coin cleaner

The machines in the results operate at several common frequencies, including about 40 kHz, 42 kHz, 45 kHz and 48 kHz.

Reported tank sizes range from smaller units around 500–650 mL up to larger cleaners with about 2.0–2.5 L (2000–2500 mL) capacity.

Many models offer multiple preset cycles. Examples from search results include presets such as 90, 180, 280, 380 and 480 seconds, and one-touch timers with options like 90/120/180/240/300 seconds.

Degas or degassing modes remove trapped air bubbles from the tank water to improve cavitation and cleaning efficiency. Some units offer stronger or dual-power degassing to improve cleaning in hard-to-reach areas.

Cleaner tanks are commonly made from stainless steel; some listings specifically reference 304 stainless steel construction.

Noise levels vary by model; at least one listing advertises sound below 60 dB. Many units also auto-shut off after a preset cycle to protect items and the machine, but exact noise ratings and shut-off behaviors differ between models.
