STANK STH 775
Production Capacity: ~775 gallons per day, positioned between the 500 GPD and 1,000 GPD commercial-grade units.
Tankless, wall-mountable design: compact under-sink or vertical installation, no storage tank.
Filtration setup:
Sediment pre-filter (cleanable)
Carbon pre-filter (Green Coconut or KDF-based)
Multiple RO membranes (e.g., three 250 GPD modules) to reach ~750+ GPD
Selectable flow restrictors: 1:1 (efficient) and 2:1 (faster production) options.
Accessories included: membrane flush kit, tubing, housing wrench, shut-off valves, mounting bracket.
Estimated footprint: similar to existing models (e.g., ~18.5″ × 16″ × 6″), weighing roughly 12–15 lb.
Operating range: 40–125 psi water pressure, 40 °F to 110 °F working temperature.
Maintenance schedule: yearly sediment filter, carbon change after ~1,250–1,500 gal, RO membranes every 6 mo–2 yr, housings replaced every 3 years
