Maintenance of Purification Equipment in Animal Laboratories: Tips for Extending Service Life

In animal laboratories, purification equipment is crucial for ensuring a stable experimental environment and reliable experimental results. As a professional manufacturer of purification equipment, Guangzhou Cleanroom Construction Co., Ltd. deeply understands the importance of the stable operation and long - term use of equipment. Today, we will share some practical tips on maintaining purification equipment in animal laboratories and extending its service life.

For the High - Efficiency Particulate Air (HEPA) filter, regularly clean the visible dust on its surface. Although it has a strong filtering capacity, excessive dust accumulation on the surface will affect the air intake efficiency and indirectly increase the operating burden of the equipment. You can gently sweep away the surface dust with a soft brush. Note that the equipment power should be turned off during the operation to prevent accidents. The activated carbon filter also needs to be cleaned regularly to maintain its performance of adsorbing odors and harmful gases. It can be taken out, rinsed with clean water, and then dried naturally. However, avoid exposure to sunlight to prevent affecting the adsorption effect of activated carbon.

After each use of the experimental animal disinfection transfer cabinet, promptly clean the remaining debris inside and wipe the surface of the cabinet with a disinfectant to prevent cross - contamination. This can also keep the equipment clean and hygienic and extend its service life. During the use of the bedding collection station, a large amount of dust and bedding debris will accumulate. Regularly empty the collection container and clean the tabletop and its surroundings to prevent dust from blocking the ventilation openings of the equipment and affecting its normal operation.

Inspect the air ducts of the ventilation system monthly to check for air leakage. If the joints of the air ducts become loose, the purified air will leak, affecting the overall purification effect in the room. At the same time, it will also make the fan and other equipment work extra, increasing energy consumption and equipment wear. Once air leakage is detected, promptly seal it with sealant. In addition, check the air disinfection equipment, such as whether the lamp tube of the ultraviolet disinfection lamp is blackened or damaged. If the lamp tube ages, its sterilization ability will be greatly reduced, and a new lamp tube needs to be replaced in a timely manner to ensure the disinfection effect.

Regularly check whether the safety devices such as the safety valve and pressure gauge of the high - temperature steam sterilization equipment are working properly. If the safety valve fails, it cannot relieve pressure in a timely manner when the internal pressure of the equipment is too high, which may lead to a safety accident. If the pressure gauge is inaccurate, it will be difficult to judge the pressure state during the operation of the equipment, affecting the sterilization effect. For these key components, professional testing institutions can be commissioned to calibrate and test them regularly to ensure the safe and stable operation of the equipment.

The HEPA filter is the core component of the air purification equipment, and its service life is directly related to the effect of the entire air purification system. Generally, under normal use conditions, it is recommended to replace the HEPA filter every 1 - 2 years. However, if the environment where the laboratory is located is poor, or the breeding density of experimental animals is high and a large amount of pollutants are generated, the replacement cycle should be appropriately shortened. When replacing the filter, pay attention to choosing a product that matches the equipment model to ensure correct installation and avoid gaps that will greatly reduce the filtering effect.

The fan is the power source of the ventilation system. Regularly adding lubricating oil to the fan can reduce the friction resistance during its operation, reduce energy consumption, and also extend the service life of the fan. In addition, check whether the fan belt is loose or worn. If there are any problems, adjust or replace it in a timely manner. A loose belt will cause the fan speed to be unstable, affecting the air volume. If the belt is severely worn, it may break suddenly, causing a failure of the ventilation system.

The purification equipment in animal laboratories is relatively complex, involving multiple professional fields such as air purification, disinfection, and waste treatment. Guangzhou Cleanroom Construction Co., Ltd. has a professional technical team that can provide customers with comprehensive equipment maintenance services. We recommend that customers regularly contact the manufacturer for in - depth maintenance and upkeep of the equipment, such as comprehensive inspection of the equipment, software upgrade (for some intelligent equipment), etc. Our technical personnel have rich experience and can accurately judge potential problems of the equipment and solve them in a timely manner, keeping your purification equipment in the best operating condition at all times.

Maintaining purification equipment in animal laboratories is not a one - time task. It requires daily careful care and regular professional maintenance. By following these maintenance tips, not only can the service life of the equipment be extended and the equipment renewal cost be reduced, but also a stable and clean experimental environment can be continuously provided for animal laboratories. If you have any questions during the equipment maintenance process, Guangzhou Cleanroom Construction Co., Ltd. is always at your service to help your scientific research work proceed smoothly.
