Livestock and Clean Air 

The prevention and control of animal infectious diseases in livestock has attracted more and more attention since the animal husbandry has developed from individualization, decentralization to scale and intensification. Animal infectious disease refers to an extremely contagious disease caused by pathogenic microorganism. Most of them can be transmitted rapidly and on a large scale by direct contact (animal to animal), indirect contact (airborne transmission, feed, water source, etc.) or vertical transmission (mother to offsprings).

Among them, airborne transmission is the main route of pathogenic microorganism transmission. The pathogenic microorganism pass through droplets from diseased animals or attached to dust particles in the air,then rapidly enter and spread the whole farm and even the whole area along the airflow, so as to form a large-scale of epidemic outbreak and bring great economic loss to the livestock industry.


Many pathogens can spread long distances through the air:

●9 kinds of Foot and Mouth Disease (FMD) virus can spread more than 40 km.

●Infectious endemic pneumonia can spread 3 km.

●Transmissible Gastroenteritis of pigs (TGE), Atrophic Rhinitis (AR) and Contagious Caprine Pleuropneumonia can spread more than 1 km.

●Porcine Reproductive and Respiratory Syndrome (PRRS) can spread more than 3 km.

●Swine Influenza Virus (SIV) can spread 6 km.

●Pseudorabies Virus (PRV) can spread at least 40 km.


The air filtration system can effectively prevent pathogenic microorganisms from air transmission

According to a large number of studies, it is confirmed that dust particles or other biological aerosols in the air can be captured by an effective air filtering system, therefore to block the spread of pathogenic microorganisms, prevent and control the spread of disease and epidemic outbreak.

Scott Dee, a professor of veterinary medicine at Minnesota University verified that under laboratory conditions, a pig house with air filtration system had not been infected from diseases after running for 4 consecutive years, and under commercial conditions of high-density breading area, the filtered boar house and sow house have been free from PRRS infection for 6 years and 3 years respectively.


Negative Pressure Air Filtration System

The goal of KLC is to provide effective and reliable clean air filtration solutions for animal husbandry industry, thus to ensure the safety of breeding and to reduce livestock and poultry infectious diseases. KLC's R&D team has gone deep into the industry, understood the difficulties and needs, and successfully developed our air purification technologies and products that are more suitable for the livestock industry.
