PRRS is a highly contagious disease causing enormous economic losses for pig producers worldwide. The risk of infection is particularly high in regions with a large livestock density and the virus can be transmitted from house to house via the air and is able to cover distances of several kilometres if there is a light breeze.
The APT 1500 filter is used with a positive pressure ventilation system and is designed specifically for wall inlets with an air capacity of 1,500 m3/h. Filtered fresh air is pushed into the house by means of an integrated fan. The new PRRS filter is the first system for decentralised fresh air distribution and can thus be retrofitted for existing houses. It consists of a combination of two separate filter inserts and the cassettes can be replaced during operation. No unfiltered air enters the house during this time.
Analyses by the University of Leipzig have shown that the Big Dutchman product can filter up to 95% of PRRS viruses. Other airborne pathogens are also filtered from the air.
