marine air filters

NorthWest Clean Air Company (NWCA) provides high-performance permanent air filters for diesel engine turbochargers, main air handling units, and in passenger cabin and public area fan coil units used in ship operations.

Our permanent / washable electromechanical air filters are at the forefront of the industry, and have been designed to offer maximum performance in demanding marine environments.

Through the use of NWCA next-generation washable air filters, ship owners are saving tens of thousands of dollars per vessel every year and eliminating thousands of disposable air filters from landfill sites.

NWCA filters fit ABB, MAN, and others.
Each turbocharger filter element is fabricated with double stitched edge bindings.
The NWCA next-generation AHU filter incorporates the principles of both electrostatic and mechanical filtration.
NWCA next-generation filter frames are fabricated using AISI 316L stainless steel.
NWCA PAX cabin filters can easily be installed in passenger cabin and public area fan coil units.
NWCA filters eliminate the need to continuously dispose of air filter material.

Turbocharger air filters with a ten year warranty

The NWCA electromechanical turbocharger filters are custom-fabricated to fit the silencer dimensions of leading marine turbocharger manufacturers, such as ABB, MAN, and Mitsubishi.

Each filter element is fabricated with double stitched edge bindings, and is complete with an adjustable Velcro attachment for ease of installation and a secure fit. The flexibility of our upholstery division allows for virtually any size required by the vessel.

Our permanent / washable turbocharger filters offer low-resistance, and provide complete silencer air intake coverage, eliminating blowby. The filters are designed to protect the charge air cooler, and reduce compressor contamination. Cleaning maintenance is achieved by washing with a degreaser.

NWCA turbocharger filters eliminate on-board synthetic roll media inventories, cutting time and disposal costs of the waste filter material.

Air handling unit air filters with a twelve year warranty

The NWCA next-generation electromechanical AHU filters eliminate the need for and the ongoing expense of disposable air filter material, providing significant cost savings and eliminating landfill waste requirements.

Designed specifically for use in high-velocity ship air handling units, the NWCA permanent / washable marine air filter is fabricated using AISI 316L stainless steel, with the 23mm frame welded and polished, complete with two drainage holes per leg. The filter media incorporates the principles of both electrostatic and mechanical filtration.

Direct results include:

  • Remove costly shipboard filter inventories (disposable filter media)
  • Minimise storage space for spare sets
  • Eradicate the costs of replacement cooling coils at dry dock intervals due to fin blockage caused by wet or torn air filter media debris (disposable bag filters)
  • Eliminate the negative environmental impact of disposable filters to landfill sites
  • Easily cleaned by washing with high or low pressure water

Passenger cabin filters and public area fan coil unit filters with a twelve year warranty

These next-generation electromechanical permanent / washable air filters are also fabricated using the same AISI 316L stainless steel components and filtration criteria as our air main handling unit filters with the exception of the sizes.

Typically these types of filters appear in mostly non-standard sizes, depending on the original equipment manufacturer specification. Our custom capabilities allow us to fabricate to any size requirement.
