The CM Ductless Filtered Storage Cabinet from Kenton Apparatus Co., Ltd. is different from traditional externally exhausted chemical storage cabinets. It is equipped with a built-in negative pressure control system, ensuring that the air pressure inside the cabinet remains lower than the surrounding environment. This helps effectively lock volatile TVOC and other chemical gases inside the cabinet.
After passing through the multi-layer filtration and purification system, the purified air is safely returned to the indoor environment. No external ductwork or structural modification to the existing laboratory is required, allowing the cabinet to be used immediately after power connection. This makes it especially suitable for renovated laboratories or spaces with limited installation conditions.
Core Technology: Negative Pressure Control + Multi-Layer Filtration to Prevent Gas Leakage
The negative pressure control technology continuously maintains a negative pressure environment inside the cabinet, preventing chemical gases from escaping at the source and helping protect laboratory personnel.
The multi-layer filtration system can be configured with high-efficiency activated carbon or specialised chemical filter media according to the characteristics of the stored chemicals. It provides targeted purification for organic solvents, acidic gases, alkaline gases, and other hazardous substances.
The internal circulation design also reduces the additional load on laboratory air-conditioning and ventilation systems. Compared with traditional external exhaust systems, it offers more stable operation and significantly lower energy consumption.
Intelligent Management and Flexible Classification
The CM Ductless Filtered Storage Cabinet supports classified storage of different chemicals. Users can freely divide storage areas for acids, alkalis, organic solvents, and other categories.
The system can automatically adjust the filtration air speed according to real-time TVOC and hazardous gas concentration levels. It can also be equipped with intelligent management functions, such as card access control, storage and retrieval records, and filter saturation alarms, helping laboratories achieve safer, smarter, and more compliant chemical management.
Two Key Highlights for Strict Laboratory Requirements
Highlight 1: Optional U.S. Purafil High-Efficiency Filter
For special or high-concentration volatile chemicals, users can choose to equip the cabinet with U.S. Purafil filters, a globally recognised brand in the field of gas-phase filtration. Purafil filter media offers high adsorption capacity and broad-spectrum removal performance. It is especially effective for difficult-to-adsorb pollutants such as formaldehyde, hydrogen sulfide, and organic acids, helping raise the cabinet’s protection level to a higher industry standard.
Highlight 2: Customisation for Special Customer Requirements with Third-Party Test Reports
Kenton Apparatus Co., Ltd. can customise the filter media formula and cabinet structure according to the actual types and concentrations of chemicals stored by the customer, as well as the required cabinet size.
Third-party authoritative test reports can also be provided, offering reliable supporting evidence for laboratories preparing for safety inspections, compliance reviews, and internal management audits.
