Synthetic fibre media – YAFI FM
Made from 100% polyester fibres in a non-woven structure, suitable for a wide range of air conditions. The media consist of highly elastic, tensioned, randomly arranged fibres. As the fibre thickness decreases, the filter medium becomes denser and finer towards the clean air side (progressive construction), achieving a high level of separation and a large dust holding capacity. Non-flammable, self-extinguishing and harmless to health.

Synthetic fibre media – Description
Made from 100% polyester fibres in a non-woven structure, suitable for a wide range of air conditions. The media consist of highly elastic, tensioned, randomly arranged fibres. As the fibre thickness decreases, the filter medium becomes denser and finer towards the clean air side (progressive construction), achieving a high level of separation and a large dust holding capacity. Non-flammable, self-extinguishing and harmless to health.
Applications
Pre-filter for all types of air conditioning and ventilation installations.
Benefits
- Secured by a progressive fibre distribution
- High dust holding capacity at a low pressure drop
- Non-flammable, self-extinguishing and harmless to health
- Available in rolls or cut to size
