YIDINGAIR FILTRATION
Product overview
What it is and where it fits.
The AR104 stainless steel filter uses several crisscrossed layers of corrugated stainless mesh, reinforced by crossbars on both faces. The all-metal construction withstands heat, moisture and repeated washing, making it a long-life prefilter for industrial ventilation.
The catalogue lists 71.5% gravimetric efficiency for the 1-inch version and 81.3% for the 2-inch version, with low initial pressure drop. Standard modules and customer-specified sizes are available.

Construction & performance
Construction
Multiple crisscross layers of corrugated stainless steel mesh increase filtration area. Crossbars reinforce both faces for industrial ventilation use.
Maintenance & sizing
All-stainless construction can be washed and maintained for reuse. Standard and customer-specified dimensions are available.
Selection guide
How to choose.
Stainless or aluminium
Stainless steel resists corrosion and stronger cleaning agents; our all-aluminium version is lighter for the same modules.
1-inch or 2-inch
The 2-inch version has higher efficiency and dust-holding capacity at a slightly higher pressure drop.

Common questions.
How do I clean a stainless steel air filter?+
Wash it with water and a mild detergent, or blow it out with compressed air, then let it dry before reinstalling. The all-stainless construction tolerates repeated cleaning.
What is the difference between the stainless and aluminium versions?+
Both are washable metal filters in the same sizes. Stainless steel is stronger and more corrosion-resistant; aluminium is lighter and lower in cost.
