Howo Vacuum Jetting Truck
HOWO vacuum jetting truck is a specialized sanitation vehicle that integrates high-pressure cleaning and vacuum suction functions. It is mainly used for dredging and cleaning urban pipe networks, septic tanks, and sewers. Its core function is to powerfully wash pipes, roads, septic tanks, and other areas with a high-pressure water gun, while simultaneously using a vacuum suction system to quickly suck sewage, sludge, and debris into the onboard tank, achieving integrated "cleaning and suction " operation.
● The vacuum pump and high-pressure water pump are from well-known Chinese and international brands, suitable for various working environments. And equipped with a silent system for strong continuous operation capability.
● The hydraulic system supports optional front lifting and middle lifting for unloading.
● The rear cover features hydraulic opening and hydraulic locking, with stable operation, excellent synchronization and good sealing performance.
● The tank body is equipped with a low liquid level alarm system and an anti-overflow system.
Components of the HOWO combination vacuum jetter truck

1. Chassis: HOWO 4×2, 4×4, 6×4, 6×6, and 8×4 chassis are available, providing power and driving stability.
2. High-Pressure Cleaning System: Equipped with a high-pressure pump and rotating nozzles, the water flow forms a fan-shaped or rotating jet through the nozzles, penetrating blockages and removing attached dirt.
3. Vacuum System: Composed of a vacuum pump, anti-overflow valve, and suction pipe. The vacuum pump creates negative pressure inside the tank, and the suction pipe draws the waste into the tank, with a suction range of over 8 meters.
4. Tank: Made of high-quality carbon steel, with internal baffles to reduce liquid sloshing during transport. An exhaust valve on the top prevents overpressure, and a rear drain port supports gravity or pressurized discharge.
5. Control System: Real-time control of cleaning pressure, suction start/stop, and tank lifting; some models are equipped with remote control functionality to enhance safety.
