The ultimate safeguard for extreme corrosive environments. The WINLAB Premium PP Fume Hood is engineered specifically for trace metal analysis, semiconductor cleanrooms, and rigorous chemical laboratories handling highly aggressive acids (such as Hydrofluoric acid, Aqua Regia, and concentrated Sulfuric acid). By eliminating vulnerable metal components, this 100% metal-free unit guarantees zero rust, zero cross-contamination, and a permanent lifespan under the harshest chemical vapor conditions.
Advanced Aerodynamic & Containment System
Seamless Engineering for Absolute Containment
Monolithic PP Shell: The entire main body and base cabinet are constructed from 8-12mm high-purity, porcelain white Polypropylene (PP) sheets.
Seamless Thermal Welding: Precision-welded into a single continuous piece using color-matched and homogenous PP electrodes. This zero-gap construction ensures toxic liquids and fumes can never penetrate or pool in crevices.
Spill-Proof Work Surface: Features a heavy-duty 12mm porcelain white PP worktop, engineered with edges thickened to 24mm to form a marine-edge containment lip, preventing highly corrosive spills from reaching the operator. (Optional upgrades: Epoxy Resin, Phenolic Resin, or Technical Ceramic).
Advanced Aerodynamic System
Optimized Airflow in a Corrosive Environment
Aerodynamic PP Airfoil: A streamlined lower curve allows inflow air to smoothly sweep the work surface. This minimizes turbulence, maximizes containment, and reduces exhaust energy consumption by 7-10%.
VAV-Compatible Bypass Slots: Features a compensating bypass airflow design. It maintains a stable and safe face velocity (0.3 ~ 0.8 m/s) to protect the operator, automatically adjusting volume as the sash is raised or lowered.
Removable PP Baffle System: A meticulously engineered three-stage baffle ensures no airflow blind angles. It effortlessly extracts toxic gases of varying specific gravities (from light volatile solvents to heavy acid fumes). Easily removable for deep chamber cleaning.
Corrosion-Proof Sash & Hardware Engineering
Where Competitors Rust, WINLAB Endures
100% Non-Metallic Hardware: Unlike standard hoods that use vulnerable steel hinges, WINLAB utilizes high-strength injection-molded PP hinges, PP handles, and PP structural fasteners to guarantee zero metal exposure to corrosive fumes.
Explosion-Proof Sash: 5mm tempered safety glass encased in a chemical-resistant PP or epoxy-coated frame, ensuring operator protection against chemical splashes and micro-explosions.
Frictionless Pulley & Belt System: Utilizes a heavy-duty PP+Fiber synchronous belt and PP pulleys. Designed by the weight-balance method, it delivers silent, smooth, and permanently rust-free sash movement.
Smart Controls & Integrated Utilities
Centralized Controller: An intuitive LCD digital touch panel positioned safely outside the fume zone. Controls power, exhaust fans, LED illumination (>300 LUX), and optional sterilization.
Isolated Electrical System: All electrical components (junction boxes, circuit boards, AC contactors, and splash-proof sockets) are fully sealed and isolated from the internal fume chamber to prevent acid-induced short circuits.
Sewerage System: Integrated high-density PP oval cup sink, crucially equipped with an anti-siphon bottle trap to block noxious sewer gases and highly corrosive waste backflow.
