Chongqing Green New Supply HEPA 99.99%

Description: outlet typically contain valves, housing and filter outlet is the uppermost layer of the diffusion plate, air and wind into the box through the diffuser plate, and then filtered through a filter of wind sent from the lowermost diffuser plate. Shell with high-quality cold-rolled steel production integration HEPA, the surface electrostatic spray, containing plenum, high efficiency filter, diffuser plate, the renovation and new clean room at all levels, it can be used as a terminal device in a clean and efficient filtration ceiling etc., with less investment, simple construction and so on. Chongqing Green New Purification Technology Co., Ltd. has a professional R & D and production team to ensure product quality and price concessions, welcome your patronage. HEPA structure and characteristics: 1, HEPA comprising: a housing, diffuser plate, high efficiency filter, manual control valve family of four. 2. Cabinet Material: paint or stainless steel cold-rolled steel; 3, diffuser plate: ensure airflow jet speed to prevent the generation of eddy currents; 4, air supply mode: points and the top side of the inlet into the wind, flanged There are square and round two structures; 5, cotton insulation available. HEPA Features: HEPA applies to all levels, a variety of non-roof structures are flow clean room (1000-30 ten thousand), designed using the latest technology in Japan, with the versatility, performance, reliability, low investment, construction the advantages of simple, compact, efficient and convenient filter replacement, easy maintenance features. Cleanroom terminal purification equipment the best choice. The wind side with the diffuser plate, both to ensure clean air jet velocity filtered, and can prevent the generation of eddy currents, non-current-ideal cleanroom [1] usually HEPA [1] before and after the pressure table or differential pressure sensor, then the coarse filter, when the pressure is greater than 250Pa, necessary to change; for in effect filter, when pressure is greater than 350Pa, necessary to change; on sub-efficient filter, when the pressure When the difference is greater than 400Pa, it is necessary to change, and the original filter no longer apply. [2] In order to give full play to the role of a filter, in the selection and application process, the filter face velocity, coarse, medium efficiency filters should not exceed 2.5m / s, sub-efficient filter and high efficiency filter should not exceed 1.5m / s. This is not only conducive to ensure efficiency of the filter can extend filter life and cost savings. [3] when the device is not to replace the filter operation in general; as a result of time to replace the filter and can not stop operation, only allows the replacement of crude at constant fan status, in effect filters; sub-high efficiency filter and high efficiency filter It is required only after replacing the suspended air. [4] Under normal operating conditions, the flat, foldable coarse or medium efficiency filters, common from January to February for once, after the media can change down soaked with water, rinse, then dry it and then put; common Up to rinse 1-2 times, new filters must be replaced to ensure the filtration efficiency. [5] between the filter and the adapter frame seals, must close, no leakage, in order to ensure the filtering effect. [6] For sub-efficient filter, under normal use conditions (even eight hours a day, continuous operation), ordinary use six months or so, it should be replaced. [7] on the need for high humidity, high temperature environment, high efficiency filter, it is necessary to select high temperature, high humidity filter paper and the separation plate, a housing material to meet the demand. [8] bag coarse or medium efficiency filters, under normal use conditions (even eight hours a day, continuous operation), the general use around 10 weeks which should change a new one. [9] biological clean room and pharmaceutical clean room, must choose the metal casing the air filter, and its appearance should not rust, does not allow the use of wood-framed panels of filters to prevent producing bacteria, the impact of qualified products. [10] For HEPA, when the inside of the high efficiency filter resistance value is greater than 450Pa; or when the outlet side air speed to a minimum, even if the change coarse, after the effect of the filter, the air flow velocity can not increase ; or when the high efficiency filter outer rendered irreparable leakage condition, shall be changed to a new high-efficiency filter; such as the absence of such conditions, the general situation can be based on the use of environmental conditions, 1--2-year change again.
