis Advanced 90-Degree Tee Filter Pack for Oil Tank Bottom Outlets

The Atlantis Advanced 90-Degree Tee Filter Pack is a professional-grade, dual-filter oil filtration solution designed specifically for bottom outlet oil tanks. Where a single filter configuration is insufficient, the tee arrangement allows two filters to be installed simultaneously from a single tank outlet — providing enhanced filtration capacity, greater flow redundancy, and improved system protection for demanding heating installations.

The assembly is configured with a 1" shut-off valve as the primary component, fitted directly to the tank outlet. This critical safety feature allows the oil supply to be fully isolated before the filters, enabling safe maintenance, filter replacement, or emergency shut-off without draining the tank. A 90-degree tee elbow connects the valve to the dual filter assembly as the secondary component, providing a clean and space-efficient installation on bottom outlet tanks.

Every component is precision-machined in the UK from a single piece of aluminium billet, eliminating the weak points associated with multi-part assemblies. All seals are manufactured from Viton — a premium fluoroelastomer that provides outstanding resistance to oil, fuel degradation, and biofuel blends, ensuring long-term seal integrity as the industry transitions to higher biofuel content heating oils.
