Product Overview

The hermetic filter drier, OEM number 023Z0264, is a Danfoss DML 305FS-type component used in the air conditioning systems of buses, trucks, and other commercial vehicles. It's a standard component across many bus and coach A/C installations that use Danfoss-spec refrigeration hardware, making it a useful item for distributors serving commercial vehicle A/C parts demand.

Worn or failing filter driers typically show up as reduced cooling performance, moisture or contamination in the refrigerant system, or visible frost or icing on system lines. GSK Auto manufactures this filter drier to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

What Is a Filter Drier?

Function: The filter drier removes moisture and contaminants from the refrigerant circulating through an air conditioning system, protecting the compressor and other components from damage.

Working Principle: Refrigerant passes through a desiccant material inside the drier housing, which absorbs moisture and traps particulate contaminants, keeping the refrigerant clean and dry as it circulates through the system.

Importance: On a bus or truck A/C system, a properly functioning filter drier is essential for reliable cooling performance and protecting the compressor from moisture-related damage.

Common Failures & Signs: Reduced cooling performance from a saturated or clogged drier. Moisture contamination in the refrigerant system. Frost or icing visible on system lines. Compressor noise or damage from unfiltered contaminants.
