Application: Not verified. AirSep housings of this general type are associated with Detroit Diesel, Cummins and Caterpillar diesel installations, but the specific engine application for this unit is not documented and the housing part number is not visible. Buyer must match by collar bore diameter, port sizes, and engine model.

Condition: Used, untested take-out. Chipped paint, adhesive residue, grime and light surface corrosion at the seams and small fitting. Internal media pad visible but not cleaned, serviced, or tested. No clamps, hoses, brackets, vacuum regulator, restriction indicator, or hardware included — you receive only what is pictured.

Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase. Used marine part sold as-is unless otherwise stated. No returns on electrical, used, special-order, or installed parts.

Quote is subject to final fitment confirmation by engine/transmission serial number, part number, photos, and supplier availability.
