AE Alkaline-impregnated Coconut Shell Carbon – Organic Vapor & Acid Gas Protection

Key Features

• Organic & Acid Gas Dual Function

  Effectively adsorbs benzene series organic vapors, and neutralizes acid gases such as sulfur dioxide, hydrogen chloride and hydrocyanic acid.

• Alkaline Impregnation Formula

  Uniform loading of alkaline active components with high acid gas absorption capacity and long breakthrough protection time.

• High Mechanical Strength (>95% hardness)

  Low wear and dust generation, maintains stable bed resistance under long-term airflow scouring.

• Standard Particle Size Options

  Available in 8×16 mesh (1.18–2.36 mm) and 12×20 mesh (0.85–1.70 mm), compatible with various filtration devices.

Applications

• Acid Gas Workplace Respiratory Hazard: Pickling, electroplating and chemical synthesis operations generate SO₂, HCl and HCN that standard carbon cannot reliably capture. AE's alkaline impregnation chemisorbs these acid gases through neutralization reactions while maintaining organic vapor adsorption capacity.

• Mixed Organic & Acid Gas Treatment: Workspaces where organic solvents and acid gases coexist create dual-contaminant challenges. AE's dual-mode design handles both contaminant types in a single bed, simplifying system design versus separate media configurations.

• Industrial Acid Waste Gas Purification: Exhaust streams containing sulfur dioxide and hydrogen chloride require reactive media, not just physical adsorption. AE's alkaline-impregnated surface converts acid gases into stable salts, preventing breakthrough that would occur with standard activated carbon.

• Laboratory Fume Hood Protection: Fume hood exhaust containing mixed acid and organic vapors threatens operator safety. AE provides dual-function purification, removing both acid gases and organic compounds before atmospheric discharge.

Technical Advantages

• Dual design of physical adsorption plus chemical neutralization extends protection time in acid-gas scenarios compared to standard activated carbon.

• High-quality coconut shell base with developed micropores maintains excellent organic gas adsorption while removing acid gases.

• Stable impregnation process with low reagent shedding avoids secondary powder entrainment pollution.

• Protection performance tested according to national respiratory protection standards for reliable safety indicators.

FAQ

Q: What is the protection time of AE against sulfur dioxide?

A: Breakthrough protection time is ≥35 min for SO₂ and ≥65 min for cyclohexane under standard test conditions. Actual service life varies with gas concentration and airflow rate. For higher acid-gas loads, consider PFH-E with its enhanced alkaline loading.

Q: Can AE be used for ammonia protection?

A: AE is designed for organic vapors and acid gases, with limited effect on alkaline gases like ammonia. For ammonia scenarios, we recommend PFH-K or the comprehensive ABEK grade.

Q: How do I know when to replace AE?

A: Replace immediately if odor is detected or breathing resistance increases significantly. For fixed installations, schedule replacement based on operating time and gas concentration monitoring.
