XLR Powered Precleaner: Frequently Asked Questions

What's the air flow range?
Covers engine air flows up to 350 CFM (9.91 m3/min) and much higher with multiple unit installations
What is the operating airflow range?
0- 350 CFM (9.91 m3/min)
How will I know when I need multiple XLRs?
Each unit covers an engine airflow up to 350cfm. Anything higher than 350 cfm will require additional units.
What are the voltage options?
Available in 12 and 24 volts
How much restriction is added?
There is zero restriction up to 130cfm.
Is there an operating temperature range?
-40° F to +176° F (-40° C to +80° C) continuous; +185° F (+85° C) short exposure
Does XLR replace my engine filter?
No, the XLR is an engine prefilter that offers precleaning prior to the primary filter (outer filter).
Is my safety filter necessary?
Customer Preference. With the XLR's high efficiency filter and radial seal, debris should not pass the prefilter and the primary filter becomes the safety filter.
>After installing XLR, my original primary filter is getting dirty. Why?

Can my XLR be mounted vertically or horizontally?
The XLR can be mounted horizontally or vertically (with rain cap end up). Optional Flange Mount (RIC0701) available for through-the-wall installations.
Are all of the installation parts included?
No. Installation varies from machine to machine. Sy-Klone offers various kits to support installation on a variety of machines. Sy-Klone also offers drawings for multiple installation adaptation for your use.
Is there a specific kit for my vehicle?
Sometimes. Call Sy-Klone for more information. We also offer generic installation kits.
How does the XLR Powered Precleaner compare to other precleaning technologies?
XLR maximizes precleaner efficiency across the entire engine airflow range, as well as incorporates a high efficiency prefilter. It is a fantastic solution for extreme environments.
Does installing an XLR void my warranty?
No. XLR is a precleaner. The original machine configuration remains the same.
How much more efficient are the XLR prefilters compared to typical engine filters?
Much more efficient! Typical engine air filters arrest particulate down to 10 microns. XLR high efficiency filters arrest particulate down to 0.3 micron.

How is XLR able to provide such low restriction precleaning?
Instead of using the power of the engine to draw air through the precleaner, the precleaner uses its own motor and fan to push air through the precleaner, thus reducing restriction.
How far away from the engine air intake can I install an XLR?
The farther away, the more restriction.
Why is my XLR not working?
- Check connectors
- Check power to XLR and relay
My vehicle restriction (change filter) indicator issued a warning. What do I do?
- Check XLR prefilters for debris.
- If dirty, change.
- If not dirty, check for XLR operation
- At air cleaner outlet tap point, verify restriction reading with handheld manometer. Compare to Vehicle reading.
Can I blow out my XLR filters?
No. Blowing out filters can damage the high efficiency filter media.
Does engine series (Tier 3, Tier 4, etc.) affect my ability to use XLR?
No. XLR can be used on all engines.
What inlet options are available?
Rain cap is standard. Heavy debris screen (RIC0918) is recommended for Landfill and other heavy-duty applications.
