Min. pressure
The minimum pressure of water at the exit provided by a minisink. This parameter is indicated only for models in which the pressure can be regulated; for other cases, only the maximum (it is standard) pressure is indicated, see below about it.
High pressure during washing is not always desirable: on the one hand, it increases the cleaning efficiency, on the other hand, it can damage the treated surfaces. Therefore, in some cases — in particular when working with delicate materials or using foam — it is necessary to work at a reduced pressure. Detailed recommendations on this matter can be found in special sources, but here we note that the minimum washing pressure should not be higher than the maximum allowable — otherwise the unit simply cannot be set to the desired mode.
Max. pressure
The maximum outlet water pressure provided by the miniwash; for models in which the pressure is not regulated, this paragraph indicates the standard operating value.
The higher the water pressure at the outlet, the more efficiently the unit handles with chronic and stubborn contaminants. On the other hand, strong pressure requires high engine power, which affects the dimensions, weight and price of the device — despite the fact that not every dirt requires such pressure, and excessively intensive washing can damage the surface to be treated. Thus, the pressure is chosen by manufacturers in accordance with the general class of the miniwash. Thus, values
up to 100 bar are found in the most compact and low-power domestic models (see "Type"). A pressure of
100 – 125 bar is considered relatively low for household sinks, and most of these models are in the range of
125 – 150 bar — this is most often quite enough, taking into account the characteristics of the application. For professional units, the average is considered to be
150 – 175 barhowever, there are many models that give out
more than 175 bar.
Power
Power of the pressure washer motor expressed in watts. Such a designation nowadays is generally accepted for all types of engines; it is quite possible to compare electric and gasoline / diesel units with each other. At the same time, for sinks with internal combustion engines, power in horsepower can also be specified (see above), but most often it is indicated as an addition to watts.
The higher the engine power, the greater the performance and pressure can be achieved at the outlet of the miniwash. On the other hand, this parameter directly affects the cost, as well as fuel / electricity consumption. In addition, in some situations, high power is unnecessary — for example, a delicate surface can be damaged by strong pressure. So when choosing, it is worth considering specific tasks, and not chasing the maximum possible power.
Detailed recommendations on this matter for different cases can be found in special sources. Also note here that most household models (see "Type") have a power of up to 2 kW (
battery units — most often up to 100 W, although there are exceptions).
2 – 3 kW are considered a fairly solid indicator for household sinks, and values \u200b\u200bmore
than 3 kW are already found mainly among professional models. Professional equipment, however, is also low-power (
up to 2 kW), but there are few such dev
...ices — in general, the power of such units is quite high, in a fairly large number of models it exceeds 4 kW.
