Suitable For Long-Term Use Siphon-Feed Pneumatic Spray Gun

Product Description

AB-17S

I. Product Positioning and Core Functions

AB-17S is a siphon-feed pneumatic spray gun. It is suitable for automotive repair, furniture painting, and industrial spraying scenarios. Its design may have the following features:

1.High atomization accuracy: By optimizing the air cap structure (such as the design of auxiliary vent holes), the uniformity of atomization is improved, reducing the sense of spray particles.

2.Flexible adjustment: Equipped with three-way adjustment knobs for coating flow rate, spray width, and air pressure, it can be adapted to different coating types (such as primer, topcoat, and high-viscosity coatings).

3.Lightweight design: The gun body is made of aluminum alloy (weighing approximately 0.5-1kg), reducing the fatigue during operation and suitable for long-term use. 

II. Technical Specifications (Reference to similar products and industry standards)

Feeding method: Siphon type (design with a lower pot), capacity approximately 1000ml, supports quick material change.

Nozzle diameter: Options available include 1.4mm, 1.7mm, 2.0mm, etc., suitable for different coating requirements (such as metal paint requires a smaller diameter, clear coat is compatible with a medium diameter).

Working pressure: Suggested to be adjusted to 0.45-0.55 megapascals (approximately 4.5-5.5 bar), to ensure the spray effect and spraying efficiency.

Spray width: Single spray coverage width is approximately 15-20cm, suitable for fine work on small to medium areas. 

III. Usage Methods and Operating Specifications

1.Preparations before spraying

Paint preparation: Dilute the paint according to the specified ratio (for example, the dilution rate of varnish is approximately 30%). Ensure the viscosity meets the "Paint-4 cup" standard of 17-24 seconds, and filter out impurities.

Spray pattern adjustment: Rotate the spray pattern adjustment screw. Clockwise rotation tightens it to a circular spray pattern, and counterclockwise adjustment makes it an elliptical wide spray pattern, suitable for different spraying requirements.

Pressure adjustment: Connect the compressed air source. The initial pressure is set at 0.45-0.55 megapascals. Through trial spraying, adjust it to the optimal state. 

2.Spraying Operation

Distance Control: Keep the spray gun at a vertical distance of 15-20 cm from the workpiece, move at a constant speed to avoid run-off or dry spraying.

Spraying Mode: First, lightly press the trigger to blow dust and clean the surface, then fully press the trigger to spray the coating. Apply it in multiple thin layers to enhance uniformity. 

IV. Common Problems and Solutions

Uneven atomization: Check for clogging of the air cap or excessive viscosity of the coating, and clean or adjust the dilution ratio.

Paint leakage and air leakage: Replace the worn-out sealing ring and apply lubricating oil during installation.

Flowing and dripping during spraying: Reduce the coating flow rate, shorten the spraying distance, or increase the moving speed. 

V.  Application Scenarios Recommendation

1.Automobile Repair: Small-area paint patching, detailed restoration (such as the edges of car doors, bumpers).

2.Furniture Painting: Wood finish spraying, it is necessary to control the spray area to avoid excessive diffusion.

3.Industrial Anti-corrosion: Combined with large-diameter nozzles (such as 1.7mm) for spraying anti-corrosion coatings to improve efficiency.

FAQS:

Question A:How to maintain and care AB-17S spray gun properly?

Answer A: Maintenance and Care Tips

1.Daily Cleaning

Clean the paint channels immediately after use with a diluent, focusing on cleaning the nozzles and air caps to prevent solidification blockages (especially for two-component paints).

Avoid using metal wires to clean small holes to prevent damage to the components and cause abnormal atomization. 

2.Lubrication and Inspection

Regularly apply lubricant to components such as needle valves and springs to maintain the flexibility of the sealing gaskets and prevent air and paint leakage.

Check the sealing performance of the gaskets and replace them promptly if any wear is detected to ensure the airtightness of the spray gun. 

3.Storage Suggestions

For short-term disuse, the gun tip can be immersed in the solvent, but avoid soaking the entire gun to prevent the sealing ring from aging.

For long-term storage, it is necessary to dry thoroughly and place it in a cool and dry place to avoid corrosion of components by strong acids and alkalis. 

Question B: How can the working pressure of the AB-17S spray gun be adjusted?

Answer B: The working pressure of the AB-17S spray gun can be adjusted as follows: 

1. Confirm the air source: Connect the air intake interface of the spray gun to the compressed air source that has been filtered by the oil-water separator. Ensure that the air pipe is securely connected. 

2. Locate the adjustment knob: Usually, there is an air pressure adjustment knob at the rear of the spray gun. Some spray guns may also be equipped with an air pressure gauge to allow for real-time monitoring of the air pressure. 

3. Initial adjustment: Based on experience, the working pressure of the AB-17S spray gun is generally between 2.0 - 3.5 bar (30 - 50 psi). You can first adjust the air pressure knob clockwise to reduce the pressure as needed, or counterclockwise to increase the pressure, and set the pressure to the approximate range. 

4. Spray Test Adjustment: Before the actual spraying, conduct a spray test on waste material to observe the atomization effect and spraying condition of the coating. If the coating does not atomize evenly, there is dripping or abnormal spray range, it indicates that the air pressure may be inappropriate. Continue to fine-tune the air pressure knob until the desired spraying effect is achieved. 

When adjusting, it is necessary to pay attention that the adjustment range should not be too large each time. You should adjust while observing, and at the same time ensure that the paint and the spray gun are compatible, that the paint has been thoroughly mixed and filtered, and that the spray gun has been cleaned. Only in this way can the appropriate working pressure be adjusted and good spraying quality be achieved.
