Product Definition
Filtration efficiency
Extend surface plate medium filters with metal backing meets the medium-efficiency filter standard (such as MERV 10-16, or European standard F7-F9).
Covering mesh design
The surface is covered with a protective mesh to enhance the structural strength and prevent the filter material from being damaged.
Pleated (pleated) structure
The pleated design increases the filtration area, reduces wind resistance, extends the service life, and increases the dust holding capacity.
Material
The filter material is synthetic fiber, and the outer frame can be made of aluminum alloy, galvanized steel plate or cardboard frame.

Production Flow Chart

Maintenance and care
Regular inspection
Check the filter regularly to see if the filter is damaged or deformed, if the cover is loose or damaged, and if the filter material is blocked or contaminated. If any problems are found, they should be promptly handled or replaced.
Cleaning and replacement
Clean or replace the filter regularly according to the use and environmental conditions of the filter. Generally speaking, when the resistance of the filter reaches a certain value, it means that the filter is blocked and needs to be cleaned or replaced. When cleaning, you can use compressed air or clean water to rinse the filter material, but be careful to avoid damaging the filter material. If the filter still has poor filtering effect after multiple cleanings, or the filter material is damaged, you need to replace it with a new filter.
Storage environment
When storing the filter, extend surface plate medium filters with metal backing should be placed in a dry, well-ventilated place to avoid moisture, contamination or mechanical damage to avoid affecting the performance and service life of the filter.
