Explosion-proof filter for paint shops

Paint shops are a high-risk area. And when it comes to safety, especially in explosive atmospheres, the choiceexplosion-proof filterbecomes critical. Often, when choosing equipment, attention is paid only to explosion protection, forgetting about other key parameters such as filtration efficiency, throughput and, of course, compliance with the conditions of a particular production process. I would say this is a common mistake. From experience, simply having an explosion protection certificate is only half the battle.

Why are not all explosion-proof filters the same?

When a client contacts us with a request forexplosion-proof filterFor a paint shop, we always start with a thorough analysis. I’ll say right away that you shouldn’t take everythingexplosion-proof filtersas a homogeneous product. There are different types of filters - from simple lightning protection to multi-stage systems, including pre-filtration, aerosol removal and air recirculation. The differences relate to both the material of the filter element and the design of the filter. And the choice depends on many factors - the type of paint, particles formed during the painting process, the required degree of air purity and, of course, the safety regulations in force at a particular enterprise. Take, for example, the painting of metal surfaces. This requires more aggressive pre-filtration to avoid clogging the finer filters.

In my practice, there was a case when the customer choseexplosion-proof filterwith a nominal efficiency value of 99%. As a result, due to incorrect selection of filter element material, the filter quickly became clogged, significantly reducing the throughput of the system. The customer not only had to change filters more often, but also spend more time on servicing them. It turned out that this type of paint requires a filter with a different chemical composition that is more resistant to solvents and resins.

Key parameters when choosing a filter for paint shops

So, what should you pay attention to when choosingexplosion-proof filterfor a paint shop? Firstly, this is, of course, the degree of protection against explosion - explosion protection category (Ex), corresponding to the operating conditions. Secondly, filtration efficiency - how well the filter removes paint particles, aerosols, and solvent vapors. Thirdly, throughput - so that the filter does not create excess pressure in the system, which can lead to a decrease in painting efficiency and an increase in energy consumption. Fourthly, the material of the filter element - it must be resistant to the paints and solvents used. Finally, ease of maintenance - so that filters can be easily replaced and cleaned. We, at Tianjin Tongchang Junqi Cleaning Equipment Co.,Ltd, emphasize the importance of a holistic approach to selection, taking all these factors into account. Our company works closely with the Air Conditioning Research Institute of the China Institute of Building Sciences, which allows us to develop and produce efficient and reliable solutions.

Filter element materials

The choice of filter element material is a separate big topic. Typically polypropylene, polyester, and synthetic fibers are used. Each of them has its own advantages and disadvantages. Polypropylene is the most common and economical option, but it is less resistant to aggressive solvents. Polyester is more durable, but also more expensive. Synthetic fibers can be designed for a specific paint and solvent type to provide maximum filtration efficiency. We offer a variety of filter media options and help customers choose the best option for their specific needs.

Design and type of filters

Constructionexplosion-proof filteris also of great importance. There are different types of filters - cartridge, bag, cyclonic. Cartridge filters provide a higher degree of filtration but require more frequent maintenance. Bag filters are easier to use, but less effective. Cyclonic filters are used to pre-clean air from large particles. We offer various types of filters to suit the needs of any customer. Company ?Tongchang Cleaning? actively participates in the development of the national standard GB/T-13554 ?High-efficiency air filters? and constantly improves our technologies.

Errors during operationexplosion-proof filters

Incorrect operationexplosion-proof filters– this is another common reason for their premature failure. For example, failure to comply with filter replacement deadlines, use of unsuitable cleaning products, incorrect installation of filters. These errors can lead to reduced filtration efficiency, increased energy consumption, and even filter failure. It is important to strictly follow the manufacturer's recommendations for operating filters and carry out regular maintenance.

In our workshop we once had to deal withexplosion-proof filter, which suddenly stopped working. It turned out that the filters had not been changed for several months, and they were completely clogged with particles of paint and solvents. Replacing the filters and general cleaning of the system returned the filter to normal operation. But this was an expensive repair that could have been avoided if the manufacturer's recommendations had been followed.

Conclusion
