The high temperature resistant and high efficiency filter uses a partition design, and the corrugated partition can accurately maintain the spacing of the pleats, and maximize the use of the filter material under the minimum resistance. The filter material has 180 pleated pleats on both sides. There are two indentations when bending, so that it is opened into a wedge-shaped box pleat at the rear end of the separator, and the wedge-shaped box pleat can prevent the filter material from being damaged. The core material of the high temperature resistant filter is glass fiber filter paper, the outer frame is stainless steel frame or aluminum frame, the sealant is high temperature resistant silica gel, and the sealing gasket is glass fiber (frsi) and silicone rubber (kseries). Efficiency: 99.95%@MPPS, 99.99%@0.3μm, 99.97%@0.3μm Efficiency class: H13 (EN1822), the highest temperature resistance for continuous operation: 250°C (frsi), 260 (kseries). When using a high-efficiency filter, pay attention to the following:
1. The filtration efficiency of high temperature and high efficiency filter
The 250℃-resistant red high-temperature silica gel and the 350-400℃-resistant black high-temperature inorganic glue used are affected by the physical properties of the glue (the fluidity is too poor), so the actual filtration efficiency of the 250℃ H13 high-temperature high-efficiency filter is between H12-H13; The actual filtration efficiency of 350-400℃ H13 high temperature high efficiency filter is between H11-H12.
2. Precautions before using high temperature and high efficiency filter
Because the organic silica gel and inorganic glue used in the high-temperature resistant high-efficiency filter are cured from the surface in the curing process, the thicker the glue injection, the more difficult it is to cure. Under normal circumstances, the glue curing time is 3-7 days. The cured high-temperature and high-efficiency filter is directly installed on the high-temperature equipment for normal use, which will inevitably cause the high-temperature glue to crack, expand and the glue to detach from the outer frame. In response to the above problems, the following two solutions are specially made:
1. The high temperature and high efficiency filter needs to be used normally after 7 days;
2. If the customer needs to install it immediately, it is recommended that the customer must operate the following methods before using our high temperature and high efficiency filter:
The high-efficiency filter with high temperature resistance to 250 °C is slowly heated to 100 °C in the high-temperature equipment, and then stopped for cooling after 2 hours of constant temperature;
Adjust the temperature to 150°C for 1 hour and then shut down for cooling
Adjust the temperature to 200°C for 1 hour and then shut down for cooling
Adjust the temperature to 250°C for 1 hour and then shut down for cooling
After the last slow cooling, it can be used normally.
350-400 ℃ high temperature resistant high-efficiency filter is slowly heated to 100 ℃ in the high temperature equipment, and then shut down for cooling after 2 hours of constant temperature;
Adjust the temperature to 150°C for 1 hour and then shut down for cooling
Adjust the temperature to 200°C for 1 hour and then shut down for cooling
Adjust the temperature to 250°C for 1 hour and then shut down for cooling
Adjust the temperature to 300°C for 1 hour and then shut down for cooling
Adjust the temperature to 350°C for 1 hour and then shut down for cooling
Adjust the temperature to 400°C for 1 hour and then shut down for cooling
After the last slow cooling, it can be used normally.
