In construction, renovation, and demolition activities. cutting, grinding, drilling processes will involve concrete. Concrete is composed of cement, sand, gravel, and water, and when these components are manipulated or disrupted, tiny particles can become airborne, creating concrete dust.Concrete dust consists of tiny particles that can vary in size. It may include both larger, visible particles and finer particles that are respirable and can be inhaled into the lungs.
For this reason, many customers will use their equipment with vacuum cleaners during construction. According to the filtration level, there are singe stage filtration and 2-stage filtration vacuum cleaners on the market. But when it comes to buying new equipment, customers don't know which one is better.
One-stage dust collectors are relatively straightforward in design and operation.consists of a motor that pulls the contaminated air into the collector, where a filter (often a bag or cartridge filter) captures the dust particles. Like Bersi S3,DC3600,T3,3020T,A9,AC750,D3. A Two-stage filtration systems dust extractor vacuum often have a higher upfront cost. In the first stage, the pre filter is often used to remove larger and heavier particles from the airflow before it reaches the main filter.The second stage involves a finer HEPA 13 filter with filter efficiency >99.95%@0.3um to capture smaller particles that may have passed through the primary stage. Bersi TS1000,TS2000,TS3000,AC22,AC32 and AC900 are all 2-stage filtration industrial vacuum cleaner.
Take 3020T and AC32 as an example, both these 2 models are 3 motors ,with 354cfm and 100 water lift, auto clean. 3020T equipped with 2 pcs filter take turns auto clean.AC32 has 2 pcs filter in primary same as 3020T,and 3pcs HEPA 13 filter in the secondary.
With the same airflow and water lift ,due to differences in design structure and manufacturing costs, concrete vacuum cleaners with two stages of filtration are generally more expensive than those with one stage of filtration. Customers will think twice about whether it is necessary to spend more money to purchase a secondary filtration machine when making a choice.
Here are some considerations to help you determine if a two-stage filtration system is necessary for your situation:
1.Type of Dust
If you are dealing with fine dust particles, especially those that may pose health risks (such as silica dust), a two-stage filtration system with pre filter can be beneficial. The pre filter stage helps capture larger particles, preventing them from reaching and clogging the main filter.
2.Regulatory Compliance
Check local occupational health and safety regulations. In some project, there are specific regulations regarding airborne particulate matter, and using a two-stage filtration system may help you meet or exceed compliance standards.
3.Health and Safety
If the dust generated in your operations poses health risks to workers, investing in a more efficient dust extraction system, such as a two-stage system with fine particle filtration, is a proactive measure to protect the health and safety of your workforce.
In summary, if your budget allows, a two-stage system dust extractor with H13 filter is your first choice if you are workers in in construction, masonry, concrete cutting, and related industries which are particularly at risk of exposure to concrete dust. Sometimes the initial investment in a higher-quality system pays off over time.
