Filters Vital to Compressed Air Systems
Filters are a vital component of air treatment in any compressed air system. Today’s air compressor system must be efficient, cost-effective and most importantly, it must deliver air to a specific standard of quality.

Pre-Cleaning
An important first step to high quality air is pre-cleaning the air prior to entering the air compressor. If contaminants are permitted to enter the compressed air system, they will corrode and damage the system. Pre-cleaning reduces the need for “downstream” treatment devices. It is an important part of the overall process to achieve high quality air.

Moisture Removal
The second point of air treatment takes place within the air compressor itself. An air compressor’s cooling fluid tends to wash contaminants out of the air as it is compressed. Plus, up to 90 percent of the moisture content of the inlet air is removed by aftercoolers on the compressor.

High Quality Air
The third level of air treatment generally involves use of dryers. Because the majority of compressed air applications require moisture removal down to a pressure dewpoint of about three degrees, a standard refrigeration dryer is sufficient. For higher classes of air quality, dryers may not be sufficient and that’s why a comprehensive range of filters is offered to meet any quality requirement even as demanding as 0.001 ppm remaining particle and oil content. With sophisticated filters, monitoring systems, drains and adsorbers to remove hydrocarbons, Hope Air Systems has the components and technology needed for your compressed air filtration requirements.

Filters Combat Contaminants
On average, ambient air contains about 190 million particles of dirt, hydrocarbons, viruses and bacteria per cubic foot. The majority of these contaminants enters the compressor and may still be present in the resulting compressed air. If the air is not properly treated, these contaminants can damage pneumatic machinery and air tools, or even wind up in the end product. To combat these contaminants, air compressor filters are available including:

filtered separators
particulate filters
oil removal filters
extra fine oil removal filters
vapor adsorbers

Hope Air Systems Recommends Kaeser Filters
Hope Air Systems frequently recommends Kaeser filters and filter elements for its customers. Some of the important features and advantages of the Kaeser filters are:

multi-layer, matrix-blended fiber media
efficient operation under low use conditions
filter element seals to housing
durable, anti-corrosive housing
epoxy powder coating inside and out
element supported by stainless steel orifice tubes
internal and external drain traps available
differential pressure slide indicator available
analog differential pressure gauge available
microprocessor-controlled filter monitor option

Compressed Air Filters
Filters from Kaeser were designed and developed using the latest innovations and manufacturing techniques. The filter housings are designed with larger flow areas to ensure low pressure drop and to provide easier installation, operation and maintenance. The result is consistent product quality while minimizing operating costs.

Replacement Filter Elements
Hope Air Systems recommends Kaeser filter replacement elements, which are available in a wide range of types and sizes to meet the OEM and ISO requirements of its customers.

Oil Mist Eliminator
To go beyond what an air line filter could accomplish, Hope Air Systems often recommends the Kaeser Oil Mist Eliminator as an economical way to protect equipment, material and products from contamination with extremely low pressure drop.

Activated Carbon Filter
To help eliminated hydrocarbon vapors from compressed air systems, Hope Air Systems recommends Kaeser’s Activated Carbon Tower adsorber system.

High Temperature Afterfilter
To help the efficiency of desiccant dryers, Kaeser offers a High Temperature Afterfilter designed for temperatures up to 450 degrees Fahrenheit. They are commonly placed after heated desiccant dryers to combat dust buildup and prolong cartridge life.

Filter Monitor
The Kaeser Filter Monitor is a microprocessor control with LCD display to indicate optimum element replacement based on operating time, differential pressure and filter type
