Atlas Copco Compressed Air Filters: Precision Filtration for Every Application

Clean, dry compressed air is essential for protecting equipment, ensuring product quality, and meeting regulatory standards. At Air Kraft, we supply the complete range of Atlas Copco compressed air filters, each engineered for high performance and efficiency. Whether your application requires basic particle removal or high-purity, oil-free air, we can help you choose the right filter combination to meet your air quality requirements.

Understanding Atlas Copco Filter Grades

Atlas Copco’s filter range is designed to remove contaminants such as dust, oil aerosols, vapours, and moisture at different filtration levels. Key models include:

DD+ Filters - General Purpose Particle and Coalescing Oil Aerosol Removal

Removes solid particles down to 1 micron
Residual oil content: ≤0.5 mg/m³ (0.1 ppm)
Ideal as a pre-filter to protect downstream filters and dryers

PD+ Filters - Fine Coalescing Filter

Removes particles down to 0.01 micron
Residual oil content: ≤0.01 mg/m³
Used in critical applications requiring high air purity

UD+ Filters - Dual Element Filter, Combines the DD+ & PD+ in One Housing

Saves space
Saves money

QD+ Filters - Activated Carbon Filter

Removes oil vapours and hydrocarbons
Residual oil content: ≤0.003 mg/m³
Installed downstream of PD+ filters to meet ISO 8573-1 Class 1 oil standards

DDp+ / PDp+ Filters - Dust Particle Filters

Installed downstream of desiccant dryers
Capture desiccant dust and fine particles
Ensure consistent air quality in high-purity or sensitive processes

QDT Activated Carbon Towers

Designed for bulk removal of oil vapours and odours
Typically used in food, beverage, and pharmaceutical industries where oil-free air is essential

Matching Filters to Applications

Different industries require different levels of compressed air purity. Here's how the filters are typically applied:

Application	Typical Filter Setup
General Industrial (pneumatics)	DD+ & PD+
Automotive Spray Painting	DD+ &+ PD+ & QD+
Food & Beverage (non-contact)	DD+ & PD+ & QD+
Pharmaceutical (contact air)	PD+ & QD+ & QDT
Electronics / Cleanroom	PD+ & QD+ & Dust Filters (PDp+)

Each filter serves a purpose, and the correct combination ensures compliance with ISO 8573-1 standards, protects downstream equipment, and prevents contamination of end products.

The Importance of Site Conditions

It’s critical to consider site-specific reference conditions when selecting and sizing filters. Ambient temperature, humidity, inlet pressure, and air temperature can significantly impact:

Filter efficiency
Oil and moisture removal performance
Pressure drop and flow rate

For example, higher temperatures can reduce the effectiveness of coalescing filters, while lower pressure increases air velocity, affecting filtration performance. This makes correct sizing and installation essential for ensuring consistent air quality and maintaining energy efficiency.
