HVAC & Filtration

About hvac & filtration

HVAC & Filtration encompasses components used for air quality control and movement within industrial, commercial, and residential settings. Key components include air filters, which range from MERV 8 pleated filters for general ventilation to HEPA (High-Efficiency Particulate Air) filters for critical environments, rated for 99.97% efficiency at 0.3 microns. Ducting, available in rigid spiral-wound galvanized steel, flexible aluminum foil, or insulated polyester, is specified by diameter (e.g., 6-inch, 12-inch) and static pressure rating. Blowers and fans, such as centrifugal or axial types, are selected based on airflow (CFM - cubic feet per minute) and static pressure requirements, often detailed on fan curves. Dust collection systems integrate hoods, ductwork, cyclonic separators, and baghouses to capture airborne particulates. Fume extractors, often localized, utilize activated carbon filters or HEPA filters to remove gaseous contaminants and fine particulates. Material selection for filters includes fiberglass, synthetic media, and activated carbon, while ducting materials are chosen for corrosion resistance, temperature tolerance, and fire ratings. System design considers air change rates, contaminant types, and regulatory compliance.
