Why use nonwovens in filtration?
Nonwovens can be engineered very precisely to meet exact specifications and stringent regulatory requirements for air filtration and liquid filtration.
They are ideal in filtration applications where strength of extremely high temperatures is required but other advantages include, ease of strikethrough, increased efficiency, reduced energy cost, and longer service life.
One of the fastest growing segments, nonwovens have evolved from simply replacing other forms of media, such as paper, cloth, glass and carbon to becoming the media of choice for filtration, including the wide adoption of nanofiber layers and the use of sophisticated hybrid filter media.
The different uses are:
Air filtration
- HVAC - industrial heating, ventilation and air conditioning
- Industrial
- Consumer Products (vacuum cleaners, cooker hoods, PCs, etc.)
- Clean Rooms
Liquid filtration
- Food & Beverage (milk, wine, tea etc.)
- Pharmaceutical/Medical
- Water
- Blood
- Hydraulic
Automotive filtration
- Engine air
- Oil
- Fuel
- Cabin air
Speciality filtration
- Antimicrobial
- Biopharmaceutical
- Dust
- Odour
The advantages of using nonwovens in filtration
- Removal of a wide range of contaminants from water (bacteria, viruses, metals, minerals etc.)
- Uniform structure
- Tear- and puncture-resistance
- Chemical resistance
- High retention capacities
- High air permeability
- Excellent abrasion resistance
- Flame retardancy
- Absorption of fats and oils
- High level of flow capacity
- High tensile strength
