FAQ
1. What is the daily output?
250 L/H equals approximately 6,000 gallons per day (about 6 tons), enough for 500-600 people.
2. What type of water can this system handle?
Tap water or low TDS well water (TDS ≤ 1000 ppm). For high TDS or high hardness water, please see our models with additional stages.
3. Are the tanks FRP or stainless steel?
Standard configuration uses FRP (fiberglass reinforced plastic) tanks — corrosion-resistant and cost-effective. Stainless steel tanks are available upon request.
4. Does this system include a softener?
No. This is a standard 3-tank system (sand + carbon + cartridge). For high hardness water, we recommend our 6-tank model with softener.
5. What voltage does it need?
Standard 220V / 50Hz. 110V / 60Hz is available upon request.
6. How long does installation take?
About 4 hours. The system comes pre-assembled — just connect water inlet, drain, and power.
7. What is the MOQ?
1 set. OEM customization available for bulk orders.
