Wavelock the new spin-on filter

MANN + HUMMEL launched its new Wavelock spin-on filter, in order to be always on top in the filtration sector. The innovative WAVELOCK spin-on filter, showcased in september at Hanover IAA , concept enables easy, quick and clean servicing and will definitely be a great ally in off-road applications.


A key element of the design is a bayonet lock which securely joins the filter head to the spin-on filter and simultaneously simplifies servicing. When a filter change is due, the filter can be removed and refitted with an easy rotation movement.

A further advantage is the improved component cleanliness. With conventional systems the thread is milled into the aluminum head. In this process minute residual particles of dirt can stick to the component and cause substantial damage on the clean side of the filter.

In addition, for the purpose of reliability, the Poka-Yoke principle is applied during servicing to ensure that only the right product can be fitted. As a result, they have to be able to reliably withstand pressures of more than six bar.

A modular system

MANN+HUMMEL will in future offer its range of WAVELOCK spin-on filters as a modular system. A number of different variants are planned in the same way as practiced with existing modular systems which have a traditional spin-on filter concept. Possibilities exist to produce an oil filter head, a fuel filter head with and without manual pump as well as a kit for engine components.

It is possible to combine these variants with numerous filter media, anti-drain membranes and bypass valves. The spin-on filters are currently available in size 9 and an extension of the modular system is planned to enable further sizes. The revolutionary filter concept has already been in operation since the beginning of the year for a garden tractor of an US-American manufacturer. There are ongoing tests for further application areas for on- and off-road applications.


FPT Industrial: let’s go, XC13

The XC13 surely sounds agnostic in FPT Industrial’s unofficial nomenclature; it comes, indeed, with a tripartite certification: Euro 6E (winking an eye at the upcoming Euro 7), methane gas and also biofuel, with a link to hydrogen. Andrea Abbà, FPT’s product marketing manager, told us about dialogui...
