  • Steam. Unlimited steam supply. Constant pressure. No damage to the heating element caused by low water levels. Reliability and quality.

Fixed Filter Holder

(coffee pods only)

Our fixed filter-holder system features an exclusive patented design which allows ease of use and superb ESE coffee pod removal. The thermoblock also makes unlimited steam production possible.

Mobile Filter Holder


This system allows the use of both ground coffee and ESE coffee pods. The thermoblock also makes unlimited steam production possible.

Professional Group

Coffee group is manufactured lead free brass.

Professional Filter Holder

Following the Ascaso philosophy of transferring professional components from the espresso coffee world to the home, all our machines feature a nickel-plated brass filter holder with stainless steel filter (for 1 or 2 coffees) and a special filter for ESE coffee pods.

Thanks to its ergonomic design, it has a strong yet pleasant feel. Non-slip grip. It is tilted 10º for ease of use, while the horizontal placement of the filter holder in the delivery group ensures perfectly pressed coffee grounds.

Professional Filters

As well as the traditional filters, Steel features the latest coffee-making technology, with the new ‘super-froth‘ filter for an extra-frothy espresso. These special pressurised filters for 1 or 2 cups ensure the frothiest coffee regardless of the coffee blend or grinding method used.

6 professional filters standard (2 traditional, 2 pressurized, 1 blind and 1 monodose E.S.E.)

Just Filters?

The coffee filters on all our machines are of the very highest quality. Quality materials (AISI 304) and manufacturing.
Our cutting-edge production process guarantees optimum results time after time. Filter by filter. Hole by hole. If not, there will be significant differences in the cup and dispensing alterations.

The circular perforations are totally uniform and always the same size (maximum tolerance of 0.02 mm difference between one hole and the next).
Its design (a geometric pyramid for the holes and a 94º angle) guarantees uniform dispensing and reduces possible sediment in the coffee and the blocking of the holes.

20 Bar Pump

The professional water pump passes water through the coffee at the correct pressure to extract maximum aroma, flavour and organoleptic characteristics.

3-Way Solenoid Valve

This type of valve allows the machine to offer dry dispensing, eliminating the final drips and preventing over-pressurisation. Made in all cases of lead-free brass (OT 57) and stem of AISI316 stainless steel.

Professional Steam Valve

New, exceptional quality. Highly durable. Simple and inexpensive to repair.
TFM (high performance) gasket closure system.

High Quality Shower

Without welding. AISI304

Electronic Technology

Cutting-edge electronic components. ‘Tropicalized’ chipset. Intelligent steam management in the thermoblock.

Electronic Thermostat (adjustable)

Thermal stability ±1,5ºC.
(Optional in ZERO model)

Fully Independent Electronic Temperature Control

For each group, (up to 8 possible options ranging from 90°C to 106°C). We guarantee a maximum deviation of +/-1.5°C. In continuous or intermittent use. From the first coffee to the very last.

The traditional boiler and bimetal thermostats offered a deviation value of up to +/-5°C.

Stable and Professional Steam Management

With electronic management, the amount of water entering the group is based on the machine’s temperature (not on the amount of water inside, as in the case of the boiler), by changing the pump activation frequency, thereby always producing dry steam.
The steam pressure in the first 10 seconds is superior with the boiler system but, as no water is added, that pressure runs out over time. With Thermoblock, the pressure is continuous and unlimited.

The boiler system is much less reliable in terms of element durability. Lack of water causes the system to ‘struggle’ when using steam services. Additionally, in the boiler system, use of a steam service requires the user to fill the boiler manually afterwards.

Temperature Control

The external thermometer, with its retro design, tells the temperature of the coffee group.
Twin ºC – ºF scale.


Electronic PID Coffee Group Temperature Control

Adjustable in one-degree increments.
Electronic steam control.
Stand-by option available.
Coffee dose timer.
Programmable pre-infusion. (0 to 5 seconds).
Alarms (5): Water/coffee ratio, coffee or steam gauge, coffee group or steam. (Display indicates error type).


Externally adjustable pressure valve.

Dose Control Based on Water/Coffee Ratio

Two options: Small or Large coffee

Pressure Gauge

Along with the PID temperature control, this enables complete control of the machine.

Heat-Resistant Steam Nozzle

Stainless steel. Multidirectional 360°. Heat-resistant. Easy to clean.

Thermoblock Thermal Cover

Significantly reduces energy consumption and increases thermal stability in the group

Cup Warmer

Cutting-edge electric cup warmer (consumption 10W). Keeping the right temperature for your coffee glass.

Ø60mm Filters

Ø60 mm professional group. Ensures you to have beautiful crèma everytime without hassle.

Wooden Handles and Knobs

Ergonomic. Warm natural feel. This professional yet classic group head handles and knobs from ascaso is a beautiful and timeless, this handle and knob will completes the uique accents on your ascaso machines.

Water Reservoir Light

Makes it easier to see the water level and improves the look of the machine.
