91194 specifications

Harbor Freight Tools is renowned for providing quality tools at affordable prices, and one standout product from their extensive lineup is the 91194 heavy-duty ultrasonic cleaner. This device is designed to provide efficient and thorough cleaning for a wide range of items, making it an essential tool for both hobbyists and professionals.

The Harbor Freight 91194 ultrasonic cleaner is equipped with a robust 40kHz ultrasonic frequency that enhances cleaning efficacy by creating millions of microscopic bubbles in the cleaning solution. When these bubbles implode, they generate powerful cleaning action that reaches into tiny crevices and complex geometries. This allows for a level of cleanliness that manual scrubbing simply cannot achieve.

One of the key features of the 91194 is its spacious tank that can accommodate various items, from jewelry and intricate automotive parts to delicate electronics and tools. The tank has a generous capacity of 2.5 liters, making it perfect for cleaning multiple items simultaneously. Its stainless steel construction not only ensures durability but also resists corrosion, enhancing the longevity of the unit.

This ultrasonic cleaner also comes with an adjustable temperature setting, enabling users to customize the cleaning process based on the specific materials being cleaned. The built-in heater warms the cleaning solution, which can significantly boost cleaning power and efficiency. This is especially beneficial when dealing with greasy or heavily soiled items.

Another characteristic that stands out is the user-friendly control panel. It features simple buttons for setting the timer and temperature, making it accessible for users of all experience levels. The digital timer can be set for up to 30 minutes, providing flexibility depending on the level of dirt on the items being cleaned.

Safety is also a consideration with the 91194, as it is designed with built-in safety features to prevent overheating. Additionally, the ultrasonic cleaner operates quietly, ensuring minimal disturbance during use.

In summary, the Harbor Freight Tools 91194 heavy-duty ultrasonic cleaner combines powerful cleaning technology with user-friendly design and versatility. Its robust construction, adjustable temperature settings, and efficient cleaning action make it a valuable addition to any workshop or home, whether for automotive, jewelry, or general cleaning needs.
