It is sutiable for spray pre-treatment tunnel, industrial washing booth, automated coating line pre-treatment, phosphating tunnel, silane treatment system.

Engineered for seamless integration with continuous automated coating lines. Eliminate oil, rust, and contaminants to achieve superior adhesion and unparalleled corrosion resistance.

Product Overview

The foundation of any world-class finish is impeccable surface preparation. Our Automatic Spray Pre-Treatment Tunnels are robust, continuous-flow washing systems designed to clean and chemically treat metal and plastic components prior to powder coating or liquid painting.

Designed to operate seamlessly with overhead suspension chains and Power & Free Conveyor systems, these tunnels utilize high-density, targeted spray zones to execute multi-stage processes including degreasing, rinsing, phosphating, and silane treatments.

Core Advantages & Features

1.360° Precision Coverage: Equipped with adjustable, quick-release ball nozzles strategically positioned to eliminate blind spots and ensure total chemical contact on complex workpieces.

2.Heavy-Duty Corrosion Resistance: The entire tunnel body, internal piping, and recirculation tanks are constructed from premium SUS304 or SUS316 stainless steel, ensuring a long operational lifespan even with harsh chemical agents.

3.Eco-Friendly Fluid Recirculation: Features cascading multi-stage chemical tanks with double-layer stainless steel filtration systems. This drastically reduces water consumption and chemical waste.

4.Vapor & Thermal Control: Integrated centrifugal exhaust fans at both the entrance and exit silhouettes prevent chemical vapors and steam from escaping into your factory environment.

5.Maintenance-Friendly Design: Fitted with heavy-duty FRP (Fiberglass Reinforced Plastic) floor gratings to provide a safe, anti-slip walkway for operators during routine inspection and nozzle maintenance.

Frequently Asked Questions (FAQ)

Q1: What types of materials and processes is this downdraft table suitable for?
A: This workstation is highly versatile and ideal for capturing dust from sanding, grinding, and deburring metals, woods, and composites. It is also highly effective for capturing fumes and overspray during small-batch liquid painting or coating preparations.

Q2: Is the built-in lighting safe to use around flammable paint fumes?
A: Yes. The workstation is equipped with an explosion-proof lighting fixture, specifically designed to safely illuminate the work area without risking ignition in environments where flammable fumes or dust may be present.

Q3: How difficult is it to clean and maintain the work surface?
A: Maintenance is exceptionally straightforward. The entire unit, including the heavy-duty grated work surface, is constructed from smooth stainless steel, allowing for rapid wiping and cleaning. The integrated air blow gun also assists in keeping the grates clear of debris during operation.

Q4: Can this unit be integrated into an existing exhaust system?
A: Yes, the downdraft table can be configured as a standalone unit with integrated filtration, or it can be manufactured to connect directly to your facility's central dust collection or ventilation system.

Q5: Does it require any special installation?
A: It features a "plug-and-play" design for standard operations. Once positioned on your workshop floor, it requires standard industrial electrical connections and a compressed air line for the blow gun accessory. No complex structural installation is necessary.
