Rayshen Air Showers - Advanced Contamination Control for Cleanroom Entry
Rayshen Air Showers are specially engineered to remove surface contaminants from personnel and equipment before entering cleanroom environments. Designed to meet the strict cleanliness standards of industries such as pharmaceuticals, biotechnology, electronics, and food processing, these units ensure a critical first line of defense against airborne pollutants.
Utilizing high-velocity air nozzles (18-22 m/s) positioned at multiple angles, the system delivers a concentrated blast of clean air that dislodges dust, fibers, and particulates from clothing and exposed surfaces within just a few seconds. The powerful airflow is evenly distributed through dual fan systems, ensuring complete coverage and consistent performance.
Advanced features include electronically interlocked doors that prevent simultaneous opening, maintaining positive pressure and ensuring that unfiltered external air cannot enter the cleanroom area. This secure system supports cleanroom protocols and minimizes the risk of contamination during personnel entry or exit.
Constructed with a durable cold rolled steel body finished with electrostatic powder coating and fitted with stainless steel interior panels, Rayshen Air Showers are corrosion resistant, easy to clean, and built for long term performance.

Industrial Air Showers: High-Performance Cleanroom Entry Systems by Rayshen
Advanced Air Showers for Contamination Control & Cleanroom Integrity
In modern manufacturing, the human element is the largest source of particulate contamination. At Rayshen, we engineer high-velocity Air Showers that serve as a critical pressurized gateway between non-classified and sterile environments. Our systems are designed to "scrub" surfaces using HEPA-filtered air, ensuring that your cleanroom remains compliant with ISO 14644-1 and WHO-GMP standards.
Whether you are managing a pharmaceutical sterile filling line, a semiconductor wafer fab, or a high-security biocontainment lab, a Rayshen Air Shower is your first line of defense against product spoilage and batch failure.
What is a Cleanroom Air Shower?
An Air Shower is a self-contained, specialized antechamber that utilizes high-pressure air to remove dust, lint, and other contaminants from personnel or objects before they enter a clean zone. It acts as a "buffer" that prevents the migration of dirty air into the sterile workspace.
By creating a localized "wind tunnel" effect, our air showers dislodge microscopic particles trapped in the fibers of cleanroom garments. The air is then continuously filtered through a dual-stage system (Pre-filters and HEPA filters) to maintain a sterile cycle.
Key Features of Rayshen Air Showers
1. High-Velocity Air Jet Technology
Rayshen units are equipped with adjustable stainless steel nozzles that deliver air at velocities of 22 m/s to 30 m/s. This specific velocity range is engineered to provide enough force to vibrate cleanroom clothing, shaking off particulates without causing discomfort to the operator.
2. Dual-Stage HEPA Filtration
Pre-Filters (G4 Grade): These capture 90% of large particles (10 microns and above), protecting the primary filter and extending its lifespan.
HEPA Filters (H14 Grade): Our primary filters offer 99.997% efficiency at 0.3 microns, ensuring the air used for scrubbing is ultra-clean.
3. Sophisticated PLC Control System
Every Rayshen Air Shower features an integrated Programmable Logic Controller (PLC). This allows facility managers to:
Adjust shower duration (standard 10–45 seconds).
Control lighting and fan delays.
Monitor filter pressure drops via Magnehelic gauges.
4. Electromagnetic Interlocking Doors
To prevent the "bypass" of air, our systems utilize a fail-safe interlocking mechanism. When the entry door is open, the exit door remains locked, ensuring the cleanroom is never directly exposed to the external environment.

Why Your Facility Needs an Industrial Air Shower
1. Pharmaceutical & Biotech Compliance
In the Pharmaceutical industry, contamination can lead to millions in losses. Rayshen Air Showers ensure compliance with EU GMP and FDA regulations by providing a validated method for personnel decontamination.
2. Yield Improvement in Electronics
For semiconductor and microelectronics manufacturing, even a single speck of dust can destroy a circuit. Our air showers significantly reduce the "Particle Per Minute" (PPM) count in entry zones, leading to higher production yields.
3. Healthcare and Isolation Wards
Hospitals use our air showers at the entry of Bone Marrow Transplant (BMT) units and isolation wards to protect immunocompromised patients from external pathogens.
Different Types of Air Showers We Manufacture
Personnel Air Showers
Our most popular model, designed for 1 to 2 people per cycle. Compact and efficient, these are perfect for research labs and small-scale production units.
Tunnel Air Showers
For high-traffic industrial plants, we manufacture Air Shower Tunnels. These allow multiple personnel to walk through in a continuous line during shift changes, preventing bottlenecks at the cleanroom entrance.
Cargo and Material Air Showers
These are larger units designed for trolleys, pallets, and heavy equipment. They often feature automatic sliding doors or high-speed roll-up doors to facilitate easy movement of goods.
Installation and Maintenance Guide
Site Requirements
Level Flooring: The unit must be placed on a perfectly level surface to ensure the magnetic locks align correctly.
Power Access: 3-phase power is required for industrial-grade blowers.
Clearance: Ensure at least 500mm of clearance at the top for motor maintenance.
Routine Maintenance Schedule
To keep your Rayshen Air Shower running at peak efficiency:
Monthly: Wash or vacuum the pre-filters.
Quarterly: Check air velocity at the nozzle tips using an anemometer.
Annually: Perform a PAO (Polyalphaolefin) test to ensure HEPA filter integrity. Replace HEPA filters every 2–3 years depending on usage.
Why Choose Rayshen? (The B2B Advantage)
