XLR Powered Precleaner for Engines

NEW! XLR Powered Precleaner for Engines: 99.99% Efficient on ISO Fine Test Dust!

XLR = eXtra Low Restriction

Tired of dusting your engines due to poor filter maintenance practices?

Are on the job air filter changes contaminating your oil samples?

Sy-Klone« International now offers the XLR™ Powered Precleaner™ for maximum precleaning in impossible environments with the lowest possible restriction to protect your engine! This high efficiency powered precleaner removes 99.99% of ISO fine test dust. With the addition of power, there is zero restriction up to 130 CFM (3.68 m3/min).

  • High efficiency powered precleaner removes more than 90+% of the dust BEFORE it reaches the prefilter.
  • High efficiency radial seal prefilter then removes 99.99% of ISO fine test dust.
  • Patented self-cleaning prefilter drops dirt continuously, which is then ejected from the XLR filter housing.

The XLR Powered Precleaner offers two sizes to maximize your precleaning ability. The unique design allows for an easy air filter change with no engine contamination.

Real World Performance:

Antwerp, Belgium

Wheel loader

Extremely dusty environment in a cement factory

Indefinite engine filter life and an estimated $47,153 savings per year*!

Before XLR installation:
Restriction light for engine filter came on after 4 hours of run time. The engine and 2 catalytic converters were dusted (had to be replaced) in the first 5000 hours of run time at a cost to the machine owner of $39,500.

Downtime cost for filter changes and lost production time is estimated to be $73,375 annually

After Dual XLR installation:
The prefilters were still operational after 260 hours of running in impossible dust conditions! Primary engine filter remained like new.

Annual calculated savings for the customer: $47,153 per year.

XLR Powered Precleaner performs in impossible environments like this cement factory!
