K3 Paint Spray Gun

About the K3 paint gun, the following is a comprehensive information summary for your reference:

1.Common models and brands

Brand examples:

Domestic/OEM models: Some manufacturers may use "K3" to check specific parameters.

2.Core parameters

Spraying technology: high-pressure airless, HVLP (high flow low air pressure) or conventional air spraying.

Nozzle caliber: usually 1.2-1.8mm (affects paint flow and atomization effect).

Pressure range: approx. 150-250 bar for airless spraying, approx. 0.7-2 bar for HVLP.

Flow Regulation: High-end models support real-time adjustment of paint and air volume.

3.Application scenarios

Home Decoration/Wood: Suitable for latex paint, varnish.

Car refinishing: high-precision metallic paint, primer spraying.

Industrial Coating: Requires high-flow, wear-resistant spray guns, possibly with automatic control systems.

4.Precautions for use

Maintenance: Clean the nozzle with solvent after each use to avoid coating curing and clogging.

Safety: Wear a protective mask (against organic vapors) to ensure ventilation.

Debugging: Test the atomization effect on the waste material before formal spraying, adjust the air pressure and distance (usually 15-20cm).

5.Purchasing suggestions

Clarify the needs:

Small area repairs→ choose HVLP (paint saving, low rebound).

Airless spraying → large areas of walls (high efficiency, but masking protection)

Here are some frequently asked questions (FAQs) about the K3 Paint Gun:

How to install the hood and nozzle correctly？

Tighten the hood, usually from the beginning of the screw to half a turn, about 13 to 15 half turns is the best state, the hood should be parallel to the nozzle inside or a little more than a little bit, so that the spray is more normal.

How to adjust the air pressure and flow rate of the spray gun？

The air pressure adjustment knob and flow adjustment knob are generally screwed to a minimum of about 8 to 10 half turns. When spraying a small spray, the air pressure is adjusted to 3 to 5 turns, and the flow switch is adjusted to 1 to 2 turns; During the injection, the flow switch is adjusted to about 5 turns, and the air pressure is adjusted to 3 to 4 turns; During test spraying, the air pressure and flow switches can be close to the maximum, adjusted to about 8 to 9 turns.

What are the precautions before use？

When connecting the oil cup to the spray gun interface, you need to use a wrench to clamp the hex screw of the oil cup to avoid slipping teeth at the gun body interface. When the gun is connected to air pressure, never point the muzzle at anyone. Rinse the gun thoroughly with thinner before use to remove the rust inhibitor from the factory.

How to avoid nozzle clogging？

 Always clean the oil cup and spray gun paint channel after each day's work. It is strictly forbidden to use hard objects to clean the air holes and nozzles of the spray gun to avoid damage to the nozzles. In addition, the paint should be filtered before use to prevent impurities from entering the spray gun.

What coatings can be used？

The K3 paint spray gun can be used to spray corrosives, glazes, paints and varnishes, and other fluids, but not frosted, acidic, or gasoline-containing raw materials.

How to maintain the gun body？

Regularly lubricating the needle, needle sleeve and adjustment knob to ensure the flexibility of the gun. It is strictly forbidden to soak the spray gun in acidic and alkaline solutions to avoid corrosion and damage to the gun body seal.
