AD-31 Spray Hand-Held Applicators
Description
AD-31 spray hand-held applicators use compressed air to
atomize hot melt adhesive. Independent atomizing air and
pattern air control allows adjustment of pattern size, shape
and density.
Features
• Independent controls for atomizing and pattern air utilize one
standard spray nozzle that yields pattern widths ranging from
51 to 203 mm (2 to 8 in.).
• Micro-adjust feature alters material flow at the nozzle orifice.
• Two independently heated and controlled temperature
zones improve temperature stability to minimize the cooling
effect of expanding spray air. Each zone, located in the pivot
sleeve and in the nozzle section, contains a separate heater
and temperature sensor, allowing use of room temperature
compressed air.
• Depending on the applicator, hand-held applicators employ
either a preset thermostatic temperature sensor or a RTD
(resistance temperature detector) sensor. RTD sensing provides
temperature control precision by reducing temperature
fluctuations that negatively affect flow and cause char
formation.
• Hand-held applicators with RTD sensors require an extra
temperature control channel for the hand applicator nozzle
section. Cordsets that connect the control channel to the nozzle
section are available in different lengths to accommodate hose
length.
• A 260 °C (500 °F) overtemperature thermostat in the nozzle
section shuts off heater power in case of abnormally high
temperature conditions.
• A 190 °C (375 °F) thermostat is standard on thermostatically
controlled hand-held applicators. Optional thermostats for
different temperature settings are available for customer
installation.
• Distinctive ever-cool handle provides comfortable operation
and helps reduce risk of burns by containing heated
components and adhesive-flow paths within the hand
applicator body, not the handle. Impact resistant molded shell
extends service life.
• A 90° hose swivel permits ease of movement and limits hose
twisting.
• Hand-held applicators accommodate broad range of Nordson
melters.
