EPS Plus · Whole House Fan · 1,000–2,200 sq. ft. homes
The Solatube EPS Plus draws cooler outdoor air through open windows and moves accumulated indoor heat into the attic, where it exits through the home's attic vents.
Its EC brushless motor, seven variable speeds, insulated ducting, and HushMount™ 2 system deliver strong whole-home airflow with precise control and reduced vibration.
Plan before ordering: EPS Plus requires approximately 4 sq. ft. of net-free attic ventilation, adequate attic space for the fan and duct path, accessible electrical power, and open windows during operation.

Comfort on your terms
Use the EPS Plus when outdoor conditions are cooler than the air inside your home to improve comfort and reduce reliance on air conditioning.
Moves up to 2,502 CFM through medium-size homes and helps release heat accumulated during the day.
Choose lower airflow for everyday ventilation or increase the speed when you want a faster air exchange.
The included Comfort Control Remote lets you turn the fan on and adjust airflow without accessing the attic.
The brushless motor and Soft Start technology provide efficient operation and a smooth ramp to the selected speed.
HushMount™ 2, Jet Blade design, and insulated ducting work together to reduce transmitted sound and vibration.
The fastener-free intake grille provides a finished appearance and removes easily for sink or dishwasher cleaning.
Engineered Performance Series

A complete air exchange
A whole house fan depends on open windows and adequate attic exhaust ventilation. It does not refrigerate or dehumidify the air like an air conditioner.

Choose the right capacity
Select a fan using the home's size, required airflow, available attic space, and net-free attic ventilation.

| Model | Suggested home size | Maximum airflow | Attic venting required | Sound, low/high |
|---|---|---|---|---|
| EPS Focus | 0–500 sq. ft. | 259 CFM | 1 sq. ft. | 30 dB |
| EPS Zone | 500–1,200 sq. ft. | 1,400 CFM | 2 sq. ft. | 40/48 dB |
| EPS Plus Current model | 1,000–2,200 sq. ft. | 2,502 CFM | 4 sq. ft. | 44/58 dB |
| EPS Ultra | 2,000–3,200 sq. ft. | 3,785 CFM | 6 sq. ft. | 50/58 dB |
| EPS Extreme | 3,000+ sq. ft. | 4,567 CFM | 8 sq. ft. | 58/64 dB |
Home size is a starting point. Confirm the fan capacity, attic venting, attic clearances, climate, and local requirements for the specific installation.
EPS Plus system
Plan for installation supplies: confirm all required mounting, sealing, electrical, and code-required materials before beginning installation.

Plan the installation
Before installation, confirm that the attic can accommodate the fan assembly and seven-foot duct path and that the home provides adequate net-free attic ventilation.
