High-Speed Rolling Door Air Shower with HEPA 99.995% Filtration & Safety Sensors

The Rapid Rolling Door Goods Air Shower is a high-performance decontamination system designed for cleanroom entry/exit zones handling large-scale goods. It ensures compliance with ISO 14644-1 standards and integrates stainless steel door body structures, radar sensor control, and German-standard wind-resistant components to prevent cross-contamination between high/low clean areas. Ideal for pharmaceutical, food, and precision manufacturing industries, it features:

Stainless steel rapid rolling doors with safety electric eyes, adjustable speed (open: 0.6–2.5 m/s, close: 0.8–2.0 m/s), and segmented aluminum alloy wind rods for enhanced durability.

Double-sided air shower with 24 stainless steel nozzles (13–25 m/s wind speed), imported French polyester door curtain (0.8mm thickness, orange color, self-cleaning PVC coating), and horizontal PVC transparent window (1.2mm thickness).

Quadruple filtration: 4 primary filters + 4 HEPA filters (99.995% efficiency @ 0.3µm, DIN75200 certified), non-toxic base cloth, and weighted air barrier for dust-proof sealing.

Smart control: Microcomputer system with radar sensors, hand-press switches, voice prompts, and interlocking to prevent simultaneous door operation.

Key Features

1. Rapid Rolling Door System: Stainless steel construction with safety electric eyes, adjustable speed, and German-standard aluminum alloy wind rods for wind resistance.

2. High-Strength Door Curtain: French industrial polyester fiber with PVC coating (0.8mm thickness, tear resistance: 600N/600N, temperature range: -30°C to +70°C).

3. Smart Safety Controls: Radar sensors + manual switches, automatic reversal upon obstruction, and interlocking to prevent dual-door activation.

4. Advanced Filtration: Non-toxic, self-cleaning HEPA filters (99.995% @ 0.3µm) with segmented air barrier sealing.

5. Durable Sealing: Weighted bottom air barrier and rubber strips for dust/insect-proofing on uneven floors.

6. Energy Efficiency: 8 kW total power consumption with 4 high-performance fans.

Application Scenarios

Air Lock Function: Prevents unclean airflow between high/low clean areas during goods transfer.

High-Throughput Facilities: Warehouses, pharmaceutical production lines, and food processing zones requiring rapid decontamination.

FAQ 1: Will the high-speed door operation compromise air shower filtration efficiency?
Answer: No. The HEPA 99.995% filtration (certified to DIN75200) works independently of door speed. Even at maximum opening/closing speeds (0.6–2.5 m/s), the dual-sided nozzles maintain 13–25 m/s laminar airflow to remove 0.3µm particulates before entry.

FAQ 2: How reliable are the safety sensors in busy industrial environments?
Answer: The safety electric eyes use infrared photoelectric detection with <0.5s response time. If obstructions (people/objects) are detected during door closure, the system instantly reverses direction and raises the door, validated by 50,000-cycle durability testing.

FAQ 3: Does the HEPA system require frequent filter replacements?
Answer: With self-cleaning PVC-coated curtains and pre-filters capturing 90% of large particles, the HEPA filters only need replacement every 12–18 months under normal use, reducing long-term maintenance costs by 40% versus standard models.
