These cutting-edge filtrations products were designed and developed in conjunction with Otis and Schindler elevator companies. They eliminate carbon dust in elevator machine rooms cause by brush wear.



In 2001 founder Scott Sanders reformed a Sanders, Inc., to develop and provide unique filtration products for the vertical transportation industry. UTC/Otis asked us to develop a filter to eliminate myriad problems associated with excess carbon dust from generator brush wear in elevator machine rooms. Carbon dust from brush wear created steep costs for elevator service companies, which lost considerable revenue because of unnecessary housekeeping, customer complaints and system failure. True to form, we welcome the challenge and responded by designing a filter that offered almost no restriction or increase in temperature in the generator, even with the filter fully loaded. Additionally, we developed a simple-to-use “DeCarbonator” blowout bag for the removal of all accumulated carbon dust within the generator. Another problem presented; another problem solved.

We are an Original Equipment Manufacturer (OEM) for UTC/Otis Elevators and have been for more than 19 years. For the past 15 years, we have been ThyssenKrupp “TKE Preferred Vendor.” We offer a complete line of 157 custom filters for the elimination of carbon dust created by brush wear in AC/DC generators, illustrating our uncommon ability to solve specific filtration issues. We are specified or recommended by virtually every elevator manufacturer and electric brush company out there. After manufacturing and installing thousands of motor generator filters, we’ve not had a single failure in the field, compelling evidence of the attention to detail we put into our quality products, and something we embrace with tremendous pride.
