Howo Dry Vacuum Truck
HOWO dry vacuum sewage truck is a highly efficient, safe and Eco-friendly specialized vehicle designed for the super suction and cleanup multiple type bulk materials. The Howo super sucker dry vacuum truck is designed and manufactured based on Sinotruk HOWO NX or TX series truck chassis, available for multiple drive model 4x2, 6x4, 8x4, etc. Matched with efficiently capacity 5tons to 50tons. All equipped with international top quality Roots Vacuum Pump, and stronger round shape vacuum tanker body assembly, which is an ideal truck for bulk material treatment. Below showing all side view of the Howo super sucker dry vacuum truck.
Howo high pressure slurry sand vacuum tank trucks are widely used for multiple industries, such as metallurgy, coal, mine, chemicals, energy, building materials, powder, and port logistics. It is designed for the collection, transfer and discharge over 100 different type powder and granular materials. Howo negative vacuum vehicles are capable of multiple function with iron-making, steel-making, sintering, coking, raw material processing, carbide furnace gas purification and dust removal, gas-fired lime kilns, smelting desiliconization and dephosphorization agents, coke breeze, aluminum powder, coal, mining powder, cement, lime powder, ash, etc.

I Roots Vacuum Pumps
Howo dry vacuum trucks are designed for bulk powder materials, and the heart of these trucks is the vacuum pump, which called Roots Vacuum Pump, also named as vacuum boosters dry-running pump. This type pump is based on a pair of 8-shape rotors, the lobe rotors that rotate synchronously at high speed in opposite directions, without agent of water or oil inside, but by the absence of internal compression, then can realize function of dry powder, sand, slurry, etc suction and discharge.

| Name | Roots Vacuum Pump |
| Model | Customized |
| Frequency | 60-80HZ |
| Pumping Speed | 5400-7000m3/h |
| Pressure Difference | 20-30mbar |
| Rated Power | 11.0/15.0 kw |
