What Is HVLP Spray Gun?
HVLP stands for High-Volume Low-Pressure, and is a type of spray gun that uses air from an air compressor to atomize paint or lacquer. This method is much more efficient than traditional methods, as it puts less strain on the environment (as there is far less overspray) and provides superior finish quality. HVLP spray guns are the preferred method of spray painting and staining for many professionals, as they produce superior results with less effort.
Types of HVLP Spray Guns:
There are several different types of HVLP spray guns available, each with their own unique features and capabilities. The most common types of HVLP spray guns are:
1- Gravity-Feed HVLP Gun
2- Siphon-Feed HVLP Gun
3- Turbine-Powered HVLP Gun
1- Gravity-Feed HVLP Gun:
Gravity-feed HVLP guns are the most common type of spray gun, as they are low cost and easy to use. They work by utilizing gravity to draw paint from a cup or container attached directly to the gun handle.
2- Siphon-Feed HVLP Gun:
Siphon-feed HVLP guns utilize a tube that is connected to a container of paint or lacquer, which is then drawn up into the gun and sprayed. These guns are more powerful than gravity-feed guns and are capable of producing higher quality finishes.
3- Turbine-Powered HVLP Gun:
Turbine-powered HVLP guns utilize air from an air compressor to atomize the paint or lacquer. These guns are the most powerful of all HVLP guns and produce the highest quality finishes.
7 Important Factors to Consider When Selecting an Air Compressor for HVLP Spray Gun:
When selecting an air compressor for HVLP spray gun, it is important to consider the following factors:
1. PSI Rate:
PSI (pounds per square inch) measures the amount of pressure being delivered by a compressor. The higher the PSI, the more powerful the compressor will be. Most HVLP guns require at least 8-10 PSI for proper operation.
2. Horsepower:
HP (horsepower) measures the amount of power being delivered by a compressor. Generally speaking, the higher the HP rating, the more powerful and efficient your compressor will be.
3. Tank Size:
Tank size is an important factor to consider when selecting an air compressor for HVLP spray gun. The larger the tank, the more air that can be stored and used, this means you’ll have more consistent flow while spraying. A larger tank also helps reduce noise levels created by a compressor.
4. CFM Air Output:
CFM (cubic feet per minute) measures how much air is being released from a compressor in one minute; this has a direct impact on the performance of your paint sprayer. Most HVLP guns require at least 2 CFM for proper operation.
5. Flow Meter:
Flow meters are used to measure the amount of air that is being released from a compressor. This helps you ensure you have adequate air flow while spraying, which will ultimately result in better finish quality.
6. Duty Cycle:
Duty cycle is an important factor when selecting an air compressor for HVLP spray gun, as it measures how long a compressor can run continuously before needing to rest and cool down. It’s generally recommended to look for a duty cycle rating of at least 70%.
7. Portability:
Portability is also an important factor when selecting an air compressor for HVLP spray gun, as it will determine how easy (or difficult) it is to move and transport the compressor. Generally speaking, smaller and lighter compressors are easier to move around than larger models.
By keeping these important factors in mind when selecting an air compressor for HVLP spray gun, you can ensure that your compressor provides enough pressure and volume to help improve the quality of your work while still being within budget.
Factors in Detail:
Now let’s discuss these 7 factors one by one in detail.
PSI Requirement for HVLP Spray Gun:
The PSI (pounds per square inch) required to run an HVLP spray gun with an air compressor depends on the type of HVLP spray gun being used. Generally speaking, gravity-feed HVLP guns require 8-10 PSI, siphon-feed HVLP guns require 10-12 PSI and turbine-powered HVLP guns require 15-20 PSI for proper operation.
CFM Requirement for HVLP Spray Gun:
The CFM (cubic feet per minute) required to run an HVLP spray gun with an air compressor depends on the type of sprayer being used and the size of the tank. Generally speaking, for a small tank (1-2 gallons) you will need at least 2 CFM; for a medium tank (4-6 gallons) you will need at least 4 CFM and for a large tank (8-10 gallons) you will need at least 6 CFM.
Horsepower Requirement for HVLP Spray Gun:
The HP (horsepower) needed to run an HVLP spray gun with an air compressor depends on the type of sprayer being used and the size of the tank. Generally speaking, for a small tank (1-2 gallons) you will need at least 1.5 HP; for a medium tank (4-6 gallons) you will need at least 2 HP and for a large tank (8-10 gallons) you will need at least 3 HP.
Tank Size Requirement for HVLP Spray Gun:
The tank size required to run an HVLP spray gun with an air compressor depends on the type of sprayer being used and the extent of your spraying tasks. Generally speaking, if you have simple projects that don’t require extensive spraying, then a small or medium tank (1-6 gallons) should suffice; however, if you have larger projects that require more spraying, then you should opt for a larger tank (8-10 gallons).
Flow Meter Requirement for HVLP Spray Gun:
A flow meter is a device used to measure the amount of air that is being released from a compressor in one minute. This helps you ensure you have adequate air flow while spraying, which will ultimately result in better finish quality. It is recommended to use a digital flow meter for maximum accuracy, as it will provide readings up to 0.1 CFM increments.
Duty Cycle Requirement for HVLP Spray Gun:
The duty cycle of an air compressor measures how long an air compressor can run continuously before needing to rest and cool down. For HVLP spraying projects, it’s generally recommended to look for a duty cycle rating of at least 70%.
Portability Requirement for HVLP Spray Gun:
Portability is also an important factor when selecting an air compressor for HVLP spray gun, as it will determine how easy (or difficult) it is to move and transport the compressor. Generally speaking, smaller and lighter compressors are easier to move around than larger models.
Why Do You Need An Air Compressor For HVLP Spray Gun?
You need an air compressor for a HVLP spray gun because it provides the necessary amount of pressure and volume to help improve the quality of your work.
