Air and Gas Filtration

Invisible yet Crucial – Clean Air for Life

The Rain Forest – a Giant Air Filter

“Our purpose at heIsa® Functional Coating is very simple: We want to help you to build and grow your business. In order to do that, we strive to be technology leaders with our SORBEXX® and COMP-FLEX® products. We have brought together molecular filtration and diaphragm competence under one roof heIsa® Functional Coating. Specialised development teams, working together across disciplines and our various manufacturing processes in harmony with our customer service department constantly work to find the best technical solution for you - our customer.

As a small example, we have recently developed a completely new activated charcoal multilayer filter thermoformed in 3D. This new filter generation reduces cost and saves energy. A further contribution to improve air quality globally and to save ressources. Challenge us!”

Gas and Air Filtration Like water and food, air is essential to all life.

Air impurities impair our lives, and in the worst case can make us ill. Effective air filtration is a decisive factor which does not just make life more pleasant, but is also indispensable in many production processes. To clean air effectively and economically requires a thorough process analysis and optimised filter media. In this complex area helsa速 Functional Coating specialises in the production of media for molecular filtration.

System Partnership Approximately 80 different adsorbents, primarily activated charcoals, are presently used for the production of SORBEXX速 filter media. The number of possible applications is permanently extended by a variety of special impregnations against certain contaminations. Knowledge in adsorption, process technologies and refinement of the various production methods are the key elements which create the optimal solutions to complex tasks in molecular filtration.

Development

Unlimited Possibilities, Unique Solutions

The Optimal Selection Adsorbents can be used to remove a wide range of impurities.

Their large inner surfaces are created by an intricate system of pores. The structure of the surface is relevant to the targeted application. The pores in e.g. activated charcoal are of widely differing sizes, so it is possible for different sized molecules to adhere. In contrast, the pore sizes in a molecular sieve are clearly defined. This enables the targeted removal of molecules of a certain size and chemistry.
