service or advice, please contact any of our factory outlets which are listed on page 15.
SPRAY GUN OPERATION
LEMMER Electric Airless Spray Guns operate with a high pressure piston action pump, which
creates the pressure needed to finely atomize all sprayable materials. The piston movement is
obtained through the use of a 120 V, 60c/s oscillating motor. The resulting 120 piston strokes per
second are combined with a durable one-way valve to draw in paint, pressurize the paint, and
spray it out in a finely atomized mist. Since the mist is airless (no air used to convey the paint),
very little overspray is produced. The results are smooth finishes, minimal paint loss, and very easy
clean-up. Since many of today's paints have abrasive qualities, the LEMMER guns have been
specially designed to handle these tough paints. Extensive use of ceramics, and a specially
grooved tungsten carbide piston, make these airless spray guns extremely durable. Ceramics have
the advantage of being harder than tungsten carbide, as well as having very low friction values,
resulting in much less wear when compared to conventional materials.
