Why choose an electrostatic, washable air filter?
When deciding what type of air conditioner or furnace filter to use, you should keep two things in mind: Airflow and Efficiency. In order to work at its optimum level, the a/c or heating unit requires no restriction to air flow. You should choose a filter that has the least effect on airflow, but removes the most dust from the air. ACI’s electrostatic air filters allow the air conditioning ...

The New Exclusive SRI-MS Reagent Ion: NH4+ and Its Benefits
A novel proprietary method of NH4+ production for IONICON customers In PTR-TOF-MS traditionally H3O+ reagent ions produced from H2O vapor are used. NH4+ reagent ions have been mentioned in literature as being particularly beneficial because of higher sensitivity (less fragmentation) and higher selectivity (higher proton affinity). However, so far toxic and corrosive ammonia was needed for NH4+ ...

Ineffective cleaning in generic baghouses
ABSTRACT: Background In a typical “generic” baghouse application, the cleaning is accomplished by back-flushing the filter with compressed air that travels through an orifice hole in a purge tube (blow pipe) and through a venturi. A typical generic cleaning system allows dust to be filtered at an air-to-cloth ratio of 5:1. That means for every 5 CFM of airflow, there is 1 square foot ...

Advantages of cleaning without a venturi in baghouse collectors
ABSTRACT: Background The cleaning cycle is the most important part of the dust collector because it controls efficiency and media life. In order to clean a row of bags in a reverse pulse jet baghouse first the flow of filtered air must be momentarily stopped and then back flushed or “induce” air to knock the dust cake off the outside of the filter media. A venturi at the top of the ...

Monitoring Air Makes Sense
Did you know that air filters were originally put in air handling systems to protect the life of the equipment, not human life? And that it is not uncommon for air filters to get changed less frequently to save on maintenance costs? Monitoring input from sensors can tell operators when filters and media need changing. We have required food labels that list all ingredients. Why not electronic ...
