Fans for School Fume Cupboards

During school science experiments and demonstrations, it is commonplace to use fume cupboards. School fume cupboards are designed to capture and remove air-borne hazardous substances generated during laboratory experiments to reduce the risk of exposure to a safe level. These include harmful gases, vapours, aerosols and particulates. Fume cupboards prevent potentially dangerous vapours being released into the classroom in two main ways; through ducting or through filtered, recirculated air. Ducted fume cupboards draw air through the sash ope...


The Growth of EC

Historically, AC motors were used as the principal air driving force in HVAC applications running constantly at full power. The continuously increasing demand for a more energy efficient solution with a greater range of operation possibilities led to the development of the Electronically Commutated (EC) motor. Since its development in the 1960s, EC technology has steadily grown market share and replaced AC technology in many air movement applications. Due to the substantial energy efficiency improvement in motor technology that EC offers, it...


Influence of E-Wheel Efficient Impeller: Noise and Energy

With an ever growing focus on system efficiencies, manufacturers of industrial equipment must take into account individual components to ensure that these key influencing factors achieve the desired energy savings. Replacing inefficient components that are often overlooked in ventilation systems, can result in sizeable gains. A significant component in such systems is an efficient impeller. Noise Attenuation Driven by an increased market requirement concerning noise levels, the new E-series impeller design produces major reductions in operati...


The Axair Team Scale Scafell Pike

Scafell Pike is England’s highest mountain and stands at 978 metres above sea level. The Axair team took it upon themselves to scale its heights this summer and the task proved to be an excellent challenge. Taking the path from the starting point of Wasdale Head up the western side of the mountain, the team set off armed with sun cream and sandwiches. The footpath led through Lingmell Gill and Hollow Stones. Glances back down the path afforded impressive views of Wast Water. The path soon steepened and the ground became rockier underfoot a...


Axair Support the Kidsafe Schools Initiative

Helping children learn how to be safer in everyday situations is a key issue for parents and teachers alike. The Kidsafe approach is committed to making children more aware of, and so more prepared for the dangers they may face. Integral to their philosophy is the idea that learning should always be fun and not dampen children’s sense of adventure. To that end, the Kidsafe initiative aims to get important safety messages across to school children nationwide in an interactive, enjoyable way that they will remember. Kidsafe was founded in 19...


Hospital Chemical Storage Ventilation

Hospitals require a number of potentially hazardous chemicals in day to day maintenance, cleaning, sterilisation, testing and operating applications. The health care sector represents one of the largest users of chemicals in the UK. The storage of these chemicals involves a number of considerations in terms of temperature, ignition control, ventilation and segregation. In this article, we focus on chemical storage ventilation. The ventilation of chemical storage areas is of paramount importance to ensure clean air and a safe environment for ...


The Importance of Shipping Warehouse Ventilation

According to energy advisors, warehouses spend on average 15% of their budget on energy bills every year. Mechanical ventilation can contribute to a high percentage of this spend. In this article, we explore the importance of effective warehouse ventilation. Like many hazards, poor ventilation poses a risk to employee health, machines and equipment as well as goods and products. To avoid negative impacts on businesses ventilation hazards must be eliminated. These include a reduction in productivity, a decreased yield, machines or equipment m...


Corrosive Fume Extraction in the Water Treatment Process

To provide water that is safe for human consumption, there are a number of processes that the water treatment industry use. Coagulation and flocculation are often the first steps in water treatment. Chemicals with a positive charge are added to the water. The positive charge of these chemicals neutralises the negative charge of dirt and other dissolved particles in the water. When this occurs, the particles bind with the chemicals and form larger particles, called floc. To separate the floc from the water, it is allowed to settle and fal...


Industrial Fans for Offshore Hazardous Areas

Given the corrosive and potentially hazardous nature of the environment, a number of variables need to be considered when selecting equipment and components for offshore applications. Fans within ventilation systems are no exception and can be found in various areas of an offshore platform, for example, compressor cooling enclosures, production platforms or gas turbine enclosures. These areas present varying degrees of hazard which the offshore fans must be suitable for. Two important variables for consideration include the need for ATEX (n...
