Kỹ Thuật
A weighing booth (also known as a dispensing booth or sampling booth) is a specialized cleanroom enclosure designed to protect operators, products, and the surrounding environment during the weighing and handling of raw materials. Commonly used in pharmaceutical, food, cosmetic, and chemical industries, the booth ensures ISO-class air cleanliness by using HEPA filtration and vertical laminar airflow, helping to minimize cross-contamination and airborne dust.
The weighing booth works on the principle of vertical laminar airflow combined with negative pressure containment. Ambient air is drawn in through a G4 pre-filter and an F8 bag filter, then passes through a high-efficiency HEPA H14 filter (99.999% @ ≥0.3µm). Clean air is blown vertically downward over the work area at a velocity of 0.45 m/s (±20%), creating a localized clean zone.
About 90% of the air is recirculated, and 10% is exhausted to maintain negative pressure, preventing airborne particles from escaping into the external environment. This ensures both product protection and operator safety, complying with GMP standards.
Durable Frame: Made from stainless steel (SUS304) or powder-coated steel, ensuring longevity and easy cleaning.
Flexible Wall Options: Choose between PVC strip curtains, open-type, or powder-coated steel panels.
Door Options: Transparent PVC curtain or automatic high-speed roll-up door.
Return Air Filtration: Dual-stage system with G4 pre-filter and F8 bag filter (EN779 standard).
Supply Air Filtration: Equipped with HEPA H14 filter (EN1822), removing 99.999% of 0.3µm particles.
Adjustable Fan System: High-pressure blower fan with speed control for consistent airflow.
Downflow Air Velocity: Maintains clean airflow at 0.45 m/s (±20%), measured 15–30cm below the HEPA filter.
LED Lighting: Integrated LED lights for clear visibility and energy efficiency.
UV Sterilization: Built-in UV light for surface disinfection, controlled by remote.
Smart Control Panel: User-friendly interface to monitor airflow, lights, UV, and filter status.
Differential Pressure Gauge: Range 0–500 Pa to track filter performance and pressure balance.
PAO Test Port: Built-in PAO (DOP) port for HEPA filter integrity testing.
Power Outlet: Cleanroom-grade socket for weighing scales and other equipment.
