SKF 3-in-1 dryer improves performance of compressed air

Nov. 30, 2009 - PRLog -- SKF, the leading knowledge engineering company, has developed an innovative 3-in-1 dryer system that removes oil, contaminants and water from compressed air. The compact SFD (Separator Filter Dryer) system can treat a compressed air stream directly from the tank, eliminating the need for after coolers, additional external filters and other equipment, or alternatively be mounted on small air compressors or at the point of use. The SFD provides a reliable and versatile drying solution, able to accommodate a range of air system requirements and flow rates.

The SKF Separator Filter Dryer is capable of providing uninterrupted operation, even in dirty or dusty conditions, minimising maintenance and downtime. The unit can withstand high or low ambient temperatures, making it suitable for use in a wide range of industrial applications, including concrete plants, warehouse operations, automotive paint booths, and other manufacturing facilities.

The SFD is simple to install, simply plugging into a standard 12, 24 or 120V AC, while a fully pneumatic version is also available, which requires no electricity at all. No condensate drain line is needed with either model, and there is no heat exchanger to clean or maintain. The compact design of the system allows it to be discretely installed directly on the tank, the compressor top plate, or on the wall.

The standard SFD unit removes water from compressed air streams of pressures up to 180 psi. An optional internal filtration/oil separator system also removes oil and filters out contaminants as small as 0.1 micron, improving the performance of pneumatic applications, and extending maintenance intervals and service life. The SFD unit can be specified with or without the internal filtration option for 5, 7.5, 10, 15 or 20 horsepower applications.

The system is extremely energy efficient and typically averages 5-6% of air for regeneration. As the SFD does not require a refrigerant, the environmental impact of applications can be reduced still further.
