Kojen Filtre KD8000 series

KD 8000 series air filter elements meet the most stringent requirements for the newest engines.

Introduction

In recent years, a new type of air filter system has been developed which is now being used in increasing numbers on heavy duty and automotive applications.

This new system uses radial sealing of the air filter elements to a mounting tube which is permanently affixed to the air filter housing.

Radial sealing air filters design is composed by: 1 open cap and 1 closed cap.

Concept

The seal in the air filter housing (mounting tube) is created on the inside diameter (ID) of the open endcap for the primary element or the outside diameter (OD) of the secondary (inner) air filter element.

Standard replacement "axial" sealing air filter elements and "radial" sealing air filter elements are designed to fit and function very differently.

"Radial" sealing elements cannot be mixed with conventional "axial" sealing elements. Radial sealing elements cannot be fitted into housing unless it is equipped with the proper mounting tube.

By the nature of their design, radial sealing elements are self centring and self aligning.

Radial sealing air filter systems offer several advantages, but because of their unique design, they also have some special service tips and procedures which should be followed.

Mounting tip #1

The cover of the air cleaner housing must be reinstalled after the filter element is serviced. The cover plays no part in sealing the element to the housing, but does prevent the element from moving from its mounting tube.

Mounting tip #2

The element should be fully inserted onto the tube before the housing cover is replaced.

Do not use the latches of the housing cover to force the air filter element onto the mounting tube. Generally, dry lubricants such as baby powder or talcum powder, or silicon’s are used if they are necessary for installation.

Construction

End caps: Filter media is directly installed in a mould filled by POLYURETHANE (PUR) to obtain perfect bonding thus a zero by-pass cartridge filter

Outer and Inner Screens: Hot-dip Galvanized Perforated and or Expanded Steel to ensure a high mechanical strength

Gaskets: No extra part added as gasket is part of the cap

Media: Filtration is provided by high quality cellulose-based TURBOPAPER impregnated with special resins to achieve high filtration standards, high dust holding capacity and low initial pressure drop

Media stabilization: Pleat lock stabilization (PLS system) to maintain uniform spacing between pleats as standard

Inspection: Individual inspection of each filter prior to ship
