Sound & Noise Within Industrial Fan Systems

In the world of HVAC the efficiency of industrial fan systems is often compromised by an ineffectively designed air movement system and poor efficiency. This is often accompanied by unwanted fan or air velocity noise making the whole system less than desirable. The annual UK industrial fan power consumption is estimated at well over 30TW-hours. If best practice was applied within the UK, CO2 emissions alone could be reduced by around 2 million tonnes per annum and electrical costs would also be reduced by a similarly shocking amount. Effici...


Axair Fuel Fans For Efficient, Clean & Safe Biofuel Drying

With renewable energy sources on our mind, we recently posted a blog update around Biomass as an alternative to fossil fuels so now we’re delighted to be able to add another renewable energy biofuel source provider to our midst, improving our expertise and improving the carbon footprint of UK businesses. From our previous post here, you’ll be aware that Biomass technology is safe, clean, reliable and sustainable, and as an example, a company spending £15,000 on heating can save up to 70% on heating and 50% on fuel costs. With such signi...


AHU Refurb | As Easy As Childs Play

The refurbishment of existing air handling equipment is a practical alternative to replacing with a whole new system, benefiting from cost effectiveness, less disruption, more flexibility and the ability to improve existing specifications. During any AHU refurb all fan types can be replaced with the latest energy efficient fans with either the option of EC motor with on-board controls or traditional fan motor and inverter combinations. For example replacing old forward curved fans with backward curved plug fans can reduce energy consumption...


We’re Going Big On Industrial Fume Extraction

We recently announced the arrival at Axair HQ of the largest plastic fan we supply taken from the SEAT collection of corrosion resistant polypropylene fans.

Axair Fans offer a variety of centrifugal fans available in stainless steel or marine grade finishes such as C3, C4 and C5M which describes the types of paint and paint systems commonly used for corrosion protection of steel structures. Axair CMRG’s range of Medium pressure, backward curved centrifugal fans are entirely made of hot galvanised steel providing a robust, corrosive resistant construction, available with...


Enclosure Ventilation – An Axair Guide to Power Electronics Cooling

Fan filter kits have been in use for around 20 years and are now considered ‘part of the scenery’ and a commodity product. Their function has not changed, they are still as useful as ever; however,  if the wrong product is selected, the whole control cabinet may overheat and compromise not only the value of the equipment it contains but also the panel’s primary function, powering a whole process plant, shopping centre or datacentre, for example. The impact of this could be catastrophic so it pays to seek advice and assistance when select...


Cabinet Cooling Project Proves Axair Knowledge is Power

Bespoke solutions don’t always have to involve bespoke products. Sometimes, the best solution can be found by using standard products but applying them in an unconventional manner.  Axair regularly fulfil customer requirements in this way; a recent example being a project we supported for a well-known control systems company with some very specific enclosure cooling requirements. The enclosure in question was generating 11 kW of heat; they were attempting to dissipate the British Standard, BS60439, which specifies that the temperature out...
