The new pneumatic impulse foot sealers are unique, because the actual sealing pressure is strong, consistent and controllable. Helpful in sealing applications where time and pressure need to be regulated. These unique sealers are quieter in that the clanging noise found in most other automatic sealers is reduced. These sealers come with a foot switch for operation. Pneumatic Foot Sealers are manufactured in ISO-9001 certified facilities.
