Pre-filters

Air filtration units are responsible for keeping air clean and healthy, which is particularly important to maintain air quality in indoor environments. With an open, fibrous structure, Daltex® Lowbond™ and Lowbond™ Ultra remove solid particulates from the air and are ideally suited to pre-filter applications.

Providing structural support to the finer filter medium, our materials retain an extremely low resistance to air flow throughout the service life of the filter unit. Manufactured from polypropylene, with a thickness of around 1mm, all our products can be ultrasonically welded into filter housings for easy fabrication.

With facilities to produce both discrete and laminated rolled goods, we can combine Daltex® nonwovens with meltblown for the filtration of very fine particles.

HVAC Pre-filters

Heating, Ventilation and Air Conditioning (HVAC) systems utilise a variety of different filters, including mats, bags, cartridges, cassette and pocket filters. Ventilation systems remove contaminants such as odour, dust and airborne bacteria  to provide high indoor air quality.

Daltex® Lowbond™ and Lowbond™ Ultra maximises and maintains, coupled with superior dust loading capacity, increase efficiency and filter life. Produced from polypropylene and therefore with excellent chemical resistance, Lowbond™ and Lowbond™ Ultra have high air permeability.

Vacuum Cleaner Pre-filters

Currently, vacuum cleaners typically have motors from 1800 - 2200W. Under new European Union rules designed to cut energy use, all new vacuum cleaners cannot have a motor exceeding 1600W. From 2017, the limit will reduce to 900W. In addition, and for the first time, vacuum cleaners will have to carry A - G ratings for energy use, dust emission and noise as well as cleaning performance on hard floors and carpets.

Daltex® Lowbond™ and Lowbond™ Ultra nonwovens both have extremely low resistance to air flow. In vacuum cleaners with smaller motors, the nature of these spunbond materials ensures suction is maintained and that the product meets new legislation. Retained air permeability with very high dust loading capacity can offer good cost savings and help prevent final filter clogging.
