FOR IMMEDIATE RELEASE
SPIRACLE ™ -- A NEW DONALDSON CLOSED CRANKCASE FILTRATION TECHNOLOGY BOOSTS DIESEL ENGINE PERFORMANCE, EFFICIENCY
AND ENVIRONMENTAL FRIENDLINESS
MINNEAPOLIS, March 20 — A new high-performance closed crankcase filtration system from Donaldson Company Inc. eliminates engine crankcase emissions and improves the operating efficiency of diesel engines in medium- and heavy-duty trucks and buses, light vehicles such as pick-up trucks, medium and heavy-duty off-road equipment, and light industrial equipment.
The Donaldson Spiracle™ Filtration System uses an innovative two-stage coalescing process to efficiently remove entrained oil mist while maintaining crankcase pressures. Mounted between the engine breather port and air intake system, the Spiracle system helps reduce unpleasant in-cab fumes and keeps engine enclosures free from oil film deposits by efficiently filtering and routing blow-by gases back to the air intake. The filtration system also helps lower replacement oil costs by returning coalesced oil to the engine sump.
“Precision components critical to the efficient diesel engine operation demand superior filtration,” said Marty Barris, director of air filtration applications and development, Donaldson Company. “The Spiracle system effectively eliminates blow-by particulate matter emissions to meet new on- and off-road environmental regulations, while reducing operating costs, protecting against engine power loss, and with extended service life.”
The heart of the Spiracle system is a high-efficiency coalescing filter produced by a proprietary process of arranging filter media fibers into a first stage impaction filter. Partially-cleaned gases and coalesced oil flow along a coalescing tube on the inside of the cartridge, allowing oil removal at the bottom of the housing. The blow-by gases are then forced through the second stage diffusion filter/coalescing media from the inside of the cartridge where additional coalescing is performed using a proprietary oliophobic filter media. Separated oil is returned to the engine sump, while soot particles remain trapped on the media surface.
Constructed to withstand engine temperatures, vibration, and chemical exposure, the Spiracle product line includes three sizes to handle blow-by flows ranging from 50 to 690 lpm (liters per minute). The filters are capable of engine- or remote-mount for wide application flexibility. A top-loaded metal-free cartridge design makes Spiracle ideal for serviceability and environmental friendliness concerns.
Donaldson is shipping Spiracle-technology filtration systems to Scania for use in Scania DC16 diesel engines. The new DC16 is a 16-litre, V8 turbocharged diesel engine with air-to-air charge cooling and individual cylinder heads for higher ratings and easy servicing. Scania is one of the world’s leading manufacturers of trucks and buses for heavy transport applications.
