Key Specs

What Specifications Matter Most

Flush Volume (0.5–1.2L)

The lower the better for tank capacity management. GenX systems use 0.5L — check competitor claims carefully.

Tank Capacity (100–400L)

Larger tank = fewer pump-outs. For a sleeper bus with 40 passengers, a 200L tank typically lasts 3–4 days.

Operating Voltage (24V DC)

Must match your bus electrical system exactly. 12V systems are underpowered; 230V AC requires an inverter.

Bowl Material (SS304)

Stainless steel 304 is the minimum standard. Avoid plastic bowls — they stain, crack and smell within 12 months in Indian conditions.

Vacuum Level (300–500 mbar)

Higher vacuum = more reliable flushing at any speed or incline. Check rated vacuum, not just marketing claims.

Noise Level

Vacuum pumps can be loud. Ask for dB rating — anything above 72 dB will disturb passengers in a sleeper bus.
