For incineration filtration, chemical resistance and emission control usually matter more than choosing the lowest initial price.
The buyer’s request became more useful once gas chemistry and emission requirements were included.
Problem
The buyer needed better emission control and chemical resistance for a waste incineration baghouse.
Solution
The working condition request included acid gas exposure, temperature, reagent injection, emission target, and current bag failure symptoms.
Result
PTFE membrane PPS and full PTFE options could be compared by performance and cost before sample approval.
