An open-front downflow booth that combines HEPA-filtered vertical air supply with low-level returns and slight negative pressure for cleaner powder weighing and dispensing.
- Vertical HEPA Downflow
- Low-Level Dust Capture
- Open-Front Access
- Monitored Negative Pressure
مقدمة المنتج
The negative pressure weighing booth forms a localized clean-air zone around balances, containers and manual dispensing work. Filtered air descends from the overhead diffuser and carries liberated particles toward low-level rear returns, while a controlled exhaust fraction keeps the booth below the surrounding room pressure. Stainless interior panels, flush lighting and accessible filter sections support cleaning and routine airflow verification.
الخصائص الرئيسية
Three low rear returns capture particles close to the work surface.
Partial exhaust establishes inward flow across the open booth face.
A flush control screen displays fan, pressure and filter-condition information.
مخاوف المنتج للعملاء
Manual weighing can release fine powder at the balance and container rim, creating operator exposure and cross-contamination risks.
Dust can rise into the operator breathing zone during pouring.Vertical filtered downflow sweeps particles toward returns below the working height.
An open work face can allow powder to escape into the cleanroom.A controlled exhaust fraction maintains inward air movement across the booth opening.
Obstructed returns create unstable airflow around equipment.Multiple low-level grilles spread capture across the rear wall and simplify placement planning.
Filter loading may go unnoticed between service intervals.Differential-pressure monitoring provides a visible indication of changing filter resistance.
