Product Specification
Centered on "efficiency improvement for bulk spraying + adaptation to high-viscosity coatings", YD32-007 is optimized for the needs of medium-to-large area, high-volume spraying, with core advantages as follows:
Compared with small-caliber spray guns at the same price, the large-caliber design of this product is more suitable for bulk operations:
- 1.8mm for Medium Viscosity: Compatible with wall latex paint, furniture primer, etc., with a spraying width of 28-35cm and efficiency of 15-18㎡/hour (only 1.5 minutes for a 20㎡ wall). It provides uniform atomization without brush marks, meeting basic aesthetic and protective needs;
- 2.0mm for High Viscosity: Designed for anti-rust paint and thick-paste industrial paint, with a spraying width of 35-40cm. The coating flow rate is 25% higher than that of the 1.8mm nozzle, and the single-coat thickness reaches 30-40μm (e.g., anti-rust spraying for hardware brackets). No repeated application is needed, improving efficiency by 60% and avoiding the trouble of frequent clogging and repeated needle unclogging of small-caliber nozzles.
The brass nozzle has moderate hardness, avoiding thread slipping during assembly and disassembly. Even with frequent replacement (e.g., switching from primer to anti-rust paint), the thread remains intact. Compared with plastic nozzles, it has stronger wear resistance against high-viscosity coatings, extending the service life by 2 times. Cleaning only takes 1-2 minutes with thinner, no complex disassembly of components required, reducing maintenance costs.
Compared with 600mL cups, the 1000mL cup reduces refueling frequency by 60%—only one refuel is needed to spray 10 wooden doors (2.5㎡ each), avoiding efficiency loss caused by frequent shutdowns and material pouring. The high-transparency design allows real-time observation of remaining coating, enabling advance preparation for refueling, which is especially suitable for "tight-schedule" scenarios such as decoration projects and factory production.
Suction feeding uses air pressure to draw coating from the cup bottom to the nozzle. Even if the gun is tilted at 90° (e.g., spraying wall tops or fence sides), the coating will not flow back and clog the gun, making it more suitable for complex-angle spraying than gravity feed cups. The suction tube at the cup bottom can be adjusted freely, and the remaining 10% coating in the cup can still be normally sucked, reducing waste (coating utilization rate is 10% higher than that of traditional suction feed spray guns).
The 50 PSi pressure does not require an industrial-grade air compressor; a small household air compressor with 0.3m³/min displacement can drive it, avoiding the burden of "additional equipment investment after buying the gun". Compared with high-pressure spray guns (above 60PSI), its atomization is gentle, and beginners are less likely to cause sagging and paint mist splashing. Compared with low-pressure spray guns (≤40PSI), its efficiency is increased by 40%, completing 25㎡ wall spraying per hour.
The pressure regulating valve of the gun is easy to operate—just rotate the knob to adjust the pressure (45-55 PSi) without professional knowledge. Even if the air pressure of the air compressor fluctuates slightly (e.g., start-stop of household compressors), the built-in pressure regulating valve can maintain stable output. Beginners can complete qualified spraying by referring to the manual, lowering the threshold for bulk operations.
Scenario Requirement: A decoration team sprays water-based latex paint (medium viscosity, selecting 1.8mm nozzle) on 10 residential units in a new community (80㎡ wall area per unit) with a 0.4m³/min air compressor at 50 PSi pressure, pursuing high efficiency and low cost.
Operation Process:
- Preparation: Install the 1.8mm nozzle, pour latex paint (800mL per cup), adjust air pressure to 50 PSi, and test atomization (32cm wide fan shape with uniform particles);
- Spraying: Divide into 3-person groups—one person is responsible for spraying (25cm nozzle distance, 50cm/s speed, continuous operation in sections), one person for refueling and masking, completing 35㎡ per hour;
- Cleaning: Rinse the gun body and suction tube with clean water daily (water-based paint is easy to clean, taking 3 minutes), and store after drying.
Result: 10 residential units are completed in 3 days (including preparation time), with uniform coating and no brush marks. The coating utilization rate is 62% (20% higher than that of rollers), saving 1,200 yuan in project labor costs.
Scenario Requirement: A hardware factory sprays anti-rust paint (high viscosity, selecting 2.0mm nozzle) on 100 metal brackets (0.8㎡ each) with a 0.35m³/min industrial air compressor at 50 PSi pressure, requiring fast and up-to-standard results.
Operation Process:
- Preparation: Install the 2.0mm nozzle, pour anti-rust paint (700mL per cup), adjust air pressure to 50 PSi, and test atomization (no agglomeration);
- Spraying: One person operates, with 30cm nozzle distance and 60cm/s speed, taking 1 minute per bracket (one coat coverage);
- Cleaning: Rinse the gun body and nozzle with anti-rust paint thinner (taking 2 minutes), and soak the suction tube to prevent drying and hardening.
Result: 100 brackets are completed in 2 hours (3.5 hours with traditional spray guns), with anti-rust paint thickness of 35μm (meeting industry standards). The product qualification rate is 100%, and the cost of a single gun is only 1/4 of that of industrial-grade spray guns.
Scenario Requirement: A DIY user renovates a 20m×1.5m wooden fence (30㎡) by spraying outdoor weather-resistant paint (medium viscosity, selecting 1.8mm nozzle) with a 0.3m³/min household air compressor, for beginner operation.
Operation Process:
- Preparation: Install the 1.8mm nozzle according to the manual, dilute the weather-resistant paint to 20s viscosity, pour into the cup (600mL), adjust air pressure to 50 PSi, and test atomization on a waste wood board;
- Spraying: Keep 25cm nozzle distance, move uniformly along the fence. One cup of paint covers 5㎡, with a total of 6 cups of paint and 1.5 hours of operation;
- Cleaning: Rinse the gun body with thinner (2 minutes), scrub the cup and store.
Result: The fence has uniform color and firm adhesion of weather-resistant paint. Beginners succeed in the first operation, with a total cost of 300 yuan (saving 90% compared to hiring a professional team).
A1: It is mostly caused by wrong nozzle selection, blocked suction tube, or low air pressure. Solve it step by step:
- Replace the nozzle: High-viscosity paint requires a 2.0mm nozzle; using a 1.8mm nozzle will cause uneven output due to insufficient flow;
- Unclog the suction tube: Disassemble the suction tube, soak it in thinner for 15 minutes and rinse, or use a dedicated needle to unclog it (do not scratch the silicone tube);
- Adjust air pressure: Increase the air pressure to 50-52 PSi to enhance suction and ensure stable feeding;
Prevention: Stir high-viscosity paint for 5 minutes before use to avoid sedimentation; clean the suction tube within 1 hour after spraying.
A2: Solve it with "split cup storage + accessory adaptation":
- Split cup storage: Use a 300mL small measuring cup to dispense paint (only 20mL needed for 0.2㎡), and store the remaining paint in a sealed container in a cool place (solvent-based paint can be stored for 1 week, water-based paint should be used within 3 days);
- Add a capacity-reducing liner: Contact the merchant to purchase a 300mL plastic liner dedicated to 1000mL cups, which can be directly placed in the cup to reduce the coating storage space without affecting feeding;
Operation: Tilt the gun at ≤45° during small-area spraying to ensure the suction tube can absorb the paint in the liner.
A3: It is mostly caused by poor sealing or detached suction tube. Troubleshoot quickly:
- Check sealing: A loose cup lid will leak air pressure; rotate it clockwise until a "click" sound is heard (sealed in place). If the sealing ring is deformed, replace it with an original accessory;
- Check the suction tube: Open the cup lid, re-fix the suction tube (ensure it is attached to the cup bottom). If the tube is bent, straighten it;
Emergency: If no spare sealing ring is available, apply a thin layer of petroleum jelly on the surface of the sealing ring, which can be used temporarily for 2-3 times.
A4: A 0.25m³/min air compressor can only be used for small-area emergencies; ≥0.3m³/min is required for large-area spraying:
- Small-area emergency (e.g., one metal bracket): Use the "40s spraying + 20s pause" intermittent mode to avoid air pressure dropping below 48 PSi;
- Large-area spraying (e.g., walls, bulk hardware parts): Replace with an air compressor of ≥0.3m³/min. Otherwise, unstable air pressure will cause poor atomization and uneven coating, and frequent start-stop of the compressor will shorten its service life;
Suggestion: When choosing an air compressor, prioritize models with "air tank ≥20L" to stabilize air pressure and ensure spraying effect.
