The TYMCO Model DST-4, mid-sized, DUSTLESS sweeper utilizes the same state-of-the-art technology as TYMCO’s proven DST-6. The DST-4 removes dirt, dust and debris from the sweeping surface, and cleans the exhausted air to 99.999% of 0.5 Micron size particles, far exceeding PM 10 requirements. TYMCO’s patented filtration system enables the DST-4 to be equally efficient in wet or dry conditions, so you don’t have to add to the problems of meeting the EPA’s PM 10 requirements by avoiding puddles and leaving debris behind. Mounted on a highly maneuverable cabover “standard truck chassis,” the DST-4 can travel to the job site at legal speed limits and then perform the dustless cleaning required in both Industrial and Municipal applications. The DST-4’s low profile allows the sweeper to clean in those hard to reach areas. The DUSTLESS features are engineered to allow the sweeper to perform in all types of weather conditions with no operator adjustments required.
