Description
The NPE-LF10 and NPE-HF10 are corona-type automatic electrostatic
powder spray guns. The NPE-LF10 is used in low-to-medium volume
powder coating applications. The NPE-HF10 is used in high volume
applications. A typical application is pipe coating, where the powder is
sprayed onto hot pipe at close range. To allow the spray gun to function in
these conditions, cooling air is circulated through the spray gun.
The NPE-LF10 and NPE-HF10 spray guns are the same except for the
powder tube and nozzles, which are interchangeable. Conversion kits are
available, one to convert a LF10 to a HF10, and one to convert a HF10 to a
LF10. Different pumps and hoses are used with each version, and must be
ordered separately.
The spray guns are used with Nordson model EXP-100 or -100M
electrostatic power units. These power units can put out up to 100 kilovolts.
The spray guns are connected to the power unit by electrostatic cables.
Cables are available in 8- or 16-meter (25- or 50-ft) lengths. Venturi-type
powder pumps supply powder to the spray guns.
