Clark Air Systems utilizes the longest life, lowest maintenance filters available: 

1st Stage:
Multi-ply, depth loading, Cube filters with tackafied media. The large amount of media in the air cleaner is designed to keep maintenance to a minimum. These 45% efficient filters catch the bulk of dust and dirt.

2nd Stage:
The mini pleat captures up to 95% of fine particles to increase the life of the HEPA filter significantly. The ease of access and high capacity simplifies the operators job significantly and increases efficiency.

3rd Stage: 
99.97% DOP certified HEPA filter with gasket seal to meet strictest codes. 99.97% removal of 0.3 micron particles. 

Replacement of filters periodically. Only a few minutes are required to replace any filter. The frequency depends on conditions. Average one year on the final HEPA filter. 

The units are constructed with extra durable lightweight rigidized aluminum. Hinged, gasketed door allows easy access to all stages of filtratiion. 
The unit's modular design allows for ease of use in and out of confined spaces. These units were designed specifically for duct cleaning operations on ships and are currently in use in the cruise industry as well as the US Navy. The unit is portable with industrial grade locking casters.
