Series AD-31 Handguns

Compact, lightweight
handguns offer a wide
range of pattern
capabilities and durable
design for manually
operated adhesive and
sealant applications.

Nordson® Series AD-31 handguns
combine efficient design and reliable
performance for manually dispensing
hot melt adhesives, sealants and
other thermoplastic materials. The
wide selection of models satisfies a
full range of applications, including
packaging, assembly and sealing
operations.
The series consists of various models for producing solid or foamed
extrusion beads, spray patterns and
swirl spray. For handling high-viscosity
or filled materials, AD-31 LBS
Extrusion handguns incorporate a
large ball-and-seat and larger flow
paths.
Designed with the operator in mind,
lightweight AD-31 Extrusion and
Swirl handguns weigh less than two
pounds.
A distinctive “ever-cool” handle
contains no heated components or

adhesive-flow paths that could cause
discomfort to the operator. Heated
gun components are totally enclosed
within the exterior gun shell, helping
to reduce the risk of burns.
Capable of standing up to the most
demanding applications, AD-31
handguns feature an impact-resistant
molded shell for extended service
life. To eliminate hose twisting,
AD-31 Extrusion and Swirl models
feature a 360-degree swivel
connector.
A broad product range allows
compatibility with most Nordson
applicators and drum melters.
Selection depends on the applicator
specified, as well as pattern desired,

material viscosity and output rate
requirements. Depending on the
applicator design, handguns employ
either an RTD sensor (resistance
temperature detector) or a preset
thermostatic temperature sensor.
RTD sensing reduces temperature
fluctuations that could negatively
affect flow and cause adhesive char
formation. A wide operating temperature range of 130° to 450°F (55° to
230°C) provides additional application
versatility.
