Q:
What new technologies are influencing industrial air filter design?
14 answers
Answers:
More familiar with Multi-stage prefiltering devices made up of box/pleated filters--sometimes 3-stage filtering. Also-static recipitators--can reduce bacteria, mold,viruses and more down to one NANO. This would eliminate high replacement costs of HEPA Filters.
~Marketing/Sales, Saint Louis, MO
The upcoming technology is motorbikes and in cars even aerospace shuttles require the best air filter designs.
~Krishna M, Project Manager, Bangalore, India
High efficiency wet scrubbing. New filter medias. Airflow design inside the filter casing.

Q:
Please share with us any “non-standard” applications that industrial air filters have been used for.
8 answers
Answers:
Most filters available cover a very wide scope of applications. There are all types of filters available for all industries. The design concept should be more than just achieving Clean Air. It should also eliminate the number of filters used--decrease replacement --decrease the size of Blowers used -- thus lowering the electrical cost of operation and for new construction or retrofit-decrease the cost of initial construction.
~Marketing/Sales, Saint Louis, MO
Most of my work is non standard. Installing a bag filter with a HEPA secondary filter system on a 300 Ton/Hr.crusher rock box. High efficiency wet scrubber handling lead fume.

FeaturesTop

Q:
What would your design or feature "wish list" be for this product?
16 answers
Answers:
The goal of FILTERING ----ultra fine filtering without increasing the electrical loads from filter collection and eliminate replacement costs. This may require(in some applications) eliminating filter media type filters but no less than utilizing a high performance prefilter device--or device that extends the life of the selected main filter. Maybe a new design effort for Filter Manufacturers Engineers to develop a means to filter without a filter or eliminating the quantity of filters used in a system.
~Marketing/Sales, Saint Louis, MO
High efficiency filter with low pressure drop which is still cost effective. Many new medias being developed with this in mind are very costly and, therefore, filter manufacturers/developers are required to charge prices that are much too high.
~Marketing/Sales, Montebello, CA
I don´t know, but I think that if I was selecting a filter or scrubber equipment I would like to find high efficiency, to be economic, maintenance facilities, spare parts available, that have recycling process materials and minimize wastes.
