If your sweeping needs include dustless sweeping technology, then contact us about the specially designed TYMCO Model DST-6 and Model DST-4. These models both include regenerative air systems that have been equipped with fabric filters to sweep ultrafine material. These filters can capture a minimum of 95% of 0.30 micron and larger size particles. Industrial Disposal Supply is proud to offer these two ETV (Environmental Technology Verification) verified TYMCO models in our lineup of street sweepers.
