Although gas pressure washers need more maintenance, use fuel, lubricants, and are a bit noisier than electric models, the smallest gas power washer is stronger than the largest electric washer…and it is portable. Gas pressure washers can be used in remote places and generally have more durable pumps than electric models.
When purchasing a pressure washer, always consider the pump. Is it commercial grade with a brass head? Does it have ceramic plungers and stainless steel valves? Preferred industrial pumps for pressure washers are Cat, General, or Comet pumps. They are triplex pumps with above-mentioned ceramic plungers and stainless steel valves. Always improving, there are now Cool-drive pumps that reduce heat build up 25% more than belt driven pumps. If you are planning on going into the business, or are already in business, you may want to consider a Cool-drive pump the next time you purchase a pump.
Good gas pressure washers should come with chemical injection capability and have several different size nozzles (one adjustable tip sounds handy, but it is nice to have more options), and pneumatic tires. The Briggs & Stratton engine or Honda engines are the most popular power sources for pressure washers.
There are at least eight gasoline models to choose from. Most have stainless steel mounting and thermal relief valves to prevent pump overheating, large gas tanks, insulated lances, hi-rated trigger guns, and 50’–100’ of non-marking pressurized hose. There are also units that are made to mount in the back of a pick-up truck. Other options are power washers that come with their own water storage tanks with 50–300 gallon capacities, swivel hose reels, and roto-molded tanks with automatic shut-off in case the machine runs dry.
Whether you are a homeowner needing only 2,000-4,000 PSI pressure washing power, or a contractor or industry requiring from 3,000-5,000 PSI capability, there is a power washing system for you. From cleaning gutters and toys, to stripping paint or unclogging drains for customers, to industrial duct, sewer, and equipment cleaning, gas pressure washers are real time and money savers for everybody.
