Ampac USA-Reverse Osmosis 100~1200 GPD

This capacity range covers restaurants serving 50 to 200 customers daily, small office buildings, coffee shops, car detailing operations, dental offices, and light commercial applications needing low-TDS process water. At 100 GPD, a system runs roughly 4 hours per day to fill a storage tank sized for peak demand. At 1,200 GPD, continuous operation supports moderate production demands.

AMPAC USA systems in this range use FILMTEC TW30 or equivalent commercial-grade spiral-wound membranes with 96 to 98 percent TDS rejection. Membrane sizes are standard 4-inch diameter by 40-inch length, widely available for replacement. Each system is sized with appropriate membrane count and staging to hit product water targets based on the customer feed water analysis.

Standard automation includes daily or cycle-triggered membrane flush to prevent biofilm accumulation, low-pressure shutoff that protects membranes if feed pressure drops below 40 PSI, high-pressure shutoff, and automatic shutdown when the storage tank reaches full capacity via float or pressure signal. An audible alarm and indicator light signal fault conditions without requiring continuous monitoring.

Minimum inlet pressure is 40 PSI for satisfactory membrane performance. Optimal range is 60 to 80 PSI, which is typical municipal main pressure. Sites with pressure below 40 PSI require a booster pump, sold as an add-on option. Sites exceeding 100 PSI need a pressure-reducing valve upstream to prevent membrane and housing damage.

Membrane life in small commercial service is typically 3 to 5 years with proper pre-filtration and periodic flushing. Sediment and carbon pre-filters require replacement every 6 to 12 months depending on feed water quality. The easiest performance indicator is product water TDS: when it climbs more than 15 to 20 percent above baseline, membrane inspection or cleaning is the next step.

Standard installation needs a cold water supply line connection (3/4-inch or 1-inch depending on system size), a drain connection for concentrate discharge at 30 to 50 percent of feed flow, a product water line to a storage tank or direct-use point, and a standard 120V electrical outlet for the controller and automatic flush valve. Most installations complete in 2 to 4 hours.
