1. Working Principle:
The water curtain cabinet for painting operates by utilizing a water curtain to trap and filter paint mist and exhaust gases emitted during the painting process. As the spray gun releases paint, the water curtain within the cabinet intercepts the mist and odor, mixing with it through membrane effect and water viscosity to separate paint particles from the air, allowing them to settle into the water tank.

2. Structural composition:
Composed primarily of a pool, water curtain plate, top and side plates, water circulation system, and exhaust system, the water curtain cabinet is designed to function seamlessly. The pool collects paint mist and wastewater, while the water curtain plate forms a consistent barrier. The top and side plates form the cabinet's structural framework. The water circulation system maintains continuous flow, and the exhaust system vents filtered air externally.

3. Environmental & Safety Benefits:
The water curtain cabinet minimizes the environmental footprint of painting operations by preventing the dissemination of paint mist and exhaust gases beyond the workspace. Its water circulation system achieves a waste paint removal rate exceeding 99%, drastically lowering environmental impact. Additionally, it safeguards the health of operators.

4. Materials & Durability:
Crafted from stainless steel and coated with electrostatic paint, the cabinet body boasts excellent corrosion and rust resistance. The water tank and overflow tank, constructed from stainless steel plates, further ensure the cabinet's durability and stability.

Capacity Alignment: Ensure the water curtain cabinet's exhaust treatment capacity, including air volume and filtration efficiency, matches your workshop's painting operation scale.
Operational Simplicity: Select a cabinet that is straightforward to operate and maintain, facilitating quick staff adoption and routine maintenance.
Safety Compliance: Verify the cabinet's design adheres to safety standards, incorporating robust electrical safeguards and a stable structure.
Environmental Compliance: Confirm the cabinet meets local emission standards, guaranteeing effective air purification.
Brand Reliability: Choose a reputable brand with comprehensive after-sales service for prompt technical and maintenance support.
Material Durability & Quality: Opt for corrosion-resistant materials and high manufacturing standards to ensure long-term operational stability.
Process Suitability: Tailor your cabinet selection to fit your product type and painting process.
Energy Efficiency: Consider the cabinet's energy consumption and opt for high-efficiency models to minimize operational expenses.
Future Scalability: For potential capacity increases or process changes, select an expandable cabinet for flexibility.
Cost-Effectiveness: Balance your budget with long-term operating costs to select a financially prudent product.
1. Preparation
(1)Verify correct installation and functionality of the water curtain cabinet's components: 
(2)chamber body, water tank, water curtain plate, water circulation, and exhaust filtration systems.
(3)Confirm accurate power and water connections for smooth operation.
(4)Fill the water tank with adequate water and add paint coagulant as required for enhanced residue removal.
2. Operation Steps
(1)Position the workpiece on the workbench.
(2)Spray the workpiece using a handheld or fixed spray gun.
(3)Excess paint mist is captured by the water curtain and further refined through multiple layers.
(4)Purified air exits via the gas-water separator, while waste paint settles in the water tank.
3. Maintenance & Cleaning
(1)Regularly inspect and clean the water circulation system to maintain water clarity.
(2)Remove floating paint residue with a container for disposal.
(3)Replace water in the tank periodically to sustain purification effectiveness.
(4)Clean the spray gun and associated equipment to prevent clogging and ensure spray quality.
4. Safety Measures
(1)Operators must wear protective gear, including glasses, gloves, and masks.
(2)Pre-check fan rotation direction for effective exhaust discharge.
(3)Adhere to all safety protocols to ensure a secure workspace.
5. Shutdown & Maintenance
(1)Power down all equipment after use and conduct daily maintenance checks.
(2)Shut down immediately for inspection and repair if any equipment anomaly is detected.
