Do You Need A Soundproof Cleanroom?

Do You Need A Soundproof Cleanroom?

A cleanroom can be designed to meet the needs of almost any application with any requirements, from controlling static and humidity to even controlling sound. You probably know whether your application requires control for things like humidity and static, but what about sound. Do you need a soundproof cleanroom? Here are some conditions where you might.

Loud Manufacturing Environments

If your facility is a manufacturing environment that requires protective hearing equipment like earplugs ear, soundproofing your cleanroom is a good idea, especially if hearing protection isn’t necessary for your cleanroom processes. Hearing protection might even hinder those processes, as foam from earplugs and earmuffs can hold and shed particles.

If your cleanroom contains the loud equipment and the rest of your processes outside the cleanroom don’t require hearing protection, it can be worthwhile to soundproof your cleanroom so that hearing protection is only required inside. This can greatly reduce hearing-related injuries to your personnel and reduce the cost of hearing protection for your company.

Loud Equipment Containment

If you have a piece of equipment or pieces of equipment that are particularly loud, rather than creating a soundproof cleanroom, a more efficient solution might be creating a soundproof containment room for that equipment. A modular soundproof room can be created around a loud piece of equipment. The benefit to this is reduced noise and need for ear protection in your facility. Additionally, modular containment rooms can be freestanding or can incorporate your existing structure, so no matter where a piece of equipment is housed, it can be soundproofed.

Sensitive Processes

If your cleanroom operation is a particularly sensitive process, a soundproof cleanroom may also be beneficial. Sound is vibration, and delicate operations may be affected by loud noises and strong vibrations, which a soundproof cleanroom can reduce.

Proprietary Information

If your cleanroom operations are top secret or deal with proprietary information which should not leave the walls of the cleanroom, a soundproof cleanroom can also prevent the unplanned and unwanted spread of information by containing sound within the cleanroom.

Cleanroom Terminology: Air Showers

Cleanroom Terminology: Air Showers

Early in the cleanroom design process, all of the cleanroom terminology and jargon can be confusing, especially when designing a controlled environment is a complex process with many factors to take into account. Here’s an explainer on one of those terms, air showers, that may help you determine whether your cleanroom requires an air shower.

What are air showers?

Air showers are enclosed spaces that use high-velocity air jets to remove contaminants from people and items entering the controlled environment. They are placed at all entrances to the cleanroom and are connected to a HEPA or ULPA filtration system. Air showers can be used to prevent contaminants from entering the cleanroom, but they can also be used to remove contaminants from people and objects exiting a quarantine or other controlled environment to prevent cross contamination.

Air showers are particularly useful for cleanrooms requiring a high level of control, such as ISO Classes 1-5. Industries that commonly use air showers include pharmaceuticals, biotech, hospitals, aerospace, and semiconductor manufacturing.

Air Shower Specifics

All air showers function in the same way—air blows onto the person or object in the air shower, blowing loose contaminants off before the person or object enters the cleanroom space. The differences are really in size, materials, and filtration system.

Size

The size of your air shower will depend on what needs to pass through it. If only people will be passing through your air shower, then you won’t need a large one (depending on the number of people). However, if carts with product need to enter your cleanroom, your air shower will need to accommodate the person pushing the cart as well as the cart.

Materials

Air showers are generally constructed from either steel, aluminum, stainless steel, or plastics. The material used may depend on your budget as well as the application and requirements of the air shower.

Filtration system

Air showers can use HEPA (high-efficiency particulate air) filters or ULPA (ultra-low particulate air) filters, depending on your needs. HEPA filters remove particles greater than or equal to 0.3 µm with 99.99 percent efficiency; ULPA filters remove particles greater than or equal to 0.12 µm with 99.9995 percent efficiency.
