We have had several phone calls lately about problems with equivalent filter elements for ZEKS air dryers and filter housings. We have discovered there are two versions of the ZEKS E100G filter. 

One version does not fit inside the ZEKS filter housing due to an incorrect design of the top of the filter. As you can see in these customer pictures, the top inlet design is different and one will have to be sent back.  

The correct design and dimensions for the top of the E100G filter are illustrated above. The Inside Diameter should be 1.57-inch and the Outside Diameter should be 2.17-inch. The Overall Height of the correct Zeks E100G filter is 8.86-inch. This is a 1.0 micron filter replacement. 

If you have any questions or concerns about the E100G or any other ZEKS filter replacements, feel free to contact us to confirm you will receive the correct filter.
