Arioso™ microporous membranes are composed of ultra-high molecular weight polyethylene (UHMWPE) and manufactured by a patented process. UHMWPE gives Arioso™ outstanding mechanical strength and chemical inertness. Possessing a unique filtration structure consisting of a micro and nano fibrillar multilayer network, Arioso provides exceptionally high filtration efficiency at an extremely low resistance to air flow. Providing 100% mechanical efficiency, this media does not rely on an electrostatic charge to collect particles from an air stream. Yet, because of its unique structure, it will greatly reduce the force required to move air through a filter when compared to other traditional mechanical filter media. In addition to reducing energy costs, Arioso’s versatility enables it to be designed in to wide range of filter configurations and applications.
Attributes:
•Porosity: Arioso™ membranes are highly porous, over 90% in certain grades. This results in high permeability and low resistance to flow.
•Unique structure: The micro and internal nano fibril multilayer network provides exceptional particulate collection efficiency. The structure is unique in its combination of depth and surface filtration and creates a surface loading structure for larger particles resulting in high dust rejection for dynamic applications. The fibrous structure is 3-dimensional and allows for high capture and holding capacity of smaller particles not filtered on the membrane surface.
•Non fiber releasing: Arioso™ is a continuous network of polyethylene fibrils. It is non-fiber releasing and offers very high strength and durability in comparison with other membranes.
•Durable: Arioso’s exceptional mechanical strength makes it ideal for filters that require dust release during back pulsing.
•Inert: UHMWPE gives Arioso™ its outstanding resistance to most chemicals (including solvents).
•High purity: The polyethylene membrane material has a very low extractable content.
•Environmentally Friendly: UHMWPE membrane contains no fluoropolymers and is more easily disposed and incinerated when compared to other conventional membranes.
•Water repellent: The polyethylene based membrane is hydrophobic by nature.
•Hydrophilic and oleophobic: These treatments are available when required. Additional treatment technologies are under development.
•Backer/Support: A wide range of backers are available for your specific pleating and application requirements.
