Looking for a trusted air shower manufacturer in India? Cronax builds HEPA-filtered, GMP-compliant air showers for pharmaceutical, biotech, electronics & hospital cleanrooms.
Before a single person steps into your cleanroom, they carry millions of invisible threats — skin cells, lint, dust particles, and microorganisms that cling to clothing and equipment. No gowning protocol, no matter how rigorous, eliminates all of them.
That is exactly what an air shower does.
Cronax Industries, India's No.1 air shower manufacturer, builds high-performance air shower systems that decontaminate personnel and materials at the point of entry — before contamination reaches your controlled environment.
What Is an Air Shower?
An air shower is a sealed, self-contained decontamination chamber installed at the entry point of a cleanroom or controlled environment. When a person or object enters the chamber, high-velocity jets of HEPA-filtered air blast from multiple angles — physically dislodging and removing dust, particles, lint, and other contaminants from clothing and surfaces before they enter the cleanroom.
Think of it as a powerful, precision-controlled air bath that your team walks through every time they enter a critical area.
The chamber uses interlocked doors — the entry door must fully close before the exit door opens. This prevents unfiltered external air from bypassing the decontamination cycle and entering the cleanroom directly.
How Does a Cronax Air Shower Work — Step by Step
Step 1 — Entry and Sealing
Personnel or equipment enters through the first door, which automatically closes and seals the chamber. Both doors stay locked during the decontamination cycle.
Step 2 — Cycle Activation
The air shower activates automatically or manually. A programmable timer controls the cycle duration — typically between 15 and 45 seconds, depending on the application and contamination level.
Step 3 — HEPA Filtration
The blower system draws ambient air through HEPA or ULPA filters, which capture 99.97% to 99.9995% of particles as small as 0.3 microns — removing virtually all airborne contaminants before recirculating the air through the nozzles.
Step 4 — High-Velocity Air Jets
Strategically positioned nozzles deliver filtered air at velocities of 20 to 30 metres per second. This turbulent airflow creates a powerful scrubbing effect that physically strips loose particles from garments, gloves, and equipment surfaces.
Step 5 — Exhaust and Recirculation
Dislodged particles travel toward exhaust vents and wall plenums through a closed-loop return system. The contaminated air gets filtered again before recirculation — maintaining a clean environment inside the chamber throughout the cycle.
Step 6 — Exit to Cleanroom
Once the cycle completes, the exit door unlocks automatically. Personnel step directly into the cleanroom — decontaminated, compliant, and ready to work.
6 Reasons Your Cleanroom Facility Needs a Cronax Air Shower
1. Humans Are the Biggest Source of Contamination
Every person entering your cleanroom sheds thousands of particles per minute. Standard gowning reduces this — but it does not eliminate it. An air shower removes the residual contamination that gowning alone cannot address, making it the essential final step before cleanroom entry.
2. Regulatory Compliance Is Non-Negotiable
In 2026, regulatory bodies, including the CDSCO, USFDA, EU GMP, and WHO, have moved beyond suggesting contamination control equipment to mandating specific contamination control outcomes. Pharmaceutical, biotech, and medical device facilities that operate without air showers face serious compliance risk during audits and inspections.
3. One Contaminated Batch Costs More Than the Air Shower Itself
A single rejected pharmaceutical batch can be worth anywhere from ₹50 lakhs to ₹5 crores. The raw material waste, laboratory investigation costs, operational downtime, and regulatory penalties that follow a contamination event far exceed the cost of a properly installed air shower. Cronax air showers pay for themselves by preventing even one contamination incident.
4. HEPA Filtration Delivers ISO-Class Air Quality Inside the Chamber
Cronax air showers use H13 and H14 grade HEPA filters that capture 99.97% to 99.995% of particles down to 0.3 microns. This means the air blasting your team during decontamination is cleaner than the cleanroom itself — ensuring no secondary contamination occurs during the shower cycle.
5. Interlocked Doors Prevent Pressure Cascade Failures
The magnetic interlock system on Cronax air showers ensures that both doors never open simultaneously. This prevents unfiltered corridor air from bypassing the shower and entering the cleanroom — a critical safety feature for Grade A, B, and ISO Class 5 environments.
6. Automated Operation Eliminates Human Error
Cronax air showers operate with fully automated cycles, programmable timers, sensor-based activation, and digital control panels. Personnel cannot skip or shorten the decontamination cycle — ensuring every entry meets the same contamination control standard, every time.
Cronax Air Shower Product Range
Cronax manufactures a comprehensive range of air shower configurations to suit facilities of every size, layout, and classification requirement:
Single-Person Air Shower
Designed for individual entry, the single-person air shower is the most widely used configuration. It suits small to medium facilities with moderate cleanroom traffic. Compact, efficient, and fully automated.
Double-Person Air Shower
Accommodates two people simultaneously, improving throughput in busy facilities where multiple personnel enter the cleanroom at the same time. Reduces queue time without compromising decontamination effectiveness.
Air Shower Tunnel
Built for high-traffic facilities where large numbers of personnel move in and out of cleanrooms continuously. Air shower tunnels accommodate five or more people per cycle and are available in standard widths of 48 and 60 inches, with custom lengths up to 30 feet.
Goods and Material Air Shower
Designed for decontaminating equipment, carts, components, and materials — not just personnel. Wider dimensions and conveyor-compatible configurations allow materials to pass through the decontamination cycle before entering the cleanroom.
L-Shaped and Custom Configuration Air Showers
For facilities with space constraints or non-standard floor plans, Cronax manufactures L-shaped, one-way entry, two-way entry, and fully custom air shower configurations. Our engineering team designs each unit to integrate seamlessly with your existing cleanroom architecture.
Stainless Steel Air Showers
Built from 304-grade stainless steel for pharmaceutical, food-grade, and high-hygiene environments. Stainless steel construction resists corrosion, supports chemical cleaning, and meets GMP material requirements.

The Right Time to Install an Air Shower Is Before Contamination Costs You
Facilities that install Cronax air showers before an incident do not just avoid regulatory penalties and batch rejections — they build a culture of contamination control that protects product integrity, workforce safety, and brand reputation for the long term.
If your cleanroom is operating without a properly specified air shower, you are managing contamination risk reactively — and in regulated industries, reactive is expensive.
