You will find a huge number of OEMs making dust extractor filler bags in the market. Models made by one are quite different from another. Since there are a huge number of designs and configurations to choose from, you may find it a bit difficult to select a particular type. It would be helpful if you contact experienced companies for this equipment filler bags of only the right size will be able to deliver optimal performance.
Factors to decide the most suitable dust extractor filter bag
The following properties will help you choose the best dust extractor filter bags for your requirement:
- Dust load
- Work environment at the industrial operation
- Temperature requirements
- Dust properties
When you visit the website of a reputed manufacturer and look at the brochure of different bag models, you would be scoring the bags as per the above characters.
Clean filter bags easily
A fine layer of dust works well to trap small dust particles within the bag’s filter. On the other hand, a thick layer of dust within the bag may compel you to dump it into the laundry. You can, however, try the following methods to remove dust before putting it into the machine:
- Keeping the bag inflated with the running dust collector, you can tap the bag with a broomstick or your own hand
- Blow compressed air against the bag’s exterior while keeping the collector running
- If still not happy, you turn the bag inside out and vacuum the remaining dust from it
Tips for maintenance of filter bags
For the efficient functioning of a dust collector filter bag, you will need to carry out periodic inspections. These inspections may be followed by replacement or repair of non-functional equipment. The following procedure will help you keep the filter bags in good condition for a number of years:
- Put a periodic inspection program into place– You may prefer weekly, daily or monthly inspections or a combination of a few of these. Such programs will ensure that you get peak performance from the filter bags on every use.
- Do not go beyond the recommended pressure drop– This is the measure of static resistance around resistors while operating a positive or negative pressure collector. Pressure drops are indicative of the amount of dust that accumulates on filters. New filters face the minimum pressure drops, while this drop can increase if a dust cake develops inside.
- The cleaning system should function properly– Different types of cleaning systems are used to remove dust cakes from the filters. These systems include shaker, pulse clean or reverse air. In the absence of a proper cleaning system, dust will build on to the bags. As a result, pressure drop will become high and there shall be less volume of ventilation air at the designated pick up points.
- Keep a lookout for emissions– This is inclusive of any form of a particulate matter which may be seen emanating from the exhaust stack. This may happen due to a broken filter or a break in the seal. The leak could not only be harmful to the environment and people around, but may also result in fines by environmental agencies. At times, even fans downstream from the collector can get damaged as a result of abrasion.
- Choose the most suitable exhaust fan– Ventilation air can only be circulated from around the pickup points with the help of an exhaust fan. Fans are chosen as per their abilities to regulate pressure drops and to accommodate volume.
- Keep a check on the filter media– This is the one which supports a dust cake within the collector. High filtering efficiencies are possible due to the dust cake. The clean side of the dust collector should be regularly inspected for leaks, while the bags must similarly be checked for leaks.
Many of today’s dust collector filter bags can easily be fitted into the existing collectors, as a result of which more air can pass through every bag. Top features of filter bags are:
- Parts that can be easily removed
- Very low maintenance cost
- Low downtime
- Less consumption of air
- Synthetic parts that make filter bags resistant to abrasion
- A much larger filter area in comparison to traditional bags
Strict quality guidelines followed at all times
Each of the dust collector filter bags is made from high-quality raw material such as base fiber. From the time of raw material procurement to the end product, the best companies ensure adherence to quality standards at every stage. The best stitching machines are used to create these filter bags as per client requirements. The range of fabric media offered by them includes:
You will find these bags being used in industries such as power stations, boilers, steel, cement, ceramic, and others.
