The choice between an oil pump and a dry pump vacuum sealer ultimately depends on your specific needs and preferences. Oil pumps are known for their high vacuum level and are often favored in industrial or heavy-duty applications. Dry pumps, on the other hand, offer the advantage of being oil-free, which can be appealing for those concerned about potential oil contamination or maintenance requirements. Ultimately, it's important to consider factors such as intended usage, budget, and personal preferences when determining which type of vacuum sealer is better suited for your needs.
