Noise stays under 65 dB, contributing to quieter operation in occupied spaces. This model is UL-listed and designed for direct-drive reliability, with a permanently lubricated motor for low maintenance. Ideal for environments requiring steady airflow with temperature-responsive control.
HG Power 12 Inch Attic Fan With Thermostat
The HG Power 12-inch shutter exhaust fan emphasizes smart environmental management with temperature and humidity sensing. It delivers 971 CFM and includes a digital controller with a user-friendly display, enabling precise control. The fan uses an EC motor for efficient airflow with low noise, which is advantageous in living or working spaces adjacent to the installation site. A 9-hour timer option and up to 10 speed levels support energy-efficient operation while maintaining air quality. The shuttered design reduces backdraft and external ingress when not in use, and its strong construction suits attics, garages, sheds, or greenhouses.
iLiving 18″ Wall Mounted Shutter Exhaust Fan
With 1736 CFM and a 1075 RPM motor, this 18-inch model covers up to 2600 square feet. The Thermospeed Controller ILG8SFST supports adjustable speeds and thermostat-based regulation in a galvanized steel frame with aluminum shutters. It is UL listed for speed controllable, permanently lubricated operation and features corrosion-resistant guards—ideal for larger spaces such as warehouses, greenhouses, or workshops requiring substantial airflow and reliable temperature management. The built-in thermostat helps maintain comfortable conditions while controlling energy use.
iLiving 20″ Wall Mounted Shutter Exhaust Fan
This 20-inch unit pushes 3368 CFM at 980 RPM, designed for covering up to 5000 square feet. The Thermospeed Controller ILG8SFST offers speed and thermostat-based regulation, with a temperature range of 32°F to 130°F. The durable galvanized steel frame and aluminum shutters support extended use, with a low noise level under 69 dB. It’s suitable for large garages, industrial spaces, warehouses, or greenhouses where high airflow and precise climate control are essential. UL certification ensures compliance with electrical safety standards, while a permanently lubricated motor minimizes maintenance needs.
iLiving 16″ Wall Mounted Shutter Exhaust Fan
The 16-inch model delivers 1200 CFM and 1550 RPM, suitable for coverage up to 1800 square feet. It features a Thermospeed Controller ILG8SFST and a thermostat range from 32°F to 130°F, enabling automatic speed adjustments with temperature changes. The fan is built with a galvanized steel frame and aluminum shutters, prioritizing durability and corrosion resistance. It remains UL listed with a permanently lubricated motor and low noise output under 65 dB, making it a practical choice for workshops, garages, or medium-sized greenhouses requiring reliable ventilation and temperature regulation.
Buying Guide: Key Purchase Considerations and Comparisons
When choosing an extractor fan with a thermostat, consider airflow needs, space size, and installation constraints. The following factors help compare options:
- Airflow and coverage: Higher CFM suits larger spaces, but oversized units can underspend or cause unnecessary energy use in smaller rooms. Match CFM to the area’s size and typical activity level.
- Thermostat and control: Thermostat-enabled fans adjust speed based on temperature; digital controllers and presets simplify operation. Check available temperature ranges and the number of speed settings.
- Shutter design and durability: Automatic shutters prevent backdrafts and weather ingress. Look for galvanized steel frames, aluminum shutters, and corrosion resistance for long-term performance.
- Noise and motor type: EC motors are efficient and quiet, which matters in living or working spaces. Noise under 65 dB is common for residential/commercial models; higher performance units may reach higher dB in large spaces.
- Power, efficiency, and safety: UL listings indicate electrical safety compliance. Permanently lubricated motors reduce maintenance. Determine if 115V operation fits your electrical system.
- Installation footprint: Larger diameters require more mounting space. Ensure ducting, mounting hardware, and wiring routes are feasible in your space.
- Durability and warranty: Industrial-grade frames and corrosion-resistant materials extend service life, particularly in humid or dusty environments.
Cross-comparing the featured models shows a spectrum from compact 12-inch units to larger 20-inch fans. For small-to-medium spaces, the iLiving 12″ and 16″ models provide solid coverage with thermostat control. For larger areas such as warehouses or greenhouses, the 18″ and 20″ iLiving units deliver higher CFM and broader reach. The HG Power option adds a digital controller with humidity sensing, useful in spaces with fluctuating moisture levels. In all cases, thermostat-based speed control enhances energy efficiency by adjusting airflow to environmental conditions rather than running at a constant speed.
