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 purity, such as cleanrooms, biological laboratories, and semiconductor laboratories.Here is a detailed introduction to the PP ventilation cabinets:

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% of 98% sulfuric acid and other highly corrosive media for extended periods.
2. Features：

• Corrosion resistanceThe key components such as the cabinet, operating surface, and adjustable doors are all made from high-quality pure PP board, with thickness ranging generally between 8-12mm, ensuring long-term stable operation.
• SealabilityPrecision-engineered sealing structure, paired with an efficient ventilation system, effectively prevents the leakage of harmful gases.
• Environmental Protection & Energy EfficiencyPP material is recyclable and operates with low energy consumption, meeting energy-saving and emission-reduction requirements.
• Lightweight and durableLightweight, rust and dust-resistant, easy to install and maintain.

II. Structural Design and Function

1. Structure：

• Adjustable GateManufactured with 4mm thick transparent acrylic glass or 5mm thick tempered glass, boasts excellent acid and alkali resistance. The frame is securely integrated with a thick porcelain white PP board C-channel, ensuring both safety and durability.
• Wind Speed ControlEquipped with fixed, variable, or adaptive airflow control systems, wind speed can be adjusted according to experimental requirements to ensure stable and even airflow.
• Lighting SystemUtilize LED daylight lamps or all-encompassing three-proof lighting fixtures to ensure ample illumination and the accuracy of experimental operations.
• Waste gas emissionsAir is drawn into the fume hood by 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 features multiple power outlets with splash-proof covers (such as AC220V/10A), convenient for the use of experimental equipment.
• Water Supply SystemSome fume hoods are available with an optional water supply system, including imported one-piece molded PP cup grooves and corrosion-resistant nozzles, to meet experimental water requirements.
• Control PanelEquipped with a liquid crystal display panel, it offers functions such as adjustable air volume, lighting control, and power management, with easy and efficient operation.
