There are two main types of striping machine manufacturers: conventional and airless. In a conventional paint striping machines, parking lot striping machines compressed air fed to the paint reservoir forces paint down through a hose to the spray nozzle mounted underneath the machine. Line striping machines the air changes the stream of paint into a spray that marks the lines and stripes on the ground. Another hose carries air to a can of water or paint thinner (depending on whether the paint is latex or oil-based) that can clean out the nozzle of the line marking machines spray nozzle should it become clogged. This hose bypasses the main paint line so that the paint itself is not diluted, ensuring that the lines are even and consistent. Each air and paint hose has a valve that can be adjusted to control pressure and power. Airless striping machines
do not use air compressors at all. Instead, a hydraulic pump draws paint through a suction tube to the nozzle which is a very small slit. Road marking equipment the pressure of the paint being forced through the hole causes it to fan out into a spray pattern. There thickness of the paint and the width of the spray cannot be adjusted because there is no air that allows for it. Airless striping machines are either off or on full power. Striping Machine Supplier the slit is also prone to clogging and must be cleaned manually.
