The TwinFresh Expert RW1-100-2 V.2 is the most powerful model in the TwinFresh Expert Ductless RW ERV lineup, designed to deliver balanced fresh air ventilation for larger rooms, living spaces, offices, bedrooms, tiny homes, passive houses, and light commercial applications.

With a rated maximum airflow of 64 CFM in ventilation mode, this single-room ductless energy recovery ventilator helps provide fresh, filtered outdoor air while exhausting stale indoor air, all without the need for traditional ductwork. It is ideal for spaces up to 820 sq. ft., making it a strong choice for renovations, room additions, apartments, cottages, and high-performance homes where indoor air quality matters.

Smart Ductless Ventilation with Wireless Control

The TwinFresh Expert RW1-100-2 V.2 includes built-in wireless connectivity, allowing you to control one unit or multiple connected units using the compatible iOS or Android app. Adjust ventilation settings, monitor performance, and optimize airflow directly from your smartphone.

Whether you are managing a single bedroom, a home office, or multiple rooms in a larger project, the wireless control system makes it easy to fine-tune fresh air delivery based on your comfort and ventilation needs.

Energy Recovery for Year-Round Comfort

As a Ductless Energy Recovery Ventilator, the TwinFresh Expert RW1-100-2 V.2 helps improve indoor air quality while reducing energy loss. Its high-efficiency ceramic energy recovery core transfers heat between outgoing stale air and incoming fresh air, helping maintain a more comfortable indoor temperature in both heating and cooling seasons.

With energy recovery efficiency up to 87%, this unit helps reduce strain on heating and cooling systems while supporting continuous fresh air circulation.

Fresh Air for Tight, Efficient Spaces

Modern homes, Tiny homes, passive houses, and renovated spaces are often built or upgraded to be more airtight. While this can improve energy efficiency, it can also trap humidity, CO₂, odors, and stale air indoors.

The TwinFresh Expert RW1-100-2 V.2 helps solve that problem by providing controlled fresh air ventilation without opening windows or installing a full ducted system. Built-in humidity sensing helps the unit respond to changing indoor conditions, making it a practical solution for compact, efficient, or hard-to-ventilate spaces.

Easy Through-Wall Installation

This Ductless ERV is designed for through-wall installation and requires a minimum wall thickness of 5 7/8 inches. The unit connects through a 6 1/4-inch duct opening and includes the required exterior hood and remote control.

Because no traditional ductwork is required, the TwinFresh Expert RW1-100-2 V.2 is well suited for retrofit projects, multi-family buildings, home additions, cottages, apartments, and single-room ventilation upgrades.
