Ascaso Steel Uno Professional V4 - 2 Colours
In 1962, Jesus Ascaso founded the Ascaso Factory in Barcelona, Spain. The Ascaso enterprise kept on growing until it became a major brand in the world of home and professional espresso machines. It creates espresso machines and coffee grinders with long lasting components where durability and professional performance are the rule.

The term 'Professional' used by Ascaso signifies that the grouphead and portafilter accommodate 58mm diameter sized filter baskets like that found on commercial machines. The Ascaso Steel Uno Professional V4 offers a marvelous combination of style and performance, allowing you to create quality espressos, cappuccinos and lattes at home. The solid specification of this machine includes commercial-sized filter holder, 68 oz water tank and 3-way solenoid valve. Plus, the black stainless steel finish and cool blue LED's will make Uno Professional V4 the star of your kitchen.


Commercial Grouphead

The grouphead (the part that accepts the portafilter) of the Uno Professional evenly distributes heat and reduces 'hotspots ' for more temperature consistent espresso. It has also been designed to evenly distribute water across the coffee grounds for better extraction. The marine grade brass is chrome plated for corrosion resistance and easy cleanup.


Its high quality means it can reach working temperatures quickly and in succession. Two thermostats control the temperature of the coffee and steam and a resettable thermostat protects the machine from accidental overheating. High capacity. Oversized to guarantee professional thermal stability and provide quality in every cup. The water circulates through an Inox circuit, reducing lime scale build-up to a minimum. Provides a limitless supply of steam.

3-Way Solenoid Valve

The three-way solenoid valve is a commercial feature that relieves the water pressure off the coffee when the brew switch is turned off. The valve dries out the used ground coffee in the portafilter immediately after the brewing is finished. So you can straight away remove the handle, easily knock the dried coffee out and reset of the machine for another shot. The Steel Uno also features an adjustable over pressure valve that can be adjusted from 8 to 15 bars.

Vibratory Pump

The Ascaso UNO Professional boasts a powerful vibratory pump rated at 15 BAR of pressure to extract maximum flavor from the coffee beans.

No Burn Steam Wand

A multi-directional steam wand has an excellent range of motion for ease of use. It creates fine and creamy milk foam effortlessly for your cappuccino and latte. Hot water wand is also on a ball joint making it easy to pour water into a cup.

Easy to Use Controls

The grouphead is controlled by a simple push button that activates the vibration pump and opens the group solenoid valve to deliver coffee. Once the desired quantity is reached, press the push-button again to stop brewing.

Commercial Portafilter

The Uno Professional uses heavy-duty chrome plated brass portafilter holders and spouts. The machine comes equipped with commercial grade 58 mm filter baskets to make it easier to find a quality tamper that suits your taste. You can use the same filter holder for both ground coffee and pods. The Ascaso Steel Uno Professional V4 includes 3 stainless steel filter baskets- separate single shot and double shot filter baskets for ground coffee and one single pod filter basket for ESE (Easy Serving Espresso) pre-packaged pods.
The new porafilter handle has a non slip grip and it is tilted 10 degrees for easy use. If you place the portafilter on flat surface it is perfectly level making tamping a breeze.

Water Reservoir

The 68 ounce water tank is removable from the right side of the machine. You may refill the water tank any time during the operation or remove the tank to refill at your tap. In addition, one of the blue LED indicators will notify you when the water level is low.

Removable Drip Tray

You can easily slide out the plastic drip tray for easy cleaning. Front portion of pull out drip tray is in brushed stainless steel.

Cup Warming Surface

Warm espresso cups are essential for great tasting espresso. The Uno Professional offers a passive cup warming surface on top of the unit to ensure that espresso doesn 't lose temperature when poured into a cold cup.


The Ascaso Steel Uno Professional comes with a detailed instruction manual, filter handle with dual spouts, single cup filter basket, double cup filter basket, pod filter basket and a aluminium tamper.

The new Version 4 of this machine includes a no burn multi-directional steam wand which is the best steam wand we have seen on a single boiler/thermoblock machine. The machine also comes with a black stainless steel body. is pleased to announce that we will be working directly with Ascaso and representing them here in Canada.
