Energy Efficient Fan Filter Units (FFU’s)

  Optimising the performance of an FFU based system within cleanroom and containment applications offers significant energy saving opportunities. High efficiency EC technology lies at the centre of reducing energy consumption in fan filter units, even when systems vary due to airflow path and operating conditions. FFU manufacturers have risen to the challenge of reducing costs with the development of improved control and EC motor technology. A cleanroom can be up to 50 times more energy intensive than an office building because of th...


EC Plug Fans for Powder Control & Clean Room Applications

Ventilation & Energy Efficiency are the key areas to consider when designing a cleanroom for powder control. Clean rooms are vital when it comes to ensuring powdered medicines are contamination free during and after the manufacturing and packaging stages. Investing in new technology in addition to adopting hygienic handling techniques are paramount to effective clean rooms. Not forgetting air ducts and ventilation areas to facilitate the airflow and pressure required to ensure the required number of air changes per house and pressurisation ...


Reducing Fan Energy Consumption in Fume Cupboards

The already impressive range of corrosive fume fans from Axair Fans has now been extended to include an energy efficient range featuring B34 type IE5 EC motors located outside of the airstream. As the market demands more energy efficient systems, the introduction of the EC range of fans allows fume cupboard manufacturers to reduce their fan energy consumption by up to 20% without affecting performance, ultimately enhancing the energy efficiency of the entire fume extraction system. System designers are now keen to look at all options to redu...


Why Refurbish AHU Systems with EC Fans Over New AHU Installs

To Refurbish AHU or Not to Refurbish AHU Old buildings can often feature outdated and deteriorating ventilation systems. The first opinion may be to replace the entire air handling unit, but often to refurbish ahu system components can prove beneficial beyond financial gain. This week we look at the advantages to Refurbish AHU Systems over replacing the entire air handling unit itself. One major problem in favour of refurbishment is that of the existing air handling unit system. Ductwork and max air volume delivery are often governed by...


High Performance Cooling for High Power Control Panels

Over the past few years, it’s quite clear that components within high power control panels have got smaller, this is down to the challenges imposed by clients wanting smaller enclosures to fit within much smaller spaces. With often huge amounts of terminals, wiring, circuit breakers, RCBO’s and much more general electrical components packed tightly into panel trunking up against core high power components such as variable frequency drives, motor starters and programmable logic controllers, quarters can be crowded resulting in an increased a...


Reducing Ethylene to Slow Down The Food Maturation Process

Reducing ethylene to slow down the food maturation process of fresh produce is key to cutting down the amount of food waste in the retail and hospitality sectors working with fresh produce. Axair have a range of hydroxyl radical technology that reduces the production of ethylene and one company in particular to trial this technology is Freshview Foods Ltd, situated just opposite our premises in Wolstanton. If you’ve ever visited Axair Fans before, you’ll know that we’re located on an industrial estate with a wide range of neighbouring ...

Has it made you rethink about airborne viruses and other potential harmful and unclean air? Let's take a look at how businesses are reducing stress levels with clean air solutions during the pandemic.    Did you know that over 65% of people have suffered with severe stress since COVID-19 restrictions and with 43% claiming to be more depressed than usual and feel alienated in the workplace? Chronic Stress weakens the im...


ECFanGrid Cooling Power Delivered to Rolling Stock Yard

We have recently provided a rolling stock maintenance yard with two ECFanGrids as part of a package of works to improve the working environment. Following on site testing, we delivered the ECFanGrid solution within 3 weeks of receiving the order. The problems the facility faced, and our answers to those issues, are explained below. The Problems The temperature within the main workshop at the maintenance yard was too high. This was due to a combination of heat generated from hot works and day-to-day operations coupled with insufficient ventila...


Transformer Cooling Fans

Transformers work to either ‘step up’ or ‘step down’ an incoming power supply. This is done by a precise relationship between the number of turns on the primary and secondary coils. Put simply, a transformer converts energy at one voltage level to energy at another voltage level. Transformers do not have any moving parts but they do suffer losses, these are called either ‘copper losses’ or ‘iron losses’. Copper loss is the electrical power lost in heat as a result of circulating the currents around the transformers copper win...


The Importance of Chemical Storage Ventilation

Many industries require a number of potentially hazardous chemicals in day to day maintenance, manufacturing, cleaning, sterilisation, testing and operating applications. The safe storage of these chemicals involves a number of considerations in terms of temperature, ignition control, ventilation and segregation. We discuss the needs of chemical storage ventilation below. The ventilation of chemical storage areas is of paramount importance to ensure clean air and a safe working factory environment. Ventilation is needed for chemicals and the...


Wastewater Treatment Ventilation: Polypropylene vs. Stainless Steel and GRP

Environmental wastewater treatment plants face a number of challenges in terms of ensuring safe and effective ventilation. Water treatment processes must control hazardous substances, chemicals and gases such as methane, ammonia, phosphorous, pesticides and carbon dioxide. Consequently, wastewater treatment plants are, by their nature, one of the harshest engineering environments. Why is Ventilation Necessary? Ventilation is necessary in providing a safe clean air environment for employees working on site. Water treatment ventilation works by...

Avoiding Corrosion in HVAC & Protecting Employee Health

When installing a HVAC system, the main aim is usually to heat or cool the environment for employee comfort. Often underestimated is the impact that HVAC systems can have on employee health. Corrosion, caused by the presence of chemicals, is one of the biggest threats to HVAC systems and indicates an unsafe environment for employees. Corrosion damage and its consequences in HVAC systems are discussed below. What is Corrosion Damage? Corrosion mainly occurs in metals when they react with their environments; their refined form turns into stable...


Renewable Energy: Fans for Wind Turbines

The UK's offshore wind power capacity is set to nearly double by 2030, as a result of a new government initiative. Offshore wind has become an increasingly affordable source of clean energy due to plummeting costs. This, coupled with an increasing environmental awareness in consumers, is reinvigorating the focus on wind as a source of inexpensive, renewable energy. Wind turbines require fans to ventilate and cool several different areas to maintain and preserve the functioning of its equipment. These areas include the nacelle, generator, tra...
