QUESTIONS & ANSWERS
The Tempest AA48111 oil filter uses a combination of full pleat filtration media and an internal magnetic filtration system to enhance contaminant removal. With approximately 311 square inches of media, it offers one of the largest filtration surface areas in aviation oil filters. This design promotes uniform oil flow while capturing both larger debris and fine metallic particles. The result is improved oil cleanliness and better long-term engine protection.
The AA48111 oil filter includes a built-in magnet that attracts and captures fine ferrous particles that may pass through standard filtration media. These microscopic particles can contribute to engine wear if left circulating in the oil system. By removing them, the filter provides an additional layer of defense beyond traditional filtration. This helps extend engine life and improve reliability.
The full-pleat media design in the Tempest AA48111 oil filter ensures consistent oil flow while maximizing filtration surface area. This construction improves contaminant capture without restricting oil circulation, even under demanding operating conditions. It also enhances collapse resistance, helping maintain structural integrity throughout the filter’s service life. This contributes to dependable filtration performance between oil changes.
The Tempest AA48111 oil filter is engineered with a burst strength exceeding 600 PSI, well above the standard aviation requirements. This added strength allows the filter to withstand extreme pressure fluctuations commonly encountered in aircraft engines. The reinforced canister and improved roll seam design further enhance durability. These features provide added confidence in high-performance and high-stress environments.
The AA48111 features reinforced nut welds designed to withstand significant stress during installation and removal. In testing, the welds are strong enough that the base metal fails before the weld itself, reducing the risk of the nut separating from the can. This eliminates a common maintenance frustration and helps ensure a secure grip during servicing. It also improves overall reliability during routine filter changes.
The Tempest AA48111 oil filter uses a proprietary Spin EZ® solid lubricant applied to the gasket, which prevents the filter from bonding to the engine mount pad. Unlike traditional lubricants that can break down or extrude over time, this solid compound stays in place under heat and pressure. This allows for easier removal during maintenance without excessive force or damage. It helps reduce downtime and simplifies routine servicing.
The AA48111 oil filter features an improved bypass valve designed to meet Continental TCM specifications of 12 to 14 PSI. This helps prevent premature bypass conditions that could allow unfiltered oil to circulate through the engine. Additionally, the integrated housing helps protect against oil outlet restriction in the event of a bypass valve issue. This design supports consistent oil pressure and reliable engine lubrication.
The Tempest AA48111 oil filter features a heavy-duty canister, a powder-coated finish, and a reinforced base plate to withstand harsh aviation environments. Features such as leaf-spring technology provide lateral stability to the filter pack, maintaining proper alignment during operation. The corrosion-resistant materials help extend service life, even in demanding conditions. This robust construction ensures consistent performance throughout the filter’s lifecycle.
