Reduce Energy Consumption in Laboratories With EC Fume Fans

25 October 2024

With so much uncertainty on future energy costs, it is a matter of urgency for management and technical specialists to reduce costs where possible across laboratory facilities.

Significant rise in the cost of energy within the last few years has caused a huge strain on educational establishments, with many schools, colleges and universities facing a shocking 50% increase in energy bills.

Educational laboratories are one of the largest energy consuming sectors in the UK, consuming between four to six times more energy per square metre than standard offices or commercial buildings. This is predominantly down to the energy intensive ventilation systems necessary to ensure a safe environment whilst maintaining the required airflow and temperature for effective processes. Reducing energy consumption in laboratories is a significant method of reducing overall energy use. System designers face increasing pressure to ensure maximum efficiency, cost effectiveness, and reduced environmental impact. They have a duty of care to ensure the safety of the people using the equipment and, in the building, this must not be compromised when reducing costs and managing strict budgets.

Now is a good time for system designers to look at all options to reduce energy consumption within laboratories. Reducing the amount of energy used in any mechanical ventilation system, and the most energy hungry component, the fan itself, is a good starting point. Upgrading existing systems with energy efficient fans is a more cost-effective option than replacing a full system and will contribute towards meeting long term energy efficiency and cost reduction goals.

Where laboratories use a single or multiple fume cupboard, whether recirculating with a fan installed in the cupboard, or exhausted into atmosphere, efficiency should be a part of the selection process for the manufacturer of these units. This means balancing energy consumption with overall fan performance to ensure that the fume cupboard performs as expected in all conditions. The impressive range of corrosive fume fans from Axair Fans includes an energy efficient range featuring B34 type IE5 EC motors located outside of the airstream.

As the market demands more energy efficient systems, the EC range of chemical resistant exhaust 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.

EC Corrosion Resistant Fans & Motors        
Complementing the existing range of chemical fans, including the ATEX plastic extract range from Axair, the IP55 polypropylene collection of EC fans and motors are available in variety of sizes in both single and three phase variants covering airflows from 20-9000m3/hr and pressures to 1500Pa.

Single phase EC motors come equipped with integrated drive and IP55 protection against dust and ingress. An outdoor weatherproof cowl can be supplied for additional ingress protection if required.

Three phase EC IP55 motors are supplied with a supporting IP66 inverter drive for accurate speed control of the fan motor to match the exact ventilation needs of the application. Controlling the speed of the motor further allows for energy saving by limiting the amount of energy needed to power it. As an example, slowing a fan motor by 20% saves nearly 50% in energy consumption.
Energy efficiency in laboratory settings can make an enormous difference not only reducing costs but also with reducing the overall carbon footprint. The integration of EC chemical resistant exhaust fans within fume cupboards is a significantly simple step towards making this change.
