Clean dry air is crucial to the performance of any compressed air system along with the downstream components. Line filters remove impurities such as solid particles, dust, dirt, rust, scale, oil, and condensate.

Activated Carbon is especially useful in Lab, Medical, and Food applications.

2-in-1 Cartridge features both Activated Carbon & integrated 1 Micron Filter.

KSI's ECOCLEAN Advanced Premium Filtration (APF) line is manufactured in accordance with DIN EN ISO 9001 quality assurance standards, and is 100% leak tested. ECOCLEAN filters also exceed ISO 8753-1:2010 standards for compressed air purity, carry Canadian Registration Numbers (CRN) for North America, and approval for fluid group 2 in accordance with Pressure Equipment Directive 2014/68/EU, module B+D (category IV).

ECOCLEAN Filters are available in 25 micron, 1 micron, 0.01 micron, as well as Water Separators, Molecular Sieve, and Activated Carbon.

A 10psi pressure drop represents a 5% increase in energy cost
Over the 10 year life of a compressed air system, on average the cost of energy to run the system far outweighs the capital investment of buying it. Maintenance costs may not be much, but it is extremely important because it directly impacts energy efficiency and system health. Neglected filters create a constant pressure drop, which destroys the energy efficiency of your system while entrained oil, water, and particulate destroys system components. Protect your equipment, tools, processes, and ultimately your business with proper air treatment and regular maintenance!

For every compressed air system, we highly recommend installing Air Dryer, Water Separator, 1 micron Line Filter, and 0.01 micron Line Filter for the highest quality air.
