Fast, Efficient Sampling for Stored Grain Quality Management

The Vac-A-Sample® Pneumatic Sampling System provides a fast and reliable way to evaluate grain condition throughout the entire storage bin. Designed for probing grain up to 60 feet deep, it helps identify moisture pockets, insect infestations, mold growth, hot spots, and aeration concerns before they become costly problems.

Using pneumatic vacuum technology, the system continuously draws samples from deep within stored grain, allowing operators to assess grain quality without unnecessary grain movement or labor-intensive sampling methods. Two operators can typically complete multiple 60-foot probes in a single workday, reducing sampling time and improving storage management efficiency.

In addition to grain, the Vac-A-Sample® can be used with a variety of dry, free-flowing materials commonly found in agricultural and industrial storage applications.

Key Features

• Samples grain bins up to 60 feet deep
• Quickly detects moisture pockets, mold, insects, and hot spots
• Reduces the need for grain turning and unnecessary handling
• Pneumatic vacuum design provides continuous sample collection
• Helps improve grain storage monitoring and quality control
• Can be used for grain, seeds, meals, and other free-flowing materials
• Supports targeted fumigation and insecticide application
• Modular probe sections allow customization based on storage depth
• Fumigation & Hot Spot Treatment

The Vac-A-Sample® is also an effective tool for localized fumigation and insect control. Once a problem area is identified, operators can insert the probe into the affected zone and apply insecticides or fumigation tablets directly where treatment is needed. This targeted approach helps reduce chemical usage while avoiding the need to treat an entire storage structure.
