CO2 concentration increases due to:
Poorly ventilated areas
Combustion of fossil fuels
Human respiration
Exposure to elevated levels can lead to
hypercapnia, resulting in possible death

None
None
10,000
Low
Slight drowsiness, headache
20,000
Medium
Chest heaviness, more frequent and deeper respirations
30,000
High
Breathing rate doubles, heart rate increases, risk acidosis
50,000
Critical
Sensory dysfunction, unconsciousness, death

SAM filters can detect various gases
including CO2 and refrigerants
Detects leaks sooner and at lower
levels to avoid air quality fines
Section 609 of EPA’s Clean Air Act
allows for fines of $32,500 per day!
OSHA Indoor Air Quality Standards

SAMURAI: SAM Unit Redesign and Integration
Fully integrate Windows CE environment
Develop remote configuration application
Create peripheral interface board
Develop standalone remote monitor with LCD
Design power inverter for pump
5
Final product has the potential to save lives
Opportunity to give new face to product line
Installation cost is currently too high for some
customers
Reduce operating costs by eliminating avoidable
fines
