This is a vintage EHEIM model 2010 39 "Mini-Filter" that was manufactured over 40 years ago. The pump still runs, however it is now more of a collector's item than an aquarium filter option.

The flow rate is only 1.5 liters per minute-about 23 gallons per hour. Eheim considered this to be a type of small canister filter featuring a "trickle" flow rate of biological filtration. 

All of the filter blocks are long gone but the lid, filter box and intake tube are original and intact. 

The strainer assembly on the intake tube has been replaced. 

An extra working pump salvaged from another model 2010 is included in the lot

The reason I am describing this filter as a "collector's item" is that I want the buyer to understand what they are purchasing. It can be difficult to prime/start and it is over 40 years-old.

This unit has been part of my collection of "ancient" aquarium gear for a long time, but I am moving overseas and can't take it with me. All sales final. No returns.

Thank You for Looking!
