Owning the Expobar Office Lever Plus

The Expobar Office Lever Plus is a welcome upgrade to the Office Lever design.

With it, we see the insulated steam wand, and, the clincher for our admiration, a plumbability option for direct connection into a water line. Its optional plumbability makes the Office Lever Plus a stand out among heat-exchangers, not only in the Expobar line up, but across the board. You’ll never have to refill the boiler again, and you can install an inline water filtration system, such as BWT, to remove the need to descale the machine and improve longevity. Plus, the Office Lever Plus retains all of the functionalities that have made it an industry benchmark: simultaneous brewing and steaming, dual pressure gauges, and Expobar’s thoughtfully reimagined E61 group head, which uses a thermosyphon to ensure temperature stability and an integrated concave pre-infusion chamber for evenly saturated extractions. At the price point, the Office Lever Plus offers amazing functionality at an incredible value.

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 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 convenient for heavier use when plumbed in; 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 standard Office Lever, which is the same great machine as the Plus without the plumbing option.

Direct Water Line Connection

Direct Water Line Connection

The Expobar Office Lever Plus can be plumbed; this gives you the option of connecting the machine directly to a water source for an endless supply of water instead of relying on the water reservoir. A safety solenoid valve works in parallel with the pump to prevent leaking. To remove the need to descale and improve your machine’s longevity, install a BWT filtration system inline.

Heat-Exchange Boiler

Heat-Exchange Boiler

The Pulser’s 1.7 L heat-exchanger boiler has an internal chamber that houses the brew water, while the steam is cordoned to the surrounding chamber, preventing them from coming into contact. This design heats the brew water and allows for simultaneous brewing and steaming.

Redesigned E-61 Group Head

Redesigned E-61 Group Head

A standard E-61 group constantly syphons water from the boiler to the group and back, but Expobar raised the bar by adding a pre-infusion chamber above the shower screen. This innovative addition evenly distributes hot water over the grounds for a uniform saturation during pre-infusion and throughout the brewing process.

Boiler Pressure Controller & Gauges

Boiler Pressure Controller & Gauges

This controller automatically senses drops in pressure within the boiler and kicks the heating element on, which is visually represented on the pressure gauges. These gauges also make it easier to monitor extraction parameters while brewing, or after you’ve made an adjustment to boiler pressure using via the OPV or boiler pressure via the pressurestat.
