Pneumofore defines the term "efficiency" as the ratio of total energy input to performance delivered. Quantified in number, this is measured in m3/h for each kW or cfm for each hp. And we mean by that 'all over' power consumption, not 'shaft power' only. In the case of a rotary vane air compressor, for example, the performance of the rotary vane cylinder is central to the efficiency of the process. Pneumofore's superior results stem from over 80 years of research and engineering dedicated to perfecting the compression cycle. This includes such innovations as the patented method of intensive oil injection, which can save up to 15% energy.

Electricity is consumed, however, not only by the motor that powers the compressor but also by the oil circulation motor, the cooling fan motor, the control panel, and other more minor components. Addressing design and layout factors such as cooling, ventilation, vibration, noise levels, access to parts, ease of installation, etc. can contribute substantially to the overall efficiency of the unit. Most Pneumofore models reduce energy consumption by 20-25%, which is especially interesting given the high longevity of these units.
