Feed Hvlp
what is the difference between a conventional spray paint gun and a HVLP spray gun.?

is the conventional the one that has the cup on the bottom and the hvlp Self Feed on top.

they are two different technologies. the conventional spray gun ejects a high pressure mist onto the intended surface, and it usually results in a high quality, aesthetically pleasing finish. the problem with conventional spray guns is that only 30% of the finish (whatever you are applying to the surface) actually ends up where you want it. the rest of the finish will be released into the atmosphere. this obviously wastes time and material. this is actually very harmful for the environment and the use of conventional spray guns is restricted in many jurisdictions because of this.

the HVLP spray guns are a newer, more efficient technology. there are actually 2 types of HVLP spray guns; one is compressor based, while the other works off of a turbine. the compressor variation is useful for people who already own an Air Compressor and it delivers good results. the turbine version is actually more desirable due to the fact that it delivers a much higher volume of air when compared to its compressor counterpart. this results in a higher quality finish and more efficient use of finishing material.

Want to Spray Paint Your Own Car? - Discover All the Spray Painting Techniques You Can Use

Each and every spray systems is made up of three crucial parts: a compressor to pressurize the paint, a container to hold the material and a spray gun to spread it across the required surface through its nozzle in a fine mist. The process of painting by use of compressed spray gun is very simple. On pressing the trigger switch, Ventury effect gets formed, and the paint combines with the Compressed Air releases itself into the surface as a fine mist.

Different spray painting techniques are employed to paint the surface of a car and all of them use compressed air or fluid or Air Pressure to discharge and direct the spray. Spray guns are commonly used for spraying cars. Spray guns have two main classifications: suction fed and gravity fed. Both are easily identifiable from its shape and the way it is arranged.

In suction fed spray guns, the paint container is fixed below the Air Gun and compressed air is used to attain the desired spread. It also has a dedicated air cap to generate low vacuum. In gravity fed, the container is at the top of the gun and the major force acting on the system is gravity though compressed air is used to a lesser extent. Gravity fed spray guns are capable of giving good performance than suction fed guns, as it uses less compressed air and has less weight.

Another process is the HVLP or High Volume Low Pressure system. Though akin to spray guns as far as the compressed air is concerned, the gun works at low pressure. The effect is that wastage is minimized to a large extent.

High Volume Low Pressure technology is used by professional refinishers and painting contractors. HVLP technology is where the turbine motor feeds a high volume of air through a spray gun at very low pressure. This gently forces the paint out of the gun and atmoizes the paint at the nozzle rather than blast it out like an airless. The continual airflow through the aircap acts likes a jacket or force field keeping the spray confined. This gives you greater control of the spray and makes it much easier to achieve a high quality finish with very little experience or skill.

A third process uses Low Volume Low Pressure or LVLP system, and is an improvement of the HVLP system of painting. Here wastage is further controlled and the intended surface gets more paint. Both HVLP and LVLP system need High Capacity compressors and may not be ideal for every day use.

In Electrostatic Spray painting, paint powder is used in this technique. When the paint is discharged from the gun, it is so arranged that it develops an electrostatic charge and is sprayed to the oppositely charged surface. As the minute paint particles repulse each other, the area covered by the paint is much more than other systems.

It is important to adhere to safety norms as fine mists of paint are formed and gets released into the air.

The Environmental Protection Agency has warned that chemical vapors released from paint and many other household products "may have short- and long-term adverse health effects." According to the EPA, exposure to these gases, known as volatile organic compounds (VOCs), may cause eye, nose and throat irritation; headaches and nausea. Studies suggest that long term exposure may result in liver, kidney, or central nervous system damage. VOCs can come from thousands of household products, including cleaning supplies, craft materials, glue, permanent markers.

No one is sure what level of VOCs is safe. For paints, the government has capped VOC levels at 250 grams per liter for flat finish paints and 380 grams for other finishes. Some agencies are setting much lower levels as their standards. In light of the possible risks, it seems prudent, especially for those with asthma or allergies or other risk factors, to keep exposure to VOCs to a minimum whenever possible.

VOCs are released during application of paints and for years afterward from the paint on walls and ceilings. VOCs have been found indoors in concentrations up to ten times higher than outdoors. Many people, concerned about exposure to VOCs, have turned to products with lower VOC levels. Fortunately a great number of low-VOC and zero-VOC paints are available from most leading paint companies. Using these paints not only reduces health risks, but also decreases unpleasant odors and air pollution. Fortunately the cost of these environmentally friendly paints is usually comparable to traditional paints.

One way to check for paints that are low in VOCs is to look for the Green Seal. Green Seal, an independent, science-based environmental certification agency, certifies products which it has tested and found to be eco-friendly. The 2010 Green Seal standards for paint include the requirement that it contains less than 50 grams of VOC per liter for flat finishes and less than 100 grams for primers and non-flat finishes before colorants are added. Colorants are added after VOCs are measured and may add as much as 50 grams per liter, although usually much less. Paints in these ranges are referred to as Low-VOC. The Green Seal further indicates that the paint does not contain a number of other toxic chemicals. Some paints, which also may have the Green Seal, contain less than 5 grams per liter and are known as Zero-VOC. Natural paints, a third category, contain no VOCs.

Another certification program is overseen by Greenguard Environmental Institute, an industry independent testing organization. Their Greenguard certification indicates that paints have met their stringent standards for VOC emissions.

Below is a sample of some of the more popular paint manufacturers and their eco-friendly paints. There are many other excellent low and zero VOC paints on the market. Check the paint can label to find its VOC levels.

Natural paints, as their name indicates, are made from natural ingredients such as plant oils and resins, plant dyes, bees wax, and minerals such as chalk and clay. They are generally considered the safest for the environment, but may not provide the coverage and durability many people expect. Among popular brands are Green Planet Paints, Ecos Organic Paints (in the United Kingdom), Eco Design's BioShield, and Real Milk Paint Company.

How Painters Can Reduce VOC Levels

The EPA has outlined a number of ways that painters can reduce the release of VOCs during the painting process:

1. Use water base paints and products that contain a higher amount of solids.

2. Use proper spraying equipment, such as high-volume, low-pressure (HVLP) sprayers, and spraying techniques that use less paint and therefore release fewer VOCs.

3. Store paint in airtight containers and only open them when in actual use.

4. Use cleaning techniques that minimize release of contaminants, such as re-using cleaning solvents, starting painting with light colors and moving toward darks to reduce the amount of cleaning needed between colors.

Choosing paints low in VOCs and following EPA guidelines while applying these paints can greatly reduce the levels of harmful vapors in your house, make it easier to move back into a room soon after painting, and improve the environment.
