The TDM-M04 40m spray cannon is designed for dust suppression projects that need a longer working distance than a small close-range fog cannon, while still requiring compact equipment and flexible operation. It is suitable for construction sites, quarries, demolition areas, material loading points, temporary stockpiles, site roads and outdoor industrial dust control areas.

For many small and medium projects, a 30m spray distance may not fully cover the working area, especially when the dust source is located around a wider site entrance, a material transfer point, a quarry working face or an open storage area. In these conditions, the 40m spray cannon provides a practical mid-range option. It offers more spray coverage than a 30m fog cannon model without moving directly to a larger long-range machine such as 80m, 100m or 120m.

This 40m fog cannon uses a water mist spraying system to help capture airborne dust and reduce dust spread around the working area. The fine mist can be directed toward dust sources such as vehicle movement, material loading, stone crushing, earthwork, demolition work or open material piles. For outdoor sites where dust changes with wind direction, working position and material handling activity, the 40m spray range gives operators more flexibility during daily dust control work.

The TDM-M04 model is a suitable choice for contractors, mining service companies, construction companies, material yard operators and industrial plants that need reliable dust suppression equipment for regular site use. It can be used as a single dust control unit for a defined working area, or as part of a larger dust suppression plan when several dust sources need to be controlled across the site.

Compared with large long-range fog cannon machines, the 40m spray cannon is easier to arrange in limited site space and is more suitable for projects where the dust source is not extremely far away. It is often selected for medium-distance spraying tasks, such as construction road dust control, quarry loading areas, demolition boundaries, material transfer zones and small outdoor stockyards.

Before selecting a model, several site conditions should be checked, including the dust source, working distance, site size, water supply, power supply, installation position and local environmental requirements. If the working distance is shorter, a 30m spray cannon may be enough. If the site is larger or the dust source is far from the machine, Huali can also recommend 60m fog cannon, 80m fog cannon, 100m fog cannon or 120m spray cannon options.

For an accurate quotation, please send us your application, dust source, required spray distance, site size, water supply condition, power supply and destination country. Huali will help confirm whether the TDM-M04 40m spray cannon is suitable for your dust suppression project and provide a practical configuration suggestion based on your site conditions. Contact Steven on WhatsApp
