In an air compressor system, which of the following is done with condensed water?

• A. Stored in reservoir
• B. Drained from the system
• C. Recycled condensate
• D. Vent to atmosphere

Answer: (B)

Condensation forms when the compressed air cools, so water collects in receivers and piping. The proper practice is to drain that condensate from the system using drains at low points and in receivers. This removes the water, preventing corrosion, damage, and moisture carrying contaminants into downstream tools. Storing condensate isn’t typical because it can promote corrosion and contamination; recycling condensate isn’t appropriate since it may carry oil and particulates that would pollute the air; venting to the atmosphere releases moisture and pollutants without actually removing the liquid from the system. Draining is the reliable way to keep the system dry and protect equipment.
