HEATING COOLING DEHUMIDIFYING AIR FILTRATION
What is Air Quality?• “Healthy Air”
– Ambient or indoor air which is free from harmful contaminants and contains 19.5 to 22% oxygen (suitable for breathing)
• “Clean air”– Air of such purity that it
will not cause harm or discomfort to an individual if it is inhaled for extend periods of time
• OSHA Regulations (stds-29 CFR) Ventilation – 1926.57
HEATING COOLING DEHUMIDIFYING AIR FILTRATION
Ventilation Issues• Chemicals/Fumes
– Paints, Glues, Varnishes
– VOCs-carpeting, cabinets, furniture
• Dust/Particulates– Diesel exhaust
– Grinding/Sandingo Silica, Lead
– Weldingo Galvanized steel-CR, NIo Stainless Steel-ZN, flux
HEATING
HEATING COOLING DEHUMIDIFYING AIR FILTRATION
Safety IssuesUse of Outside Air Can Help Reduce Safety Concerns
• Ventilation of Harmful Fumes– Paints, Glues, Varnishes, etc.– 3 main byproducts of combustion
oCO, CO2, H2O
• Carbon Monoxide (CO) Reduction– OSHA levels– Many sources on a job site
HEATING
HEATING COOLING DEHUMIDIFYING AIR FILTRATION
Direct Fired Make-up Air• Pressurizes the structure
– Minimizes infiltration & cold spots
• Uniform heat distribution• Controlled ventilation (0.5-
1.0 AC/Hr)• Absorbs moisture,ventilates
toxic fumes and excessive moisture
• Lowers relative humidity levels and dew point
surface temperatures
