funnel spray gun with air compressor for cement mortar

This funnel spray gun design is commonly used in applications that require larger spray volumes, such as automotive refinishing and large area painting.

The Working Principle of the Funnel Spray Gun

Air compressor to provide power: Funnel-type spray gun through the connection to the air compressor, the use of compressed air to promote the spraying liquid (such as paint, paint, etc.) from the nozzle spray.
Funnel design: The storage part of the gun is in the shape of a funnel, which can hold more liquid and is suitable for jobs that require a large amount of paint. The liquid flows into the gun from the funnel and is sprayed out through the thrust of compressed air.
Air flow and liquid flow control: Users can adjust the air flow and liquid flow to control the spraying effect, such as spraying width, coating thickness and so on.

Application Areas of Funnel Spray Gun

Automobile painting: Commonly used in automobile repair and painting, because the spraying volume is large enough to cover the surface of the body.
Construction painting: It is also used in spraying paint on large wall or other building surfaces, especially where an even coating is required.
Furniture and woodworking painting: For painting wooden furniture, the spray gun can provide smooth and even coating.
Crafts and Models: For certain applications where a fine coating is required, funnel guns are also suitable.

Advantages of Funnel Spray Gun

Higher spraying efficiency: Due to the funnel design, it can hold more paint, reducing the need for frequent refilling.
Suitable for coating large areas: More efficient than small guns in situations where large amounts of liquid need to be sprayed.

Disadvantages of Funnel Spray Gun

Larger weight: Due to the larger storage design, it may be relatively heavier, requiring more control and operating skill when using it.
Coarser spraying: Funnel guns may be better suited for coating large areas than fine spray guns for very fine spraying jobs.
