Filter of negative pressure suction system
【1】 Introduction of negative pressure suction system
1. Medical suction system generally includes vacuum pump, vacuum tank, check valve and other components
(1) the medical suction system shall be equipped with a standby vacuum pump. When a single vacuum pump with large flow fails, the rest of the vacuum pumps shall still meet the design flow;
(2) the vacuum unit shall be equipped with anti backflow device;
2. Design considerations of negative pressure suction system
(1) the suction machine room should be close to the user's center; the suction machine room should be set separately from the air compressor room, and there must be a physical partition
(2) the medical attraction system of the independent infectious disease department medical building should be set up independently; for example, the independent infection building should be set up separately. In the small infection outpatient area, due to the small flow of the system, whether to set up an independent system in the actual project will be determined after technical and economic comparison.
(3) the exhaust port of the suction system shall be located outdoors, not at the same height as the medical air inlet, and the distance from the doors, windows and other openings of the building shall not be less than 3m. The medical suction system shall be equipped with bacterial filter or other sterilization and disinfection measures. This is the standard requirement of medical gas and the provision of article 8.2.9 of green hospital building evaluation standard (GB / t51153-2015), which accounts for more than 5% of the score items of indoor environmental control of green hospital building. Therefore, the technical measures for bacterial filtration and discharge outlet setting shall be specified in the future design to avoid losing points due to missing items.
(4) due to the specification: the drainage of liquid ring vacuum pump shall be discharged after the sewage treatment is qualified, and it shall comply with the current national standard gb18466-2005 discharge standard of water pollutants for medical institutions. Therefore, in principle, other forms should be given priority in design.
(5) select a complete set of vacuum suction unit with automatic control, which not only improves the reliability of the system, but also saves the space of the machine room, and is the main trend of future configuration

Filter shell is specially designed for the sterilization filter element of Dominic hand, and has Zui high standard of biosafety.
Features of high flow filter:
Specially designed for air filtration, low pressure drop; internal sanitary polishing, external mirror, sand blasting and other treatment;
The ball gate filter cartridge is designed to prevent jumping off and reduce the high heat conduction of steam fire bacteria;
Electric heating jacket can be added below zva-01a; steam jacket can be added above zva-011.
The unique heat-resistant polypropylene outer sheath and 316L stainless steel central column are not only resistant to 142 ℃ steam sterilization, but also have a porosity of 300% of the competitors. The structure is solid, and the air flow resistance is reduced to Zui low.
Special sizes are available in our company. The domestic brand filter elements of our company are all self-made alternative filter elements. The filter materials are imported from HV company of Germany, with the registered trademark of "Jiajie". Other brands involved in our company have no brand significance, but are only used as model reference and use reference.
