ERI PX-Q300 Quiet-Series Pressure Exchanger: Specs, Manual, Pricing
The ERI PX-Q300 is the quiet-series upgrade of the standard PX-300, delivering 98%+ pressure transfer efficiency at 71 dB(A) — 7 decibels quieter than the standard PX-300. Designed for hotel resorts, hospitals, and residential-adjacent SWRO installations where ambient noise matters, the PX-Q300 maintains the 300 GPM (68 m³/h) flow rating of the standard model with refined rotor geometry that reduces vibration and acoustic emission.

What Makes the Q-Series Different
The Q-series rotor uses optimized duct geometry and tighter manufacturing tolerances:
- Acoustic emission reduced from 78 dB(A) (standard PX-300) to 71 dB(A) — about half the perceived loudness
- Vibration amplitude reduced ~40%
- Pressure transfer efficiency improved from 97% to 98%+
- Lower bearing-zone temperature, extending rotor life beyond 100,000 hours
- Otherwise identical mounting footprint to PX-300 — direct retrofit possible

When to Specify PX-Q300 Over Standard PX-300
| Choose PX-Q300 if... | Standard PX-300 fits if... |
|---|
| Installation is in or near guest rooms / occupied space | Equipment room is acoustically isolated |
| Local noise codes apply (resort, hospital, urban) | Industrial setting with no occupancy |
| System runs 24/7 (efficiency gain compounds) | Intermittent operation |
| Energy cost is dominant OPEX driver | Capital cost optimization is priority |
Installation, Maintenance, and Service Life
Identical to standard PX-300 (mounting, pre-filtration, ambient range, brine return piping). Service life expectancy 25+ years for housing, 10+ years for rotor. ForeverPure provides commissioning support and long-term service contracts globally.
