iLiving 12″ Wall Mounted Shutter Exhaust Fan
The 12-inch model delivers 960 CFM with a 1400 sq ft coverage range. It uses a 115V, 0.6A direct drive motor and a 1650 RPM rating, making it suitable for smaller shops, basements, or garages that require steady exhaust. The shutter is automatic, and the unit includes Thermospeed temperature control for a range of 32-130°F. The galvanized steel frame and aluminum shutters resist corrosion, and the setup is UL certified with a permanently lubricated motor.
Best for: Small workshops, garages, or greenhouses needing reliable, variable-speed exhaust without taking up much wall space. Avoid this if you need ultra-high airflow for very large spaces; the 12″ model is best for compact layouts.
Caution: Noise remains under 65 dB, but the compact unit may struggle in extremely large or hot spaces without multiple units. The recommended use is within its 1400 sq ft coverage.
iLiving 36″ Wall Mounted Shutter Exhaust Fan
This is a high-capacity solution designed for larger spaces like attics, warehouses, or expansive garages. It features a 6128 CFM output, 9000 sq ft coverage, and an automatic shutter design with durable aluminum shutters. The motor is fully enclosed and thermally protected, with corrosion-resistant construction for long-term use. The Thermospeed controller enables variable speeds across a temperature range of 32-130°F.
Best for: Large rooms or multi-area ventilation where strong airflow is essential. Choose this if you need to move significant air volumes quickly. Better for: users who want robust, low-maintenance operation in damp or hot environments.
Caution: Larger footprint requires a suitable wall opening and mounting space; ensure support structure can handle the weight and vibration of a big shutter unit.
iLiving 20″ Wall Mounted Shutter Exhaust Fan
This model blends substantial airflow with a practical 20-inch footprint, delivering 3368 CFM and coverage up to 5000 sq ft. It uses a 115V, 2.2A motor and a 980 RPM rating. The Thermospeed controller supports variable speeds and precise temperature control between 32-130°F. The full galvanized frame with aluminum shutters provides durability, while the motor is UL certified and permanently lubricated for low maintenance.
Best for: Long, wide or high-ceiling spaces like warehouses or large workshops needing strong, consistent exhaust. Better for: users prioritizing higher airflow with a wide coverage area.
Caution: Higher power draw (2.2A) means more energy use; plan electrical supply accordingly.
iLiving 18″ Wall Mounted Shutter Exhaust Fan
The 18-inch option delivers 1736 CFM and covers up to 2600 sq ft. It operates at 1075 RPM with a 0.85A draw, balancing airflow and power consumption. The Thermospeed controller enables varied speeds and a 32-130°F temperature range. It’s built with a galvanized steel frame and aluminum shutters, and the motor is UL listed with a permanently lubricated design. Noise remains below 65 dB.
Best for: Attic, greenhouse, or workshop ventilation where moderate to high airflow is needed without the largest footprint. Choose this if you want a mid-sized unit with strong performance.
Caution: Not ideal for extremely large open floor plans; you may want multiple units for uniform airflow across bigger spaces.
iLiving 30″ Wall Mounted Shutter Exhaust Fan
This 30-inch model offers an impressive 5088 CFM and 7500 sq ft coverage, making it suitable for large, open spaces like industrial rooms or expansive attics. The unit uses a durable aluminum shutter and corrosion-resistant steel frame. The shutter is automatic, and the system includes Thermospeed temperature control to modulate speed as conditions change. The motor is UL listed and permanently lubricated for low maintenance.
Best for: Very large areas where high-volume exhaust is required. Better for: settings needing strong, centralized venting with robust construction.
Caution: The substantial size requires ample wall area and proper mounting support; ensure compatibility with your space’s structure and electrical supply.
iLiving 16″ Wall Mounted Shutter Exhaust Fan
The 16-inch model balances airflow and space with 1200 CFM and 1800 sq ft coverage. It uses a 115V, 0.85A motor at 1550 RPM with Thermospeed control across a wide temperature range (50-99°F in this model description). The galvanized steel frame with aluminum shutters ensures durability, while the EC motor is OSHA-compliant and UL-listed for motor reliability. The design emphasizes low noise under 65 dB.
Best for: Medium-sized rooms or workshops where a compact yet capable exhaust is needed. Choose this if you want a mid-range option with good control and solid build quality.
Caution: Ensure the opening matches the 16-inch footprint and supports the shutter weight during wind loads or vibration.
Buying Guide: Key Purchase Considerations
- Space and coverage: Match CFM to room area and ceiling height. Large spaces demand higher CFM and possibly more than one unit for uniform ventilation.
- Shutter type and weather resistance: Automatic shutters reduce backdrafts and protect interiors. Aluminum shutters offer good moisture and heat resistance.
- Control features: Thermospeed and variable speeds let you tailor airflow to temperature and humidity, saving energy.
- Construction quality: Look for galvanized steel frames, corrosion-resistant components, and UL certification for reliability.
- Electrical considerations: Check motor amperage and ensure your electrical circuit can handle peak draws, especially for 20″ and 30″ models.
- Noise level: Most units stay under 65-69 dB; consider placement to minimize occupant disruption in living or work spaces.
- Maintenance: Permanently lubricated motors and sealed enclosures reduce upkeep. Verify accessibility for blade and shutter cleaning.
FAQ
- What airflow should I choose for a garage?
– For typical garages, aim for 600-1500 CFM per 1000 sq ft, adjusting for ceiling height and insulation. A mid-size unit or two smaller units can balance airflow and noise. - Are automatic shutters worth it?
– Yes. They prevent backdrafts, reduce moisture ingress, and shield interiors when the fan is off. - Can these fans be used in greenhouses?
– They can vent heat and humidity effectively, but ensure temperature and humidity ranges suit your specific crops and environment. - Is higher CFM always better?
– Not always. Oversized airflow can create drafts and waste energy. Choose CFM that matches space size and ventilation needs. - Do these require professional installation?
– Installation often involves wall cutting and electrical connections. A qualified technician is recommended if you lack experience. - What maintenance is needed?
– Periodically inspect shutters, clean blades, and verify motor lubrication. Ensure wiring guards remain intact for safety.
