A Hardwall cleanroom is an enclosed zone where airborne particulates and pollutants are maintained at specific levels. The cleanroom is used to filter polluted air as per the requirements of certain industries such as pharmaceuticals, E-liquids, healthcare facilities, as well as science and technology.
There are many types of contaminants that can harm the processes of research and production. Some of these include fibrous materials, aerosol particles, microorganisms, and chemical vapours among many others. We build Hardwall Modular Cleanrooms that are compliant to the international organisation for standardisation (ISO) 14644-1: 2015.
The ISO 14644-1:2015 standard of Hardwall Modular Cleanrooms are classified into different categories, from class 1 to 9. The classification of each Cleanroom changes dependent on size and prevalence of the air particulates in the cleanroom. Cleanrooms that fall in Class 1 (which is the greatest in the classification) are tested for the smallest air pollutant size and lowest frequency while Class 9 cleanrooms are tested for a larger air particulate size range and higher frequency.
Particle counters are employed as the test method for classifying Hardwall Modular Cleanrooms. This method measures the size and quantity of particles using the Particles Per Cubic Metre (PPCMM) unit. The Particles Per Cubic Metre of an (ISO) 14644-1: 2015 Class 9 Modular Cleanroom corresponds to normal atmospheric air with contaminants >5 microns not allowed into the environment.
With Class 1 Cleanrooms, the removal of much smaller air contaminants of sizes >0.1 and >0.2 microns are accounted for, which makes the enclosed air space cleaner than other classes. The following is an example of this standard of testing.
Class 7 Hardwall Modular Cleanrooms go through valuations that check for an air particulate size of >0.5 microns and a particulate count that shouldn’t exceed 352,000. The Hardwall Cleanroom will have to be modified and re-evaluated if it goes over the required particle count and size to qualify for the classification.
Production in a contamination-free environment
The use of HEPA/ULPA filtering technology is employed to achieve the level of clean air quality in Hardwall Modular Cleanrooms. The use of these filters have passed scientific evaluation and are proven to keep out certain amounts and sizes of air particulates from a cleanroom. Non-filtered air passes through Filter Fan Units (FFUs) creating a positive pressure area inside the cleanroom. This positive pressure helps maintain the controlled level of clean air by preventing contaminated air from entering back into the cleanroom through perforated openings.
The type of Hardwall Cleanroom aforementioned assures that only air that has passed through the filtration unit enters the internal area allowing for contamination-free production.
Modular Cleanroom Benefits
- Modular Construction
- Quick Assembly Time
- Airflow Control
- Inexpensive Modifications
With a Hardwall Cleanroom solution, there’s a low likelihood of product contamination and this is the first stage of securing a pollution-free production area. Putting clean air policies in place that will ensure particulates are not brought in by personnel working in the cleanroom is the next step in developing a clean production environment. One way to achieve this involves utilizing Cleanroom PPE such as overshoes, hair nets and gowning. Thus decreasing the number of potential contaminants that would otherwise infiltrate the Hardwall Cleanroom and disrupt production. Hardwall Cleanroom operators must undergo training in the reduction of contamination to prevent the introduction of microbial/foreign materials in to the production area.

You can be assured and have peace of mind in our solutions as you’ll receive a five-year warranty.
The use of a Cleanroom is crucial for any industry that requires their processes to have a reduced particulate occurrence to avoid the microbial spoiling and/or contamination of goods.
The need for a controlled air space makes the Cleanroom all the more essential as it mitigates the reduction of particulates through air filtration. Cleanrooms are used in industries such as food production, research, medical devices, electronics, production, Science and Technology, semiconductors and more.
At TCA, we are here to make sure you invest in the most suitable design for your application purposes. We can provide guidance concerning ideal Hardwall Cleanroom standards for you if you’re unsure about anything.
We only provide Hardwall Modular Cleanrooms that meet the ISO 14644-1: 2015 standard. These Cleanrooms range between ISO 1 and 9 classifications. Cleanrooms are put into different class according to the number and size of contaminants in the clean air area. To be categorised in the greatest classification (ISO 1), a Cleanroom will be tested for the smallest air pollutant size while Class 9 cleanrooms are tested for larger air particulate sizes and higher quantities.
The Cleanroom validation test method in which these Cleanrooms are classified is by use of particle counters, measuring the Particles Per Cubic Metre (PPCM). The use of particle counters accounts for the number and size of air particulates. ISO 1 rated cleanrooms are evaluated for the extraction of small air particulates >0.1 microns and >0.2 microns whereas an ISO 9 cleanroom, which has a similar PPCM to suburban air, will be tested for the removal of larger air contaminants >5 microns.

Containment solutions are important in situations where dangerous air particulates that emanate from the production process need to be prevented from contaminating the outside air. Hardwall Modular Cleanrooms can be made to keep production safe by introducing contamination-free air into the work space and contain hazardous materials that come about during production through the use of ULPA, HEPA, or Carbon filters. With our help at TCA, you can have containment solutions installed in your modular cleanroom that will see to the prevention of hazardous substances entering the outside air, keeping you out of the crosshairs of regulators.
Each containment solution we provide is unique as not two hazardous materials are the same and vary on quantities dependent on the use. This implies that every customer may require a different containment solution for their needs. We’ll cooperate with you to figure out the right containment plan for you.
Airflow and Filtration
Our Cleanrooms are designed to be compliant to the specified ISO 14644-1:2015 grading. With this in mind, we take into consideration the level of air filtration required and the end function of the cleanroom. The level of air filtration required is determined by the air changes per hour (ACH), this determines how many Filter Fan Units are to be used in the cleanroom. What we also determine by the strategic positioning of the FFUs and exhausts is the flow of air around the cleanroom. This can mean the difference between a uni-directional (laminar flow) and a non-unidirectional (turbulent flow) airflow around a cleanroom, potentially leading to a contaminated product. With this in mind, we can greatly increase the number of ACH and control the air flow within the cleanroom.
Filtration of air is controlled by our ultra-quiet, high-efficiency filtration modules. These filtration modules automatically compensate for a build-up of dust and other materials that occur over time within a HEPA/ULPA filter increasing the fan speed to reach the set flow rate. This increases the life of the filter, reducing cost overtime for the end user.
