Air Filter Types

The reliability of compressed air filtration is paramount to the ongoing fight against problems caused through contamination entering the air system. Contamination in the form of dirt, oil and water can lead to:

Pipe scale and corrosion within pressure vessels
Damage to production equipment, air motors, air tools, valves and cylinders
Premature and unplanned desiccant replacement for adsorption dryers
Spoiled product

The CompAir filtration range offers various products and grades of filtration to provide peace of mind whatever the air quality requirement. To meet the various requirements, CompAir filters are available in three different grades:

Type B: General Purpose Protection. It provides particle removal down to 1 micron, including water and oil aerosols.
Type C: High Efficiency Oil Removal Filtration & High Efficiency Dust Filtration. Particle removal is down to 0.01 micron, including water and oil aerosols.
Type D: Oil vapor and hydrocarbon odor removal, providing a maximum remaining oil content of <0.003 mg/m
Type E - General Purpose Dust Filtration, dust particle removal down to 1 micro

Innovative features mean outstanding performance without compromise. With differential pressure that starts low and stays low, these filters offer a solution to applications that demand high performance filtration without the usual high energy running costs. The CompAir filter range provides clean, high-quality air as defined by ISO 8573.1:2010 and are certified by a third party under ISO 12500-1.

Water Separators

X-Series of water separators

The X-Series of water separators provide bulk condensed water and liquid oil removal and are used to protect coalescing filters against bulk liquid contamination. Bulk liquids such as condensate, water and liquid oil are removed from the airflow through directional and centrifugal separation. Installed before a coalescing filter, the water separator can provide added protection against bulk liquid contamination enabling the filter to operate more efficiently. The X water separator range from CompAir can operate across various flow conditions and have been optimised to reduce differential pressure with very low maintenance.

CF-Series filters

The CF-Series of filters efficiently removes water and oil aerosols, atmospheric dirt and solid particles, rust, pipescale and micro-organisms.

CFT Modular Filters

When compressed air is required to meet ISO8573-1 Class 1 air quality via oil free or oil lubricated compressors, the CFT Oil Vapour Removal filter is an essential component of the compressed air system. They are designed to reduce oil vapour. Compact activated carbon cartridges utilise a unique filling technique to maximise packing density of the adsorbent bed. The use of cartridges also provides trouble free maintenance, reducing system downtime.
