Water Repellent Coating for Air Filters
Nanokote's water repellent coating technologies allow specialised textiles to be functionalised for the purpose of enhancing performance. Functions such as anti-static, dirt and water repellent qualities as well as anti-microbial and flame retardant properties, can be applied to neutralise odours and stop the spread of bacteria, fungi and spores in healthcare facilities.
We have also developed a new water repellent coating that imparts a permanent electrostatic charge to the surface of non-woven air filter media. This new development can dramatically increase the efficiency of low cost filter media. Excellent results have been observed for 100% polyester, 100% polypropylene and PES/PP/PBT microfibres. In most cases we can increase fractional efficiency to more than 90%, which represents an impressive improvement of 40-60%.
Superior Air Filter Solutions
Our specialised water repellent coatings for air filter media can significantly increase the retention of fine dust. Performance is increased due to the use of finer, functionalised fibres and a change in the textile structure. Hence, the net increase in efficiency can be attributed to both mechanical and electrostatic effects. An important feature of the coated air filters is that we can dramatically improve efficiency without negatively impacting the air permeability of the filter media, i.e. there is no change to the pressure drop.
Other functionality that is becoming more important in Green Building design is flame retardant building elements. In the case of air conditioning systems and electrical cabinets, we can now provide added value to the filter media, ensuring the best practice in safe design. In some other air filter applications, it is important for the fibres to remain uncharged, as this application can provide a permanent anti-static solution.
Our value added coatings for air filters are water based and can be easily implemented into existing processing lines.
Some of the filter media applications include:
