Currently, you can find a great variety of disposers from various producers on the market. As with all products, even in the area of disposers there are several construction variations with more or less enhanced individual features. These differences, invisible at first sight, can have a significant impact on the process of crushing, on the lifespan of the disposer, its utility characteristics and the overall comfort of use. Since the product is relatively unknown in our country and the consumer does not have many possibilities how to find information when choosing one, we will try to familiarize you with some different parameters.
possibility of removal during cleaning or replacement because of wear
The disposer is usually hung in the opening of the sink by its neck to which the crushing chamber of the disposer is connected directly. In the neck, there is always a rubber splash guard – that is a dirt collector - that encloses the chamber. If no other leftovers are being pressed through, it prevents minute particles of crushed waste and water to fly off back into the sink. In the course of this process, a layer of impurities is formed on the bottom side of the splash guard, which is necessary to be removed from time to time, so that undesirable odor is not produced. If the splash guard is removable directly from the sink, cleaning is quite easy. If not, you need to try hard to clean it from the bottom or to dismantle the whole disposer and to separate it from the neck, so that the splash guard could be removed. The same applies for its wear and replacement. Another disadvantage is a bad access and visibility into the chamber, if you try to take out a foreign object that falls into the disposer by accident (cutlery, bottle cap).
resistance against corrosion, firmness, noise suppression
In the production of crushing chambers, various materials are used, which can be an important factor for your choice. The basis of all is corrosion resistance, firmness and possibly noise suppression. During the crushing process, the chamber must resist against impact of the crushed material, such as fragments of bones, sometimes also a foreign metal object etc. What proves most useful with domestic disposers is a mixture of polyester and polyamide filled by glass, which is firm, light and suppresses and does not transmit noise. Further, what is used is also a suitable rust free or enameled sheet metal, which unfortunately corrodes when flaked, which results in the disposer being put out of service after some time.
corrosion resistance, temper
Nickel-plated steel and stainless steel is used, blades are from rust free sheet metal or they are cast from stainless steel. Industrial disposers can also have blades (with brass welded-on edges) from hard metal, used also as tool-making steel.
start-up, revolutions, weight
Disposers use both induction engines and engines with permanent magnet. Each of these engines has its own specifics and is suitable for a different purpose.
An engine with permanent magnet has high revolutions 2600 - 2800 rev/min. It reaches these revolutions virtually immediately, so it is suitable for domestic disposers, where an immediate performance and speed plays the main role; it thus prevents possible jamming of the disposer by waste and it guarantees faster crushing. Moreover, they are small and lightweight, so they can be also attached under sinks with thin walls and do not take up space in the sink cabinet. Their disadvantage - when used in larger facilities - can be the untimely wear of carbons that must be replaced, and the fact that it is not possible to crush ceaselessly, as the engine would overheat.
The induction engine is slower, it reaches about 1400 - 1725 rev/min. It uses a startup condenser and until it reaches its full performance, there is a threat of jamming of the disposer by an untimely thrown-in waste. They have greater size and weight. They are perfectly suitable for industrial disposers used in gastro operations. They can run ceaselessly without pauses, they have no carbons, so they do not show any significant wear that would require early maintenance or repair.
TV and radio shielding
Cheaper models can lack anti-interference filter, so the crushing jams radio or television signal.
connection of a dishwasher, washing machine
What can be useful is an optional additional entry for a draining hose of a dishwasher or washing machine, without necessity of other interventions and modifications of the waste pipeline or replacement of the siphon for another type, if it is even possible without major complications.
50 years and more
Experiences of a long-standing producer will certainly reflect in the quality and overall machining.
assortment of various types
The greater the product line of disposers, the better you can choose the type that will suit your needs with regard to the acquisition costs.
quality control
The disposer must comply with the harmonized European standard marked CE. Observance of quality of the product and of the process of quality control may be additionally verified by the quality certification ISO. If the product has this marking, it is manufactured by a very respectable producer, where the quality is paramount.
25 years
The product can have its lifespan stated somewhere, so look for it.
A higher guarantee period than one stipulated by law (2 years) indicates quality. The disposers EcoMaster are delivered with up to 6-year guarantee.
possibility of assembling, consultancy, customer service, references
The supplier or seller can also provide consultancy, realization of a professional assembly and after-guarantee service and possibility of purchase of spare parts.
The above mentioned parameters in sufficient values are off course fulfilled also by disposers of other brands! E.g.: Waste King, Bone Disposer, Waste Maid, Sinkmaster, Whirlaway, Commander.
