D & M Products - About Us  
  D & M Products was established in 1938 by Carlton Peterson who designed and engineered our pressure washing gun. Designing helicopter transmissions for Hughes Aircraft by day, Mr. Peterson filled his nights and weekends with his own engineering projects. He saw a need for a low cost alternative to expensive self-contained pressure washers. He reasoned that many businesses require a fast and effective means of cleaning machinery and work areas.

D&M Products' Pressure Washing Gun provides an alternative to expensive self-contained washers and also accepts a standard garden hose for water. A quick-coupling siphon attachment allows easy application of solvent or cleaning fluid to a problem area. After soaking the area, the user blasts away with 250 PSI of hot water or a hot water and air combination to remove all dirt and debris.

There are two versions of the Gun the only difference being how the air is activated. Some prefer the simplicity of the DM-100 valve model, yet the DM-200 trigger model is our most popular item. We also make nozzle extensions and a flushing adapter to round out a complete line of accessories common to both guns.

The company was operated from Pasadena until 1984 when it relocated to Santa Monica, California. Since May 1996, the company brought in new management, which made improvements in product quality and inventory stocking. D&M supplies a number of distributors and directly services many national accounts.
