We manufacture the main filtration layer for medical masks, respirators and composite for pocket or pleated air filters from synthetic materials containing – fibers produced by the “Meltblown” technology. Due to the large selection of materials and the versatility of the equipment, we can adapt to the customer’s wishes and produce quality products.

To check the quality of production, we use special measuring devices inside the company, thanks to which we can ensure that each product will meet all the requirements of ISO standards.

Composite for pocket filters. It is a compound of synthetic non-woven materials for the production of pocket air filters. The products trap dust, insects, fluff and pollen. This type of composite is joined in dots by strips of the required width with an ultrasonic composite machine. We can adjust the width and number of strips according to the customer’s requirements. The maximum total width of the product is 710mm. The composite consists of:

Outer layer. Spunbond non-woven material made of polypropylene granules.

Filtering layer. A non-woven material with a filtering function made by the “Meltblown” technology. Depending on the customer’s request, we can produce Melt Blown polypropylene:

various filtering classes;
without electric charge;
using electric charge: can be charged by corona method or using water;
density from 5 gsm to 100 gsm.

Pre-filter. A non-woven material made of polyester granules that traps dust and extends the filter layer’s clogging term.

We have several types of pre-filters in our range that the customer can choose from. We also produce a composite of increased stiffness and economic class pocket filters without a pre-filter.

The filtration efficiency of this type of product has been determined in the certified laboratory “Eurofins” in Finland.
