Activated Carbon Filter for PSA Nitrogen Generator

FLT Series - Protect Your Adsorbent, Ensure Ultra-Clean Compressed Air

Product Overview

The FLT Series activated carbon filter is engineered for terminal-stage purification in high-purity PSA nitrogen generators, medical-grade PSA oxygen generators, and membrane gas separation plants. Its primary role is to protect the molecular sieve adsorbent from oil vapor contamination, which significantly extends adsorbent life and maintains system performance.

Key Selling Points

• Ultra-Low Residual Oil: Output oil content <0.003 mg/m³, ensuring ultra-clean air for optimal adsorbent performance.
• High-Density Activated Carbon: Column-shaped granules provide large-capacity adsorption of oil vapor and VOC impurities.
• Low Pressure Loss: ≤0.02 MPa, minimizing energy consumption of the air compressor.
• Multi-Layer Graded Filling: Prevents air-flow short-circuit, ensuring stable purification efficiency.
• Easy Maintenance: Granular carbon filler is low-cost and simple to replace.
• Anti-Powder Leakage: Baffle-plate design prevents carbon dust from entering downstream equipment.

Customization

We offer customization in terms of material (carbon steel or SS304), working pressure up to 3.0 MPa, and flow rates to match your existing system.

Case Study

Supplied to a distributor in Pakistan for oxygen-enriched combustion in blast furnaces, achieving stable operation over 5 years with consistent oxygen purity and flow rate.

FAQ

What is the function of an activated carbon filter?

It removes oil vapor and VOC impurities from compressed air, protecting downstream molecular sieve adsorbents.

What is the residual oil content after filtration?

The output oil content is less than 0.003 mg/m³.

What is the pressure loss across the filter?

The pressure loss is ≤0.02 MPa, minimizing energy consumption.

Can the filter be used for high-pressure systems?

Yes, a high-pressure version up to 3.0 MPa is optional.

How often does the activated carbon need replacement?

Replacement frequency depends on inlet oil load and operating hours. The granular carbon is low-cost and easy to replace.

What materials are available?

Carbon steel and SS304 are standard options.
