Dilution & Local Exhaust Ventilation for Shipyards

One of the major hazards associated with working in maintenance shipyards is the impact of poor air quality. Those working in confined spaces may be subject to stagnant air as a result of insufficient airflow or toxic and hazardous contaminants as a result of source pollutants. Ventilation is required to ensure the correct level of oxygen needed to dilute and remove contaminants such as CO2 and hydrogen sulphide, in addition to comfort cooling or heating. In general, there are two common methods of shipyard ventilation; Dilution Ventilation ...


Industrial Fans for Ballast Water Treatment Systems

Finally coming into force on 8th September 2017, the International Convention for the control and management of ships’ ballast water and sediments, places an emphasis on involved parties such as ship owners and manufacturers to give full provisions to minimise, prevent and ultimately eliminate the transfer of harmful aquatic organisms and pathogens through the control of the ships ballast water. The spread of invasive aquatic specifies into the sea can cause havoc for local ecosystems, affects biodiversity and leads to economic loss. The conv...


Understanding ATEX EEx Definitions

An explosive atmosphere can be one in the form of gases, vapours, mists or dusts, which can ignite under certain operating conditions. Potentially explosive atmospheres are found in many areas of industry, from mines and the chemical, oil and gas, and pharmaceuticals industries, to plants handling cereal, animal feed, paper, wood and coal. All these have the potential to produce gas, dust or fumes which can be ignited by a spark or flame. The classification of the potentially explosive atmosphere depends on the frequency with which potentially ...


Better Fan Efficiency – The New Ecofit V8 Motor

Axair Fans are excited to introduce the latest addition to our EC Technology product range. The high power EC motor known in the industry as the “V8 motor” is a new external rotor motor with input power up to 300Watts manufactured by our innovative and reputable supplier partner Ecofit. For our existing customers, the V8 motor replaces the L4 motor, with the advantage of higher power at a lower speed enabling a better overall efficiency. Previously the external rotor motor collection consisted of the G9 with input power to 150Watts, and L4 ...


We Are A Carbon Zero Company

  Being green has never been more crucial. With companies in the UK taking more responsibility for the environment and making better decisions to benefit the world’s future, being a carbon zero company is becoming the norm in the United Kingdom. Here at Axair we are no exception. Like many companies in the UK we have achieved our carbon zero status by offsetting our carbon emissions, we do this by working in partnership with carbon management company, CO2 Balance. At the Axair Group we are proud to announce that we have been a carbon ...


Carbon Refrigerants & Flammable Gases In Commercial Refrigeration

Carbon (CO2) refrigerants are changing the world of refrigeration as we know it, gradually replacing current Hydrofluorocarbon (HFC) and Hydrocarbon (HC) refrigerants in the market. HFC and HC refrigerants are currently the most commonly used refrigerants in refrigeration units. HFC refrigerants contain Hydrogen, Florine and Carbon. Although HFC refrigerants have no ozone depletion potential, it does however act as a greenhouse gas with an average Global Warming Potential (GWP) of 2000. As a result, responsible use and equipment inspecti...


EC VS AC

When it comes to EC VS AC there are pros and cons for both. EC technology has continued to increase in both awareness and popularity in the air movement market. The increase in popularity was evident from this year’s ISH HVAC tradeshow in Frankfurt where a significant number of exhibitors had EC fans and for most of them their EC fans took centre stage. For those who are still unsure, EC stands for electronically commutated and combines voltages of both AC and DC bringing the best of both technologies together to form EC. This means th...


Axair Work with Kid Safe & Staffordshire Schools

Axair is proud to once again support the road safety initiative for Staffordshire Schools in partnership with Kid safe. Last year the use of educational games teaching road safety awareness, stranger danger, racism and bullying initiatives proved highly successful. With fewer road incidents in Staffordshire schools and an excellent engagement level between teachers and pupils. The games feature thought provoking spaces throughout the path including choosing the safest place to cross, keeping clear of the road and kerb side in busy traffic...


Fans Used in Renewable Energy Source – Wind Power

The versatility and type of fans used within air movement projects is apparent when you look at our applications page from smoke ventilation, air handling units and chemical storage units, Industrial fans are used in a whole host of machines and processes to cool components or facilitate the effective running of equipment.  When looking at the components within the design and manufacture of the popular renewable energy source, wind turbines, industrial fans play an integral role. How Do Wind Turbines Operate? Wind turbines operate on a si...


Industrial Fans for Pharmaceutical Isolators

In biological cabinets, the need to protect personnel and the environment from exposure to biohazards and cross contamination during routine procedures is of the utmost importance. Many isolators are used within pharmaceutical manufacturing processes including negative pressure and positive pressure units. Types of Pharmaceutical Isolators Negative pressure pharmaceutical isolators are separative devices used for the safe handling of toxic drugs and to retain other process generated particles, the isolator provides a full barrier protect...
