Benefits of Cavitec™

The Filtrona Cavitec™ filter comprises of two separate filter segments surrounding a cavity containing granular activated carbon. A unique characteristic of the Cavitec™ is that it allows the cavity to be filled with more than one granular additive. This can be in combination with different segment materials for maximum filtration flexibility.

The distinct benefits of the Cavitec™ filter are:

• The use of any granular adsorbent and excellent flexibility of the triple filter promotes the development of a unique selling point and brand differentiation possibilities

The Filtrona Cavitec™ filter also offers a number of other key benefits:

• Industry leading volumetric cavity fill, ensuring optimisation of additives effect
• Capability for high levels of additive loading
• The activated carbon results in a reduction of vapour phase and semi-volatile components in mainstream smoke without the need for ventilation
• Flexibility to balance the taste and smoothness of the tobacco to suit the customers’ requirements
• Flexibility for one or more adsorbents mixed into the cavity
• Clean run product offering a production environment free from contamination when segment are not loaded with carbon
• Possibility of including granular additives in tobacco end segment for maximum loading 

Construction of Cavitec™

The Cavitec™ filter consists of a tobacco and mouth segment of high-quality crimped acetate surrounding a central cavity. The tobacco segment can be loaded with activated carbon or constructed from paper to further increase the flexibility of this filter. The cavity is filled with granular activated carbon and this can be combined with other suitable granular adsorbents as desired.

The outer two segments and the cavity are wrapped in plugwrap, which can be either standard or porous depending on ventilation requirements. The central cavity is created as the filter segments are wrapped in an outer plugwrap which can also be standard or porous depending on the required ventilation. 

A wide range of configurations, lengths, circumferences, and additive loadings and types can be selected. This ensures each construction is precisely designed to suit the taste and filtration requirements of the customer and enhance a particular brand.
