The comprehensive maintenance cycle of the aluminum frame combined filter is not a fixed value. It needs to be comprehensively judged based on the usage environment, filtration load and type of filter material. The following are specific reference standards:
I. Basic Comprehensive Maintenance Cycle (Regular Environment)
In environments with low dust concentrations such as ordinary office Spaces and commercial buildings, it is recommended to conduct a comprehensive maintenance every three months.
The contents include: inspection of the integrity of the aluminum frame structure (deformation, rust, sealing condition), assessment of the cleanliness of the filter material, comparative analysis of pressure difference data, and recheck of installation sealing performance, etc.
Ii. Periodic Adjustment under Special Circumstances
Highly polluted environment
For places with high dust/fiber concentrations such as industrial workshops, construction sites, and textile factories, it is recommended to shorten the comprehensive maintenance to once every 1-2 months.
The reason is that the filter material is prone to rapid clogging, and the aluminum frame may also wear out more rapidly due to the erosion of contaminants. More frequent inspections are needed to prevent filter failure.
Damp/corrosive environment
For instance, in food processing workshops, chemical workshops, etc., it is recommended to conduct a comprehensive maintenance every two months, with a focus on checking the rusting of aluminum frames and the moisture and mold problems of filter materials.
Clean environment
For instance, in general hospital wards and electronic dust-free workshops (low-level), the comprehensive maintenance can be appropriately extended to once every 4 to 6 months, but it should be flexibly adjusted in combination with the pressure difference monitoring data.
Iii. Key Reference Indicators (Prioritized over Fixed Periods)
When the following situations occur, comprehensive maintenance must be carried out immediately, regardless of whether a fixed cycle has been reached:
The pressure difference before and after the filter reaches more than twice the initial resistance (monitored by a differential pressure gauge);
It is visible to the naked eye that the surface of the filter material is severely dusty, discolored or damaged.
The aluminum frame has obvious deformation and the sealing rubber strip has fallen off, etc.
The air volume of the ventilation system has significantly decreased or the operating noise is abnormal.
Resumen
The core principle of the comprehensive maintenance cycle is that “the worse the environment, the shorter the cycle.” “Abnormal indicators. Immediate maintenance.” In actual operation, it is recommended to formulate a personalized maintenance plan by combining fixed cycles with real-time monitoring data (such as pressure difference and air volume) to balance filtration efficiency and usage cost.
