2026 Tymco DST-4® Dustless Diesel / Cabover

2026 Tymco DST-4® Dustless Diesel / Cabover

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 uses filters that 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, far exceeding PM10 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 avoid puddles and leave debris behind. Our DST System when coupled with our Regenerative Air System produces the most technologically advanced street sweeper available today. Both our DST-4 and DST-6 set the performance standards for particulate matter removal in the U.S. and Canada.

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 industrial and municipal applications.

TYMCO Sweepers are designed in way that truly reflects the culture at TYMCO. When our engineers approach a challenge or a need on the sweeper, they work to develop straightforward solutions. For example, all TYMCO Sweepers use True Regenerative Air. This design delivers the simplest approach as well as the highest performance with the lowest downtime as compared to other sweeper technologies.

• True Regenerative Air

• Easy Access to Components

• High Productivity

• Smart Gutter Broom

• Operator Friendly Design

• Low Maintenance

Features may include:

• The TYMCO Model DST-4 Pick-up head incorporates a full-width 78 inches of blast and suction. The Model DST-4 heavy duty Pick-Up Head is designed to work effortlessly with the TYMCO Regenerative Air System to pick up a wide variety of debris from leaves and trash to heavy dirt, sand, rocks, and most importantly, ultra-fine particles.

• High dump function that lifts the hopper up to 72 inches for dumping into various size containers and most 30 cubic yard roll off containers. The TYMCO Model DST-4 is equipped with powerful piggyback hopper lift cylinders. These heavy duty dump cylinders allow the Model DST-4 to high dump even the heaviest of loads. A safety strut is permanently attached to the hopper frame for easy accessibility. When the hopper is in the up position, simply insert the steel pin into the hole on the built-in safety strut.

• Gets debris out of the curb/gutter with 36" diameter gutter brooms with in-cab controls. The tilt gutter broom allows you to reach down into the deepest gutters. TYMCO's 36" gutter broom design has a pressure sensing sequence valve to automatically determine the digging pressure needed for different debris; therefore, customers get maximum broom bristle life and cleaning performance.

• From inside the cab, the operator can control the speed of the gutter brooms. This allows the operator to match the speed of the truck while sweeping to lessen the amount of dust being kicked up.

• TYMCO incorporates a high efficiency multi-pass cylindrical centrifugal dust separator for maximum particulate separation and sweeping performance. Designed for easy clean out and maintenance.

• On board 77 gallons of water for dust control around the gutter brooms and inside the hopper. For below freezing conditions, the sweeper will continue sweeping dustless without using water.
