We know pressure washers. Find the answers you're looking for right here.
Pressure washing or power washing is the growing practice of cleaning using high pressure water spraying. The high pressure water spraying is achieved by specially designed pumps. This type of cleaning is many times more powerful than the pressure that comes out of a typical garden hose. If you choose to use on concrete it removes mold and mildew, bubble gum, and other dirt stains. Also, pressure washing can make wooden decks look like new. Pressure washers are also commonly used by homeowners to improve the appearance of aluminum or vinyl siding by removing pollution, mildew, and other signs of neglect.
Belt driven pressure washer are most commonly found on commercial/industrial style pressure washers. A belt driven pump is ideal for cleaning applications that require more than 20+ hours per week. On a belt driven unit, the high-pressure pump spins at a less RPM reducing the heat and vibration, which in turn, minimizes the wear and tear on the internal parts of the pump and leads to longer life.
If you will be using your pressure washer less than 20 hours a week, a direct drive may be better suited for your application. Direct drive units turn about twice the RPM as a belt driven unit. These units are usually more compact and easier to transport. They also typically are more cost effective.
Gas or electric is completely up to the consumer. There are pros and cons to both.
电is safe to use indoors because you don't have harmful fumes. Electric motors are usually quieter and require less maintenance than a gas engine. Also, with an electric motor you do not have to have gas on hand and you do not need to fight the rising cost of fuel prices.
With a gas pressure washer you have a couple of different choices when selecting an engine. Also, gas engines don't require a power cord which in turn allows more portability.
PSI and GPM are both equally important when choosing a pressure washer. The PSI refers to the amount of pressure and GPM refers to the flow. You must have the correct combination of PSI and GPM to have the most ideal pressure washing system for your needs.
PSI (Pounds per Square Inch) refers to the amount of cleaning pressure that the unit can produce.
Cleaning Units (CU) is the result of multiplying the PSI by the GPM. Cleaning units gives the customer a measure of unit performance (efficiency) to compare one unit to another. Cleaning units is calculated by multiplying PSI and GPM.
- A pressure washer with 3000 PSI and 2.0 GPM has 6000 Cleaning Units
- A pressure washer with 2000 PSI and 3.0 GPM also has 6000 Cleaning Units but the rinsing power is greater than the stripping power.
GPM is usually more important to contractors than PSI. Since most contractors use cleaning chemicals to do all of the cleaning, their job becomes one primarily of rinsing the dirt away.
Rotating nozzles increase your cleaning power and decrease your cleaning time. Rotating nozzles offer spray impact with 25-degree coverage. Mi‑T‑M Nozzles include a filter, to protect the nozzle from becoming clogged with debris, a quick connect and heavy-duty components for long life and reliability. Rotating nozzles can be used on sidewalks, driveways, track vehicles, muddy areas, old peeling paints and concrete surfaces.
Hose reels are convenient for the storage of hoses and can be mounted directly on pressure washer frames or attached to a wall bracket. Several sizes are available.
