Overview

The Samson 039-3720 is a professional-grade oil suction and drain combo unit built for automotive service environments where efficiency and cleanliness matter. By combining both suction extraction and gravity collection into a single 27-gallon unit, it eliminates the need to maintain separate pieces of equipment for different drain scenarios. The telescopic collection bowl adjusts to meet various vehicle undercarriage heights, while the extension bowl insert and anti-splash grid work together to keep the workspace clean during gravity draining.

A standout feature is the 10-quart transparent chamber, which gives technicians a clear view of the waste oil as it's collected. This allows for quick visual inspection of oil condition — checking for coolant contamination, excessive metal particles, or other warning signs — before the oil passes into the main tank. At 90 pounds and measuring 36 x 24 x 24 inches, the unit is substantial enough to remain stable during use but is best suited for shops that can dedicate permanent floor space to it.
