Domestic brand filter elements are all substitutes for the original brand filter elements produced by our company, and their filter materials are products of HV company imported from Germany with the registered trademark of “ Jiajie ” Cards
Other brands involved in the company have no brand significance, but are only used as a reference for product model and customer selection
Imported filter elements and filters are imported with original packaging and have anti-counterfeiting marks
Our company has been OEM various styles of compressed air precision filter elements for major domestic enterprises for a long time
Welcome to inquire!
I   Product introduction
Medical vacuum system is widely used in medical and surgical operations to provide timely and reliable attraction power
In the environment, the increasingly sensitive to pollution and the protection against infection make filtration the core of these systems

  Vacuum system filtration has been widely used
No inlet filtration will damage the vacuum pump and destroy the vacuum degree,   Cause pollution and equipment stop working
The pollutants in the inlet pipeline include particles, dust, water vapor and other gases
Outlet emissions will also include particles, oil and harmful gases
Professional inlet and exhaust filters can effectively deal with these pollutants
Professional sterilization and filtration are dangerous for a large number of bacteria in the pipeline and outlet of any vacuum system
In order to protect the health of patients, medical staff, other service personnel and people, it has been proposed to install and maintain bacterial filters before
Failure to install or maintain a sterilizing filter in front of the vacuum pump will not only damage the vacuum pump, but also make the vacuum pump a source of bacterial pollution
The proper temperature and humidity of the vacuum pump is the growth of bacteria, which will cause risks to the vacuum pump itself from a technical point of view, leading to the replacement of the vacuum pump

  Performance of vacuum sterilization filter
According to bs3928:1969 test method, when the filtration efficiency exceeds 99
995% and the vacuum degree is 630mbar, the differential pressure loss does not exceed 30mbar
  There are instructions for filter replacement and treatment
  As2896 medical gas system describes the inlet filter as follows: the medical inlet filter should be a bacterial filter, with appropriate size so that the pressure difference does not exceed 3
5kpa, and the filter element should be iso8573
1  0
01μ M

  Regulations on sterilization filter in technical specification for medical gas engineering:

2-mu; m
The filtration efficiency is 99
995%
Maintain the sterilizing filter and replace the filter element to prevent the system flow from being affected by excessive differential pressure

  The negative pressure sterilizing filter is mainly a large-area sterilizing filter element, with a quick installation structure, and the filtering accuracy is 0
22-mu; 0
01μ， The bacteria and various bacteriophages can be removed by 99
995% by using 121 ⌀ net steam for periodic sterilization
It is a link in the medical center suction system industry, and the sterilization filter is the choice of negative pressure air sterilization
The sterilizing filter is made of 304 or 316L stainless steel shell, which is polished with mirror to ensure that there is no dead corner of parasitic bacteria
The filter element of the sterilization filter adopts the steam sterilized PTFE folding filter element
The filter element has the characteristics of high pressure resistance, high temperature, hydrophobicity and high density

II   Installation and configuration
1 during installation, connect the pipes according to the air inlet and outlet labels on the filter
Otherwise, reverse installation of the inlet and outlet will affect the filtering effect
In order to facilitate use, replacement and maintenance, the filter should be installed according to the pipeline shown in the figure below
