Round air cleaner for excellent flexibility

The compact ENTARON HD two-stage air cleaner is roughly one third smaller than comparable air cleaners with a similar separation efficiency and is therefore one of the smallest air cleaners in its class. In the long term MANN+HUMMEL will replace the proven Europiclon with this range. The ENTARON CD is designed as a single-stage alternative to the ENTARON HD and is therefore the preferred solution for stationary applications with a low to medium dust load (e.g. compressors and power generators). In comparison to the Europiclon the installation space can be significantly reduced retaining the same low flow resistance.

Powerful details

The best choice for each application

The ENTARON HD and CD air cleaners enable a perfect solution for each application. The ENTARON HD two-stage air cleaner is particularly suitable for applications with high dust loads. The single-stage ENTARON CD with low flow resistance and reduced operating costs is suitable for low to medium dust loads. Another benefit of the ENTARON CD is the simplified installation of the air cleaner on the raw air side which does not require any ducts.

Both air cleaner versions offer a high separation efficiency and compact design. The housing concept consists of three plastic parts: A special welding process reliably joins the raw air inlet to the air cleaner body. The gasket inserted in the cover protects against water ingress and prevents the entry of hot intake air from the engine compartment to enable a reliable function. The innovative housing concept allows adaptation of the air cleaner to almost all installation situations as practically all orientations of the inlet duct relative to the integrated brackets are possible. The fixing of the air cleaner can be made using through-holes or threaded inserts. Additional flexibility is provided by the possibility to configure the raw air inlet in a mirror image position and also a selection of welded clean air connections comprising a 90 degree elbow which can be positioned (depending on model), a MAF connection and inch and metric connections.

Innovative evolution

The ENTARON HD achieves excellent separation efficiencies due to effective pre-separation through tangential air flow and optimum filtration with high-performance media. This is despite the fact that the air cleaner requires only small installation space. In comparison to air cleaners with a similar filtration performance the air cleaner is approximately 30 percent smaller and is therefore one of the most compact air cleaners in its class. This is made possible by its design and ingenious solutions such as the integrated and protected service connection which requires less installation space.

Perfect control

The right relation between the volume of air and fuel is crucial for an environmentally-friendly combustion process and economical engine operation. The ENTARON HD is well prepared for an MAF sensor. In order to ensure the best signal quality at all times, the secondary element is equipped with a key lock function which defines the installation position and therefore the right air flow.

The three-part housing concept offers excellent flexibility for the positioning of the inlet angle relative to the integrated bracket and therefore simplifies use for OEM applications.

Service switch

The ENTARON HD/CD has a connection for a service indicator which is directly integrated in the housing. The connection is designed to use a minimum of installation space and is located in a protected position.

Prepared for MAF sensor technology

Due to the defined installation position of the secondary element and optional welded clean air outlet, the ENTARON HD is perfectly designed for a MAF sensor with excellent signal quality.

Main element

The innovative filter media offers a high separation performance simultaneously with an exceptionally long service life. The filter element is equipped with a new gasket system which ensures the reliable sealing of the element to the housing. The main and secondary elements are metal free and are fully incinerable with low-cost disposal.

Comfort fasteners

During servicing the snap-in function of the comfort fasteners prevents pinching between the cover and housing. The distinctive color-coding of the fasteners enables a reliable service even when visibility is poor. In order to meet special installation conditions, the fasteners can be freely positioned on the cover according to the customer needs.

Secondary element

The center tube of the ENTARON HD fixed to the housing protects the secondary element, defines the installation position and prevents unintentional removal or incorrect installation.
