  • Negative Pressure Weighing Room


    The weighing booth consists of the working area , the return air box, fan cabinet, the air outlet box, and outer cabinet these several parts assembled. Control panel is located on the front of the inside working, micro touch-screen control panel with fan switches on/off, adjust the fan operating mode , adjust the workspace air velocity functions. Equipped with differential pressure gauge, test the resistance of the filter. Inside the air supply box designed with air exhausting regulation board that can adjust the air exhaust volume within a reasonable range.

    Working Principle:

    The weighing booth designed vertical one-way airflow form, return air must first filtered through the primary filter disposed the large dust particles of the airflows, and then through the medium filter for second times filtration to full protect usage of HEPA filters.

    Under pressure of centrifugal blower through the HEPA filter, so as to meet cleanliness requirements. Clean air is sent to the air supply box, 90% were through the air diffuser panels forming a current vertical air flow, 10% through the airflow volume adjust board exhausted out. All airflow have been processed through HEPA filter, so air supply and exhaust are not with the residual dust can avoid secondary pollution.

    Due to the formation of a stable unidirectional airflow in the work area, so emitted dust in this area will be under the influence of a one-way flow trapped by the primary and medium filters.

    Devices with 10% air exhaust, creating a negative pressure relative to the external environment, to ensure that the dust in this region will not spread to the outside, play a role in protecting the external environment.
