Labeta negative pressure balance cover
The LABETA_SKF negative pressure balance cover is a precision airflow device that relies on negative pressure airflow to carry pollutants away and cap
Product details
  Negative pressure balance coverIt is a commonly used equipment in industries such as chemical, pharmaceutical, and food for weighing particulate matter such as dust. Its working principle is to use negative pressure to isolate the weighing area from the outside world and maintain a negative pressure state, thereby avoiding the leakage of dust and other particles. When performing weighing operations, the staff first opens the upper cover, pours the material into the upper cover, and then closes the upper cover. Through negative pressure, the direction of air flow inside the hood is from the outside to the inside, collecting dust and other particles into the lower hood and connecting them to the dust collector through an air duct for processing. After weighing, the staff can open the upper cover and take out the material. It has the advantages of high accuracy, easy operation, and environmental protection, and is therefore widely used in the weighing process of dust particles in industries such as chemical, pharmaceutical, and food.
  La BetaNegative pressure weighing hoodLABETA_AKFIt is a precision airflow device that relies on negative pressure airflow to remove and capture pollutants to the filter. Therefore, "guide wings" and "guide plates" are important means to control airflow, reduce turbulence, and prevent leakage. The airflow entering the hood is sorted by the "vertical guide plate" and can be "caught" and enter the cavity behind it. It is precisely because of the four "guiding wings" at the entrance that small interfering airflows can smoothly enter the negative pressure hood without escaping.
The LABETA_SKF negative pressure weighing hood has passed the OEB-5 test with excellent data and can be used for weighing operations with an OEL target of<1ug/m ³.
