When we talk about Safety – especially about machine safety devices or PPE – the term ergonomics often comes up. We use it to describe the features an object must have in order to adapt to the human body and to the way people actually use it. And when, unfortunately, a workplace accident occurs despite […]
For years we have been hearing about air quality, what we breathe, PM10, and so on. All of this, although critically important, tends not to shock us very much anymore. Let us put these general considerations aside and go back to the painting department, specifically to the area around the spray booth. Here, air monitoring […]
In recent years, the need to improve living standards and the quality and comfort of buildings has grown significantly, together with the need to limit heat losses as much as possible and therefore reduce energy consumption. As a result, both in new buildings and in the renovation of existing ones, we are seeing an increasing […]
In industrial ventilation and air handling systems, cleaning and maintaining filters is essential to ensure the energy efficiency of the system. A clean filter provides low pressure drop, stable airflow, and reduced electrical consumption, helping to keep the system consistently efficient and reliable. Why a clogged filter consumes more During operation, dust particles accumulate in […]
With the term Indoor Air Quality (IAQ – Indoor Air Quality) we refer to the quality of the air inside and around buildings, especially in relation to the health and comfort of occupants. In Italy, the Ministry for the Environment defines indoor pollution as “the presence, in the air of confined environments, of chemical, physical […]
A double-flow Heat Recovery Unit (HRU) is equipped with two main filter sections: Supply filter, which treats outdoor air before it is introduced into the indoor environment. Exhaust filter, which filters stale indoor air before it leaves the building, preventing coarse dust from depositing on the heat exchanger. Recommended filtration classes Exhaust filter: Class G4 […]
Replacing the filters of a controlled mechanical ventilation (HRU) system is a simple operation, but it requires some preliminary steps: identifying the filter section and the direction of the airflow. In a classic double-flow HRU, the filter sections are generally two: one for supply and one for exhaust. In some models, return filters and grille […]
Airflow visualization in clean environments is a practice prescribed by ISO 14644-3 among the control methods for cleanrooms. Methods for airflow visualization ISO 14644 provides that, to visualise airflow, several methods can be used, leading to both qualitative and quantitative assessments. Among the methods described are: tracer threads made of wool or similar, suitably positioned […]
Below are some freely adapted excerpts from ACR, The NADCA Standard (National Air Duct Cleaners Association) for the assessment, cleaning and restoration of HVAC systems (heating, ventilation and air conditioning). The latest edition of the standard can be accessed at the following web address: http://acrstandard.nadca.com/ This standard should be regarded as a technical reference and […]
Nitrile, latex and vinyl are the three most common materials used to manufacture disposable gloves. Latex gloves Latex gloves, made of natural rubber, are produced from the milky fluid tapped from the bark of the rubber tree (Hevea brasiliensis), a plant native to the Amazon that is now extensively cultivated in Malaysia, Indonesia, India, Vietnam […]
