Softwall Cleanroom: The Complete FAQs Guide

Cleanrooms can help you achieve a lot as a manufacturing company or a pharmaceutical company. That is why more industries are finding it necessary to own a cleanroom. Well, the softwall cleanroom makes things even better. How better, you ask? Keep reading this FAQs guide to learn more about such a type of cleanroom.

What is a Softwall Cleanroom?

Not all applications will require setting up a full-scale cleanroom with complete wall panels. There is another option, which is a softwall cleanroom. The softwall cleanroom is characterized by having curtains to replace the wall panels. These curtains will be cut a few inches before the floor to provide enough space to exhaust the air used in the cleanroom.

Besides having the curtains as the walls, they will also have solid aluminum frame structures to support the air handling system located at the top of the softwall cleanroom.

The best part is that the softwall cleanroom can be available in different classes, so talking to Zonsteel can help you understand which class would be ideal for your needs.

What is the Difference Between Softwall Cleanroom and Hardwall Cleanroom?

The major difference between these cleanroom types is how they are built.

A hardwall cleanroom will have a rigid wall structure mostly made of insulated sandwich panels. The enclosed space will have air vents for exhausting air, depending on how the air handling system will be set up. Such a cleanroom will also hold a higher pressure differential necessary for offering better cleanliness levels.

The hardwall cleanrooms are the most popular because of their functionality. They can also be adapted to different applications better than using softwall cleanrooms.

The softwall cleanroom, on the other hand, is a cleanroom with a simple aluminum or steel frame structure with curtains working as the walls of the cleanroom. The curtains are mostly made of flexible PVC material that provides good durability even if you have to use the cleanroom more often.

The curtains are cut a few inches before the floor to provide space for exhausting the air that might be in the softwall cleanroom.

A softwall cleanroom would have a lower positive pressure compared to the hardwall cleanroom. It is why you would get them mostly used for cleanrooms that need lower cleanliness ratings. This does not mean that you cannot get a softwall cleanroom with the highest cleanliness rating.

So, it is possible to see how it will be affordable than the other types of cleanrooms.

Ease of assembly

Even when other cleanrooms are claimed to be set up within a few days or weeks, the softwall cleanroom can be ready for use within hours. Most of the time, the frame is what will take time to setup. However, once they are set up, the addition of curtains and other equipment should be easy.

There is no doubt the frame is always the core of the softwall cleanroom. Zonsteel understands this, and that is why the frame is made of strong aluminum material. This type of material will not easily corrode even if it is exposed to the elements for long.

The other options for the frame include powder-coated steel columns and beams. Such materials are good for ensuring they can also handle the elements better while improving the durability of the softwall cleanroom.

The PVC material used to make the curtains will also last for longer. So, you are not likely to start replacing parts on your softwall cleanroom anytime soon.

Other than the usual cleaning, the other type of maintenance you might have to do is changing the fan filter unit filters and lights whenever they are damaged.

The HEPA lifespan, on average, is two to five years. It can be more depending on the environment. If there is too much dust in the area, the lifespan will be shorter. Also, the prefilter cleanliness needs to be monitored, and order replacements where necessary.
