Static Pressure Affects Airflow

It’s important to keep HVAC equipment clean and free of built-up dirt and debris. Hygienic duct cleaning and the disinfection of system components are also key to achieving proper indoor air quality. While this step assists facilities managers in their efforts to maintain healthy IAQ for occupants, static pressure is another consideration. Static pressure is used in the area of fluid mechanics. Put simply, it’s the resistance to airflow that occurs in HVAC ductwork and within the system itself. When static pressure is too high or low, this reveals a problem within the system. Identifying a problem allows managers to schedule repairs before a more serious problem occurs. It keeps the system running at peak performance which lowers operating costs. It also lengthens the lifespans of equipment. Static Pressure and How It Affects HVAC Systems From heating and cooling systems in the home to large HVAC units in commercial buildings, these systems all transport air. The ductwork also is the path for airflow in the system. The correct installation of these systems ensures proper operation. However, resistance ...

Air Cleaner Study Finds Reduction in COVID-19 Transmission

With the risk of airborne transmission of the SARS-CoV-2 virus established, homeowners and business owners seek to limit the spread of COVID indoors. This requires a combination of methods and guidelines including increased HVAC maintenance and social distancing. A recent air cleaner study recommends an additional tool in the fight against virus transmission. The findings, published in the journal Indoor Air show that air cleaning devices limit the spread of COVID-19. Therefore, portable air cleaners in residences and commercial buildings are an effective way to reduce airborne viral levels and the transmission of COVID-19. Air Cleaner Study When an individual contracts the COVID-19 virus, self-isolation is key. This prevents the virus from spreading throughout the workplace and other public settings. However, as an individual remains at home, the risk of secondary infection to family and other household members increases. A piece of good news in this regard is a recent study showing a lowered risk of residential exposure through the use of air cleaning technology. As a part of the study, published in April of this year, ...

How Building Particulate Matter Affects People

The COVID pandemic highlights the danger of airborne viruses as well as the need to limit their spread. Viruses, however, are not the only risk posed to building occupants. Airborne particulate matter (PM) poses a significant risk as well. When we breathe in these tiny particles, some smaller than ten microns, we put ourselves at serious risk of respiratory issues. Since we spend 90 percent of our daily lives inside, long-term exposure to building particulate matter is cause for concern. Building Particulate Matter Explained While many people are aware of the dangers posed by building particulate matter, they may not be sure what that means. Particulate matter, or PM, is a mix of particles and liquids. Too small to be seen by the naked eye, PM contains things such as metals, dust, soil, organic chemicals, and acids. When it comes to building particulate matter, size matters. In fact, the smaller the particulate the more danger it poses. Tiny hairs in the nose and mucus in the trachea and bronchial tubes trap viruses, bacteria, and dust. However, particles ...

National Safety Stand-Down Week Is Here

OSHA Safety Stand-Down Week on Fall Protection is May 2nd-6th. This is a national event in which Pure Air Controls participates annually. Throughout the week, all our field services divisions will seize this opportunity to have a Stand-Down, not only for Fall Protection but to address SAFETY OVERALL. Each team will discuss various safety topics (applicable to their area of expertise and job function) and celebrate our comprehensive safety culture. This provides for a more exciting and impactful dialogue around all things safety and aids our teams in having honest conversations about the specific safety principles and protocols that most affect their daily tasks. With the help of our Regional/Business Safety Managers, many activities have been planned, ranging from training sessions to week’s end events. We will also send daily safety tidbit communications to all our field team members! “Lead with Safety” is more than just a motto for Safety Stand-Down Week. It is a standard operating procedure for Pure Air Control Services and all the Tremco CPG businesses. Here is what we stand by. Safety F.I.R.S.T Approach for Safety Stand-Down Week & Beyond ...

Clean Air Challenge: How It Helps Meet IAQ Goals

In March, the Biden Administration released its National COVID-19 Preparedness Plan. The plan provides guidance on the continued fight against COVID-19. A key part of this plan includes the Clean Air in Buildings Challenge. The clean air challenge is for facilities managers, business owners, and other stakeholders to improve indoor air quality and limit the spread of viruses in the buildings they operate. The COVID preparedness plan is another part of the federal government’s efforts to reduce the threat of COVID. Along with the American Rescue Plan, and the $350 billion it provides for state and local governments, this plan seeks to get schools, agencies, and all businesses open safely. Organizations used the money from the rescue plan to inspect, test, and maintain mechanical systems, buy air-cleaning devices and HEPA filters, and upgrade and service HVAC systems. The Clean Air Challenge is another tool to help reduce risk and keep building occupants safe. The Clean Air Challenge As a part of the Clean Air Challenge the Environmental Protection Agency (EPA) worked with the Department of Energy (DOE), ...
