음압 무게 부스 (Negative - Pressure Weighing Booth)

A powder weighing enclosure operated below the surrounding room pressure so air moves inward through the access opening and airborne material stays within the controlled filtration path.

상품 소개

This booth adds a controlled negative-pressure relationship to the normal downflow weighing layout. Air enters through the open access face, joins the filtered vertical supply and returns through low-level extraction grilles. A monitored exhaust branch maintains the inward boundary while staged filters retain airborne powder. The booth pressure, airflow and building exhaust connection are selected for the material hazard and room arrangement rather than assigned one universal containment value.

주요 기능

A controlled exhaust branch keeps the booth below the adjacent room pressure.

Inward air at the access opening opposes powder migration into the corridor.

Low-level returns capture powder without directing a strong stream across the balance pan.

Differential-pressure monitoring distinguishes booth pressure from filter loading.

Contained filter-change options reduce contact with collected powder during maintenance.

고객 제품 관심사

Higher-risk powder weighing needs an inward containment boundary without making the balance unstable or exhausting uncontrolled dust downstream.

Powder can escape through the open booth face during container handling.Monitored inward face air carries released dust into the controlled return path.

Strong extraction creates unstable balance readings.A low-turbulence supply and remote low return grilles keep high velocity away from the pan.

Filter loading changes the room-to-booth pressure relationship.Separate pressure sensing tracks filter resistance and the containment boundary.

Maintenance opens contaminated filter compartments to the room.Bag-in/bag-out or other contained change arrangements isolate the loaded filters.
