AIR FILTER FOR VAUXHALL | ASTRA MK IV | 1.6 | Year 00 - 05 | 85 HP

The world’s best performing high-tech air filter. There are no other air filters produced using our patented technology, which consists of a single layer of an exclusive polyester fabric. The fabric is formed by woven threads having a diameter starting from 22 microns to 70 microns each, thereby creating a filtering mesh of 37 microns to 85 microns. The filtering material is positioned between two special steel alloy meshes that are treated with epoxy resin. The steel alloy mesh plays an important role by guaranteeing resistance to fuel fumes and moisture while ensuring a clean supply of filtered air for years to come. The steel alloy mesh also withstands the considerable mechanical stresses arising from the pulsating flow of air. Due to its uniform structure, the Sprint Filter air filter offers a consistent flow of filtered air with less of the flow being disturbed from the degradation of filtering material. Further, due to the fact that patented filtering material is designed in a single-layer, the filter is not affected by the “accordion folding” thereby allowing turbulence to be minimized to zero over the entire air filter section, assuring optimum performance from the air box.

Test:

Every Sprint Filter air filter is extremely permeable allowing for laminar airflow because its single layer filtering element is not influenced by the pleats. Further, the upstream and downstream pressure differences created during engine operation, will not affect performance.

Polyester fabric is stable and is not affected by folding during construction. Cotton filters, on the other hand, have a weaving that depends on the overlapping of numerous layers, leading to poor flow in some areas and ineffective filtration in others.

The filters were then further tested by the University of Wales Trinity Saint David to perform a comparative test on performance air filters having fabrics of two, three, and four layers of pre-oiled cotton along with different types of sponge air filters.

The data revealed that when compared to the original equipment air filters, the two cotton air filters had an increase in load loss of 27% for the 4-layer cotton air filter and 34,5% for the 2-layer cotton air filter while Sprint Filter’s P08 filter recorded a 37% decrease in load loss.

P08:

Filtration of 80-micron particles, with a guaranteed airflow of 5,050 l/m2sec, is an amount unattainable by filters using other materials. These figures make the P08 a very versatile and efficient air filter with outstanding performance characteristics, suitable for use on the road. It retains a filtration efficiency of 93,13% of 100 microns particles.

P037:

The P037 is the only air filter in the world with water resistant characteristics. The weave of the fabric guarantees a filtration power of 37 microns, that combined with its water-resistant properties, makes this type of filter particularly suitable for use in demanding conditions. Moreover, the guaranteed airflow of 4,500 l/m2sec ensures nearly the same power increases of the P08. It retains a filtration efficiency of 91,8% of 37 microns particles.

P08 F1-85:

Developed and used by the leading Factory Teams, P08 F1-85 is the latest technological advancement from Sprint Filter with the highest existing permeability of any air filter on the market, guaranteeing a filtering power that makes it even more exclusive. Born for racing, but with special Sprint Filter technology it can also be used on the most sophisticated latest generation super sport bikes and cars, or current production road vehicles without needing carburation adjustment by remapping the ECU or additional control units. It retains a filtration efficiency of 95,22% of 100 microns particles.
