The Absolent type Asmoke40 Oil smoke filter features one of the most effective systems in the world for cleaning oil mist and oil smoke. The unit requires very little service: it can run for 1–6 years without requiring a filter change. For Absolent customers, this means extremely low life cycle costs. The Asmoke40 filtration unit is designed for handling the most demanding applications, for air flows of up to 4000m³/h.


No more slippery floors and dangerous smoke. Only 3 teaspoons per year remain. And clean air!


The HEPA H13 filter guarantees clean air – always. Only the best is good enough!


Our unique filter cassettes capture all particles – giving you 1 year of maintenance free operation.


Long useful life and high collecting efficiency

The Absolent filter unit offers a long useful life as well as consistently high collecting efficiency, thanks to its design and generous filter surface measuring either 105.9m² (standard) or 117.9m² (special requirements). Already after the second, self-draining Absolent filter, the particle level in the air is in most cases less than 1.0mg/m³.
The Asmoke40 is equipped with a third filter stage, a so-called HEPA filter, which ensures a consistent collecting efficiency. Thanks to these three filter stages, the air can usually be returned to the premises. This means less loss of energy and more balanced ventilation in the premises.


The Asmoke40 contains an electronic manometer, which shows the filter unit’s time of operation as well as the state of the filter cassettes. The unit has spacious doors for safe and easy service. The pump and control box are built-in and the filter unit is ready to start – just connect it electrically and to the air duct. That’s why we call it a ”plug and play unit”.


The filtering process occurs in three stages. The first and second stages consist of the self-draining Absolent filters, in which the filter material is adapted and mixed specifically for each application. The third stage consists of a HEPA filter, which has a guaranteed consistent collecting efficiency of at least 99.97% arresting 0.3μm dia. particles. Thanks to the unique design of the filter, the Absolent Asmoke filter can be operated continuously without unnecessary interruptions for draining. The return oil is collected at the bottom of the filter for recycling.
