Announcing Filter Enhancements to the SubDrive Connect Platform

12/04/2023 | Products, Update

Franklin Electric’s SubDrive Connect variable frequency drives (VFDs) are built to help you save time and costs when installing and servicing submersible and above-ground jobs for up to five horsepower. Now we’re enhancing the experience with a filter update designed to boost performance in residential applications.



Why is Electrical Filtering Needed in Residential Applications?

The LED lighting and dimmer switches used in today's homes can be sensitive to the signals emitted by active electronic devices, including VFDs. We’re addressing these disruptions with new Type 3R Indoor/Outdoor rated input filters that prevent signal interference. Now available as an accessory add-on, these filters are designed and tested for use with SubDrive Connect and can be installed on the input side of the unit. Order based on your horsepower needs:


Filter Item #

Horsepower Rating

For Use With


3HP / 23A

Up to SubDrive30


5HP / 36A

Up to SubDrive50


Please note that these new filters have been optimized to work effectively with SubDrive Connect models. The electrical ratings of these filters cover SubDrive Utility applications; however, additional troubleshooting and/or filter accessories may be required to completely mitigate interference issues with SubDrive Utility installations.

Franklin Electric offers support to help you determine when these filters should be used. For application-specific questions, please contact your local Franklin Electric Sales Representative or Technical Support at 1-800-348-2420.
