High-Performance Ductless Fume Hoods for Safe and Efficient Laboratory Operations

Cruma’s ductless fume hoods provide cutting-edge filtration technology, ensuring a clean and safe work environment. These fume hoods are designed to eliminate contaminating gases, solid particles, and aerosols from laboratory air while being easy to install and energy-efficient. With Cruma’s patented filtration system, these hoods offer optimal air purification without requiring external ducts, making them a versatile and cost-effective solution for modern laboratories.

Key Benefits of Ductless Fume Hoods

  • Plug-and-Play Setup: These fume hoods are delivered ready for use. Simply unpack, install the filters, plug in, and start working – no complicated installation required.
  • Enhanced Safety for Users: The advanced filtration system captures toxic fumes and particulates, ensuring that hazardous materials remain inside the fume hood, keeping both the operator and the environment safe.
  • Energy Efficient Air Recirculation: The filtered air is recirculated back into the laboratory, reducing the need for additional heating or air conditioning. This results in significant energy savings and lower operating costs.
  • No External Ducting Required: Unlike traditional fume hoods, Cruma’s ductless fume hoods do not require external conduits to expel contaminated air, making them easy to install in buildings with multiple floors or limited ventilation.
  • Relocatable and Flexible: The mobile base with wheels allows for easy relocation within the lab, providing flexibility in placement without the need for permanent installations.

Advanced Features of Plug-and-Play Fume Hoods

  • Real-Time Monitoring with LCD Display: The large 127x34mm display provides critical information such as airspeed, filter status, expiration dates, and operational hours, ensuring optimal performance at all times.
  • Filter Saturation Test: Equipped with a filter saturation test, this ensures that the filters are functioning efficiently and alerts users when replacements are needed.
  • Comprehensive Alarms and Alerts: The system includes a range of alarms for open doors, expired filters, and airflow monitoring to ensure maximum safety.
  • Energy-Efficient LED Lighting: Powerful 900 lux LED lighting illuminates the workspace, making it easier to perform precision tasks.
  • Hot Wire Anemometer: Provides accurate airflow readings for improved safety monitoring.
  • Tempered Glass Worktop and Liquid Tray: The worktop is made of tempered safety glass, and the integrated liquid retention tray ensures that spills are contained for easy cleaning.
  • Ergonomic Design: With ergonomic openings and armrests, these fume hoods provide comfort for users during long work sessions.
