In this article, we'll detail the similarities, differences, and applications for a broad spectrum of Terra pass-through systems. Perhaps you need a simple and economical option for general tasks in labs, healthcare, or pharmacy environments. Meanwhile, Terra's cleanroom and specialty pass-throughs are designed and customizable for virtually any pharmaceutical, semiconductor, medical device, surgical, or ICU environment. Below, we'll identify several models that cater to general and technical users, including economical ValuLine models, BioSafe
In accordance with the ISO 14644 standards, ISO Class 7 cleanrooms represent a highly controlled environment that is engineered to maintain specific cleanliness values. The enclosed system encompasses ceiling-mounted fan filter units (FFUs) that generate a continuous supply of HEPA or ULPA-filtered air. In this article, we'll cover top-level considerations and standards for ISO 7 cleanroom design and construction. Additionally, we'll explore general principles for ISO 7 standards including particulate levels, ACH requirements, and equipment-based considerations among several unique applications.
Under ISO 14644-1, an ISO 6 cleanroom is a controlled environment that must maintain specific levels of air quality. Adherence to these limits is typically assessed using multi-channel particle counters, which measure the number of particles in the air at many different sampling points across the cleanroom.
The first consideration for ISO 5 cleanroom design is determining whether your application requires a positive or negative pressure design. The choice between positive and negative pressure cleanrooms is dictated by the broader goals of contamination prevention or containment. Each configuration serves distinct operational objectives.
ISO 5 rated cleanroom air is widely adopted as a minimum requirement for air quality when processing, packaging, or manufacturing products that are sensitive to microbes and ultra-fine particulates. In ISO 5 environments, airborne particulates are closely measured and monitored to ensure appropriate cleanliness for ISO 5 certification under ISO-14644-1.
Particulate and contamination arise from many different hosts including operators, clothing, processes, equipment, cleaning procedures, raw materials, and the introduction of outside air.
Subpar air quality detrimentally influences throughput, reproducibility, and shelf life across a multitude of life science applications, encompassing but not limited to in vitro fertilization, cell culturing, genomics, and proteomics.
Softwall cleanroom systems are an economical solution for controlling airborne particulates in addition to fume and aerosol management, ESD static control, or explosion-proof compliance. Designed with structural integrity in mind, Terra's frames accommodate multiple fan filter units without structural compromise. When integrated with mobile casters, these systems maximize versatility by permitting easy relocation.
Terra's prefabricated softwall cleanrooms are common for ISO 8 / ISO 7 cleanroom applications that moderate particulate control. Terra softwall rooms are rated for air quality classifications as low as ISO 6, however, efficiency trade-offs arise due to air leakage beneath the curtains. The trade off being, that any increase air leakage must be counteracted with additional make up air, which incurs additional operating costs to maintain positive pressure.
Terra provides five unique cleanroom construction solutions including pre-fabricated, stick-built, hybrid, modular, and custom-built. Each system has inherent benefits and advantages depending on the size, complexity, and cleanliness requirements of the build. Terra specialists will work with you to determine which system meets your needs for your specific budget, floor plan, cleanliness, or room-to-room requirements.
ISO 8 cleanroom design requires the understanding of several methodologies and procedures that evaluate airborne contamination levels including ISO 14644-1 to ISO 14644-8, ISO 14698-1, and ISO 14698-2.
