Gardner Denver GDF013L3/4”V compressed air filter (Grade V)

Gardner Denver — a global leader in the manufacture of compressed air systems and treatment solutions — presents the GDF Grade V filter series, specifically engineered to remove oil vapors and hydrocarbon odors. This is the final stage of air preparation, essential for industries with the highest purity requirements, such as food processing, pharmaceuticals, and high-quality painting.

Grade V — activated carbon adsorption. These filters ensure the removal of oil vapors and odors, guaranteeing a maximum residual oil content of <0.003 mg/m³.

Design Features

• Cast Aluminum Housing

The housing is manufactured using high-pressure die-casting from a premium aluminum alloy, ensuring a lightweight yet robust design. The precise engineering guarantees a perfect fit for the carbon element, eliminating any risk of unfiltered air bypass.

• Corrosion Protection

The housing is protected by anodizing and an additional internal polymer coating. This is crucial for maintaining the absolute purity of the air stream and preventing any internal contamination.

• Manual Drain

Grade V models are equipped with a manual drain valve. Since this grade processes gaseous contaminants, liquid condensate should not be present in a properly maintained system; however, the valve allows for periodic system health checks.

Operating Technology (Adsorption)

Unlike mechanical filtration, Grade V operates at the molecular level:

1. Adsorption Process: Compressed air passes through a deep bed of high-capacity activated carbon. Oil molecules and odors are "trapped" on the surface of the carbon’s micropores.

2. Carbon Dust Filtration: An internal textile layer within the element prevents any carbon particles from being carried downstream into the air system.

3. Final Result: The air becomes completely odorless and technically pure from oil vapors, ready for critical applications.

   
   

Key Advantages

• ✅ Highest Purity Level: Reduces oil vapors to a residual content of <0.003 mg/m³.

• ✅ Minimal Pressure Drop: The optimized structure of the carbon cartridge ensures high efficiency with minimal energy loss.

• ✅ Product Quality Assurance: Prevents unwanted odors and tastes from affecting the final product.

  
  

Installation Recommendations (IMPORTANT)

To ensure the correct operation of the Grade V filter, it must be installed:

• ONLY after a Grade H filter: This is a mandatory requirement. The air entering Grade V must be pre-purified of solid particles and liquid oil aerosols. Without a Grade H pre-filter, the carbon element will fail almost immediately.

• As close to the point of use as possible: To prevent any potential re-contamination of the air within long piping runs.
