Dera Manual Spray Gun

A manual spray gun is a versatile tool used for applying various coatings, from paints and lacquers to stains and primers, on a wide range of surfaces like wood, metal, plastic, and even walls. They offer more control than automated systems and are popular for both DIY projects and professional finishing.

There are several types of manual spray gun, primarily differentiated by how they atomize and deliver the paint:

Main Types of Manual Spray Gun:

• Conventional/Air Spray Gun: These are the most common. They use compressed air to mix with the fluid (paint) to atomize it into a fine mist.
  • Advantages: Versatile, can handle a wide variety of fluids and target objects, and can achieve a good finish.
  • Disadvantages: Can have significant overspray, leading to paint waste and VOC emissions.
  • Feeding Methods:
    • Gravity Feed (Top Cup): The paint cup is on top of the gun, and gravity helps feed the paint to the nozzle. Ideal for smaller projects and automotive refinishing, offering good control and less paint waste.
    • Suction Feed (Bottom Cup): The paint cup is located below the gun, and compressed air creates a vacuum to siphon paint up. Less common but suitable for low to medium viscosity paints.
    • Pressure Feed: The paint is supplied from a separate pressurized tank or pump, often used for high-volume industrial applications.
• HVLP (High Volume Low Pressure) Spray Gun: These use a higher volume of air at a lower pressure to atomize the paint.
  • Advantages: Significantly less overspray than conventional gun (higher transfer efficiency), resulting in less material waste and a healthier environment. They produce a finer spray pattern and are excellent for detailed work, cabinets, furniture, and water-based paints.
