## Description

VENTS-US TwinFresh Comfo RB1-50-2 - Ductless Through-the-Wall Single Room Energy Recovery Ventilation Fan with Remote Control, Continuous Ventilation, and Indoor Humidity Control: desertcart.com: Tools & Home Improvement

## Features

- Fresh Air and Year-Round energy savings: The TwinFresh Comfo Ventilation Fan maximizes energy efficiency. Provides up to 30 CFM of fresh, filtered air to rooms up to 500 sq ft while recovering up to 88% of heat or cooling, helping reduce HVAC load and energy costs in your home. In the winter, it recovers heat from outgoing air to warm incoming fresh air, reducing furnace load and energy costs. In the summer, it pre-cools incoming air, lessening the strain on your air conditioner and lowering your A/C cooling bills
- Ductless through-the-wall ERV solution: Compact ductless energy recovery ventilator installs through walls 6–20 inches thick, making it ideal for bedrooms, basements, home offices, and tiny homes where traditional ductwork or a “vent in the room” is not feasible
- Features efficient reversible DC Motor: The Twinfresh Comfo ERV ventilation fan features a high-efficiency reversible DC motor that operates as quietly as 0.2 sones while using as little as 4.5 watts. The built-in overheating protection and ball bearings ensure reliable, long-term operation
- Humidity control and cleaner indoor air: Built-in humidity sensor automatically responds to excess moisture, while MERV 5 filters help reduce dust, pollen, and odors for healthier indoor air quality
- Modern exterior and easy installation: Includes a corrosion-resistant stainless steel exterior hood, interior grille, and wireless remote control for simple installation, easy maintenance, and convenient control of your single-room ventilation system
- Rated for continuous operation: Built for continuous air exchange and everyday use, the TwinFresh Comfo helps maintain fresher indoor air without needing to run only on occasion, making it a smart solution for bedrooms, living spaces, renovations, and occupied rooms that need reliable airflow
- Frost and Condensate-free Performance: Designed for dependable operation in demanding conditions, this single-room ERV is frost- and condensate-free and rated for outside air temperatures down to -4°F, helping support year-round fresh air exchange in cold-weather climates
- Sound Level Performance: With sound levels as low as 0.2 to 0.5 sones, this through-the-wall ERV is barely audible in normal use, making it ideal for bedrooms, nurseries, guest rooms, offices, and other spaces where low-noise performance matters
- Simpler alternative to traditional ERV systems: Unlike many conventional ERV setups, the TwinFresh Comfo does not require ductwork, balancing, a separate mechanical room, or extensive interior work to hide ducts, making it a cleaner solution for remodels, retrofits, additions, and tight spaces
- Room-by-room ventilation with scalable airflow: Designed for spaces up to 500 sq. ft., the TwinFresh Comfo delivers targeted air exchange where it matters most. Install one unit per room or pair multiple units for larger areas—units can operate independently or be connected in primary-secondary mode to create a continuous, whole-home ventilation system without bulky ductwork
