Description
Clear View Filtration’s Patented Dual Filtration Oil Filter Assemblies are the Best Oil Filtration System on the market. When using the See Through Filter and an additional filter on the bottom the user is able to filter the same particles as a disposable would but with the added ease of being able to monitor the engine without taking or cutting anything part.
The 4” Screw-On Filter Series (both Part #400’s & Part #405’s) of Filters can be used on most Big and Small Block Engine combinations, including Street, Dirt and Marine use. This filter is the best choice for motorsports ran on dirt and other applications where the user wants to filter microscopic and dust particles out of the oil system. Oil flows through the See Through Filter which is equipped with a coarse 115 micron element which traps all the larger particles that can be viewed and inspected while the microscopic particles flow into and get filtered out by the System 1 or Disposable Filter screwed onto the bottom. A shot of air empties the filter in seconds exposing the element and filtered particles without draining or leaking any oil and without unbolting or loosening any fasteners or fittings. Filters are remotely mounted and can work on many applications including diesels. This dual stage filter will extend the life and flow of the disposable filter and still allow visual inspection of filtered particles for engine inspection.
**When Running a System 1 or Other Metal Canister Type Filter ; Part # 400-115 and Part #405-115 are the same filter assembly except:
P# 400-115 filter has a O-Ring Receiver Groove machined in the bottom which helps prevent the disposable filter seal from blowing out. (Note; when using P#400 only a spin on disposable filter can be used)
P # 405-115 filter has a Flat Sealing Surface on the bottom so a System 1 O-Ring or Other Metal Canister Filters can seal correctly.
(Note; when using P#405 either System 1 or a spin on disposable filters can be used)
