Series AD-31 Extrusion
Hand-Held Applicators
Description
Series AD-31 extrusion hand-held applicators are
compact, lightweight hand-held applicators that provide
a wide range of pattern capabilities. These durable handheld
applicators combine efficient design and reliable
performance for manually dispensing hot melt adhesives,
sealants and other thermoplastic materials. A wide
selection of models satisfies a full range of applications.
Features
• Compact, lightweight design weighs 0.80 kilogram (1.75
lb) for handling ease.
• 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 360° swivel connector eliminates hose twisting.
• 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.
• Choice of standard and extended nozzles with varying
orifice diameters meets numerous deposition requirements.
Specifications
AD-31 Hand-Held Applicator with DuraBraid Hose
• Hand-held applicators accommodate broad range
of Nordson melters and hose diameters.
• The AD-31 LBS uses a large ball-and-seat and
larger flow paths for handling high-viscosity or
filled materials.
• Models used with gear-pump drum melters have
a microswitch in the hand applicator handle to
control the motor clutch and regulate adhesive
flow.
