Why is filter cleaning important?
Some of the most common problems when cleaning filters with pulse jet systems are due to the poor quality of the compressed air, which is sometimes dirty, humid or with oil, which causes difficulties in correctly removing adhering residues to these.
At present, dust collectors bag type or cartridge type, implement automated cleaning systems, better known as pulse jet, which consists of expelling compressed air through a system of valves, these allow the exit of pressurized air to shake the filters and avoid their saturation, therefore we must make sure that the compressed air that will be used for this task is clean and dry, this will help prevent filtering problems, unnecessary stops of the collector, constant filter changes, delays in operation and possible damage to other components of the equipment.
What is compressed air?
“Air whose volume has been decreased by compression to be used when expanding“.
In industrial collectors, it is used for cleaning the filter box, thus avoiding their saturation.
Cleaning
The contaminants that accumulate on the surface of the filters, cause the differential pressure in the chamber to increase, this means that when the pressure reaches the established limit, a pressure switch activates the sequencer, this in turn sends a signal to the solenoid valve so that it opens and releases the pressure that is holding the diaphragm valve.
The opening of the diaphragm valve allows the clean and dry compressed air to be expelled in the form of a jet, this penetrates the filter and creates a downward and radial air stream towards the rest of the cartridges, with this it is possible to remove the accumulated dust on them.
Humidity Hazard
Due to the humidity loaded in the environment, it can penetrate into the compressor. During compression, 7.8 ft³ atmospheric air, is reduced to 1 ft³ compressed air at 100 psig. The air concentration increases the humidity, in this case by a factor of 7.8: 1, which will saturate the air if the relative humidity is greater than 12.8%.
As compression increases the air temperature, this level of humidity is not a problem at first, but as the compressed air circulates into the dust collector, the air cools and condenses, this causes it to mix with dust and creates a muddy film that affects the performance of the filters and decreases the filtering capacity.
Oil Hazard
Another important factor to take into consideration is that the compressed air is contaminated with oil, which will cause some difficulties; the combination of compressed air with oil and dust can form a thick layer of dust on the top of the filter; also these can break and cause their detachment from the base.
Risk of clogging due to dirt
In addition to the aforementioned factors, it is very important to take into account, the dust particles in the compressed air, these can get lodged in the outlet holes of the Solenoid valves or diaphragm, so this would prevent the valves from closing quickly and allow the passage of additional air not contemplated, and therefore causes the filters to be over cleaned and damaged.
How to prevent compressed air from damaging the filters?
There are some accessories that can prevent compressed air contaminated with dirt, moisture or oil from reaching the filters, such as traps, air filters, oil filters and dryers.
Detecting any of these and other problems in your industrial dust collector in time will prevent more advanced damage in the short term, if your company has this or other problems with its equipment, contact us to analyze the situation and find out what would be the best solution.

How to select a bag type filter?
The performance of the bags or sleeves depends closely on the materials with which it is manufactured, as well as other factors. Choosing the right filter for a Dust Collector is very important, since the efficiency of capturing the particles depends on this and that the equipment has optimal performance during its operation.
Filtration speed
It can be defined as the proportion of air that passes through the filter cloth, that is, the amount of air that passes through each square foot of the filter media area per minute.
Is it important to measure air speed?
Before carrying out a project for the control of dust, fumes, mists or gases in the company, you must collect as much information and data that will allow you to carry out the correct and necessary calculations, one of the most important is that of the Speed of the Air or CFM.
