The resistance of the corresponding filter scrap value "end resistance. Choice of final resistance has a direct bearing on the life of the filter. Under normal circumstances, the final resistance of selected air conditioning designer. Experienced engineers can be changed according to the situation of the original design of the final value of the resistance. The filter formed airflow resistance. Y type filter fouling resistance increased scrapped when the resistance increases to a specified value, the Y type filter.

The filter reaches final resistance could mean immediately replace the filter could also mean that the plan to do tomorrow, next week, or next month to replace the filter. Users provincial judge look at the final resistance depends on site-specific requirements and operating experience.

In most cases, the site Y type filter final resistance is 2 to 4 times the initial resistance. But the gap between the low efficiency of the filter material fiber disperse the fouling on too much resistance will filter to strictly limit the final resistance value of the G4 filter. Changes in the scope of the system air volume, the energy consumption of the system.nylon mesh

Comfort air conditionin g system uses only a low efficiency filter, occur within a few years tuyere black stains fade walls, air conditioning systems fouling. The cost of dealing with these issues is amazing, these lessons will improve the efficiency of the filter specifications in the new design, while others have to choose only from the health point of Y type filter. Cities in the comfort of air-conditioning systems in order to put an end to the outlet black stains, to maintain interior decoration does not fade, and keep the air conditioning system and the air supply pipe clean the best selection of F7 efficiency specifications (colorimetry 85% of, China Specifications High efficiency) filter devices.

In many projects, user requirements as much as possible to narrow the space of the air conditioning system, users did not notice in the lower prices suppliers use a small filter area cheap Y type filter. To meet the requirements of air purification filter works acceptance, but due to the small size of filter filter = material, will not long filter life. Pre-Y type filtration efficiency of the filter can be adjusted to block the dust in the pre-filter. For example, the end of the filter is F7, G4 pre-filter [www.kfshjx.com] end of the life of the filter is 3 months, switch to the end of the filter after pre-F5Y type filter life extended to six months.
