## [Commissioning, Validation and Maintenance](/en-US/applications/cleanrooms-and-regulated-environments/commissioning-validation-and-maintenance) ![Commissioning, Validation and Maintenance](/sites/default/files/entityone_paragraphs/images/Commissioning%2C-Validation-and-Maintenance.png) HVAC engineers are involved at various stages in the life of a ventilation system – starting with the commissioning phase, when they check that all the system components are designed, installed, tested and used in a way that meets the operational specifications set by the project managers and the customer. These vital checks ensure that the ventilation system operates as efficiently as possible right from the outset. Validation is an important process for any cleanroom. It serves to ensure that the cleanroom is properly installed and designed for its intended ISO classification and that all of the components (facility, environment, equipment) meet regulatory requirements and other defined standards. Therefore, validation consist in “Establishing documented evidence that provides a high degree of assurance that a specific process will consistently produce a product meeting its predetermined specifications and quality attributes” (GMT Draft Annex 1). Our instruments are quick and easy to use while catering to every professional requirement. Aside from commissioning and validation, a building’s ventilation system will require routine preventive maintenance. Once again, this process involves measuring all relevant parameters in order to detect even the slightest problem or defect, with clogged filters being the most common issue. Each of these tasks can only be carried out using premium, portable, lab-calibrated measurement instruments. Our instruments are quick and easy to use while catering to every professional requirement, saving engineers and technicians precious time and allowing them to focus on their core areas of expertise. Multifunction ## Multifunction Commissioning and maintaining ventilation systems involves measuring a wide range of air parameters, from temperature, pressure, and air flow and velocity, to humidity, CO2 concentration and more. That’s why portable, multifunction instruments are the tool of choice for these tasks. These instruments are specially designed with measurement precision and resolution in mind, adhering to the extremely fine margins required by controlled-environment standards. Sauermann has extensive expertise in manufacturing premium measurement instruments that deliver the high degree of accuracy required in laboratories, clean rooms and other critical environments. These instruments are specially designed with measurement precision and resolution in mind, adhering to the extremely fine margins required by controlled-environment standards. Sauermann’s portable multifunction devices are some of the most advanced commissioning, testing, balancing and maintenance instruments on the market. And because they’re built for reliability, speed and user-friendliness, they help professionals work more efficiently. What’s more, their modular design and range of attachable probes lets engineers build a custom measurement solution – all calibrated in Sauermann’s in-house laboratories, which are accredited by COFRAC to ISO 17025:2017.

That’s why we designed the DBM 620 air flow meter specifically for this purpose: to easily calculate the ACR via the accompanying mobile app. Air flow readings play a key role in making granular adjustments to pressure cascades in controlled-atmosphere buildings. This process, known as balancing, maintains extremely precise differential pressures (marginal differences of less than 15 Pa) in order to prevent the spread of contaminants without generating turbulence. An air flow meter is the most versatile and effective handheld instrument for measuring vent air flow. Regularly replacing the air in a room – by bringing in a flow of fresh, filtered air from outside – is also the most effective way to reduce concentrations of chemical compounds, bacteria, viruses, aerosols and particles. Measuring the ACR is therefore equally important in ensuring that the air inside a confined space is clean and healthy. An air flow meter is the most versatile and effective portable instrument for measuring air flow. It is compatible with all types of air vent – incoming and outgoing – and far outperforms other solutions when it comes to measurement accuracy.
