Filtered air
Filtered air.
In engineering. Description of the air filter will speak
Performance (Efficiency) measuring the ability of removing dust from the air.
Ability to collect dust (Dust holding capacity) means the quantity of dust that the air filter. Can be stored.
The aura of the crowd charity (Air flow resistance) is the value of pressure fall (Static pressure drop) through the air filter.
Speaking about the size of dust, exhaust, which is a unit measure Micron (Micron) the size of dust hanging in the air is 0,001 to 1 micron size (size of the dust seen by naked eye is 10 microns) and size of the exhaust. equal to 0.01 to 1 micron air filter, so they can trap dust and exhaust these must be really good performance.
For measuring performance. Will have different test methods. Standards of institutions such as ASHARE, AFI. NBS test method by which it is used.
How to weigh the test (Weight Test), using synthetic dust. Filtered air through a test. Tend to experiment with low efficiency air filters (car used to test this filter)
Dust Spot efficiency test method by water, dust filtering through the atmosphere. Then determine the rate of light illuminates. This applies to high-performance air filter.
DOP Penetration group method using vapor of DOP (Di-Octyl Phthalate) and then measure the scale of dark dust DOP test uses high-efficiency air filters.
In addition, the air filter used with car Divisible:
Dry type air filter (Dry Type) is a type. Synthetic fibers, plant fibers, wool is often used disposable type. Because of cheap And designed to be used in time … .. one that came with the air filter is a type vehicle.
Type air filter that is coated with a sticky substance. For example, spray with oil. To filter the air. The viscosity And increased ability to train to better capture dust. This type of filter is known to those who use the car brand is K & N, which can be used several times after cleaning cleaning And coating capability.
Why is recommend. Clean air-filter type use disposable??
In order to save costs. Before you change the air filter. We can extend the use of air filtration. By 2 o’clock in the ability to store the ordure of the air filter that is removing the old dust filters restrict air. To filter the air to capture new ordure. The air filter is not clogged. It also allows air to filter through easily. This helps in saving fuel. ???? course of the performance air filter. Will be reduced to?
What users want to know every car is Suggestions from the manufacturers are correct. Since the tests came in, but use a different vehicle can be used to study Or appropriate. To be adaptable.
