This upgrade kit solves one of the pesky little issues of the Apex Manual Coffee Grinder - coaxing the last few beans into the burrs! We made a tooling change for the hopper window to include a strategically placed hole that mates with this particular Air Blower. Through experimentation we figured out the best placement of the hole for blowing down beans & fragments into the burrs so they can be ground up... Drilling a hole in your current hopper cover can be kind of difficult - the plastic can sometimes crack (we cracked a lot of them....) This window with hole, and blower is standard on the most current Apex build.
Air Blower measures 15cm x 5cm diameter including the 5cm nozzle. Nozzle hole is about 1.5mm in diameter.
