PP fume hoods are specialized ventilation equipment made of polypropylene (PP) for acid and alkali resistance, widely used in laboratory environments requiring high-intensity acid and alkali operations and high cleanliness, such as cleanrooms, biological laboratories, and semiconductor laboratories.Here is a detailed introduction to the PP Exhaust Fume Cupboard:

I. Core Material and Characteristics

1. MaterialManufactured from polypropylene (PP), a lightweight, corrosion-resistant thermoplastic resin with excellent resistance to most acids, bases, and organic solvents. For instance, it can withstand concentrations of ≤30% for extended periods.Hydrofluoric Acid98% Concentrated Sulfuric Acid, 40% SolutionSodium hydroxideExposure to highly corrosive media.
2. Features：

• Corrosion resistanceThe cabinet, operating surface, adjustable doors, and other critical components are all made from high-quality pure PP board, with thickness ranging typically between 8-12mm, ensuring long-term stable operation.
• SealabilityA precisely designed sealing structure, combined with an efficient ventilation system, effectively prevents the leakage of harmful gases.
• Eco-friendly and energy-savingPP material is recyclable and operates with low energy consumption, meeting energy-saving and emission-reduction requirements.
• Lightweight and durableLightweight, corrosion and dust-resistant, easy to install and maintain.

II. Structural Design and Function

1. Structure：

• Adjustable DoorManufactured with 4mm thick transparent acrylic glass or 5mm thick tempered glass, offering excellent acid and alkali resistance. The frame is securely combined with a thick porcelain white PP board C-channel, ensuring safety and durability.
• Wind Speed ControlEquipped with fixed, variable, or adaptive airflow control systems, capable of adjusting wind speed to meet experimental requirements, ensuring a stable and uniform airflow.
• Luminaire SystemUtilizing LED daylight lamps or all-weather three-proof lighting fixtures, ample illumination is provided to ensure the accuracy of experimental operations.
• Waste gas emissionsAir is drawn into the fume hood through internal fans, purified through pre-efficiency and high-efficiency filters (such as HEPA filters), and then exhausted outdoors to prevent harmful substances from escaping.

1. Features：

• Pre-outletEach fume hood typically comes equipped with multiple power outlets featuring splash-proof covers (e.g., AC220V/10A), facilitating the use of experimental equipment.
• Water Supply SystemPartial ventilation cabinets are available with an optional water supply system, including imported one-piece molded PP cup grooves, corrosion-resistant nozzles, etc., to meet experimental water requirements.
• Control PanelEquipped with a liquid crystal display panel, offering functions such as adjustable air volume, lighting control, and power management, with easy and efficient operation.
