Recommended range. Dry, regulated, non-lubricated air required
for consistent applicator operation. Module performance and
durability will be negatively affected if operated outside the
recommended range. Volumetric air requirements will vary with
applicator configuration and application.

Specify and order nozzles separately.
NOTE: Use H-20 applicators for high-flow, intermittent applications.
They are excellent for dispensing high viscosity and filled
materials. H-20 cartridge design provides approximately four
times the life of previous design when used with packaginggrade
hot melts.
