Ceiling Type Recirculation HEPA Fan System

Resirkülasyonlu HEPA Fan Sistem

  • Hybrid airflow by unique HEPA Fan Filter units and sophis ated
    CFD modelling
  • Under-filter laminar airflow
  • Turbulent airflow in the rest of the room
  • Air sweep method in the entranceway with overflow air
  • Increased modularity with a decentralized air movement approach
  • Flexibility to control all interiors independently
  • Standart cihaz tasarımı, otomasyon kontrol ve alarm özellikleri ile güvenli operasyon
  • Improved adaptation without additional reconstructions as needs change
  • Variety of control and automation options that can be managed according to all building requirements
  • High-performance efficiency and besides ease maintenance and operation, recovery of investment in a short time by eliminating unnecessary operation and energy loss

  • ≥ACH 4
Airflow Type
  • Laminar
Air Mixing Factor M          (ASHRAE Standard)
  • 1:1
Air Cleaning Class         (FED209E / ISO Standards)
  • Class 100 / ISO5
Filters (EN1822)
  • Pre-filter-1 EU4
  • Main filter HEPA, H14 %99,995 0,3 µm
  • The system can be turned on and off by the On/Off Button, the air flow adjustment with the air speed adjustment potentiometer, the pressure switch on the HEPA fan and the filter control lamp are active when the filter is full and it warns the user visually to change the filter.
  • With the Wall-mounted temperature and humidity sensor, the temperature and humidity of the ambient air, the pressure of the ambient air with the pressure sensor that can measure between 0-25 Pa, the total air flow flowing over the HEPA Fan with the vane type air velocity sensor can be monitored instantly via the PLC with the touch screen. Energy saving is provided with stand-by mode. Low air flow, technical service maintenance and UV lamp replacement alarms warn the user audibly and visually when the number of changes in the relevant filter and the number of air changes in the environment are 5 or less as a result of the filters getting dirty.
  • If there is a pressurization unit in the system, if the ambient differential pressure is not at the desired value, the pressure alarm warns the user audibly and visually.
  • Quality management systems, CE, ISO14644 Cleanrooms and associated controlled environments, EN 61010 Safety requirements for electrical equipment for measurement, control and laboratory use, Accredited Testing Institution Validation Guarantee (If the installation is done by Metis Certified Technical Personnel)
Application Area
Neutropenic Patient Isolation RoomIn oncology and hematology services, these patients, whose White blood cell count has fallen below the protective level of the body as a side effect of cancer or chemotherapy, are also sensitive and vulnerable to microorganisms that cannot cause infection in normal people. In the case of hospital infection, poor prognosis and mortality rates, as well as increased length of hospital stay, are negatively affected by their psychological state and increasing cost processes. Therefore, it is very important to isolate neutropenic patients in the hospital environments. (2007 Guideline for Isolation Precautions: Preventing Transmission of Infectious Agents in Healthcare Settings)
Infectious Patient Isolation RoomThese rooms, also called quarantine rooms, require hepa filtration under negative air pressure and in a way that does not spread germs to the environment. In addition, when the infection of the hospitalized patient is detected, similar measures should be taken to prevent it from infecting the hospital staff and other patients.(Guidelines for Environmental Infection Control in Health-Care Facilities, CDC 2003)
