Fans and blowers

Fans can compress and/or mix the fluid that they are supposed to be moving. Mixing and over-compression are signs of inefficient fan use. Unlike pumps however, fans may not alert you if they are running inefficiently because they usually operate quietly in most regions of their curve while drawing more power than necessary. This results in energy waste, poor system performance, and may cause premature failure of components.

We provide assistance in the analysis of fan and blower systems through scoping studies:

  • Scoping studies – A study that measures the performance and power consumption of a fan or blower system. This provides an operational benchmark and identifies opportunities for energy savings and performance improvements. Instrumentation is placed on the customer’s system to monitor the operating characteristics. The resulting data forms the baseline energy consumption and operating parameters of the system, and identifies energy savings and performance improvement opportunities.

A scoping study usually leads to a feasibility study which accurately details the project options, capital costs, energy savings, operational and reliability improvements, and also calculates the Performance Optimization Program incentive that reduces the capital cost of a project.


The benefits of reviewing a fan or blower system may include:

  • reduced energy cost;
  • increased system performance, reliability and efficiency;
  • reduced maintenance and downtime;
  • incentives to reduce the capital cost of a project and accelerate payback.
