Title: Installing a pre cleaner
Post by: oldguy on April 23, 2021, 11:19:53 pm
I'm falling Scotts advice and installing a pre cleaner with his help. When I took out the new air cleaner there already had water on
it and dust in the filter so I'm sure this is a good idea.

WOW, was your coach under water at some time? I can't believe all the rust!

In-Line Separators

Donaldson in-line separators provide two-stage cleaning for unexpectedly heavy dust/moisture conditions.

When your truck is being used in heavier-than-anticipated dust or moisture conditions, you may not have to replace the entire air cleaner. The problem may be solved by adding a Donaldson in-line separator. This enables an over-highway vehicle, which usually sees only light dust, to be easily and economically adapted to off-road medium to heavy dust conditions.

Features

Economical way to convert air intake system from light dust to medium to heavy dust condition
80% water removal efficiency
70% dust removal efficiency
Applications

Vertical model: On/off road, mounted on inlet tubing or cowl mounted directly to air cleaner – Compatible with engine airflows of 14.2 to 42.5 m³/min / 500 to 1500 cfm

Ordered H000878 today for my coach. Finally a fun project. Have been involved in the installation of these on two other coaches used in dusty conditions. No moving parts but exceptional operation. Dirty side of filter housing stays clean. Filters will be changed for time not dirty condition. They work really well. First learned of them on my Offroad car. Adds a additional vacuator valve that will have to be changed when air filter housing vacuator is replaced.  More to follow once parts get here.

I'm still amazed how well it works. 100% glad I installed.

Went to the Metal Supermarket and bought a piece of 18 gage 5 inch by 24 inches metal and then made a extension for the air
cleaner housing. When it quits raining I will tac the piece onto the housing to make sure everything will fit.

I added 5 inches and angled the extension as Scott suggested and finished up installing it today.

I have done this mod to mine and it has proven its worth at King Of Hammers, .  ^.^d  Dust was expelled out the vacuvalve. Very effective. Jim.
