Hot air blower for drying

Types of hot air blowers for drying

Hot air blowers for drying are invaluable tools in various industries. They provide a consistent supply of hot air to dry or cure wet surfaces, materials, products, and equipment. Depending on the heat source or the technology utilized to generate and supply hot air, the following types of hot air blowers for drying are popular.

• Electric hot air blowers for drying

  This type of hot air blower utilizes electricity as its source of power. The machine has a built-in heater element that produces heat when electricity flows through it. It is common for blowers to have a fan that blows the hot air out. Electric hot air blowers are support handy tools that can dry surfaces and materials quickly. They are also easy to operate, generally coming with a simple control set that allows one to change the blow's temperature and speed.

  Since it doesn't rely on fuels or gases to operate, an electric hot air blower for drying eliminates the risk of fire hazards. It also doesn't blow out any toxic fumes. As such, users can use the tool indoors and around flammable materials.

• Gas hot air blowers for drying

  Gas-powered blowers use natural gas or propane as their fuel to produce heat. Similar to electric hot air dryers, gas blowers also come with a fan that propels the hot air out.

  Gas hot air blowers are typically more powerful than their electric counterparts. They also heat up faster, which is a great advantage for outdoor applications. However, users need to consider some safety issues before using gas blowers. Such tools are best for use in well-ventilated environments where there is no risk of flammable materials around.

• Infrared hot air blowers for drying

  Infrared hot air blowers for drying utilize infrared technology to generate heat. Infrared radiation heat the objects directly without going through an intermediate. This process makes infrared heat blowers offer faster drying times. They also have the advantage of requiring low air flow to achieve drying. The low airflow means less dust and debris getting into the material being dried.

  Unfortunately, infrared hot air blowers are expensive, which can be a setback for some users.

• Hot air gun blowers for drying

  A hot air gun is a portable tool with a self-contained electric heating element and a fan. The gun works by forcing ambient air over a heating element and out into the environment as hot air. Hot air gun blowers can produce high temperatures up to 650°C and have adjustable fan speed/power settings.

  Air guns are versatile, portable, and affordable. They are more than just a hot air blower for drying. They can be used for various other applications, including bending plastic and wood, removing paint, thawing pipes, welding, and desoldering electronic components.

  However, just like infrared dryers, the airflow of a hot air gun is limited. Users may need to direct the hot air onto the object for more processing time. Also, exposure to high temperatures for an extended period can damage heat-sensitive materials.

  Moreover, running the tool at high temperatures can speed up the tool's wear and shorten its lifespan.

Specification and maintenance of hot air blowers for drying

The specifications of the heat blower will differ according to the type and model. However, some common specifications to note include the:

• Voltage: Hot air dryers will generally have a voltage rating of between 220V and 240V. Higher-voltage models, such as 400V, are used for industrial applications.
• Wattage: The wattage of the dryers can vary between 500 watts to 5,000 watts. Higher wattage means a hotter temperature. It will also impact the speed and efficiency with which it can dry products.
• Temperature: The temperature setting will vary according to the model. Certain dryers can produce temperatures as high as 650 degrees Celsius.
• Airflow: The airflow is measured in cubic feet per minute (CFM). It indicates the volume of air that is released by the blower. The CFM ratings will range from 1,000 to 12,000. Higher CFM will reduce the time taken to dry any wet product.
• Noise level: The level of noise is measured in decibels (dB). It is essential to consider the impact of noise pollution in the surrounding areas. Some dryers produce a noise level between 80 to 90 decibels. Users may need to wear ear protection if the blower is used for extended periods.

Maintenance

It is essential to maintain the hot air blower to extend its lifespan and improve its performance. Regular maintenance will ensure that the blower will continue to produce the high temperatures and airflow required to dry products.

Before starting the maintenance process, be sure to read the user manual and follow all instructions as outlined by the manufacturer. Switch off the hot air dryer and disconnect it from the power source before carrying out any maintenance or cleaning.

Inspect the entire unit for any signs of damage or wear. Look for loose or frayed electrical connections. If any part is damaged, it must be repaired or replaced by a qualified technician before it can be used again.

Use compressed air to blow out any dust or debris that has settled into any small openings or around the heating element. A soft brush can also be used to clean out any hard-to-reach areas of the device. Please do not use water to clean the blowers as it will damage the electrical parts.

Use a clean, dry cloth to wipe any larger parts of the dryer. This process will remove any moisture that is settled on the unit.

Ensure that the fan is rotating smoothly and freely. There should not be any accumulation of dust or debris on the blades. The drying fan should be cleaned regularly so that the blower can function optimally.

Scenarios of hot air blower for dryings

The wide applicability of the hot air blower for drying is evident in diverse industries and fields that use it regularly in the manufacturing, assembly, maintenance, arts and crafts, packaging and food industries and others. Below is a summary of some use scenarios of a hot air gun for drying:
