Hermetically sealed mechanical filter-drier with high hygroscopic capacity for the liquid line, equipped with a solid desiccant block consisting of 100% molecular sieves (3Å) and 3/8″ connections. Featuring a high-volume carbon steel housing (outer diameter 73 mm, total length 174 mm), it is designed to ensure thorough dehumidification and effective mechanical filtration in commercial refrigeration, air conditioning, and heat pump systems operating with HFCs, HFOs, and synthetic oils (POE and PAG).

Description
Greater Filtration Volume and Total Protection for Medium-Power Systems
Thanks to the cartridge’s larger dimensions (Ø 73 mm x 174 mm), this filter-drier offers a significantly larger filtration surface area and molecular sieve volume compared to standard compact models. The 100% sintered molecular sieve cartridge (3Å) retains water dissolved in the circuit before it can react with the synthetic oil and trigger the formation of corrosive acids, protecting the check valve from freezing and the compressor from electrical or mechanical failures.
The solid extruded structure prevents flaking and the release of desiccant dust into the flow, while the generously sized welded steel body ensures low pressure drop even at high refrigerant flow rates.
Strengths & Advantages:
High Water Retention Capacity: The cartridge’s increased volume allows it to adsorb large amounts of residual moisture, making it ideal for new systems or post-maintenance systems with extended lines.
100% Solid Core with Molecular Sieves (3Å): Chemical selectivity specifically designed to absorb water, without removing refrigerant or altering the additive package of synthetic oils.
Low Pressure Drop: The large flow cross-section (Ø 73 mm) optimizes liquid refrigerant circulation, reducing pressure drops in the line before the expansion valve.
Mechanical Filtration Down to 20 Microns: Internal filter media located upstream and downstream of the compact block to trap sludge, metal slag, and brazing residues.
Steel Housing with Epoxy Coating: A deep-drawn body resistant to high pressures and electrostatically painted to protect against atmospheric corrosion and condensation-induced rust.
