Exact Specification Parameters

• Compatible Hose: Standard telescopic exhaust hose, inner diameter 100 mm
• Interface Design: The insertion section is precisely matched to a 98–100 mm diameter, ensuring a tight fit with no air leakage
• Main Body Outer Diameter: 109 mm, balancing structural strength with smooth airflow
• Magnetic Attachment System: Built-in 8×3 mm strong magnets (mounting hole dimensions 8.2×3.2 mm), providing secure adhesion and compatibility with common metal window screen frames

• ⚙️ Detailed Explanation of Key Features

• 1️⃣ Precise Sealed Connection
• The insertion section features a tapered design that gradually narrows from 98 to 100 mm, accommodating hoses within the specified tolerance range. Combined with annular ridges on the inner wall, this ensures a tight, leak-proof connection that prevents both air leakage and disconnection.
• 2️⃣ Magnetic Quick-Release System
• Four built-in strong magnets create a uniform magnetic field, allowing instant attachment to the metal frame on either side of the window screen. No drilling or tools are required, making it ideal for temporary ventilation needs—such as exhaust from 3D printers or cooling of temporary equipment.
• 3️⃣ Dual Fall-Protection Mechanism
• Rope-Attachment Hole Design: A Φ2 mm rope hole is provided on the side, enabling users to attach a supplied safety cord to the window frame or a hook for added security;
• Magnetic Attraction + Physical Fixation: The magnetic attraction bears the primary load, while the rope serves as a backup to prevent detachment in strong winds or accidental impacts.
• 4️⃣ Structural Detail Optimization
• Reinforced Bottom Ring: Enhances the interface’s resistance to deformation, extending the service life during repeated insertions and removals;
• 90° Fluid-Optimized Elbow: The outdoor elbow features a smooth, curved transition on the inner wall with fan-shaped guide vanes, reducing turbulence and noise; the outdoor elbow also incorporates fan-shaped guide vanes to improve exhaust efficiency.

• 🏠 Suggested Application Scenarios

• 3D Printing Workshops: Allows quick assembly and disassembly, providing flexible venting for printing fumes and fine particulates;
• Kitchens and Bathrooms: Offers temporary enhanced exhaust; magnetic attachment ensures secure positioning without damaging the window screen;
• Air Conditioner/Equipment Cooling: Provides a short-term airflow channel for outdoor units or cabinets;
• Laboratories and Workspaces: Addresses occasional emissions of smoke and dust.
