Notes from the specification desk
Short, specific answers to the questions that come up before an order — and after a failure. No listicles, no “ten reasons to choose us”.
How long should a filter bag last in a medical waste incinerator?
Two to four years is achievable in a well-run baghouse and nine months is common in a badly run one. Here is what separates the two, and how to read a failed bag to find out which problem you have.
PPS vs PTFE vs fibreglass for incinerator flue gas
Temperature gets the attention, but acid dew point, oxygen and moisture decide. A worked comparison for the three media most often quoted for incinerators.
Why pulse valve diaphragms fail early — and what to check first
Five causes in the order worth investigating, how to tell them apart from the failed part, and when NBR is simply the wrong elastomer.
Choosing filter media by dust type: a one-page decision path
Start with temperature, then chemistry, then abrasion. A practical sequence that avoids the most expensive mistake — buying the cheapest bag twice.
