Product Introduction

As a hospital-grade negative pressure machine, it is used to create negative pressure in a negative pressure isolation room to prevent contaminants, bacteria, and viruses inside from leaking outside by maintaining the pressure lower than the exterior.

Key Features

• Negative Pressure Machine for Isolation Rooms

  • This product is a negative pressure machine for isolation rooms, which has passed the leakage test by the Korea Filter Testing Institute.
  • It's a stand-type negative pressure machine suitable for hospital rooms, occupying less space and allowing air volume adjustment according to the room size.
  • Designed without gaps in the filter assembly area to prevent external contamination, it also features a lock to prevent unauthorized handling of contaminated filters.
  • It uses a low-noise blower, resulting in relatively low noise and power consumption.

  

• Two-Stage Filter Structure

  • The two-stage filter structure increases particulate removal efficiency and extends the filter's life.
  • The filter is designed to be filtered in the order of ① pre-filter ② HEPA filter to maximize performance.

  

• Stage 1: Pre-Filter

  • A pre-filter is installed to extend the life of the high-performance filter mounted downstream.
  • The pre-filter made of polyester material removes larger particles as the first stage of filtration.

  

• Stage 2: HEPA Filter

  • The HEPA filter ultimately removes the fine particles that pass through the first stage filter.
  • HEPA (High Efficiency Particulate Air) filters, developed for removing harmful microorganisms and radioactive substances, can remove more than 99.97% of particles when passing 0.3µm particles once.
  • The filter performance test has been completed by the Korea Filter Testing Institute.

  

• German-made Analog Differential Pressure Gauge

  • An analog differential pressure gauge from AFRISO, a globally recognized measurement device manufacturer from Germany, is installed for less frequent malfunctions and precise measurements.
  • The differential pressure gauge indicates when the filter is clogged, signaling when a replacement is necessary.

  

• Digital Manometer

  • A manometer is installed to display the pressure difference between the interior and exterior, allowing for the verification of negative pressure formation numerically.

  

Options (Optional)

• Flexible Conduit for Wires

  • Wires are covered with flexible conduits to prevent fire caused by insulation damage.

  

Precautions

• • This equipment is not suitable for uses other than negative pressure isolation rooms.
