Will my rotary vane air pump interchange with a linear?

In many cases it will. You should check with your manufacturer to guarantee proper sizing; however, a good rule of thumb would be that the Model 0323 rotary vane is equivalent to the 80 liter linear and the Model 0523 rotary vane is equivalent to the 100 liter linear.

What are the advantages of a rotary vane?

They are extremely durable and usually will outlast a linear air pump in average life expectancy.

What are the disadvantages of a rotary vane?

Rotary Vane Pumps are loud and usually use twice as much electricity as a linear.

What are the advantages of a linear air pump?

Although not quite as durable as a rotary vane compressor, a linear air pump runs extremely quiet and uses approximately 1/2 the electrical consumption of a rotary vane. If your on-site system is located in an area where you can hear it, such as your backyard, you might want to use the much quieter linear air pumps.

What are the disadvantages of a linear air pump?

The linear will need to have the diaphragms replaced more often than the rotary vane compressors will need to have the vanes replaced. Although the electrical savings of a linear versus rotary vane will easily make up the difference.
