Features Specifications Performance


Uncomplicated and capable are two words that accurately sum up The Expobar Office Pulser semi automatic espresso machine.

True to its professional machine heritage, this Expobar is the culmination of commercial grade, high quality construction and user-friendliness. It features a heavy-duty heat exchanger boiler so you can brew and steam at the same time. A powerful pump and commercial caliber brew group with a dynamic E61-type group head complete the brewing muscle behind this machine, making it ideal in a multitude of settings – from home to office to even a salon or small bagel shop.

From an ease of use standpoint, the Office Pulser works like this: Fill the chrome-plated portafilter, tamp your coffee, lock it into place, press the brew button and you’re done. No complicated programming or bells and whistles to get between you and your coffee. The separate hot water dispenser and steam wand are also designed with ease of use in mind, mounted on a 360-degree ball joints, and operated simply by turning the corresponding black knobs on the control panel.

All this strength is packed into a compact footprint of 15.25"H x 9.5"W x 16.5"D, and housed in handsome stainless steel to compliment any counter surface you put it on. The cup warming area on the top is also stainless steel, as is the matching drip tray cover that sits atop the easily removable matching hard plastic drip tray.

Form. Function. Durability. The Office Pulser is yet another shining example of Expobar’s dedication to espresso machine craftsmanship and quality.

Simple Controls Leave You in Charge - The Expobar Office Pulser controls couldn’t be simpler. Just turn on the main power switch (the red rocker switch behind the hot water wand) and the boiler will fill with water on its own and start to heat up. When you turn the machine on, the round, red temperature light goes on while the boiler is filling and heating up. When that light goes out, you are up to temperature and ready to brew.

Stainless Steel Housing & Steel Framing - Inside, a strong, durable steel frame holds the Pulser together. And outside, a stainless steel housing encases it. This housing, while beautiful, is also highly functional, making the machine easy to wipe down, and tolerant of a lot of day-to-day wear.

Powerful Pump for Perfect Pressure Brewed Coffee - The Office Pulser’s pump is a powerful self-priming vibration pump capable of putting out as much as 15 BAR of pressure. It operates a brewing pressure of 8 to 9 BAR – which is the ideal pressure level for extracting espresso.

Commercial Caliber Brew Group, E61-type Group Head & Portafilter - True to Expobar’s professional espresso machine roots, The Office Pulser has a commercial caliber brew group of solid chrome-plated brass and features a 3-way solenoid valve. The star of the whole assembly is the E61-type group head, which is the round piece of chrome-plated brass the portafilter locks into. It is channel cut – thermal siphoned – which allows the water to circulate through it before being pressure forced across the coffee grinds n the portafilter. The Pulser also pre-infuses the coffee, in order to extract the most flavor and aroma from your grind.

3 Way Solenoid Valve - The three-way solenoid valve is a commercial feature that relieves the water pressure from the machine when the brew switch is turned off, making it possible to immediately begin brewing again. It also pulls the excess water out of the used coffee grinds in the portafilter, making the puck easy to knock out of the portafilter cleanly. It then deposits this water into the drip tray, and you’re ready to reload and brew again.

Copper Heat Exchanger Boiler System Complete with Safety Features - The large 1.7-liter copper boiler with brass end plate takes about fifteen minutes to heat up. Once it is up to operating pressure, it can brew continuous espressos all day long, and in under 25 seconds each. Due to the boiler’s large size, The Office Pulser can also pump out consecutive lattes and cappuccinos without any down time. And because it’s a heat exchanger, you are able to brew and steam at the same time – a nice feature if you’ve got multiple users at the machine or making multiple drinks at once.

Ball Joint Mounted Steam Wand - The stainless steel steam wand is long and is high enough off the counter to easily fit any frothing pitcher without having to tip it. It is mounted on a ball joint that can swing in any direction. It also has a heat resistant grip so you don’t burn your fingers when you’re using it. To begin steaming, just hit the steam button and turn the steam knob. It can heat 8 ounces of milk in a speedy 64 seconds.

Ball Joint Mounted Hot Water Dispenser - The Pulser’s hot water dispenser is made of a durable, sleek stainless steel and is mounted on a ball joint so it can pivot in any direction, making it easy to access for any size cup, mug or pitcher. Also you can use it to pre-warm your cups to keep your espresso nice and hot. Simply turn the black knob on the right side of the control panel and start pouring.

Heated Cup Stacking Surface - Preheat up to 14 espresso cups at one time using the passive cup warmer on the top of The Office Pulser. Passive means it doesn’t have its own heating element, but warms using the heat the boiler gives off. The surface is stainless steel so it’s easy to wipe down.

Removable Drip Tray & Drip Tray Cover - The drip tray is made of durable matching plastic so it can handle continual use. It holds up to 32 ounces of excess water and coffee, but easily slides on and off for emptying. Atop it, sits the stainless steel drip tray cover that pops right out for cleaning.

Removable Water Reservoir - The removable, 2-liter reservoir is made of durable ABS plastic for years of service. It can easily be removed for cleaning, and refilling.

Accessories - The accessories include a chrome plated brass portafilter, tamper, single shot filter basket, double shot filter basket and a 7-gram coffee scoop.
