Can I use a voltage speed control to change fan speed?
Answer: No, you will damage the motor over time and void the warranty. Use a frequency inverter with a three phase motor. Single phase motors are not compatible with inverter.
What is the maximum operating temperature of your PP fans?
Answer: about 80°C but this can change depending on conditions such as rpm
What information should I supply at the time of placing a fan order?
Answer: We need to know: fan model type and/or reference number, rpm, discharge position, voltage/phase, airflow/pressure requirement and accessories (Example: 2 units SEAT 25, ref# 51252000, 1400rpm, LG90, 230V, three phase, 1000m3/h @ 380Pa with metal stand)
Do you systematically supply each fan with a stand?
