Why is an Air Filter necessary?
The Air Filter is designed to protect the engine from direct contamination by external pollutants. An engine’s air intake is between 200 and 500 m
3 of air per hour, depending on its cubic capacity. The absorbed air is full of impurities depending on climate, ground surface, level of atmospheric pollution etc… In addition there is dust which, if mixed into the engine oil, eventually becomes an abrasive paste, lethal to the engine.The PURFLUX know-how
The very high quality of paper used in Purflux products is specially embossed in order to ensure optimum spacing of the pleats, and maximise the usable surface area. This together with the quality and consistency of paper impregnation ensure the maximum level of dust retention in the filter and air flow to the engine. Purflux products are manufactured in highly controlled conditions, ensuring dimensional stability, perfect fit into the filter housings, and no by-pass of unfiltered air around the filter.
Why replace the Air Filter?
Regularly replacing the Air Filter ensures:
- Maintenance of vehicle performance and Fuel Economy
- Optimum engine output
- A better protected and less environmentally polluting engine (and consequently an acceptable level of exhaust emissions for anti-pollution regulations.)
When should the Air Filter be replaced?
It is important to adhere to the vehicle manufacturer’s recommendation. Purflux recommends replacement of the air filter at least once per year, preferably at the same time as the oil filter.
