20 Inch vs 18 Inch Fan Specs
Blade count
The Allsheen 18-Inch DC Metal Pedestal Fan uses a five-blade design. This configuration moves air more efficiently than standard three-blade models. You get a stronger yet smoother and more consistent breeze. The extra blades help deliver comfortable cooling without a harsh or choppy feel. In contrast, the Allsheen 20-Inch Metal Pedestal Fan features aluminum blades. The data does not specify the exact number of blades for this larger model. However, the five-blade setup on the 18-inch unit is explicitly highlighted for its airflow quality and efficiency compared to traditional designs.
Speed settings
You have more control with the Allsheen 18-Inch DC Metal Pedestal Fan. It offers five precise speed settings. This range lets you choose from a gentle night-time breeze to a turbo-powered wind. The Allsheen 20-Inch Metal Pedestal Fan provides only three speed settings. You can select low, medium, or high speeds. This covers gentle personal cooling to maximum-power ventilation. If you need finer adjustments for specific comfort levels or quiet operation, the five-speed option gives you more granular control over the airflow intensity.
Oscillation
The Allsheen 18-Inch DC Metal Pedestal Fan includes automatic oscillation. It covers a wide 135-degree angle. You can set this with one button for hands-free, whole-room air circulation. This feature helps eliminate hot and cold spots in your space. The data for the Allsheen 20-Inch Metal Pedestal Fan does not mention oscillation. It describes a manually tilting head instead. This allows you to direct the focused breeze exactly where needed. If you want automatic, wide-range air distribution without adjusting the fan manually, the 18-inch model is the better choice.
Motor type
The Allsheen 18-Inch DC Metal Pedestal Fan uses an advanced DC motor. This technology cuts operating noise by more than half compared to traditional fans. It delivers high-velocity airflow while remaining ultra-quiet. This is ideal for bedrooms or offices where noise matters. The Allsheen 20-Inch Metal Pedestal Fan uses a thermally protected motor. It generates a powerful 8.2 m/s wind and operates quietly. However, the data does not specify if it uses DC or AC technology. The explicit DC motor on the 18-inch model offers a verified noise reduction benefit.
Blade material
The Allsheen 20-Inch Metal Pedestal Fan features balanced aluminum blades. Aluminum is lightweight and durable, contributing to the fan's high velocity performance. The data does not specify the material for the blades on the Allsheen 18-Inch DC Metal Pedestal Fan. It only notes the five-blade design. If you prefer the specific benefits of aluminum construction, such as balanced weight for high-speed operation, the 20-inch model provides that detail. The 18-inch model focuses on the efficiency of its blade count rather than the specific material composition.
Weight
The Allsheen 18-Inch DC Metal Pedestal Fan weighs 14.7 pounds. The Allsheen 20-Inch Metal Pedestal Fan weighs 11.5 pounds. The heavier weight of the 18-inch model often correlates with a more substantial base and construction. Both units feature heavy-duty metal bases for stability. The 18-inch model's extra weight may provide slightly better stability at its maximum height. The 20-inch model is lighter, which might make it slightly easier to move if needed, though both are designed for stationary use.
Choose the right Allsheen fan for you
You want whole-room circulation without manual adjustments
The 18-inch DC model features 135-degree auto oscillation. This spreads air across a wider area, eliminating hot spots in your living room or office. You get five speed settings for precise control. The five-blade design creates a smoother breeze. This automated movement saves you from having to tilt the head manually.
You need maximum wind speed for large spaces
The 20-inch fan generates a powerful 8.2 m/s wind. Its larger 20-inch size and three aluminum blades deliver high-velocity airflow. This model is built for rapid cooling in warehouses, garages, or large rooms. You get three speed settings for targeted ventilation. The heavy-duty metal construction ensures stability during high-speed operation.
You prefer a lighter fan that is easy to move
The 20-inch model weighs 11.5 pounds. This is lighter than the 18-inch DC version, which weighs 14.7 pounds. The reduced weight makes it easier to reposition around your home or workshop. You still get the same adjustable height range from 47 to 55 inches. The lighter frame does not compromise the sturdy metal base.
