Owning the Expobar Office Lever
The Expobar Office Lever is a compact, traditional-style heat-exchanger machine with commercial levels of strength. We think it’s a step up from the other Office machines, with its all-over use of stainless steel, as opposed to a combination plastic-stainless look, and the addition of pressure gauges. As a heat-exchanger, the Office Lever is capable of simultaneous brewing and steaming through Expobar’s reimagined E61 group head, which uses a thermosyphon throughout the brew circuit to ensure temperature stability, and an integrated concave pre-infusion chamber for evenly saturated extractions. We’re particularly fond of the brew pressure and boiler pressure gauges, which allow you to monitor each while pulling shots. Internally, the machines are made up of high-quality components, switches and controls, most notably the electronic boiler refill control, which acts as a brain of sorts, refilling the boiler each time it nears empty. To remove refills altogether, the Office Lever Plus model offers a plumbability option for even greater convenience.
Upon flicking the switch, the boiler will heat up to brew temp, as designated by both the indicator light and the pressure gauge reaching 1 bar. Raising the brew lever controls a valve in the brew group: up activates the pump and opens the valve to allow water to flow through the grounds; down opens a valve that relieves the water pressure from the coffee. The Expobar Office Lever is compact, and perfect for the serious home, office or small cafe barista. Also part of Expobar’s Office Line are the Control, which offers programmable volumetric brewing at the press of a button; the Pulser, which is similar in looks and operation to the Control sans programmable buttons; and the Office Lever Plus, which adds a plumbability option to all the great features the Office Lever already boasts.
