WHICH FILTER IS BEST FOR YOUR APPLICATION?


Choosing the best filter for your application depends on what you are trying to achieve. 

If your goal is to achieve the best possible paint arrestance efficiency, then the Andreae High Efficiency Filter is the best option, regardless of coating used.  However, if your goal is to achieve a balance between arrestance efficiency and life of filter, then the drying nature and particulate size of the coating must be taken into consideration.

In general, if the coating flash dries very quickly during the exhaust process, then the Andreae High Efficiency Filter is the best choice.  The Andreae High Efficiency Filter has a polyester backing that effectively captures fine particulates.  However, as with all fibrous media, polyester tends to capture particulates on the surface of the blanket.  Thus life of the filter is greatly reduced when filtering large particulates or those of a tacky nature. 

If the coating is of a tacky nature or will otherwise "face-load" the polyester backing quickly, then the Andreae Standard Filter is the best choice.  The Andreae Standard Filter captures particulates through impaction by way of intertial separation.  In inertial separation, the air stream carries particulates through a maze of filter walls.   Particulates impact on the walls and are deposited in deep holding pockets out of the air stream (thus causing no restriction in airflow).

Benefits include:
  • Holding capacity up to 6 times higher than other filter media
  • In depth loading of the filter:  never face loads.
  • Filtration efficiency up to 99.4%.
  • Particles are retained in pockets out of the air stream:  no migration.
  • Life of the filter:  fewer filter changes means less disposal costs, less labor and more production time.
  • Reduced transportation and storage costs:  the accordion structure compresses 90sf into a 5sf box.
