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 Process: Double Protection of Corrosion Resistance and Durability
The cabinet of the full steel ventilation cabinet is made of high-quality cold-rolled steel plates (typically 1.0-1.2mm thick), which are treated with acid pickling and phosphatization before being coated with epoxy resin powder to form a dense protective layer. This process endows it with the following characteristics:
- Corrosion resistanceCorrosion-resistant (pH 1-14), resistant to organic solvents (such as ethanol), suitable for the discharge of volatile reagents in chemical experiments.
- Flame retardancySteel melting point exceeds 1500°C, capable of withstanding high-temperature environments, reducing fire risk.
- DurableCapacity exceeds 250kg/m², suitable for heavy equipment such as centrifuges and ultra-low temperature freezers.
Some high-end models are equipped with an integrated nano-silver ion antibacterial coating, inhibiting bacterial growth and meeting the requirements of biosafety laboratories.
Section 2: Structural Design – The Fusion of Modularization and Functionality
The all-steel ventilation cabinet features a split-body structure with a standard width of 1000-2000mm, depth of 800mm, height of 2350mm, and countertop height of 800-900mm (suitable for adult operation). Its core components include:
- Shelf-ready items：
- Adjustable Sliding DoorEquipped with a 5mm explosion-proof glass window, supports up and down sliding. Lower the glass door as much as possible during operation to minimize gas leakage.
- Flow Control PlateSteel materials, designed with angles to evenly guide airflow out, preventing air swirl inside the cabinet.
- Electrical ControlTouch switches, power outlets (IP65 protection rating), local exhaust system with adjustable air speed (usually 0.3-0.5 m/s).
- Below Counter Section：
- Laboratory BenchtopOptional in stainless steel, epoxy resin, or ceramic materials; corrosion and heat resistant, easy to clean.
- Storage SpaceDrawer slides feature three-section silent design, bearing capacity ≥ 50kg; cabinet is pre-equipped with gas interfaces (such as nitrogen, argon) and hot and cold water interfaces.
