Advantages of Breather Filter

Improved Engine Performance
The clean air provided by breather filters ensures engines receive the optimal mix of air and fuel, resulting in improved combustion and overall performance. When dirty or contaminated air enters the engine, it can clog internal components, reduce power output, and shorten the engine’s lifespan.

 

Enhanced Filtration for Hydraulic Systems
Hydraulic systems are particularly sensitive to airborne contaminants. Dust or moisture in the hydraulic fluid can damage pumps, valves, and other components. Air breather filters for hydraulic tanks prevent this by delivering filtered air, which complements existing internal filters and reduces ingression of contaminants.

Environmental Benefits

By keeping harmful particles out of the system, air breather filters indirectly prevent pollutants from being released into the environment. Additionally, their role in maintaining system performance often leads to lower emissions and better fuel or energy efficiency.

Cost Savings

Dirty systems break down faster and need frequent repairs, leading to high maintenance costs. Air breather filters, on the other hand, offer a cost-effective solution by extending the operational life of machinery. Fewer repairs, reduced downtime, and improved system efficiency equal significant savings in the long run.

Protection Against Moisture and Humidity

Some breather filters, such as those used in hydraulic systems, are designed to eliminate moisture and humidity. This is particularly important in industries like agriculture, construction, and mining, where systems are exposed to varying weather conditions.

Applications of Breather Filter

Hydraulic Systems
Used in hydraulic reservoirs to prevent dirt ingress, which can cause wear and failure. For example, in construction machinery, clean hydraulic fluid ensures smooth operation and reduces downtime.

 

Gearboxes and Transmissions
Protects gear components from dust and moisture, extending service life. Automotive manufacturers rely on breather filters to maintain transmission health.

 

Compressors
Ensures that intake air remains free from particulates, which can damage compressor blades and reduce efficiency. Industrial plants use them to maintain compressor longevity.

 

Energy Sector
In wind turbines and solar power systems, breather filters help keep internal components free from environmental contaminants.

 

Agriculture
Equipment like tractors and harvesters benefit from breather filters to operate reliably in dusty fields.

 

Steps for Replacing the Breather Filter
 

Steps 1: Find Your Filter
Locating the air filter housing is simple if you have your owner’s service manual handy. Once you have located it, loosen the fasteners holding the housing cover together. The type of fastener will vary from make and model and year-to-year. They can be wing nuts or clips or some other form of fastener.

 

Step 2: Remove Old Air Filter
Now that you have loosened the fasteners, you can remove your filter. You should look and see how the filter is place in the housing and how it fits. Once you have made these observations, you should be able to pull it out easily.

 

Step 3: Clean Housing
Now that you have space to work with, clean the inside of the breather filter housing. You can use a damp rag, sponge, or towels. Don’t use anything too wet, though, and try not to let anything get into the air duct. Some, but not all, cars have a crankcase breather element.

 

Step 4: Find Breather Filter
Just as you did with the air filter, use the owner’s manual to find your crankcase breather filter. If it is encased in a housing, remove the clips to access the filter. You need to determine if the filter is the only thing needing replacement or if the inner holder goes as well.

 

Step 5: Install New Filter
Installation is simple. Attach the new breather filter with retaining clips. Just make sure the placement is correct. Put the filter back into its housing, then reattach the cover on the filter hosing. Make sure everything is securely in place before operating your car.

 

Breather Filter Maintenance

 

Regular Inspections

Periodically check your air breather filter for visible damage, tears, or clogging. Replace filters showing wear immediately.

01

Cleaning and Replacement

Some filters can be cleaned and reused, while others are disposable and need replacement. Always follow manufacturer recommendations to determine the correct cleaning or replacement schedule.

02

Measure Filtration Effectiveness

Use a differential pressure gauge to monitor the breather’s performance. A rise in pressure may indicate blockages or inefficiencies.

03

Change Elements Regularly

Filter elements have a finite lifespan. Replace them periodically to maintain filtration effectiveness and system efficiency.

04

Consider Usage Conditions

If your system operates in particularly harsh conditions (such as extreme dust or humidity), you may need to clean or replace filters more often.

FAQ

 

Q: What is the point of a breather filter?

A: A breather filter allows clean air into an engine's crankcase or a hydraulic system's reservoir while simultaneously preventing contaminants like oil, dirt, and moisture from entering. In engines, it connects to the Positive Crankcase Ventilation (PCV) system to help relieve pressure and remove harmful blow-by gases from the crankcase, protecting the oil and preventing leaks. In hydraulic systems, it prevents debris from damaging components and captures expelled oil mist.

Q: How do I choose the right breather filter?

A: When choosing a breather model, always select a model with a CFM rating greater than the CFM requirements of the tank or reservoir. Installing a breather with inadequate airflow will create excessive pressure or vacuum and will cause damage to the equipment.

Q: Can I clean and reuse a breather filter?

A: While many people may not realize it, cars often have reusable air filters, which provide significant benefits over disposable ones. Reusable air filters are more environmentally friendly, as they can be cleaned and reused multiple times, reducing waste.

Q: How often should a breather filter be replaced?

A: Crankcase breather filters should typically be replaced every 500 to 1000 operating hours, depending on conditions. A clogged breather causes pressure buildup, leading to oil leaks and engine seal damage. Inspect the filter visually for dirt or oil saturation during routine maintenance.

Q: What is the difference between a breather filter and an air filter?

A: An air filter cleans the air entering the combustion chamber of an engine to ensure efficient fuel combustion. A breather filter, on the other hand, cleans the air and controls pressure in sealed systems, such as the engine's crankcase or hydraulic fluid reservoir. They perform different functions and are both necessary for the health of heavy machinery.

Q: Can you clean a breather filter instead of replacing it?

A: Some breather filters, particularly those designed for high-performance applications, are washable and reusable. Others are designed to be disposable. It is important to follow the manufacturer's instructions to know whether cleaning is an option and what cleaning solution to use.
