Alorair 120 vs Storm 170 Comparison
Moisture Removal Capacity
The AlorAir Storm 170 PPD Dehumidifier offers significantly higher moisture extraction than the AlorAir 120-Pint Crawl Space Dehumidifier with Pump. Under saturation conditions, the Storm model removes up to 170 pints per day, while the 120-Pint model handles 120 pints. When tested under standard AHAM conditions, the Storm unit removes 80 pints daily compared to 55 pints for the 120-Pint version. This makes the Storm 170 the stronger choice for very wet environments or larger areas where rapid drying is essential. The 120-Pint model remains efficient for standard crawl spaces but has a lower ceiling for extreme humidity loads.
Coverage Area
Coverage area is a key factor when selecting a dehumidifier for your specific space. The AlorAir Storm 170 PPD Dehumidifier with Pump is rated for spaces up to 2,100 square feet. In contrast, the AlorAir 120-Pint Crawl Space Dehumidifier with Pump covers areas up to 1,500 square feet. If you are treating a large basement, commercial warehouse, or extensive crawl space, the Storm 170 provides the necessary capacity to handle the volume. The 120-Pint model is well-suited for smaller, contained areas. You should match the square footage rating to your room size to ensure adequate performance without overworking the unit.
Build and Design
The construction materials and physical form factor differ between these two units. The AlorAir Storm 170 PPD Dehumidifier features a rotomolded housing, which is impact-resistant and resists warping in demanding environments. It is colored light green and measures 24.8 inches in height. The AlorAir 120-Pint Crawl Space Dehumidifier with Pump has a corrosion-resistant casing designed for dust and moisture, colored white, and stands 14.2 inches tall. The Storm 170 is taller and heavier at 63.9 pounds, while the 120-Pint model is more compact at 41.7 pounds. The rotomolded design of the Storm offers distinct durability advantages for rough handling.
Portability and Dimensions
Mobility and physical footprint matter if you need to move the unit or fit it into tight spaces. The AlorAir 120-Pint Crawl Space Dehumidifier with Pump is smaller and lighter, weighing 41.7 pounds with dimensions of 17.9 inches in length and 12.6 inches in width. The AlorAir Storm 170 PPD Dehumidifier with Pump is larger and heavier, weighing 63.9 pounds, with a height of 24.8 inches. However, the Storm 170 includes sturdy wheels and a retractable handle, facilitating movement across floors. The 120-Pint model lacks mentioned wheels, suggesting it is intended for stationary installation. Choose the 120-Pint for a smaller footprint, or the Storm 170 if you need wheels for transport.
Efficiency Technology
Energy efficiency and technology type vary between the models. The AlorAir Storm 170 PPD Dehumidifier utilizes LGR (Low Grain Refrigerant) technology and boasts a COP of 2.4 L/kWh, indicating high efficiency in moisture removal per unit of energy. It also delivers 200 CFM of airflow to maximize drying speed. The AlorAir 120-Pint Crawl Space Dehumidifier with Pump uses an advanced R32 refrigerant system for efficient humidity control. While specific COP or CFM figures are not provided for the 120-Pint model, its R32 system is noted for modern efficiency. The Storm 170 provides explicit efficiency metrics and higher airflow, which may benefit large-scale drying tasks.
