Product Description

Product Description

The 220C G4 500*500*20mm High Temperature Resistant Aramid Panel Filter is engineered for industrial ventilation systems requiring reliable pre-filtration under elevated temperatures.

Constructed with high-performance aramid synthetic fibers through non-woven lamination technology, this panel filter delivers stable G4 class efficiency at sustained 220°C operation. The aramid media offers exceptional thermal stability with only 1% shrinkage at 250°C and withstands short-term exposure up to 300°C without softening or melting.

For buyers in chemical plants, thermal power stations, cement factories, and paint spray booths, this product solves critical challenges: removing coarse particulates from high-temperature air streams while resisting corrosive fumes and providing inherent flame retardancy.

The lightweight panel design ensures easy installation and replacement, reducing maintenance downtime. This High Temp Aramid Panel Filter maintains dimensional integrity and filtration performance throughout its service life, protecting downstream equipment and extending overall system longevity.

Product Features

The 220C G4 High Temperature Resistant Aramid Panel Filter delivers distinct advantages through its specialized aramid fiber construction. The following features demonstrate its value for demanding industrial applications.

1. 220°C Continuous Heat Endurance
The aramid media operates at 220°C without aging or embrittlement. Thermal shrinkage is only 1% at 250°C. Short-term 300°C exposure causes no softening or melting, ensuring reliable performance in fluctuating temperature environments.

2. Excellent Flame Retardancy
The media is self-extinguishing and non-combustible. It does not support combustion, just produces minimal smoke during fire exposure, and naturally carbonizes without melting or dripping. This enhances safety in high-risk industrial settings.

3. Strong Chemical Resistance
The aramid fibers resist acids, alkalis, and corrosive fumes common in chemical processing, metallurgy, and waste incineration applications, ensuring long service life in harsh environments.

4. Customizable Frame and Dimensions
Available in aluminum or galvanized steel frames with fully customizable dimensions to fit specific AHU housings. Mesh cover (single or double-sided) is optional for enhanced media protection.

5. Stable Dimensional Integrity
The media maintains flat panel shape under thermal cycling. No curling, warping, or media compaction occurs during operation, ensuring consistent filtration performance.

Product Applications

The 220C G4 High Temperature Resistant Aramid Panel Filter performs effectively across diverse high-temperature industrial environments. As a G4 Synthetic Fiber Filter, it excels as a pre-filtration solution in multi-stage systems.

1. Chemical Processing Plants
Removes coarse dust and particulates from high-temperature exhaust streams. The aramid media resists corrosive acid and alkali fumes that would degrade standard synthetic filters, ensuring stable operation in aggressive environments.

2. Thermal Power Stations and Cement Plants
Captures fly ash and coarse particles from flue gases at elevated temperatures. The self-extinguishing feature enhances safety in high-dust, high-heat conditions where fire risk is a concern.

3. Paint Spray Booths and Drying Ovens
Serves as pre-filter upstream of medium/high-efficiency filters. The low initial pressure drop reduces fan energy costs while protecting downstream filters from premature loading. The flame retardant media adds an essential safety layer in solvent-rich environments.

4. Metallurgy and Smelting Facilities
Filters hot air intake in furnaces and kilns. The aramid media withstands thermal shocks and chemical exposure, providing reliable pre-filtration that extends the service life of downstream equipment .

5. Waste Incineration and Boiler Systems
Removes coarse particulates from combustion air and flue gas. The media's thermal stability and chemical resistance ensure long service intervals in demanding high-temperature applications where maintenance access is limited.

6. Asphalt and Carbon Black Production
Filters hot process air containing sticky, abrasive particulates. The non-woven aramid panel captures these particles without media blinding or degradation, maintaining airflow and reducing change frequency.
