MD310T2.2B-INT can be considered when workshop extraction airflow needs to follow process demand. Its 2.2 kW motor class and 5.1 A output are the basic electrical selection figures. The effect of changing speed depends on the fan curve and duct resistance, so no fixed energy-saving percentage follows from the drive specification.
Technical specifications

| Overload | 150% / 60 s; 180% / 2 s |
| Braking unit | Built in; resistor selected separately |
| Protection | IP20 |
Current is rated at 6 kHz carrier frequency. Derating applies above 40 °C. Confirm enclosure depth and clearances from the exact-code drawing.
Application selection
Establish required extraction flow and minimum motor speed. A dusty workshop needs suitable enclosure protection and cooling for the IP20 drive.
Can the unit be mounted openly in a dusty workshop?
An IP20 enclosure is not sufficient for open mounting in that environment. Panel protection, filtration and thermal design need application-specific selection.
Installation and commissioning
Qualified personnel must use the exact-model manual for installation and commissioning. Apply lockout before physical inspection, retain project/parameter backups and never bypass protective functions.
Quotation and supply
Send the fan nameplate and target extraction flow for a combined drive and enclosure assessment.
Price, stock and lead time are not verified and require confirmation in the quotation.
