EPG

This EPG RadialSeal™ air cleaner is able to fit in tight spaces under the hood, is corrosion-free and is lighter in weight than traditional metal units.
This EPG RadialSeal™ Air Cleaner is part of a complete Donaldson intake system. The entire engine air intake system is made of molded plastic. Between the intake scoop and the air cleaner are Donaldson Strata™ tubes, which provide pre-cleaning. Particulate from this stage is scavenged off and out through the exhaust system. In this system, the EPG air cleaner provides the second stage of cleaning.

Applications

  • On-highway vehicles
  • Marine and offshore equipment
  • Light construction vehicles
  • Agricultural vehicles
  • Compressors and generator sets
  • Temperature tolerances: 
    • 279 mm / 11 in. diameter: -40° C to 104° C / -40° F to 220° F 
    • 330 mm / 13 in. diameter: -40° C to 93° C / -40° F to 200° F
    • 381 mm / 15 in. diameter: -40° C to 93° C / -40° F to 200° F


Benefits

  • Easy to service
  • Easy to integrate
  • Sure sealing system
  • Donaldson Blue™ high efficiency, extended service filter option available
The EPG Air Cleaner, which fits neatly under the hood, has RadialSeal™ Sealing Technology that delivers a reliable seal in rugged environments and quick filter change-out.

Features

  • Provides up to 37.5 m³/min / 1325 cfm airflow per air cleaner — double airflow to engine by using two units
  • Horizontal or vertical installation
  • Durable plastic housing is corrosion-free and weighs less than metal air cleaners
  • Very few service parts. Easy to service
  • No mounting bands required. Installs securely via molded-in mounting flange(s) with pre-drilled holes on the side of the housing
  • Available in three body diameters: 
    • 279 mm / 11 in.
    • 330 mm / 13 in.
    • 381 mm / 15 in.
  • RadialSeal™ Sealing Technology ensures reliability, is easy to service and makes the filter self-centering, self-aligning and self-sealing
  • All models can accommodate safety filter
  • Donaldson Blue™ high efficiency, extended service filters are available for some models. Donaldson Blue filters capture sub-micron contaminant, such as soot and carbon, which promotes lower restriction and longer filter life

1. Check the Restriction
Measure the restriction of the air cleaner with a Donaldson filter service indicator, service gauge or water manometer. Use the restriction tap provided on the air cleaner or at the transfer pipe. Replace the filter only when the restriction level has reached the maximum recommended by the engine or equipment manufacturer or on a regular service schedule

2. Remove the Filter 
Unfasten or unlatch the service cover. The RadialSeal™ filter fits tightly over the outlet tube to create the critical seal, so there will be some initial resistance, similar to breaking the seal on a jar. Gently move the end of the filter back and forth to break the seal. Rotate while pulling the filter straight out. Avoid knocking the filter against the housing. 

3. Clean Out the Vacuator™ Valve 
Remove the Vacuator Valve and clean out any dust found in the drop tube. Reinstall Vacuator Valve or replace if found worn or damaged. If your air cleaner is equipped with a Vacuator Valve, visually check and physically squeeze it. 

4. Inspect the Old Filter
Inspect the old filter for any signs of leaks. A streak of dust on the clean side of the filter is a telltale sign. Eliminate any source of air leaks before installing the new primary filter.


5. Visually Inspect the Safety Filter 

If your air cleaner has a safety filter, do a visual inspection for damage. Verify that the safety filter is properly seated in the housing. Do not remove the safety filter unless it is damaged or due for replacement. The safety filter should be replaced every three primary filter changes. When you remove the safety filter, replace it immediately or make sure you cover the air cleaner outlet tube to avoid admitting any contaminant.


 

6. Clean Both Surfaces of the Outlet Tube 
Use a clean damp cloth to wipe the filter sealing surface and the inside of the outlet tube. Contaminant on the sealing surface could hinder an effective seal and cause leakage. 

7. Inspect the New Filter 
Visually inspect the new filter, paying special attention to the sealing area which is inside the open end.

As you inspect the filter’s RadialSeal take care not to wipe the sealing surface. The factory has placed a dry lubricant on the seal which aids in installation and removal. NEVER install a damaged filter.

8. Insert the New Filter Properly 
If you’re servicing the safety filter at this change-out, carefully seat it into position before installing the primary filter. Seat the filter by hand, making certain it is completely inserted into the air cleaner housing before securing the cover in place. To complete a tight seal, apply pressure by hand at the outer rim of the filter, not the flexible center.

Never use the service cover to push the filter into place since no cover pressure is required to hold the seal. Using the cover to apply pressure could damage the housing and cover fasteners, and will void the warranty.

If the new filter is not fully in place, remove the cover and push the filter further into the air cleaner with hand pressure on the outer rim. The cover should then go on with no extra force. Then secure the service cover.
 

9. Check Connectors for a Tight Fit
Make sure restriction indicators are reset and in proper working order. Verify that all mounting bands, clamps, bolts, and connections in the entire air cleaner system are tight. Check for holes in piping and repair or replace as needed. Any leaks in the intake piping will admit dust directly to the engine.
