Don & Low case study

Manufacturers of woven and non-woven polyolefin technical textiles.

Key objectives

  • Cleaner Air Circulation
  • Energy Efficiency
  • No increase in operational noise levels


Don & Low asked us to help them find a solution to create a cleaner air environment for their production employees. The production area houses a newly installed manufacturing machine that produces melt-blown non-woven textiles. Due to the process, the machine emits heat and smoke which contaminates the air and makes for an uncomfortable environment for employees.


We analysed the area to establish the best product for the challenge and identified that to ensure all objectives were met, the Eco-power hybrid roof ventilation unit, incorporating true hybrid technology offered the best solution. Hybrid ventilation is defined as a "two mode" (or multi-mode) system that is controlled to minimise energy consumption, whilst maintaining acceptable indoor air quality and thermal comfort. It will work to ensure a constant supply of fresh air and combines natural ventilation, with a high efficiency electronically commutated (EC) motor in a single unit to ensure reliable and on-demand peak performance. EcoPower is capable of operating unhindered in natural wind mode, or in both natural and energy efficient mechanical modes simultaneously. When required, performance is boosted by activating mechanical operation to ensure desired airflow rates are achieved. Even during mechanical operation, wind mode can improve flow rate performance.


"Eco-Power from CPA’ has exceeded expectations in air change in the department and ensures a clean air environment for employees. We trusted the team at CPA to deliver on our objectives and we are completely satisfied that we have a system for the future".
