Fabrics sprint filter technology

Fabrics of filters

The common performances air filters are composed of cotton yarn very large, the Sprint Filter polyester air filters instead consist of much smaller yarns and calibrated. Thanks to this type of construction the Sprint Filter polyester fabric allows a better filtration combined with a good air permeability, as shown by tests performed. It is necessary say that as regards the cotton fabric results obtained were not constant, this is due to the weak structure and mobile of cotton gauze, the following data are, however, best obtained. With respect to the polyester fabric data have remained constant and precise.

Airflow sprint filter technology

Air permeability

The uniform and compact polyester filtering element consists of a thin filament of fabric, forming a mesh of several dozen microns, capable of trapping all significant particles and ensuring a very high air flow rate. Our polyester air filter guarantees a very high air flow that neither cotton filters nor OEM paper filters can achieve. Remember this simple equation: More Air = More Power!

Efficiency filtration

The Sprint Filter polyester air filters retain 93.13% of 100 μ particles (Sprint Filter P08 air filter) - 91.8% of 37 μ particles (Sprint Filter P037 air filter) - 95.22% of 100 μ particles (Sprint Filter P08F1-85 air filter) versus the 76.42% of a common 4-layer oil-soaked cotton air filter

Because of its uniform structure, the Sprint Filter air filter ensures less air flow disturbance, also thanks to the exclusive and patented filtering material in single-layer polyester.

Realization sprint filter technology

The realization

Sprint Filter creates over 65 years innovative products made with the most sophisticated and technologically advanced materials: from aluminum, steel, and then move on to materials in polyurethane foams to get to plastics all kinds of fine carbon and kevlar. The entire process of manufacturing our products is done internally with sophisticated equipment design and production: designed with advanced three-dimensional cad-cam our filters and extraction systems are built using molds developed with numerical control machines and realization fine with modern machinery for molding plastics and dispensing of polyurethane.
