OPERATING INSTRUCTIONS
Dif-Pur equipment works with high efficiency, very low consumption rear-blade jet motor-fans thanks to their
EC motor. The motor is 100% voltage adjustable external rotor. The set is statically and dynamically
balanced up to Q-2.5.
These motors are mounted on shock absorbers to prevent vibration transmission and reduce sound
emissions.
These equipments are prepared to work as easily installable filtration units, as it has stops to fit the filters and
prevent their movement.
Controllers characteristics
•
ON/OFF:
They have a switch that cuts off the fan power and automatically stops the equipment.
•
Control 0-100%:
They include a potentiometer 0-10V that allows to regulate the fan speed from 0 to
100%.
•
Constant flow rate:
When selecting a working point, the equipment regulation controls the fan to
maintain the flow rate, even if the working pressure goes up when the filters get dirty. This feature
stops working if the filters are too dirty or if 100% fan flow is requested.
•
Visual filter alarm indicator:
Using a LED indicator, the user is informed that the filters are dirty and
require a replacement to maintain the level of cleaning.
