Frequently Asked Questions

Why do I need a cleanroom?
Many industries rely on cleanroom technology. Industries like electronic, high-tech, semiconductor, pharmaceutical, aerospace, and the medical industry, all require cleanrooms as a necessary part of the manufacturing process. As products such as cell phones and microchips get smaller, the chance for contamination during the manufacturing processes gets higher. For these types of companies, clean, safe, contaminant-free products are essential to manufacturing and distributing a profitable product.
Can I redesign my cleanroom when my needs change?
Yes. Every company’s needs change over time, and an Angstrom Technology cleanroom can change right along with them. All of our cleanrooms are modular, meaning they can be expanded or decreased in size, components can be added or removed, and any number of other changes can be made to your existing room.
What sort of company should design, install and equip my cleanroom?
With all the different requirements for cleanrooms, you need a company that can take care of those technical needs. Angstrom Technology is an expert in all aspects of cleanroom design, installation, renovation, and maintenance. We’re here to help you with anything you need for your cleanroom: before, during and after the installation. We even have all of the supplies you need to make your room operate efficiently after its installation.
Will I need an engineer or architect to design my room?
Nope. Not only are we cleanroom experts, we’re also engineers! Our cleanroom specialists are highly experienced in all facets of the cleanroom industry, including design. We can design the entire room for you, or work with your staff to create the perfect room for your needs. Our cleanrooms are pre-fabricated, completely customizable and designed exactly to your specs.
What kind of cleanroom do I need?
That depends on what you will use it for. With so many different options, we can design a cleanroom that fits your requirements now, and for years to come. Contact us today to discuss your options and find the perfect room for your project.
Can I use my existing building structure?
Yes. Our HardWall and RigidWall cleanrooms can be installed in a variety of environments using your existing building. Contact our cleanroom specialists and we’ll visit you on-site to discuss your framework and recommend a cleanroom that will work best within your existing structure. SoftWall cleanrooms are typically only designed as free-standing structures.
How is the quality of Ångstrom Technology’s cleanrooms?
Ångstrom Technology’s cleanrooms are prefabricated and thoroughly inspected before shipping. However, the completed cleanroom is only as good as the construction crew. If your crew installs the room, we’ll provide complete installation instructions. Or, have Angstrom Technology build your room; we guarantee the quality of our workmanship and products for one full year.
How much will my cleanroom cost?
Again, it depends on what you will use it for and what class of cleanroom you need. As your requirements get stricter, the cost usually gets higher. For instance, a Class 100 cleanroom will cost more than a Class 10,000 cleanroom. Costs associated with filtration, temperature, humidity control and other factors can increase or decrease the price. Because of the many variables, it is impossible to give an estimate for your project here on our website, but if you fill out the ‘Cleanroom Quote Questionnaire’ we’ll have a cost estimate for you as soon as possible.
How does the cost of a modular cleanroom compare with conventional construction?
When you compare features, installation, and maintenance of a modular cleanroom to conventional construction, the modular room will always cost less. It’s also worth mentioning that you can depreciate a modular room up to five times faster than a conventional room.
How is faster depreciation of a modular Cleanroom beneficial to my company?
With current tax laws, the bottom line is that the initial cost of a conventional construction would need to be over 30 percent less to match the tax advantages of a modular cleanroom.
Can my cleanroom be relocated and reused?
Yes. All Angstrom Technology cleanrooms are easily relocated, with components that knock down and reinstall quickly. Your cleanroom is a long-term investment that moves when you do.
Do you lease Cleanrooms?
Yes. Long and short term leases are available, as well as pre-owned equipment. Oftentimes, that’s just as cost effective as leasing.
How strong are the walls?
HardWall Cleanroom walls are made of fiberglass, aluminum, steel, plastic laminate, reinforced plastic or vinyl. SoftWall and RigidWall cleanroom walls are made of reinforced plastic, plastic laminate or vinyl. Each type of wall has its own benefits and we’ll be happy to help you decide which will work best for you. All walls are impact resistant for longevity, and will hold up to your working conditions for years.
Does a Cleanroom control sound?
Yes, it can. Depending on the type of room, and the type of walls, a cleanroom can control sound in even the loudest manufacturing conditions. If sound control is an issue to your company, let us know and we can design a room specifically for your needs.
How fast can I start using my Cleanroom?
The rooms are typically installed within 2-4 weeks. Smaller rooms may take less time, and large rooms may require a little more time. But with an industry standard of 4-8 weeks for delivery, you get exactly what you need in a shorter amount of time with Angstrom Technology.
Will the construction disrupt my facility?
Any type of construction will disrupt your facility to some degree, however the more quickly you can install the cleanroom, the less disruptive construction will be. Since Angstrom Technology installs and delivers quicker than others, you’ll have fewer disruptions.
Will there be any mess from the assembly of the Cleanroom?
Any type of cleanroom assembly will leave a mess, however Angstrom Technology’s cleanrooms are simple to install, and come with minimal packaging, so you have less to clean up. If you don’t have time to worry about any of the clean up, let us install the cleanroom for you. Our professional installation crew will take care of everything, right down to cleaning up every little piece of trash.
Are permits needed?
Small rooms within a plant or other existing building typically do not require a permit, but you should consult your local building codes department before you begin. Large rooms can require a permit in some cases. Angstrom Technology’s cleanroom experts can help you determine if a permit may be necessary, and help you work local building code authorities.
What are my options for air circulation?
There are many different options for airflow in your cleanroom. Some options require air plenums (empty space for air recirculation), and others use air from outside the room. One type is no better than another; your needs dictate which will work best. We’re happy to discuss your needs and recommend an air circulation system that will fit your project.
