Functional description:

The acid filter is designed for the removal of aerosols from the gas flow of predominantly emission measurements. This deals with floating liquid droplets (aerosols), which are deposited in a specially built filter matrix. This takes place with high efficiency because the gas flow is directed from inside to outside by the filter body. Here, the small liquid droplets are coalesced until large drops have formed, which sink in the filter element as a result of gravity and accumulate at the bottom of the glass tank. The service life of the filter element depends on the load of the measuring gas due to solids.


Installation of the acid filter in front of the measuring gas cooler.The acid filter must be mounted vertically. The condensate should be able to accumulate in the lower part of the glass tank. The gas connections are marked with arrows. The measuring gas outlet allows a variable immersion depth of the Teflon hose. The deposited liquid is carried along by the measuring gas outlet of the acid filter to the measuring gas cooler. For this, the hose must be inserted in the measuring gas outlet up to a few mm below the lower edge of the filter element in the flask (see image).

Gas flow diagram:

In case of large condensate quantities, the condensate can be disposed of manually using the optinal connection or using
an additional peristaltic pump.
