Type: Pneumatic Control Mechanism for Vacuum Toilet
Net Weight: Approx. 370~380g
Drive Type: Fully Pneumatic (No power supply required)
Water Consumption per Flush: ~1.2L
Material: High-strength corrosion-resistant engineering plastic & sealing components
Application: EVAC marine vacuum toilet & vacuum sewage system
Application Scenarios: Cargo vessel, cruise ship, offshore platform, railway vacuum toilet
Working Principle
Fully pneumatic sequential control. Pressing the flush button sends an air pulse to this controller. It opens the water valve first for bowl rinsing, then triggers the discharge valve after a short delay. Waste is sucked into the vacuum sewer pipeline by negative pressure. It automatically resets after the cycle, equipped with vacuum sensor and flush memory. Only ~1.2L water per flush, no power supply required.
Application Scenarios
Compatible with EVAC 90/900/910 marine vacuum toilets. Widely used on cargo ships, cruise vessels, tankers, offshore platforms and yachts. Also serves as replacement spare part for vacuum toilet systems on railway transit.
Maintenance
Regularly inspect seals for aging and air leakage
Clean impurities in water & air passages to prevent jamming
Replace matching seal repair kit preferentially instead of whole unit when faulty
Annual preventive maintenance is recommended
Acceptance
Factory air tightness test & cycle operation test; visual inspection and pneumatic function test available on arrival, factory test record available.
