Testing of exhaust air cleaning systems under practical conditions 

DLG TestService tests the fundamental suitability of exhaust air cleaning systems for reducing emissions under practical conditions in pig, cattle or poultry houses.

This means that the DLG test goes far beyond a pure emission measurement. All parties involved – approval authorities, manufacturers and farmers – can therefore rely on the functionality of certified systems when operated correctly.

High importance of testing and certification

The revision of the Technical Instructions on Air Quality Control (TA Luft) has made the testing and certification of exhaust air purification systems extremely important, as only quality-assured processes may be used in systems requiring approval. In this context, the DLG test framework is often cited as a guideline for conducting and evaluating tests.

Convincing advantages

DLG-approved exhaust air purification systems are accepted by building permit authorities.

DLG-certified systems also comply with the requirements of TA Luft (2021) No. 5.4.7.1.
