This summary focuses on Hongfa's high-speed doors specifically designed for cleanroom environments. It details product models tailored to different cleanliness requirements and outlines key selection factors. It serves as a practical reference for industries like pharmaceuticals, food processing, and electronics in choosing the right products.
I. Core Product Models & Features
1. Standard PVC High-Speed Door (Brush Seal Type): Features high-quality PVC curtains paired with standard brush seals. Ideal for areas with moderate cleanliness requirements, including general electronics assembly zones, cleanroom buffer areas, and packaging workshops with basic dust control needs. This model offers excellent cost-effectiveness, suitable for large-scale deployment across multiple low-to-moderate cleanliness areas. Its modular design enables quick on-site installation, and minimal moving parts reduce maintenance frequency and costs. Stable high-speed operation helps minimize air exchange between zones.
2. Zipper High-Speed Door: An enhanced version of the standard model, achieving significantly better sealing through an integrated "zipper" curtain design—where the curtain edges interlock tightly with the door frame to eliminate gaps that could allow dust or microorganism infiltration. Well-suited for areas with moderately high cleanliness requirements, such as precision component manufacturing workshops, food processing intermediate zones, and pharmaceutical secondary packaging areas. Advantages include superior airtight sealing to block external dust, particles, and microorganisms; enhanced durability due to reduced friction between curtain and frame (extending service life in high-frequency use); and adaptability to moderate humidity and temperature fluctuations in industrial cleanroom environments.
II. Key Selection Considerations
1. Match Sealing to Cleanroom Class: Choose brush seal for moderate levels, zipper design for medium-high levels, and premium C-shaped guide design for high levels.
2. Industry-Specific Needs: Pharmaceuticals & Food Processing: Prioritize corrosion-resistant materials (e.g., 304 stainless steel) and GMP compliance.
Electronics: Focus on static control (with optional anti-static curtains) and particle containment.
3. Usage Frequency: High-frequency operation (e.g., busy production lines) requires doors with durable drive systems and wear-resistant curtains for long service life.
4. Operational Safety: Consider features like safety sensors (to detect obstacles) and transparent curtains (to improve visibility) to minimize workplace accidents.
5. Maintenance & After-Sales Service: Choose models with simplified maintenance needs and a reliable after-sales support system to reduce downtime.
