VENTS-US Twinfresh Expert RA1-50-2 Ventilation Fan
Free!
- The TwinFresh though-the-wall ERV fan supplies fresh air indoors and exhausts stale air outdoors while recovering energy, which lowers the load on the HVAC unit as well as your energy bill
- Whisper Quiet Sound Level: From 0.3 to 0.6 sones at ten feet during operation
- Air Purification: All Twinfresh units come standard with MERV Five filtration (with a potential MERV Fourteen add-on)
- Ventilation Mode: One unit in the ventilation mode can provide fresh air circulation for rooms up to 500 square feet
- Air Flow Capacity: The TwinFresh Expert RA1-50-2 ventilation fan provides up to 30 CFM
- Energy Efficient Ventilation Fan: Unit features a rectifier for AC power supply applications with a low energy demand from 2.49 Watts
- Wall Thickness: The Twinfresh Expert ERV fan can be installed in a wall from 5-7/8″ minimum to 19-5/8″ maximum
- Stainless Steel Exterior Vent Cover: The powered finish and corrosion proof outer hood fits nearly any exterior
- A Note on Negative VS Positive Pressure: In regeneration mode, supply and exhaust cycle every seventy seconds. At a thirty CFM rate (in one direction), this results in a negligible amount of pressure gain or loss
