A "cordless spray gun 21V" refers to a battery-powered paint sprayer that uses a 21-volt lithium-ion battery system. These tools offer significant convenience and portability for painting projects, as they eliminate the need for power cords and air compressors.
Key Features and Specifications (Typical for 21V Cordless Spray Gun):
Voltage (21V): This is the battery's nominal voltage. It provides sufficient power for a wide range of painting tasks, from furniture to walls. (Note: sometimes marketed as "20V Max").
Battery Type: Almost exclusively Lithium-Ion (Li-ion).
Capacity (Ah): Battery capacity is crucial for runtime. Common capacities are 1.5Ah, 2.0Ah, or 3.0Ah. Many models come with two batteries to allow for continuous work while one charges.
Charging Time: Varies, but fast chargers can often charge a 2.0Ah battery in 1-3 hours.
Motor:
RPM: Typically a high-speed motor, often around 38,000 RPM, to ensure consistent atomization and a smooth spray pattern.
Spray Technology: Most 21V cordless spray gun use HVLP (High Volume Low Pressure) technology.
