Maintaining optimal performance and longevity of your baghouse system requires regular and thorough inspections.
Routine baghouse inspections are critical to ensure the system operates efficiently and complies with environmental regulations. Examinations help identify issues such as bag wear (sleeves or socks), seal leaks, and buildup of materials, which can lead to reduced efficiency and increased emissions if not addressed promptly.

Key Components
1. Visual Examination
Visual examinations are the first step in a comprehensive baghouse inspection. Inspect the exterior and interior for signs of wear, damage, or corrosion. Special attention should be given to baghouse inspection holes, which provide access points for more detailed internal examinations. When inspecting and checking, it is necessary to examine the housing and hoppers for leaks. Air infiltration above 15% reduces cleaning efficiency by 40%.
2. Bag Examination
Use a detailed baghouse inspection checklist to ensure all aspects are covered. Inspect the filters for tension, completeness, quality of attachment, absence of tears, holes, presence and tightness of spacer rings, and correct fabric selection. To check the bag tension, compress it by hand; the walls should converge towards the axis and then return to their original position when the hand is removed. There should be no sagging of the fabric.
3. Seals and Gaskets
Inspect all seals and gaskets for wear or damage. Properly functioning seals are essential to maintain the system's efficiency and prevent leaks.

4. Cleaning System
Check the cleaning system to ensure it is functioning correctly. Whether the system uses pulse jet, reverse air, or shaker cleaning, it should be operating effectively to clean the sleeves and maintain airflow. Inspect the cams, levers, bearing units, shafts, and pins of the shaking mechanisms. All moving surfaces should be lubricated. The surface temperature during filter operation should not exceed 140°F. Verify the frequency of the regeneration system, and the condition and operation of the solenoid valves. Inspect the condition of the heater and backflush fan.

Check the operation of the shaking mechanism and the mechanism for backflushing the sleeves with clean air:
- Ensure clear shaking periodicity: the number of cam mechanism strikes and the shaking period are determined specifically for each type of baghouse.
- Maintain sectional shaking and backflushing.
- Duration of impulses during pulse regeneration with compressed air (should be 0.1 – 0.2 s).
- Adhere to the design pressure for bag backflushing (specific to each type of equipment).
Pneumatic Cleaning System
5. System Parameters
- Exceeding the allowable temperature of the gases being cleaned for the specific type of fabric drastically reduces fabric life. At temperatures below the dew point, moisture condensation is possible, accompanied by the formation of deposits that cannot be removed or complete loss of fabric permeability ("clogging" of the sleeves).
- Increasing resistance indicates insufficient regeneration of the bags, whereas a decrease in resistance occurs due to their wear and tear.
- The flow rate and dust content of the gas for each brand and size of filter should be determined specifically. If the dust concentration exceeds 0.00125 lb/ft³ it is advisable to have a preliminary stage of coarse dust collection before the filters.
- Inspect the condition, completeness, and operation of measuring instruments and automation provided by the project.
- Verify the operation of the dust discharge device and the regularity of dust removal.
