The cleaning cycle of the automatic double-opening air shower should be classified based on the type of components, the dust concentration in the usage environment, and the operating frequency of the equipment. The core cleaning/maintenance cycle is as follows:
1. Internal cleaning (wall panels, floor, nozzles
Basic cycle: Clean after daily use (wipe with a lint-free cloth to remove surface dust and debris);
Enhanced cleaning: Deep wiping every week (targeting dead corners such as nozzle gaps and grooves of door body sealing strips);
Special scenarios: If it is applied in industries with a large amount of dust (such as building materials, metal processing) or used more than 10 times a day, it should be changed to cleaning per shift (once in the morning and once in the evening).
2. Pre-filter (Primary filter)
Cleaning cycle: Once a week (blow with compressed air or rinse with clean water, dry and reinstall);
Replacement threshold: When the number of water washes reaches 3 times or the pressure difference is ≥200Pa, replace directly (no further cleaning is required).
Special scenarios: In high-dust environments, reduce the purging to once every three days. Replace in a timely manner when the pressure difference rises rapidly.
3. High-efficiency filter
Cleaning instructions: The high-efficiency filter is a disposable consumable and cannot be cleaned.
Replacement cycle: Replace once every 6 to 12 months under normal conditions, or immediately when the pressure difference is ≥450Pa (twice the initial pressure difference).
Special scenarios: In industries with high cleanliness requirements (such as GMP workshops in the pharmaceutical industry) or when equipment operates 24 hours a day, the pressure difference should be tested every 3 to 6 months. If it meets the standards, the equipment should be replaced.
4. Fan/Electrical components
Fan impeller cleaning: Once a month (remove dust from the impeller surface to prevent dynamic balance imbalance);
Control cabinet cleaning: Wipe the internal dust with a dry cloth every month (do not use water or cleaning agents). In high-dust environments, do it once every two weeks.
Core principle
The core basis for judging the cleaning cycle is the operating status of the equipment and the amount of environmental dust.
Low dust and low frequency usage (such as in laboratories) : The cycle can be appropriately extended by 10% to 20%.
High dust and high-frequency usage (such as food processing and electronic manufacturing) : The cycle needs to be shortened by 30% to 50%, based on the pressure difference data and visual dust accumulation conditions.
