HA-500 Hot Air Bag Sealer

The Doboy HA-500 is a rugged industrial hot air sealer.  It is a new & improved version of Doboy's time-tested Model HA-720.

The HA-500 is designed to seal pillow style polyethylene bags.

Like its predecessor, the HA-500 is especially effective in corrosive or gritty packaging environments because it uses hot air for heating.

Typical bagging applications include Salt, Firewood, Stone, Mulch, Soils, Wood Pellets, Hot Patch, Cold Patch, Asphalt, Fertilizer, & Chemicals.
