Product Specification
Centered on "low-pressure high atomization + multi-scenario adaptation + high efficiency & material saving", the YD32-001 HVLP Gravity Feed Spray Gun is optimized for different spraying needs. Its core advantages are as follows:
Compared with traditional high-pressure spray guns (60-80 PSi), this product's low-pressure design has significant advantages:
- Finer Atomization: 43 PSi low pressure combined with a split air cap improves the uniformity of atomized particles by 40%. After spraying, the coating thickness deviation is ≤5μm (e.g., no orange peel on furniture panels), eliminating the need for subsequent sanding and polishing, and reducing process costs;
- High Coating Utilization: HVLP technology increases coating adhesion rate to over 65% (only 40% for traditional spray guns). For example, when spraying a 1㎡ furniture panel (requiring 100mL of coating), this product can save about 25mL of coating, reducing material costs in long-term use;
- Environmental Protection & Low Pollution: Low-pressure atomization reduces coating scattering (paint mist reduced by 50%), and the VOC concentration in the working environment meets the national indoor air quality standard (GB/T 18883-2022), reducing health impacts on operators and eliminating the need for additional complex ventilation equipment.
Three types of stainless steel nozzles cover most spraying needs, eliminating the need to purchase dedicated spray guns separately:
- 1.4mm Fine Nozzle: Suitable for low-viscosity coatings such as water-based paint and clear coat, used for car scratch repair and fine spraying of furniture edges (e.g., carved parts of solid wood furniture). Spraying width ≤15cm, coating thickness can be controlled at 10-15μm;
- 1.7mm Regular Nozzle: Compatible with medium-viscosity coatings such as acrylic paint and nitrocellulose paint, used for large-area spraying of furniture panels and wooden doors. Spraying width 20-25cm, efficiency up to 8-10㎡/hour, balancing precision and speed;
- 2.0mm High-Viscosity Nozzle: Designed for thick primers and anti-rust paints to prevent nozzle blockage. Spraying thickness up to 30-40μm, suitable for anti-rust treatment of industrial parts (e.g., metal brackets), and one spray can meet anti-rust requirements.
- Large Capacity Reduces Frequency: A 600mL cup can meet the needs of 15-20㎡ regular spraying (e.g., one wooden door), eliminating frequent shutdowns for refueling. Compared with a 300mL small cup, work efficiency is increased by 50%;
- Visual Monitoring: The high-transparency PC cup allows real-time observation of coating remaining and stirring status, avoiding spraying interruptions due to insufficient coating or coating color difference due to sedimentation;
- Leak-Proof Sealing: Double sealing with threads and rubber gaskets ensures no liquid leakage even when the gun is tilted at 45° for spraying (e.g., furniture sides), avoiding coating waste and workpiece contamination.
- Lightweight Gun Body: The 850g aluminum alloy gun body (equivalent to the weight of a bottle of mineral water) causes no hand soreness even after 2 hours of continuous spraying, and can be easily operated by female users, solving the fatigue problem of traditional cast iron spray guns (over 1.2kg);
- Ergonomic Grip: The grip adopts an arc design that fits the palm curve. The trigger pressing force is only 3N (equivalent to lifting a 0.3kg object), and there is no pressure on the fingers during long-term operation;
- Easy Cleaning Design: The inner cavity of the gun is smooth without dead ends. After spraying, it can be cleaned by rinsing with a solvent (e.g., banana oil) for 30 seconds. The nozzle can be disassembled and cleaned separately to avoid coating residue blockage (traditional spray guns require disassembling more than 5 parts, which is time-consuming).
- Corrosion-Resistant Gun Body: The anodized aluminum alloy gun body can come into contact with most solvent-based coatings (e.g., epoxy primer), with no paint peeling or corrosion in long-term use, and its service life is 4 times that of plastic gun bodies;
- Wear-Resistant Nozzle: The 304 stainless steel nozzle has no thread slipping after 500 repeated disassembly operations, and no scratches on the inner wall, avoiding poor atomization caused by nozzle wear (the precision of traditional brass nozzles decreases after 100 uses);
- Durable Sealing: The cup gasket is made of solvent-resistant nitrile rubber, which remains elastic after 100 repeated uses, with no aging or liquid leakage, and no frequent replacement is needed (the accessory unit price is only 2 yuan, with low maintenance costs).
- Universal Air Source: The G1/4" interface can be connected to small household air compressors (≥0.3m³/min displacement) and industrial air compressors, eliminating the need to replace the spray gun due to air source specifications;
- Coating Compatibility: It can spray solvent-based coatings (e.g., nitrocellulose paint, polyurethane paint), water-based coatings (e.g., water-based wood paint), and high-viscosity coatings (e.g., thick anti-rust paint). Only the nozzle needs to be replaced and the gun body cleaned, with no need to purchase dedicated spray guns separately, saving equipment costs.
Scenario Requirement: A furniture factory sprays nitrocellulose topcoat on solid wood panels (1.2m×2.4m), requiring uniform coating (no orange peel) and high efficiency (30 panels per day on average). A 1.7mm nozzle and 43 PSi pressure are used, combined with a 0.5m³/min air compressor.
Operation Process:
- Preparation: Install a 1.7mm nozzle, pour nitrocellulose topcoat (diluted to a viscosity of 18-20s) into the cup (500mL), connect the air compressor and adjust to 43 PSi;
- Spraying Operation: Keep the gun distance at 20cm, spray the panel at a uniform speed of 40cm/s. The fan-shaped atomization covers a width of 25cm, with 50% area overlap. One panel only takes 2 minutes (2 coats of spraying);
- Cleaning & Maintenance: After spraying, rinse the gun body and nozzle with banana oil (taking 1 minute), and replace the cup gasket (check once every 10 panels).
Result: An average of 35 panels are completed per day (exceeding expectations), with a coating qualification rate of 98% (no sagging or missing spots). The coating utilization rate is increased to 68%, saving about 1.5L of coating per day compared with traditional spray guns, and saving more than 5,000 yuan in material costs annually.
Scenario Requirement: An auto repair shop repairs a car door scratch (area approx. 0.2㎡), using water-based touch-up paint (low viscosity), requiring fine spraying (no color difference, no particles). A 1.4mm nozzle and 40 PSi pressure (slightly lower than the standard 43 PSi for finer results) are selected.
Operation Process:
- Preliminary Preparation: Remove the old nozzle, install a 1.4mm nozzle, pour water-based touch-up paint (diluted to a viscosity of 15s) into the cup (100mL), connect a small air compressor and adjust to 40 PSi, test the atomization (narrow fan shape, width 15cm);
- Fine Spraying: First cover the surrounding area with masking film, keep the gun distance at 15cm, gently press the trigger at a speed of 20cm/s, and apply 3 thin coats (5 minutes of drying time between each coat) to avoid sagging;
- Subsequent Treatment: After spraying, rinse the gun body with clean water (water-based paint is easy to clean), and soak the nozzle in clean water separately to avoid blockage.
Result: The color difference between the repaired coating and the original car paint is ≤ΔE2.0 (invisible to the naked eye), with no particles or orange peel, and no subsequent sanding is needed. Customer satisfaction is increased by 90%, and the repair time is reduced from 1 hour with traditional spray guns to 30 minutes.
Scenario Requirement: A DIY enthusiast renovates an old wooden table (area approx. 0.8㎡), using water-based wood paint (environmentally friendly and odorless), a household 0.3m³/min small air compressor, and selects a 1.7mm nozzle, requiring simple operation and no professional skills.
Operation Process:
- Novice Operation: Install a 1.7mm nozzle according to the manual, pour water-based paint directly into the cup (no complex dilution, pre-adjusted viscosity by the manufacturer), connect the air compressor, and adjust the pressure to 43 PSi according to the manual;
- Easy Spraying: Hold the spray gun at a distance of 20cm, move uniformly along the wood grain of the table, and one coat can cover the surface (water-based paint has good leveling property), taking only 15 minutes in total;
- Simple Cleaning: Rinse the gun body with clean water for 30 seconds, scrub the cup directly without professional solvents, and store it in a toolbox after cleaning (volume only 30cm×15cm×10cm, no space occupation).
Result: The renovated wooden table has a smooth and uniform surface, with no missing spots or sagging. The water-based paint is environmentally friendly and odorless, and can be used on the same day, solving the pain points of novices "not knowing how to adjust pressure and clean", and realizing "good spraying even with zero foundation".
A1: It is mostly due to too low air pressure or too slow moving speed, which can be solved by targeted adjustment:
- Cause Investigation: ①Air pressure lower than 40 PSi (too large atomized particles, coating accumulation); ②Nozzle moving speed <20cm/s (too much coating per unit area); ③Coating not diluted (too high viscosity, poor fluidity);
- Solution: ①Adjust the air pressure to 43-45 PSi (adjust via the gun's pressure regulating valve, observe the atomization to form a uniform fan shape); ②Increase the moving speed to 30-50cm/s, keep it uniform (practice with a timer if necessary); ③Add 5%-10% clean water to dilute water-based paint, and 10%-15% thinner to solvent-based paint. Test with a viscosity cup after stirring (18-20s is appropriate);
- Precautions: For sagging coatings, sand them smooth with 400-mesh sandpaper after they are completely dry, then apply a thin coat again to avoid more serious sagging caused by direct coverage.
A2: Select based on coating viscosity and spraying needs. Wrong selection will lead to poor atomization or low efficiency:
- Selection Logic: ①1.4mm nozzle for low-viscosity coatings (water-based paint, clear coat) (fine atomization, avoiding waste); ②1.7mm nozzle for medium-viscosity coatings (nitrocellulose paint, acrylic paint) (balancing precision and efficiency); ③2.0mm nozzle for high-viscosity coatings (primer, anti-rust paint) (avoiding blockage, ensuring flow rate);
- Impacts of Wrong Selection: ①Using a 2.0mm nozzle to spray water-based paint: coarse atomized particles, granular coating, and 30% increase in coating waste; ②Using a 1.4mm nozzle to spray primer: insufficient flow rate, requiring 5-6 more coats to reach the required thickness, and 80% decrease in efficiency;
- Suggestion: Novices can first purchase a 1.7mm nozzle (most versatile), and then supplement with 1.4mm or 2.0mm nozzles according to needs (single nozzle has a low unit price, no need to buy all at once).
A3: Leakage is mostly due to improper installation or gasket problems, which can be solved by step-by-step inspection:
- First Step: Check Installation: Confirm whether the threads of the cup and gun body are tightened (rotate clockwise until it cannot move). If not tightened, coating will leak from the thread gap, and it can be solved by re-tightening;
- Second Step: Check the Gasket: If leakage still occurs after tightening, remove the cup and check whether the gasket is deformed, cracked, or has foreign objects (e.g., coating residue). ①Deformation/cracking: Replace with a new gasket (original accessories have strong adaptability, avoid using non-original gaskets with incorrect sizes); ②Foreign objects: Wipe clean with a cotton swab dipped in solvent and reinstall;
- Preventive Suggestion: Check the gasket status before adding coating each time; avoid scrubbing the gasket with a hard-bristle brush when cleaning the cup to prevent wear and extend its service life.
A4: A 0.2m³/min air compressor can be used for short-term use. For long-term use, it is recommended to use ≥0.3m³/min to avoid unstable air pressure:
- Short-Term Use (e.g., DIY small-area spraying): A 0.2m³/min air compressor can support 1.4mm or 1.7mm nozzles. When spraying, attention should be paid to: ①Continuous spraying for no more than 3 minutes at a time (to avoid air compressor overload); ②Fill the air compressor's pressure tank in advance (to 0.8MPa) and use the pressure tank to stabilize the pressure, reducing air pressure fluctuations;
- Long-Term Use (e.g., more than 1 hour per day): It is recommended to replace with an air compressor of 0.3m³/min or more. Because the displacement of a 0.2m³/min air compressor is insufficient, the air pressure will frequently drop below 40 PSi, resulting in poor atomization (granular coating), and frequent start-stop of the air compressor will shorten its service life;
- Adaptation Suggestion: Check the "displacement" parameter (not volume) of the air compressor before purchasing. 0.3m³/min can meet the needs of all nozzles of this spray gun, and there is no need to pursue high power (saving electricity costs).
