 Hot air can be used successfully in a wide variety
of processes and techniques. Depending on the required temperature,
static and dynamic pressure, air velocity and air volume, the appropriate
hot-air blowers or heaters with suitable blowers can be combined
and installed. By the use of various nozzles and reflectors, the
hot air can be concentrated, spread or even sharply reduced without
any significant loss of temperature. The temperature of the hot air can, depending on the model, be precisely controlled from ambient temperature to max. 900°C by means of built-in or external electronic controls.
For special applications (external control of heating power or
remote measurement of the temperature of the hot air stream) additional
adjusting control devices are available. Use only nozzles and accessories
from the LEISTER range. Improperly constructed nozzles can affect
the hot air stream, and therefore, the efficiency of the tool. If
the air flow falls short of the specified minimum air flow (see
technical data of appropriate heaters), the power supply must be
simultaneously interrupted because otherwise, the heating element
burns out. All tools, depending on the model, are equipped for
use with voltages 120V / 200-230V / 380-400V / 440-480V (50/60Hz)
and carry international approval marks. Contact Malcom Company
for expert advice and information on the range of Leister tools
and accessories available.
