The D3 sweeper is equipped with a 151 In³, 4-cylinder KOHLER engine, generating a maximum 74 Hp power and 300 Nm torque. ​

The machine is standard equipped with a Mann-Hummel engine filter that ensures a very high protection level on three incorporated levels:​

The mechanical suction-filtering collection system combines mechanical sweeping, suction and filtration to ensure high cleaning performance in urban areas. performance and great operational flexibility. The sweeper is designed to work effectively on different surfaces and in the presence of various types of materials, adapting to different urban cleaning needs.

The high sweeping speed, combined with a wide cleaning path, increases productivity and optimises working times. The increased surface area cleaned per pass also helps reduce the operating cost per kilometre of sweeping.

The low engine speed and reduced power requirement for suction help keep noise emissions low during operation. The technology makes it possible to operate at reduced noise levels, making it particularly suitable for night-time city cleaning operations.

The D-TEX filtration system uses special fabric filters designed to trap even the finest dust particles. The high filtering capacity completes the sweeping process, promoting the reintroduction of clean air into the environment and contributing to more effective dust management.

D-TEX
Standard Filter

The polyester fabric bag filter allows the machine to be used for long hours without clogging. While its filtering capacity of about 3 microns also allows the re-introduce only clean air into the environment.

D-TEX PRO
PES + Eptfe membrane

The ePTFE membrane guarantees filtration efficiency and suction capacity. By combining the ePTFE membrane with the polyester structure, the latter is more uniform and thus allows more homogeneous filtration of even PM10, PM5, PM2.5 and up to PM1 particles.
The membrane surface allows a greater release of dust, reduces the possibility of clogging and thus ensures a more constant suction flow.

D-TEX ULTRA
PTFE filter

The homogeneous structure of the filter, its light weight and the lack of polyester support guarantee:

• filtration efficiency

• suction capacity

• greater water resistance

Dust tends to detach from the walls more easily and thereby the suction flow always works at maximum performance even in rainy or very humid conditions.

The mechanical-suction-filtering system allows the D3 to work even without using water, drastically reducing consumption and promoting more environmentally friendly and waste-saving sweeping. Furthermore, waterless collection avoids increasing the weight of the waste as the collected material, free of liquids, is lighter when unloaded, helping to reduce management and transportation costs. The absence of water also limits the formation of scaling due to the mixing of waste and liquids, reducing maintenance requirements and facilitating cleaning operations of the machine.

The possibility of working with limited or no water usage reduces the need for frequent tank refills. This allows for a reduction in idle times related to filling operations and increases work continuity, improving the overall efficiency of the machine.

AST – Adaptive Sweeping Technology supports the operator during all work phases, automatically adapting the machine's operation to the sweeping conditions. The Easy Start functions, the ECO, NORMAL and BOOST operating modes and the STANDBY control simplify management of the sweeper, improving comfort, control and operating efficiency. Easy Start allows you to quickly activate the main work functions, while the three operating modes allow you to optimise the relationship between performance, consumption and productivity based on what the job needs. Finally, the STANDBY function allows you to temporarily interrupt the cleaning cycle and resume it later on while maintaining the previously set configuration.

The sweeping system is designed to ensure high collection performance and effective cleaning in various operating conditions. The standard configuration provides a cleaning width of up to 2,150 mm, while the integration of the third front brush allows you to expand the working width and increase the machine's productivity.

The third front brush increases the cleaning width and makes the sweeper more versatile for urban operations. The main functions are hydraulically controlled directly from the driver’s seat, via a control armrest with multifunction joystick, for precise and intuitive management of operations.

The third front brush allows the cleaning width to reach 3,200 mm. The wide operating range allows a greater surface area to be covered with each pass, reducing the time required to complete operations and optimising overall productivity.

The front brush can also be configured for weed removal. This solution allows the machine to efficiently work along edges, pavements and other urban areas affected by the presence of unwanted vegetation, expanding the possibilities of use of the sweeper.

The configuration is designed to ensure precise driving and high manoeuvrability in urban cleaning operations.

The machine's design facilitates access to the main components, simplifying inspection and routine maintenance operations. Inspection doors allow quick access to key areas of the sweeper, while brush removal is simple and requires a small amount of tools.

The transport washing system facilitates cleaning of the components and helps to enhance machine performance. The filter shaking system helps maintain filter efficiency, promoting constant filtration during sweeping operations.

The sweeper is also equipped as per standard with the Dulevo Telematic remote telemetry system, which supports the monitoring and management of the machine. Collecting information on the operation and use of the vehicle allows you to streamline maintenance interventions, reduce downtime and contribute to reducing operating costs, maintaining the high efficiency of the sweeper over time.
