What is a DeWalt 20V Blower

A blower is a type of fan that pushes air in one direction. Blowers are typically used to move large volumes of air at relatively low pressures and can be used for cooling, ventilation, or exhaust purposes. They are popular in industrial and commercial applications as they are reliable and cost-effective.

Blowers work by rotating an impeller inside the housing, which draws in air at one side of the unit and forces it out the other side. The air is forced through a series of blades attached to the impeller, creating a low-pressure area on the intake side and a high-pressure area on the outlet side. This pressure difference causes air to flow from one end to the other.

In order to control the amount of air that is moved, blowers are either equipped with adjustable speed motors or variable pitch impellers. The speed motor will allow for greater control over the airflow while a variable pitch impeller can be adjusted to match specific pressure requirements.

Blowers have many uses in industrial and commercial settings, including powering HVAC systems, providing forced cooling for machinery, as well as exhaust ventilation. They are also used in agricultural applications such as greenhouse fans, grain dryers, and crop dusters. Blowers can provide more efficient cooling than a traditional fan by creating a directional flow of air which helps to reduce energy consumption.

A DeWalt 20V Blower is a kind of handheld electric blower that utilizes the latest in cordless technology. It is powered by a powerful, yet compact, 20-volt MAX lithium-ion battery providing up to 125 mph air speed and 100 CFM of air volume power. This makes it ideal for clearing away debris like leaves and grass clippings from your yard or driveway quickly and efficiently. In addition to its efficient power output, the blower also features an ergonomic design that reduces user fatigue when operating for long periods of time. With this combination of features, it’s no surprise the DeWalt 20V Blower has become one of the go-to tools for gardeners and landscapers alike. [1], [2], [3]

Common Issues With DeWalt 20V Blower

Despite its powerful performance, the DeWalt 20V blower can experience a range of issues due to common user errors or poor maintenance. It’s crucial to be aware of those issues and know how to address them in order to keep the blower running optimally. In this article we will discuss some of the most common issues associated with DeWalt 20V blowers and provide tips on how to address them.

Excessive vibration

One of the most common problems with a DeWalt 20V blower is excessive vibration. This can be caused by several things including, but not limited to, loose or damaged parts, incorrect assembly, and worn bushings. To address this issue it is important to first check that all parts are properly tightened and undamaged. If any parts appear to be damaged or missing then they should be replaced as soon as possible.

Focus on fans or impellers first as these are the components that tend to cause the most vibration. Make sure the impeller is securely attached and not loose or bent. If the blades appear to be worn down, it may be necessary to replace them in order for the blower to operate correctly. Additionally, check for any debris or dirt which could be causing extra friction and resulting in excessive vibration.

If all parts appear to be in good condition, then it’s possible that there is a worn fan bearing or bushing. This can be the result of heavy usage and age, but can also be caused by improper lubrication. To check for worn bushings, use a flashlight to inspect the fan assembly from all angles and make sure that there are no visible signs of wear or damage. If bushings appear to be worn, then it is recommended to replace them with new ones.

Common Issues With DeWalt 20V Blower

The blower doesn’t blow air

The other common issue with the DeWalt 20V blower is that it simply doesn’t blow air. This can happen when the battery isn’t properly connected or if the impeller is blocked by debris. The first thing to check is the battery connections, as a loose connection will prevent power from reaching the motor and thus won’t allow it to spin up. If everything appears to be connected correctly, then it’s likely that there is an obstruction blocking the impeller. Be sure to inspect the inside of the housing and remove any obstructions before attempting to use it again.

Faulty fans or tubes can also cause a lack of airflow. Check for any signs of damage to the fan or tube, such as cracks or tears, and replace with genuine DeWalt parts if necessary.

Finally, it is possible that there is simply not enough power to spin up the motor. Make sure that the battery is fully charged before attempting to use it again and if that doesn’t solve the issue then contact your local DeWalt service center for assistance.

Blower keeps shutting off

Another annoying issue that can arise with the DeWalt 20V blower is that it keeps shutting off unexpectedly. This can be caused by a variety of different issues, ranging from user error to poor maintenance.

One of the most common causes of this issue is that the battery may not have been fully charged before use. Even if the battery appears to be at full charge when first used, its performance may degrade over time and could cause the blower to shut off after only a few minutes of use. To avoid this issue make sure you always charge your battery for at least 8 hours before using it.

Another potential cause could be damaged wire connections that can occur if the blower has been stored improperly or dropped while in use. Make sure to check all connections and replace any damaged parts as necessary.

Finally, check the air filter of your DeWalt 20V blower. If dirt and other debris accumulate in the filter, it can restrict airflow and cause the blower to shut off prematurely. Clean your air filter regularly to ensure optimal performance.

Blower making rubbing or clicking sound

Another of the most common issues associated with DeWalt 20V blower is when it starts making a rubbing or clicking sound. This issue can be caused by dirt or debris accumulating in and around the fan, which causes friction between the fan blades and the housing. In order to fix this issue, it’s important to locate the source of interference and remove any blockages. Additionally, you should also clean out all airways using compressed air or a vacuum cleaner to ensure that no further blockages occur.
