Filtration & Purification

In compressed air systems, FILTRATION is an essential part of the quality and safety of the entire system. For this reason, NARDI COMPRESSORI develops solutions designed for up to 420 bar (6000 psi), to treat air in a progressive and controlled way, acting on humidity, particles, oil residues, vapors, odors and specific contaminants.

When compressed air is intended for breathing — in diving, HOOKAH systems, SCUBA/SCBA, SAR and professional applications — air quality is not just a technical performance. It is a responsibility.

STANDARD AND SUPPLEMENTAL FILTRATION SYSTEMS

Atlantic & Pacific Compressor Filters

This page covers integrated filtration systems for our Atlantic and Pacific compressor lines, plus supplemental filter packages that mount to rigid surfaces. Standalone packages are available in single and multi-stage tower designs.

​

Our high-performance, post-compression filter towers and cartridges are designed to deliver clean, dry high-pressure air by removing oil, moisture, and other contaminants with modular sizing to match your compressor or booster flow rate demands. Each filter includes a maintenance valve that maximizes air contact time with the purification media, helping ensure compliance with DIN EN 12021:2014 and ISO 8573-1 requirements for breathing air and other industrial/professional gases.

​

Our standard compressor filter cartridges feature rugged all-aluminum body and a multi-stage media pack that includes:

• Felt pre-filters to capture larger particles

• Molecular sieve to remove water vapor

• Activated carbon to reduce oil vapors and odors

• Hopcalite (optional) to convert CO to CO₂

To protect performance over time, every cartridge is decontaminated, sealed, and vacuum-packed, preserving the drying media from external contamination until installation. Choose from our ATL, PAC1, PAC2, and PAC3 filter towers and cartridges.

SPECIALIZED FILTRATION SYSTEMS

NF-A · Nardi Filter - Aseptic

Designed for maximum outlet air purity using a simple, safe approach: compression heat plus high-efficiency antibacterial filtration, capturing particles down to 0.01 microns to support sterile air delivery—without ozone or UV-C exposure risks.

NF-OF · Nardi Filter - Antibacterial

Antibacterial purification filters designed to achieve ISO 8573-1 Output Air Purity Class 1.7.2, using a microfibre coalescence cartridge element to separate and remove liquid and solid particles (available in multiple flow capacities).

Filter Dryer Series

Dental and medical dryers installed between the pump unit and air tanks to deliver consistently dry, odor-free air with low dew point performance (desiccant and membrane-based options).

CHILLER · High-Pressure Refrigerated Air Dryer

A high-performance refrigerated dryer cools high-pressure compressed air to near 32°F (0°C) to remove up to 98% of moisture before filtration—reducing cartridge load and extending service life.

SPECIALIZED SANITIZING SYSTEM

Sany-Air Sanitizing Nebulizer

A purpose-built system for rapid, professional surface sanitizing using fine-mist nebulization—ideal where fast coverage and turnaround matter.
