Air Cartridge

Synthetic nanofiber filter media

The cartridge filter is designed on the basis of nanofiber technology, which ensures a high filtration effect. The composite structure of the cartridge filter consists of a spunbond or needled nonwoven fabric and a nanofiber network. Nonwovens and nanofiber networks are combined into one product by a high-quality technological method.

The used joining technique ensures connectivity, adsorption capacity and low pressure drop. Thanks to the unique design, the filters are highly air permeable and at the same time retain polluting particles. The design of the cartridge filter shows excellent resistance to UV radiation and cleaning options.

How does it work

Non-woven layer

Pre-filtration (large particles) prevents damage to nanofibers

Nanofiber layer (PA6 / PVDF)

Fine filtration (small particles), high filtration efficiency and low pressure drop

Non-woven layer

It supports nanofibers, increases the stiffness and strength of the entire composite

The main advantages of our solution

Dramatic improvement in filtration efficiency - the best achievable efficiency for submicron particles.
Low initial and permanent pressure loss.

The top layer prevents depth filtration, captures particles at the beginning.

Excellent mechanical force.
Excellent dust capacity.
Excellent UV resistance.

Unique know-how

The cartridge filter is designed based on this patent:

Patent for the technology of production of composite material - i.e. the production process by which the product is manufactured.

Synthetic nanofiber filter media is produced in several steps:

1. Production of our unique nanofiber surface using electrospinning technology for nonwovens. Electrospinning is a manufacturing process that uses an electric field to control the deposition of polymer fibers on a target substrate. This electrospinning is used to produce nonwoven fabrics with polymer fiber diameters ranging from 500 nm to 100 nm and less.

2. Use of two / three / four layers to improve the mechanical strength and bonding of the final filter medium. The layers are, for example, spunbonds, needled nonwovens, nanofiber active layers, etc.

3. World intellectual property rights to products developed by us.
