Dustless Sweeping Technology

The concept of dustless sweeping began in 1984 at TYMCO. TYMCO was asked by a customer if we could modify our Regenerative Air System to be able to sweep ultrafine material without the use of water for dust control in order to pick up lead dust.

For this customer, it was very important that the sweeper not only removes the lead dust from the paved surface but also contain the dust due to the toxicity of lead in higher concentrations.

TYMCO answered the call to assist this customer by integrating fabric filters into the Regenerative Air System in order to assist in capturing the ultrafine material. Dustless Sweeping Technology was born at TYMCO to try to help this customer with their need. As the years have gone by, the many different types of customer needs continue to help update and improve Dustless Sweeping Technology, which is reflective in the latest Model DST-6® and Model DST-4®.

The filters used in the Model DST-6 and Model DST-4 have been determined through independent laboratory testing using the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) 52.2 testing standards to have a Minimum Efficiency Reporting Value (MERV) 16 Rating, meaning they are able to capture a minimum of 95% of 0.30 micron and larger size particles.

The TYMCO Model DST-6 and Model DST-4 are street sweepers that can sweep in the harsh conditions of freezing weather and anti-skid material removal without the use of water as dust control, as well as provide year-round dust removal from sweeping surfaces, which reduces PM10 and PM2.5 (particulate matter) from the air, and have been verified by Environmental Technology Verification (ETV) Canada to pick up about 90% of test material with a mean diameter of 3 µm (microns or micrometers) without the use of water for dust control.

The DST-6 and DST-4 are also industrial sweepers that do an excellent job of removing and containing dusty materials that contribute to poor aesthetics, air quality and stormwater runoff quality. TYMCO Dustless Sweepers help address environmental challenges that are created by the need to comply with regulations and to be good neighbors and corporate citizens.
