EC fan exceeds 2015 ErP regs
changes to min- imum efficiency regulation rates of ErP 327/2011 –2015 indicate that commercial fans in the EU market- place will soon require a much higher minimum efficiency if the input power is between 125 Watts and 500 kilowatts. In response to the changes, Airflow is one com- pany which has launched a range of compact high efficiency driven EC commercial fans that use up to 80 per cent less energy than their AC fan predecessors. Airflow says its new low energy EC Single Inlet fans achieve volume airflow from 83 l/s to 115 l/s, and have significant pressure development on the largest model. High FMEG levels are said to ensure they are compliant with updated regulations. Constructed from mild steel with a robust coating to finish, each fan casing is fitted with an outlet flange, incor- porating fixing holes for ease of installation. Airflow’s larger offering of Double Inlet high efficiency EC fans are also said to be engineered for significant benefits in perform- ance and pressure, and are specif- ically designed for applications where low noise levels and/or
space is an issue. The company says the new range achieves from 165 l/s to an impressive 1,200 l/s and over 700 Pascals.
Both Single Inlet and Double
Inlet offer a good range of control via 0-10V input, due to the high efficiency EC motor, and have a tachometer reading via 0-10v out- put and also feature up to IP24 ingress protection. An auto shut- off and reset function for over/ under voltage and temperature on the EC Double Inlet Fans is also a standard feature.
These fans have been designed with the dimensions and perform- ances of some of Airflow’s older double inlet range that will become non compliant in terms of efficiency in 2015 in mind, and will also offer a high efficiency EC fan for any new commercial HVAC application.
Bob Sharples, commercial product manager at Airflow Developments says: “In wake of recent changes to energy efficient regulations, here at Airflow we strive to supply to demand, and our extensive range of compliant EC Fans are a first to the EU fan market based on dimension and unique performances.”
Indoor air quality matters
BEAMA – the electro technical industry body for the UK and Europe has launched the ‘Indoor Air Revolution Campaign’, to help raise consumer and industry awareness of the importance of adequate ventilation. To mark the launch of the ‘Indoor Air Revolution Campaign’ BEAMA is calling on all construction industry professionals involved with refur- bishment and building services specification to ensure they are aware of the consequences of inadequate ventilation. To get up to date on the guidance around ventilation see the BEAMA Green Deal Ventilation Guide here:
