For all Expert and 3000 series drums. Unlike the other JOBO system tanks and drums that use a sliding ring closure, the Expert and 3000 serires drums have a friction-fit lid. This lid can sometimes be difficult to open by hand but pops off easily if slight air pressure is build up in the drum. To open the drum lid of any 3000 series drum fast and easily, we recommend to use this foot pump.
The tank lid of the Jobo Expert and 3000-series developing drums is fitted onto the tank using a friction-fit closure system which ensures a leak-free development. Since the tank doesn't use a sliding-ring closure system, it can sometimes be difficult to open the drum by hand.
The Jobo 3360 Foot Pump eases the opening of the drum by building up air pressure inside the drum so the lid jumps off. An essential tool if you're using an Expert or 3000-drum frequently!
