Atlas Copco Screw Compressor Line Filter Cartridge by Halward

We sell a full line of replacement air compressor filter elements. From the major brands to the hard to find, including filters typically found on the air line, like coalescing filters (pre-filters) and particulate filters (after-filters), and filters that are on the compressor itself, like oil filters, air intake filters, and air/oil separators for rotary screw compressors.

COALESCING FILTER (PRE-FILTER) ELEMENTS

Coalescing filters capture oil, moisture and particles, binding them together until their mass is heavy enough for gravity to send this waste to a drain valve. A coalescer filter is often called a pre-filter because it is usually located prior to an air dryer to prevent oil and particulate from soiling the desiccant.

PARTICULATE FILTER (AFTER-FILTER) ELEMENTS

A particulate filter, also known as an after-filter, is usually located just after the desiccant air dryer to capture any fine desiccant particles that may be in the line. If the particulate filter gets soiled more frequently than what is typical for your environment, it may be time to replace the desiccant.

ADSORBER FILTER ELEMENTS

Adsorbers remove odor from process air and are usually located on the air line after the dryer. Adsorption filters with activated carbon are for adsorption of harmful gases and smells from the air. The largest use of Carbon elements is in the purification of water. Activated carbon achieves the maximum enlargement of inner and outer surface after the special treatment and so the adsorption area is extremely high - up to 1250 m2 for every gram of active carbon.
