Felt kit for Maxifilter and Hyperfilter cartridges

The Coltri Felt Disc Kit is a set of original spare parts essential for the correct maintenance and perfect functioning of breathing air purification systems on Coltri compressors.

Felt discs play a crucial mechanical action within the filter cartridge: retaining micro-particles, carbon residues, and oil emulsions before the air reaches the diving cylinder. Regular replacement of the felts during the change of molecular sieves and activated carbon ensures purified, odorless recharged air that complies with the strictest safety standards (EN 12021).

Key Features and Technical Specifications:

• Original Coltri Spare Parts: Produced with high-density materials and perfect geometric tolerances to ensure maximum retention efficiency without impeding the compressor's airflow.
• Progressive Mechanical Filtration: Captures coarse impurities and residual moisture, protecting the underlying chemical filtering materials and extending their operational life.
• High-Pressure Resistance: Non-deformable structure designed to work constantly at high operating pressures (232 bar / 300 bar).
  

Available Variants and Sizes:

Select the exact model based on the cartridge or filter body installed on your compressor from the dropdown menu:

• Version for MAXIFILTER (6 Pieces - Diameter 4 cm): The kit contains 6 specific felt discs with a diameter of 40 mm, designed to integrate perfectly into Maxifilter line purification systems.
• Version for HYPERFILTER (8 Pieces - Diameter 6 cm): The kit includes 8 enlarged felt discs with a diameter of 60 mm, developed for the high-capacity filter bodies of the professional Hyperfilter line.

Main Fields of Use:

• Routine Compressor Maintenance: Primary component that must be replaced at every regeneration or replacement of the main filter cartridge.
• Air Quality Protection: Essential for dive centers, refill stations, and technical divers who demand air or mixtures (Nitrox/Trimix) completely free of oily contaminants.

Target Users:

This Coltri felt kit is an indispensable consumable item for owners of personal compressors, diving centers, and maintenance technicians who rigorously care for the purity of breathing air. Choosing the correct size and the relevant set of spare parts ensures perfect sealing of the flow within the filtering system.
