Spring Maintenance - Industrial Fans and HVLS Fans Spring is a great time to perform annual maintenance on most all air moving equipment used for building comfort ( hvls fans, directional fans, mobile fans, exhaust fans, supply fans).  Now is the best time to identify issues that may result in essential comfort systems failing when they are needed the most. Remember, summer is the peak season for parts, service and new products. Most industrial grade fans made by leading USA fan manufacturers require limited ongoing maintenance.  Maintenance details are usually accessible in the installation/operation manuals that accompany the equipment when...

Importance of Industrial Fans and HVLS Fans During Winter Months. Industrial fans and commercial fans have become a common part of most industrial and commercial spaces.  When summer temps make us uncomfortable, our first reaction is to turn on/up our industrial fans or install additional industrial fans.  As we approach the colder Winter months, we need to remember industrial fans and commercial fans also do an excellent job keeping employees warm and saving money on energy bills.  Maintaining a comfortable indoor environment during the winter months comes down to five primary factors: Building Volume – The larger a building is,...

What is a “Sweating Slab”? Believe it or not, concrete slabs can sweat and this is a well documented phenomenon.  Most simply stated, concrete sweating (aka “sweating slab syndrome”) refers to condensation the develops on the surface of a concrete floor inside an industrial building, not subjected to outside weather conditions.  Why Do Concrete Slabs Sweat? Condensation collects on a concrete slab because the temperature of the slab is at or below the dew point temperature of the ambient air inside the building.  This situation occurs most often during times of the year when outdoor temperatures can change by 10F...

It is essential to maintain a fresh air supply and air movement in work areas to keep employees healthy. Too much exposure to contaminated air can cause many health issues. U.S. laws regulate specific air quality in the workplace to reduce the health risks erupting because of inadequate airflow and ventilation. Poor ventilation and airflow can cause stale warm air – a breeding ground for bacteria and other contaminants. Bacteria and pollutants from poor air quality can cause breathing issues and illnesses. Common signs of poor air quality from lack of air circulation health-related issues are headaches, nasal congestion, wheezing,...

AMCA (Air Movement and Control Association ), recently commissioned a simulation study presenting how the operation of circulating fans within warehouses may impact airborne particle and aerosol transmission.  The purpose of the study was to improve the body of Covid 19 guidance in relation to circulating fan use and operation.   Study Background The principle investigator of the study was Dr. Liangzhu (Leon) Wang, PhD, PE, who is also an Associate Professor of Concordia University’s Department of Building, Civil and Environmental Engineering.  Dr. Wang was assisted by a several other research scientist, engineers and other industry professionals(a full list can be...
