Pressure washer gpm needed.

Water pressure is measured in psi. The psi is necessary to break the chemical bond between the surface and the stain. Remember if you re never going to exceed 2500 psi then you can save some money by choosing a 2600 psi pressure washer over a 3000 or 4000 psi pressure washer. These pressure washers put out 2800 psi and higher at 3 to 4 gpm.

This pressure is more than a garden hose. Gas powered pressure washers typically put out more psi pressure compared with electric models. For the toughest deep cleaning jobs consider 3100 psi pressure washers. Higher gpm is needed for any seriously large or fast cleaning job.

Let me give you an example. A typical water hose will produce more gpm than most any pressure washer can use. On the contrary this pressure is too less to clean parking areas stained with tar. This is ideal for deep cleaning concrete stripping paint or graffiti and more.

The pressure put out by a power washer is measured in psis pounds per square inch. Commercial grade pressure washers are included in this group starting at 3100 psi. Commercial pressure washers are great for the toughest of stains and paint prep. Or cleaning off a patio etc.

You buy a 2 8 gpm unit. The gpm of a commercial pressure washer can be up to 4 0 gpm. The larger the gpm the more surface area a pressure washer can clean. The durable machines make light work of many large scale cleaning jobs including graffiti removal paint stripping and washing two story homes.

The gpm number on the pressure washer has to match the capacity or the pressure of the water supply. Psi rating isn t the only spec to keep in mind when pressure washing however there is also the gpm rating gallons per minute. Even if the gpm water flow of your water supply is just a little bit lower than the gpm specs of the pressure washer you can wind up ruining the unit. A little 2 5 is fine for washing your car.

With wood you will need a stronger pressure washer because you ll need the strength for spraying away the mold and the mildew. Learning how much pressure is required to successfully clean different surfaces materials or objects will help you determine what size pressure washer you would best benefit from. The exact or a range of psi required is what the pressure washer psi chart reveals. It is said in the pressure washing industry that the pressure psi does the cleaning but the water flow gpm cleans it faster.

Pressure washer psi and gpm work together to provide the most efficient cleaning. Gallons per minute gpm water flow is measured in gpm. Unlike cars you won t scrape away the finishing of the wood furniture.
