Let’s Clear the Air.

Let's clear the air. The role industrial ceiling fans play in aerobiology.

Aerobiology is the study of airborne microorganisms, pollen, spores, and seeds. Aerobiology includes the atomised transmission of disease, both through droplets and airborne means. Before COVID-19, aerobiology was interesting only to the people responsible for keeping buildings safe and healthy. with COVID-19, everybody is thinking about how safe and healthy their environments are, whether at home, at an office, in a supermarket or somewhere else.

In it’s paper “Aerobiology and Its Role in the Transmission of Infectious Diseases”, NIH (National Institution of Health US) reviews many of the aerobiology variables that impact the transmission of infectious diseases. We decided to do a broad-brush review of this amazing article, ending with the role our fans play in keeping air in buildings safe.

Droplets vs. airborne microorganisms

Droplets and airborne microorganisms are heterogeneous and can be generated from infectious people, heating, ventilation, and ir conditioning (KVAC) systems. Because airborne particles can remain airbrone for as long as one week, it is important to do everything possible to prevent the spread if these infectious agents.

How the environment influences airborne microorganisms travel.

Temperature and humidity have a big influence of airborne microorganisms’ ability to travel and stay infectious. Generally, as temperature rises, virus survival decreases.

A building’s HVAC system is a key factor in controlling the transmission and/or reduction of airborne microorganisms. HVAC systems provide for the health, comfort anf safety of occupants by maintaining thermal and air quality conditions that are acceptable to the occupants through energy-efficient and cost effective methods. They control temperature, relative humidity and air currents. Viruses that are spread easily via airborne transmission can be brought into a building by infected individuals and potentially enter the return air system and can be spread throughout a building by the HVAC system.

A typical HVAC system has three basic components:

  • Outdoor air intake and air exhaust ducts and control
  • Air handling units(i.e., systems of fans, heating and cooling coils, air filters, and controls)
  • Air distribution systems (i.e., air ducts, diffusers and controls, return and exhaust air collectors, grilles, and registers, return and exhaust air ducts and plenums).

The role of an industrial fan.

At MegaFan Technologies, we are committed to work-environment safety and improving out customers lives. As the UK’s largest HVLS destratification fan company, we offer these features, which are designed to reduce the flow of airborne microorganisms.

Through air circulation

  • Mixes trapped warm air from the ceiling with the cooler air below, helping to keep everyone comfortable.
  • Leades to more effective removal of pollutants
  • Reduces the liklihood of experiencinf “sick building syndrome”.

Elevated air speeds

  • Create a perceived cooling effect during warmer months, having a positive impact on productivity and employee morale.
  • Decrease the transmission of airborne disease by reducing moisture accumulation that spreads germs and bacteria.
  • make it more difficult for contaminated droplets to find a path to uninfected people.

High volume, powerful air flow

  • Can cool 22,000 square feet!
  • 1 MegaFan vs. 34 small industrial fans
  • Maintains energy efficiency

Reduced Humidity

  • Reduces the likelihood of having damages products and equipment
  • Decreases the chances of slipping hazards.

We are here to give you and everybody in your building unequalled peace of mind.
