Different Types of Air Showers by the Top HVAC Companies in India

In the manufacturing plants of the pharmaceutical, semiconductor, medical device or biotech sectors, air contamination might be the reasons which can affect the efficiency and final product quality in the facility. HVAC companies in India create air showers for the cleanroom as the first defense system by terminating air particulates on the materials and people working before they step into the space. In this guide, we will discuss the air shower functionality, GMP standards, cost, and specifications by the renowned air shower manufacturers.

Definition of an air shower by the top HVAC companies in India

An air shower unit is a portable machine that is present at the entry point of any cleanroom. High-velocity air comes out of the unit with the help of nozzles, including a HEPA filter. This machine cleans the dust, air particulates, and lint contamination from the machines, raw materials and personnel before entering the cleanroom. In other words, air showers act like a barrier for the contaminants before anyone enters the cleanroom from the outside.

Working principle of air showers

The working mechanism of air showers by the top air shower manufacturers is simple. When personnel enter the booth of an air shower, the machine will automatically close the doors. Air comes out from the high-velocity nozzles in all directions. The unit also cleans all the dust and particles from the skin and other surfaces. The air shower will then circulate the clean and filtered air particles inside the room. The exit door to the entrance of the cleanroom will finally open. It takes nearly 15 to 30 seconds. Air showers by HVAC companies in India consist of the following components.

• Airflow design

The air flows out of an air shower with the help of HEPA and pre-filters through high-velocity nozzles. The airflow decontaminates the equipment surfaces and people before entering the cleanroom.

• Pressure-differentiating control

Air showers also help to maintain the pressure differentials between uncontrolled and controlled zones.

• Nozzle Designs

Most air showers made by the top HVAC companies in India contain 16 to 32 nozzles. These nozzles are composed of stainless steel and are present on the ceiling and side wall panels. Correct setup of the nozzles assists in complete contaminated particles from all sides.

Different types of Air showers by the HVAC companies in India

Depending on the intended use and applications, there are various types of air showers, as below, for the cleanrooms. If you use properly installed air showers, it will help in improved reduction in contamination and better compliance.

• Personnel

This type of air shower helps in cleaning personnel before they enter the controlled segment. It eliminates contaminants such as lint and dust present on the clothes in biotech, healthcare, pharmaceutical, and electronic cleanrooms. It is the most commonly used air shower in cleanrooms.

• Tunnel

This air shower is useful where a massive number of personnel entry and exits out of the cleanrooms or from a controlled environment. It allows numerous personnel to go through without compromising the contamination prevention procedure. Tunnel air showers are common in large-scale pharmaceutical niches.

• Stainless steel

Stainless steel grades SS316 and SS304 are used in this type of air shower because of their excellent corrosion resistance properties. Pharmaceutical sectors, biotech companies, hospitals and food processing industries primarily use stainless steel air showers.

• Cargo

It is mainly used for decontaminating pallets, product containers, equipment and materials entering the controlled environment.

FAQ

What is the importance of air showers in cleanroom designs?

Installation of air showers in the cleanroom design is not compulsory, but most HVAC companies in India highly recommend it, particularly for the pharmaceutical sector where there is a high chance of contamination. It can affect the final product. Thus, it is feasible to install the best air showers made by the top air shower manufacturers to prevent contamination.

Summing it up

Always select the best HVAC companies in India to install the air showers in the cleanrooms. They should specialize in air shower manufacturing to make sure about the cleanliness optimum level in any environment. Air shower eliminates the air particulates and dust contamination from equipment and personnel before they enter a cleanroom. Most of the air shower systems usually take 15 to 30 seconds for each cleaning cycle to complete. Many leading air shower manufacturers even offer personalization options in airflow, controls and dimensions to their customers.
