Understanding the Basic Fan Laws

Geoff Edwards, the technical product engineer at Axair Fans UK Limited, explains the three basic fan laws when applied to warehouse ventilation studies. The Fan Laws are a group of useful equations for determining the effects of a change in the speed, the diameter of the fan and the density of air in the system. They are most useful for determining the impact of extrapolating from a known fan performance to a desired performance. So, in short, the basic fan laws are used to express the relationship between fan performance and power. To ...


Why Refurbish AHU’s with EC Plug Fans

Old buildings can often feature outdated and deteriorating ventilation systems. The first opinion may be to replace the entire air handling unit, but often refurbishing the components within the system can prove beneficial beyond financial gain. This week we look at the advantages of AHU refurbishment over replacing the entire system. One major problem in favour of refurbishment is that of the existing system. Ductwork and max air volume delivery are often governed by the existing ventilation system, so the new one must comply with these sp...


Industrial Fans for Dust & Solid Transportation

Industrial and manufacturing processes and procedures can often produce hazardous and combustible airborne particles such as dust. This particulate must be extracted out of the working environment in order to protect other processes and any susceptible personnel. Axair, in partnership with Casals Ventilation, can supply a range of fans that can be utilised in local extract or multi-point ducted systems to remove these particles safely and efficiently. Material handling fans are required where dust, solid and bulky materials need to be handle...
