Pneumatic Push Pull Vacuum Toilet System for Railway Passenger Coach

Push Pull Vacuum Toilet System for Railway Passenger Coach

1. Brief introduction:

Railway passenger car vacuum toilet adopts pneumatic push-pull vacuum system. It is designed in the principle Venturi of compressed air, the vacuum is generated from the transition tank, which collects the waste from the toilet. The waste is further squeezed into the waste tank at normal pressure, realizing fully enclosed and ordorless vacuum collection effect throughout the process.

2. Advantages & features of vacuum toilet system:

• Water-saving: The vacuum toilet consumes only 0.45 liters of water per flush.
• Odorless: Vacuum negative pressure isolates odors, eliminating odors in the toilet.
• Compact structure, small footprint, and easy maintenance.
• In the absence of electricity or air, the vacuum toilet blocks odors and aerosols from the waste tank and prevents them from entering the bathroom.
• The system automatically drains when the basin is full.
• The control panel clearly displays and records system operating status, including flush counts, fault alarms, and power indication.
• High-liquid level detection and intelligent control.
