What are the 3 types of media used in contaminate control - ANSWER✅✅ Active
carbon, chemically treated carbon, potassium permanganate
What is residence time? - ANSWER✅✅ the time it takes air to cross a distance
equal to the thickness of the filter without accounting for the resistance of the media
through which it travels
What are the variations of the contamination control principle - ANSWER✅✅ clean
the air required by the process, blanket the product with cleaned air, offer enough
air flow to move contaminated air away from the product
, What is removal efficiency - ANSWER✅✅ The fraction of the contaminate that once
in contact with the media is removed by either physical or chemical means
What is Capacity - ANSWER✅✅ The amount the media is capable of removing - this
determines the life of the filter
What are two types of filter options - ANSWER✅✅ partial bypass, total retention
What is the ASHRAE standard 62.1/62.2 - ANSWER✅✅ Ventilation for acceptable
indoor air quality to specific minimum ventilation rates IAQ which will be acceptable
to humans and are intended to avoid adverse health effects

What is the min eff for a Super ULPA - ANSWER✅✅ 99.9999% on MPPS
What are the factors affecting ESP design and efficiency - ANSWER✅✅ partical size,
velocity through filter, voltage on ionizer and collector, collector plate spacing,
collector plate loading, ionizer spacing and ozone
What are the types of Microorganisms - ANSWER✅✅ Virus, Bacteria, Fungi
A baghouse is composed of - ANSWER✅✅ house, hoppers, tubesheet and plenum
A typical oil mist electrostatic presipitator has what sections (inlet to outlet) -
ANSWER✅✅ Baffle, ionizer, collecting, fan and optional after filter
PCO has how many types of reactor configurations - ANSWER✅✅ 4
In the filter industry, a manometer is used to measure what? - ANSWER✅✅
Pressure drop across the filter
Airflow through a booth must be? - ANSWER✅✅ high enough to keep the
concentration of VOC vapor below 25% of its lowest explosive limit
ULPA stands for? - ANSWER✅✅ Ultimate low penetration Air Filter
