Product Description
Air shower is ideal supporting equipment for biological clean rooms and clean workshops. They are widely used for blowing off humans’ and their belongings’ surface dusts in micro-electronics, hospitals, pharmaceuticals, biochemical, food safety, fine chemical engineering, fine mechanics, productive facilities and scientific and research institutes, such as aviation and aerospace. Meanwhile, air showers also work as an air brake to prevent unpurified air from entering clean space. In one word, it is an effective equipment for cleansing humans and anti-air pollution in clean space.
Air shower is a necessary passage for person entering clean room in order to minimized the amount of particulate contaminant, achieve workplace strict clean purification standards. Personnel move through the air shower while particulate contaminants are blew off by the clean high speed air. So the dust cannot be brought into clean area.
Features:
- Photoelectric sensor, automatic blowing.
- Designed with circulation wind to measure the cleanliness of shower area under non-shower status.
- Double doors with electric interlock.
- LED display with adjustable blowing time (0-998).
- HEPA Filter, Class 100 cleanness.
The Personnel Air Shower from Getrus are fully self-contained units, designed to provide complete decontamination solutions for various clean room applications. They are ideally installed at the entrance of a clean room or controlled environment chamber to minimize the entry of dust and particulate matters inside the clean room via the clothes and skin surfaces of the personnel. Our Clean Room Air Shower feature programmable operating modes for flexible application and microprocessor based controller for precise supervision of the operating parameters. They use highly efficient pre-filters and HEPA filters for maintaining highly sterile working environments and an integrated fan/blower assembly to provide high velocity air streams for maximum scrubbing action against dust and particulate matters adherent on the exposed skin, clothes and material surfaces.
How an Air Shower Works
An air shower removes surface particulates through a timed, sensor-controlled air-blowing cycle. The process happens in four steps:
- Entry and interlock activation — The person or object enters through the entry door. A photoelectric sensor detects entry and activates the electric door interlock, locking both doors so the entry and cleanroom-side doors are never open at the same time.
- High-velocity air blowing — Multiple nozzles direct HEPA-filtered air at high velocity onto the person or object. The airflow creates a scrubbing effect on clothing and surfaces, dislodging dust and particulates.
- Recirculation and filtration — Air drawn back into the unit passes through pre-filters and HEPA filters again, so contaminated air is continuously cleaned rather than released into the cleanroom.
- Cycle completion and exit — Once the programmed blow time (adjustable from 0–998 seconds on the LED display) elapses, the interlock releases and the exit door unlocks.
This cycle is what allows an air shower to function as an “air brake” — a transition zone that keeps unfiltered air and loose particulates from following personnel into the clean space.

Standards & Compliance
Cleanroom air showers are generally expected to align with:
- ISO 14644-1 — classification of air cleanliness by particle concentration, the basis for “Class 100 / ISO Class 5” style ratings.
- ISO 14644-3 — test methods used to validate cleanroom and air shower performance.
- GMP (Good Manufacturing Practice) guidelines — relevant for pharmaceutical and biotech facilities.
- CE marking — relevant for electrical safety compliance where applicable.
Getrus should confirm and list which of these certifications apply to its specific air shower models, and link this section to the site’s existing Certifications page.
Safety Features
- Electric door interlock prevents both doors from opening at the same time, maintaining the pressure barrier between clean and unclean zones.
- Emergency stop (EMO) — an accessible emergency-off control that immediately ends the cycle and releases all interlocks if needed.
- Photoelectric entry sensors reduce the need for manual controls and ensure the cycle only runs when someone is present.
- Fail-safe unlocking — interlocks release automatically on power loss, so no one is ever trapped inside the chamber.
Installation & Maintenance
Installation: Air showers are typically supplied as factory-assembled or knock-down units for easy on-site installation, and are positioned at the transition point between a general area and the cleanroom, with electrical connection to the facility’s power supply and control panel.
Maintenance:
- Pre-filters should be inspected and cleaned periodically to protect the HEPA filter and maintain airflow efficiency.
- HEPA filters should be replaced based on manufacturer recommendations or when performance indicators show reduced filtration.
- Door interlocks, sensors, and the blower motor should be checked periodically as part of routine servicing.
Why Choose Getrus International
Getrus International manufactures cleanroom equipment — including air showers, pass boxes, laminar air flow units, and biosafety cabinets — from its manufacturing unit in Bahadurgarh, Haryana, with a corporate office in Mundka, New Delhi. Our air showers are built for pharmaceutical, electronics, healthcare, and research cleanroom applications, using HEPA filtration, microprocessor-based controls, and electric door interlocks to meet contamination-control requirements.
Frequently Asked Questions(FAQs)
Q1: What is an air shower used for?
An air shower is an enclosed chamber installed at a cleanroom entrance that uses HEPA-filtered, high-velocity air jets to remove dust and particulate contamination from personnel and equipment before they enter a controlled environment. It acts as a decontamination airlock between a general area and a cleanroom.
Q2: How does an air shower work?
When someone enters, a photoelectric sensor triggers the electric door interlock, locking both doors. High-velocity nozzles then blow HEPA-filtered air over the person for a set cycle time, dislodging particles from clothing and skin. The used air is filtered and recirculated, and the exit door unlocks once the cycle ends.
Q3: How long does an air shower cycle take?
Cycle time is typically adjustable, often in the range of 15–30 seconds, though controllers may allow programming anywhere from 0 to 998 seconds depending on the cleanroom’s required decontamination level.
Q4: What is the difference between a single-person and multi-person air shower?
A single-person air shower processes one individual per cycle and suits low-traffic cleanrooms. A multi-person or tunnel air shower accommodates several people at once, reducing wait times during shift changes in high-traffic facilities.
Q5: What standards do air showers comply with?
Air showers are generally designed around ISO 14644-1 (air cleanliness classification) and ISO 14644-3 (test methods), and pharmaceutical applications often require GMP compliance alongside relevant electrical safety certifications such as CE.
Q6: What is the difference between an air shower and laminar air flow (LAF)?
An air shower is an entry decontamination chamber for people, used briefly at the cleanroom threshold. A laminar air flow unit maintains a continuous, unidirectional stream of filtered air over a work surface, used throughout an active work session for sterile processing.
Final Thoughts
Contamination control isn’t a one-time checkbox — it’s a daily discipline, and the Air Shower Manufacturer is often the first line of defense in that discipline. Every person and object that passes through your cleanroom entry carries a contamination risk that no amount of downstream filtration can fully undo once particulates make it inside. A well-specified Air Shower Manufacturer, matched to your cleanroom’s classification, traffic volume, and industry requirements, closes that gap before it becomes a problem.
At Getrus International, we build air showers the same way we build the rest of our cleanroom equipment range — around your facility’s actual operating conditions, not a one-size-fits-all template. Whether you’re setting up a new pharmaceutical cleanroom, upgrading an electronics manufacturing line, or bringing an existing facility into compliance, our team can help you work out the right configuration, materials, and control features for your space.
