Spray Finishing Technology & Definitions

Transfer Efficiency
Transfer efficiency rates the spray painting equipment's ability to put material on the target, compared to how much escapes as over-spray bounce back material. Transfer efficiency relates directly to material savings and environmental compliance.

Flow Rate
Flow rate is the volume of material that can effectively be atomized through an applicator. It is typically referred to in ounces per minute (oz./min.) or grams per minute (g./min).

HVLP - High Volume Low Pressure -- Delta Spray
HVLP is controlled air spray technology that limits the air pressure in the air cap in order to reduce the bounce back and over spray. HVLP is used on wood and metal finishing and touch up applications utilizing up to 10 psi. atomizing air pressure and fluid pressures in the range of 5- 20-psi.

Electrostatic Spray Technology
Graco Pro xS electrostatic technology may be used in air spray, air - assisted and airless spray methods. The Electostatic process greatly reduces over-spray and greatly saves time while spraying. Electrostatic charged coatings wrap the part being coated making it easier to coat a part. Material and Labor Savings pay for the electrostatic gun - We would be happy to calculate your cost savings with electrostatic guns.

Air-Assisted Airless - Alpha & Alpha Plus
Air-Assisted atomization is a hybrid application method that combines the hydraulic atomization method of airless with the atomization of air spray. The result is an atomization level between air spray and airless. This process is ideal for many finishing and coating applications that require high production levels and a smooth finish, such as wood furniture topcoats, fabricated metal parts, and farm and construction equipment. Air-assisted atomization typically utilizes air pressures up to 35 psi. and fluid pressures range from 250-4000 psi. at the gun.

Airless - Silver Plus
Airless atomization is accomplished by directing fluid under high pressure through a controlled orifice. Airless works best when used to quickly apply high volumes of coatings to large surfaces, such as bridges, storage tanks, or large sheets of metal. Airless is most often used to apply protective, rather than decorative coatings. Typical Fluid pressures are up to 5000 psi. at the gun.
