The stainless steel pro-2300 has everything you need in a vacuum sealer speed: With a powerful double piston pump and seal bar to finish the job in half the time. Flexibility: The extra-long, 15″ seal bar means you can seal a variety of vacuum sealer bag sizes up to 15″ wide. Power: With 935 watts of power, this is one of the most powerful chamber sealers on the market. It even seals through moisture dependability: an extra wide, 5mm seal bar creates a solid, dependable seal every time. Durability: The fan cooled motor is designed specifically for continuous, repetitive use without overheating. Led lights monitor the stages of the sealing process. There are two seal modes depending on the type of sealing you are doing. The automatic mode has a simple one-touch operation, while the manual seal mode allows you to control the amount of vacuum pressure when sealing soft foods or delicate objects. The transparent acrylic lid makes it easy to align the bag perfectly for sealing. The power cord is detachable, and fits within a convenient storage compartment.
