Test protocol

All Fieni sprayer units are tested in real-world work conditions: you can't reliably measure performances using just a test bench. We do things differently, our test protocol dictates that air speed measurements are performed on an operational unit, at different position and fan blades angle.

This enables us to factor in any airspeed loss due to mechanical obstacles within the unit and provide reliable performance measurements. At the same time we can measure the required operational power using dedicated instruments.
