[WHAT TO GET] Made of polyurethane material, it has a soft and elastic texture, is corrosion-resistant, and its pores are evenly distributed and interconnected. It not only provides a structural foundation for dust prevention, filtration, and sound absorption, but also ensures good breathability to avoid poor heat dissipation of equipment caused by filtering materials obstructing airflow.
This sponge filter is not easily ignited when exposed to open flame and can self-extinguish once the fire source is removed , effectively reducing the fire risk of some equipment such as air compressors and frequency converter chassis.

[WHEN/WHERE TO USE] This dust-proof filter sponge is based on a multi aperture structure and can achieve dust-proof, filtering, and sound-absorbing functions. It also has flame retardant properties and can provide safety protection and ensure stable operation for equipment. It suitable for air compressors, inverter chassis, vacuum cleaners, exhaust fans, audio equipment, and other devices.

[WHAT IT IS] Size: 30 x 20 x 0.3 cm / 12 x 8 x 0.12 inch (L x W x T); Material: Polyurethane; Color: Black; Package List: 10 Pcs x Fan Replacement Filter.

[HOW TO USE] When in use, scissors can be used to accurately cut according to the actual size of the filter slot, and then the sponge edge can be tightly attached and fixed to the filter slot.

[WHAT TO AVOID] Although it has flame retardant properties, it should not be directly exposed to open flame or placed in high temperature environments exceeding 110℃, otherwise it may cause the sponge to lose its flame retardant and protective properties.
