The full steel ventilation cabinet is a commonly used local exhaust equipment in laboratories. The following provides a detailed introduction from aspects such as material, structure, function, application scenarios, and purchasing considerations.：
Material and Craftsmanship: Double Protection of Corrosion Resistance and Durability
The cabinet of the full-steel ventilation cabinet is made of high-quality cold-rolled steel plate (typically 1.0-1.2mm thick), which is treated with acid washing and phosphatization before being coated with epoxy resin powder to form a dense protective layer. This process endows it with the following characteristics:
- Corrosion resistanceResistant to acids and alkalis (pH 1-14), and organic solvents (such as ethanol), suitable for the discharge of volatile reagents in chemical experiments.
- Flame resistanceSteel melting point exceeds 1500°C, withstands high-temperature environments, reduces fire risk.
- DurableCapacity exceeds 250 kg/m², capable of accommodating centrifuges, ultra-low temperature freezers, and other heavy equipment.
Some high-end models come with an integrated nano-silver ion antibacterial coating to inhibit bacterial growth, meeting the requirements of biological safety laboratories.
Section II: Structural Design: The Fusion of Modularity and Functionality
The full steel ventilation cabinet features an upper and lower split structure. The standard width ranges from 1000 to 2000mm, depth is 800mm, height is 2350mm, and the countertop height is from 800 to 900mm (suited for adult operation). Its core components include:
- Shelf-ready items：
- Adjustable Sliding DoorEquipped with a 5mm explosion-proof glass window, supports vertical sliding. During operation, lower the glass door as much as possible to minimize gas leakage.
- Flow guide plateSteel materials, with angular design to guide airflow evenly out, preventing recirculation inside the cabinet.
- Circuit ControlTouch switches, power outlets (IP65 protection rating), local exhaust systems with adjustable airspeed (usually 0.3-0.5 m/s).
- Lower cabinet section：
- Lab Bench TopOptional in stainless steel, epoxy resin, or ceramic, resistant to corrosion and high temperatures, easy to clean.
- Storage SpaceDrawer slides feature a three-section silent design, supporting a load of ≥50kg; cabinets are pre-equipped with gas interfaces (such as nitrogen, argon) and hot and cold water connections.
