We Make it A White Christmas with Snow Business

Christmas adverts, retail window displays and seasonal films are always complemented by a layer of white, freshly laid snow. As many of you will know, this snow isn’t real, and artificial snow and effects are big business. As the saying goes….there’s no business like show business…. Or in this case Snow Business. Throughout the year we have and continue to work with the company that helps to add an essential Christmas ingredient to many of these ads and displays by quite literally, making it snow! Based in Stroud, Gloucestershire,...


Noise Optimised Units for Fan Coil Units

Vibration induced noise can be a major problem in fan coil installations. It originates within the motorised impeller unit and cannot be entirely eliminated until new technology invents an induction motor that is free of electromagnetic vibration and an impeller that is perfectly balanced.] Ecofit believe they have gone a long way towards solving the problem by introducing double inlet centrifugal fans that incorporate anti-vibration mountings between the fixed shaft and the scroll mounting arms. The fans, prefixed ‘GDS’, therefore achie...


Effective Redundancy by Running Fans in Parallel

The air handling unit market is under constant pressure from all sides; pressure from the end user to improve indoor air quality, pressure from architects to provide more comfort and to produce more aesthetically pleasing units but also from energy consultants who demand manufacturers to deliver energy efficient units with higher airflow performance and pressures at lower installation and operating costs. Commercial heating and ventilating represent a major proportion of any construction budget, frequently comprising ten percent or more of t...


Fume Cupboards & Alarms

Axair’s Labair controls range has been created for applications involving hazardous fume extraction such as fume cupboards and chemical cabinets. There are two models available A and C, both of which are available in a standard version or Digital. Both the A and C series are white with 3 push buttons: fan on/off, light on/off and alarm mute. They also feature a green LED light that illuminates to signify that the airflow is OK, a red LED light that flashes to alert that the air speed is too low and a sash high LED which starts flashing whe...


Industrial Fans for Offshore Platforms

Offshore oil and gas platforms incorporate a wide range of fan applications from production areas, power generation and compressor cooling. Offshore sites are built to withstand the harsh and corrosive environments in which they’re situated, and therefore components within systems must be suitable for purpose. Where hazardous gases are present, ATEX variants are required and should be specified by the system manufacturer’s maintenance manuals to advise the zone that the components should be certified to. Corrosion resistant fans that are op...


Understanding Electromagnetic Compatibility

EMC (Electromagnetic Compatibility) testing exists to ensure that your electronic or electrical devices do not emit a large amount of electromagnetic interference (known as radiated and conducted emissions) and that your device continues to function as intended in the presence of several electromagnetic phenomena. Regulatory bodies around the world have placed limits on the levels of emissions that electronic and electrical products can generate. Also, electromagnetic immunity testing is mandated for some areas and some product types. EMC m...


Axair Continue to Support the Midlands Air Ambulance Charity

The Midlands Air Ambulance Charity continues to save lives across the communities of Gloucestershire, Herefordshire, Shropshire, Staffordshire, Worcestershire and the West Midlands, flying seven days a week, 365 days a year. Midlands Air Ambulance Charity has grown in strength from just one helicopter flying out of a temporary airbase in 1991 to three helicopters currently serving a population of over 6 million people. Each of the three air ambulance aircraft is called out on a mission on average three times a day. The Charity can proudly...


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 ...
