Fans for Spray Booth Extracts

Manufacturers of spray booths need to ensure that they have effective ventilation for two main reasons; to protect spray booth operators by extracting paint fumes and to ensure the best paint finish possible by removing excess particles of the paint spray. During the spray process, paint particles are released into the atmosphere through the spray nozzle which increases the release of potentially hazardous vapours and paint particles. Professional spray paints and lacquers often contain volatile organic compounds which are emitted as gases. ...


ATEX Fume Extraction for Landfill Organic Waste

Landfill gas is a natural byproduct of the decomposition of organic materials which are put into landfill. The gas is composed of roughly 50% methane (CH4) and 50% carbon dioxide (CO2) and a small amount of non-methane organic compounds. Methane is a potent greenhouse gas and is harmful to the environment. When organic waste is first deposited into landfill, it goes through the initial stages of decomposition where small amounts of methane are generated. As the conditions change during the subsequent stages of decomposition, an increase ...


A Sweet Outcome: Stainless Steel ATEX Fan Case Study

Axair were recently tasked with finding an air movement solution for a major producer of throat and cough sweets. The customer, with a site based in the centre of a rural town, employs more than 200 people and was established over 200 years ago. The Problem A review of the company’s manufacturing processes revealed that the method of producing throat lozenges, using a powered starch mold process, has the potential to cause an explosion. Starch powder, like many food based powders used in the food processing industry, has the potentia...


6 Advantages of Multiple Fans in a Fan Grid / Fan Wall

Multiple fans in parallel vs. a single fan in ventilation systems In many cases, it is advantageous to use more than one fan running in parallel on a fan grid (or fan wall) in a ventilation system to achieve the benefits discussed below. 1. Efficiency Typically 40% of a commercial buildings energy use comes from heating, ventilating and cooling with 50% of the HVAC energy consumption coming from fans. Given the increasing cause for environmental concern, designers should look to select EC plug fans which will not only provide the necessary r...


The Axair team enjoy a customer visit with a difference

After recently supplying the Churnet Valley Railway with industrial fans, the Axair team got the chance to drive and fire a steam engine during a corporate day. They were given control of an American wartime locomotive under the instruction of volunteers Chris Simcock (driver) and Jack Ilczyszyn (fireman). The team climbed aboard the footplate in pairs to blow the whistle, shovel coal into the firebox, open the regulator and experience the power of steam. The Churnet Valley Railway is a heritage line that takes visitors back to the classic d...

The Importance of Battery Room Ventilation

Everyone knows the function of a battery, to store electricity in the form of chemical energy and to convert to electrical energy when required. Vented lead-acid batteries or flooded batteries as they are also commonly known, consist of plates that are flooded with an acid electrolyte. When charging, the electrolyte emits hydrogen through the vents in the battery. Under normal operations, the release of hydrogen is relatively small, but this is elevated during heavy recharge periods. It's an important consideration for battery room ventilation....

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...
