Do you know precision filter or security filter?

Precision filter is also called security filter, the cylinder shell is generally made of stainless steel, and the internal PP meltblown, wire burnt, folded, titanium filter element, activated carbon filter element and other tubular filter elements are used as filter elements, and different filter elements are selected according to different filtration mediums and design processes in order to meet the requirements of the effluent water quality. Used for solid-liquid separation of various suspensions, higher environmental requirements, filtration precision is relatively high filtration of pharmaceutical solutions, a wide range of applications, applicable to medicine, food, chemical industry, environmental protection, water treatment and other industrial fields.

Performance
(1) High filtration precision, uniform pore size of filter element;
(2) Small filtration resistance, large flux, strong dirt-trapping capacity, and long service life;
(3) High cleanliness of the filter element material, no pollution to the filter medium;
(4) Resistant to acid, alkali and other chemical solvents;
(5) High strength, high temperature resistance, the cartridge is not easy to deform;
(6) low price, low operating costs, easy to clean, replaceable filter element

Basic parameters
1. Filtration capacity T/H: 0.05-20
2. Filter using pressure mpa: 0.1-0.6
3. Filter specification pistil number: 1, 3, 5, 7, 9, 11, 13, 15,
4. Filter using temperature ° C: 5-55
Characteristics and applications of various filter cartridges Polytetrafluoroethylene membrane (PTFE) cartridges, polycondensation membrane (HE) cartridges, polypropylene membrane (PP) cartridges, acetate membrane (CN-CA) cartridges, filtration accuracy from 0.1-60um, the length of 10; 20; 30 and 40 inches (i.e., 250; 500; 750; 1,000mm) four kinds, the above The above cartridges are available in lengths of 10, 20, 30 and 40 inches (i.e. 250, 500, 750 and 1000mm), with a pressure resistance of 0.42mpa and can be backwashed. There are two types of interface: insertion type (222, 226) and flat spout type.
Characteristics
1. High performance removal of water, oil mist, solid particles, 100% removal of 0.01μm and above particles, oil mist concentration control at 0.01ppm/wt;
2. Reasonable structure, small volume, light weight;
3. With protective cover plastic shell and aluminum alloy shell can be selected;
4. Three-stage segmented purification treatment, long service life.
Maintenance
1. The core component of the security filter is the filtering cartridge, and the cartridge belongs to the easily damaged parts and needs special protection.
2, the security filter works for a long time, will intercept a certain amount of impurities, this will be when the work rate decreases, so it should be cleaned frequently, and at the same time, the filter element should be cleaned.
3, in the cleaning process, special attention should be paid to the cleaning of the filter element, do not deform or damage, otherwise it will lead to a reduction in filtration precision and fail to meet the production requirements.
4、If the filter element is found to be deformed or damaged, it must be replaced immediately.
5, some precision filter element, can not be repeatedly used many times, such as bag filter element, polypropylene filter element and so on.
