Overview

Maintaining a clean compressor ecosystem is crucial for optimal performance, energy efficiency, and longevity. Donaldson offers filtration solutions, including lube filters, air-inlet filters, and air-oil separators, designed to help keep your compressors running smoothly and efficiently. Our end-to-end technology helps provide peak performance to help keep your operating costs low.

Lube Filters for Compressors

Clean oil is essential to maintaining ideal compressor performance and reducing downtime, but every speck of dust entering a compressor will mix with the oil. The purpose of a lube filter is to capture dirt and contaminants in the oil/lubricant.

Donaldson PurFlo™ lube compressor filters have unique features and benefits that help compressor lube systems operate at peak performance:

  • Rugged design proven to mechanically perform beyond standard service
  • Filtration efficiency of 99% @ 37µm or ß37 = 100 per ISO 16889
  • Dependable performance with long service life
  • Seals compatible with commonly used compressor fluids
  • Compatible with most existing designs

Our oil filters for air compressors are designed to help extend oil life, reduce wear, and improve efficiency, which in turn could help prevent costly downtime. Donaldson offers over 35 different grades of filtration media to tailor our lube filter designs to your specific compressor application. These can be custom-engineered to filter specific contaminants and meet element-life requirements.

Donaldson lube filters use proven, long-lasting components to deliver the desired filtration with minimal pressure drop. From the heavy-duty can to the louvered center tube with spiral-lock seam design, Donaldson filters are designed to fit your application, maintain their seals, and outlast generic products.

Our global manufacturing and distribution teams help you find the filters you need, when you need them.


Air-Inlet Filters for Compressors

Clean air out begins with clean air in. The inlet air filter prevents dirt and dust particles from entering the compressor. This helps minimize wear and tear on the air end (airend), extends air oil separator and lube filter life, and provides clean compressed air to the plant or your mobile power tools and applications.

Donaldson’s innovative engine air cleaning system, filter media, and custom inlet air filter designs continue to lead the industry. Air compressors come in all shapes and sizes, and we’ve built thousands of housings for a wide variety of systems. From pleated media designs to our unique PowerCore® fluted media configuration, we’re continually developing new ways to filter more air in less space to help keep your customer’s operating costs low. A Donaldson inlet air filter can be customized for most flow ranges and environments.

Donaldson air inlet filters for compressors are designed to prevent dust, dirt, and other airborne particles from entering your compressor. Our advanced air intake filters improve air quality, reduce internal contamination and extend component life. Donaldson’s compressor dust filters can be used to support your efforts to be energy efficient and low maintenance.
 

Air Oil Separators for Compressors

Before the compressed air is released to the system, it passes through an air oil separator to remove any remaining oil mist. Donaldson air-oil separators employ our unique coalescing media technology, developed to efficiently remove oil mist from the air with the lowest possible added restriction.

As the last step before air leaves the compressor, the air-oil separator is often the first consideration in an optimized compressor ecosystem. Donaldson uses state-of-the-art materials in its air-oil separators, combined with proprietary media types that offer lower pressure drop and longer life than traditional media while performing at the highest level.

Donaldson’s innovative air oil separators for compressors efficiently separate oil from the compressed air stream, helping reduce oil carryover to support your air quality needs and keep operating costs low.
