1. Powerful Vacuum Suction System
Equipped with a high-performance vacuum pump that generates strong negative pressure to efficiently extract sewage, sludge, wastewater, and other liquid or semi-solid waste from septic tanks, sewer lines, drains, and other catchment points.
2. Large Sealed Tank Body
The truck features a large-capacity sealed tank designed to securely hold collected waste without leakage, odor escape, or contamination during transport — ensuring cleaner and safer sanitation operations.
3. Robust HOWO NX Chassis
Built on the durable HOWO NX truck platform, the vehicle delivers reliable driving performance and stability with a strong chassis and suitable engine power tailored to sewage suction applications.
4. Efficient Suction & Discharge Workflow
Designed for fast and continuous operation, many models undergo optimized piping and valve configurations that allow fast suction, easy unloading, and smooth control throughout the work cycle.
5. Hydraulic Control Integration
Integrated hydraulic systems enable controlled operation of the tank, rear door, and accessories, simplifying daily use and reducing operator effort.
