Routine maintenance of clean, clean room and clean shop air filter maintenance is a big expense, but maintain the cleanliness of the air is necessary for the requirements of the production of environmental pollution, that high efficiency filter maintenance and efficient air traps were installed in the replacement of standard what is it? usually air filter, especially high efficiency air filter packaging, transportation, installation and use are in accordance with the standard requirements of the manufacturer of high efficiency filter in order to ensure high efficiency air filters the results. Various types of air filters in use for some time, because the filter media surface trapping all kinds of dust, so that the filtration efficiency of the air filter and air filter resistance decreased, affecting the central air conditioning unit or clean projects supporting the efficient delivery outlet air flow, cleanliness and efficiency in the use and need in a timely manner to replace the air filter, to ensure the cleanliness of the air requirements. 
 Various types of air filter, high efficiency air filter before installing, do not allow hand tearing or open bags or packaging film; air filter should be stored in strict accordance with the direction of the standard high efficiency filter on the box marked; in a high efficiency particulate air course of the removal of the filter, light, light, and avoid severe vibration and impact. 
 2 for the high efficiency filter, the installation direction must be correct: in vertical installation with combination filter of corrugated sheets, corrugated board must be perpendicular to the ground; filter in the connection between the vertical and the framework is strictly prohibited leakage, deformation, damage and leakage, such as plastic, the installation must ensure that the inner wall of clean, no dust, grease, rust and other debris. . 
 Three test methods: observation or a white silk cloth to wipe the check. 
 (4) high efficiency filter prior to installation, clean room full cleaning, wipe clean within the air-conditioning system if dust should be re-cleaning, wipe the reach cleaning requirements. Sandwich or ceiling to install a high efficiency filter layer or ceiling should be a comprehensive cleaning wipe. 
 (5) transport and storage of high efficiency filter should be set aside in accordance with the direction of the signs of plant. During transport, light light up, to prevent severe vibration and impact can not force the loading and unloading. 
 High efficiency filter before installation at the installation site unpack visual inspection, including: filter paper, sealants and frames for damage; side length, diagonal, and thickness dimensions to meet the requirements; framework with or without glitches and rust (metal frame); with or without certification, technical performance meets the design requirements. Qualified should be immediately installed in accordance with national standards "clean room construction and acceptance of" JGJ71 [90] provides methods to check. 
 Cleanliness level equal to and higher than 100 clean room, high efficiency filter, install the former should be "clean room construction and acceptance of" the [JGJ71-90] provisions leak, and to meet the requirements. 
 Installation of high efficiency filters, the arrow on the frame and the air flow direction consistent; vertical installation, the filter paper crease direction should be perpendicular to the ground. 
 Installation of coarse flat or folded filter should be made of galvanized mesh in the back of the wind direction. Installation of bag filters, you should make the bag length direction perpendicular to the ground, do not make the bag parallel to the direction to be installed on the ground; 
 10 under normal conditions of use, flat folding coarse or medium efficiency filters, generally from January to March to replace time requirements of the lax area can be soaked in water filter replacement down with detergent, Rinse and then dry it and then replaced; usually wash 1-2 times, you must replace the new filter to ensure that the filtration efficiency. 
 11 for the bag of coarse or medium filter, under normal conditions of use (an average of eight hours a day, continuous operation), generally used for 7-9 weeks should be replaced with new. 
 12 sub-efficient filter, under normal conditions of use (an average of eight hours a day, continuous operation), the general use of 5 - 6 months, should also be replaced. 
 13 for the above filter, the filter before and after the differential pressure gauge or differential pressure sensor, coarse filter, when the differential pressure value is greater than 250Pa, must be replaced; in effect filter, the pressure difference greater than 330Pa, it must be replaced; sub-efficient filter, when the differential pressure value is greater than 400Pa, and must be replaced, and the original filter is not re-use; 
 14 for the high efficiency filter when the filter resistance value is greater than 450Pa; or when the flow velocity of the wind surface to a minimum, even if the replacement of the coarse, medium filter, air velocity still can not increase; or when high efficiency filter surface leakage can not be patched, shall be replacement of the high efficiency filter; the absence of such conditions, generally based on the use of environmental conditions, 1-2-year replacement. 
 15 in order to give full play to the role of the filter, the process of selection and use of the filter face velocity, coarse, medium efficiency filters should not be greater than 2.5m / s, sub-high efficiency filter and high efficiency filter should not be 1.5m / s, so that not only help ensure the efficiency of the filter, but also extend filter life and cost savings. 
 16 in equipment operation, generally do not change the filter; as a result of filter replacement period can not stop replacement, only allows non-stop fan replacement crude, medium efficiency filters; sub-efficient filter and high efficiency filter must stop the air supply before replacement. 
 17 seal between the filter and connected to the frame pads, must be tight, no leakage, to ensure that the filtering effect. 
 18 needed for the high efficiency filter in the high humidity, high temperature environment, you must select the high-temperature, high humidity resistance of the filter paper and dividers, box material, in order to meet production requirements. 
 19 bio-clean rooms and pharmaceutical clean room must be selected filter of the metal frame, body, and its surface should be easy to rust, does not allow the use of wooden frame board filter to prevent the resulting bacteria, affecting the qualified products 
 The company aims: 
 Purification equipment of the Company's production of all free one year warranty, which provides long-term technical support. 
 2, the Pearl River Delta, free delivery, installation. 
 3, fault accepted: 48 hours to reach outside the province, within 24 hours to reach.
