Thanks to a wide range of accessories the high pressure washers may be used for different applications and uses. Comet markets an extensive catalogue of accessories for high pressure washers for both domestic and professional use to ensure excellent performance for every type of use.
It’s connected to the high pressure washer’s delivery hose and is used to control the jet and determine through a lever whether the water is flowing out or not. A lance is attached to its end.
The guns with flow regulator also allow modulating the force of the outgoing water jet, thus regulating the pressure and flow rate at the nozzle of the lance proportionally.
This is a rigid metal or plastic tube that is connected to the gun by means of a quick coupling. At the opposite end of the head is fixed the nozzle from which the pressurized water flows out. There are different types of lance, depending on the type of use they are intended for: high pressure lances (straight or angled) with fixed head or with detergent suction regulation for washing and application of detergents, or foam lances equipped with a tank for dispensing sanitizing detergents. The detergent mixed with water using the “Venturi” system generates a thick and effective foam.
In the Comet range we also find sand-blasting lances, which are particularly useful when removing rust, paint and incrustations; the jet power is, in fact, amplified by the water-mixed sand or soda sucked in by the probe.
The nozzle is a device designed to spray water with a certain shape and direction. The nozzles can be made of brass, stainless steel or ceramic and are distinguished by the shape of the jet:
Concentrated or 0° grade jet nozzle: the water comes out of the nozzle orifice forming a concentrated jet whose internal volume is filled with drops; it is suitable in case of very concentrated and resistant dirt.
Flat or fan-shaped nozzle: the water comes out of the orifice forming a fan-like jet, with an opening angle normally between 15° and 40°; this is the most suitable solution for most surfaces.
Rotating nozzle: the water comes out of the orifice forming a rotating conical jet, where the drops are distributed only on the outer surface, improving the cleaning effect. The rotating action does in fact increase the impact pressure on the surface.
The choice of the most correct nozzle therefore depends on its use, the more resistant is the surface (and the dirt’s concentration), the smaller will be the opening angle width to be used. Conversely, the more delicate is the surface (or surface dirt) the greater will be the angle.
Each application has its own specific nozzle like the nozzles for pipe flushing probes.
This is the hose that connects the high pressure washer to the gun. A standard hose would not be able to withstand the high pressure generated by the flow of water through it. The delivery hose is then reinforced with single or twin (metal or plastic) plaits and several layers of high density rubber.
The heads have a dual function, they connect one or more nozzles at the same time to the lance and at the same time protect them from shocks or external stress, so as to limit wear. Depending on the type of use or need, it is possible to choose from nozzle holder heads, detergent suction heads, double and triple heads for mounting more than one nozzle, heads for sandblasting lances and for pipe flushing probes.
To cover the different areas and needs for cleaning and sanitation, the high pressure washers can be equipped with a complete range of fixed and rotating brushes ideal for car-wash as well as surface cleaners for washing outdoor areas: patios, pavements, walls. The Comet range of accessories also includes a complete kit for washing solar panels equipped with telescopic extension and ultra-light surface cleaner. A gutter washer kit can also be implemented on request.
In the Comet range of accessories for domestic, semi-professional and professional high pressure washers, we also find: ejectors, swivel couplings, filters, hose reels, descaler dispensers, and other accessories dedicated to specific uses or particular needs.
