It is compatible with all horsepower ratings — from small single-phase shop units to large industrial compressors — and installs at the existing tank drain port as a direct upgrade to the manual petcock.\u003c\/p\u003e\n\n\u003cp\u003eWater in a compressor tank is one of the most common causes of accelerated tank wear and downstream air quality problems. Every reciprocating compressor pulls moisture-laden air in with every stroke. That moisture condenses in the tank and accumulates at the bottom. Without consistent draining, you get internal rust that shortens tank life, water in the air lines that saturates downstream filters and damages pneumatic tools, and eventually a compressor tank that fails before the pump does. Manual draining works when it actually gets done — the SDV03S makes sure it happens on schedule, automatically, without any operator involvement.\u003c\/p\u003e\n\n\u003ch3\u003eHow It Works\u003c\/h3\u003e\n\u003cp\u003eThe SDV03S uses a solenoid valve controlled by a programmable electronic timer. You set the interval (how often the valve opens) and the duration (how long it stays open). At each interval, the timer triggers the solenoid, the valve opens, accumulated condensate gets expelled from the tank bottom, then the valve closes and the timer resets. In high-humidity environments you might set it to drain every 30–60 minutes. In a dry climate with lighter use, a 4–6 hour interval may be sufficient. The key is that the decision is made once at installation, not every day.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e115 Volt AC Operation:\u003c\/strong\u003e Standard single-phase shop power — connects to the compressor's electrical panel or a standard 115V outlet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eElectronic Timer Control:\u003c\/strong\u003e Programmable interval and open duration — adjust drain frequency and duration to match your ambient conditions and compressor duty cycle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUniversal HP Compatibility:\u003c\/strong\u003e Rated for use with all compressor horsepower ratings — the same valve works on a 5 HP shop compressor or a 25 HP industrial unit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTank Port Installation:\u003c\/strong\u003e Threads into the tank's existing drain port — replaces the manual drain petcock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSolenoid Valve Design:\u003c\/strong\u003e Electrically actuated — opens on timer signal, closes when cycle ends, no mechanical actuation or manual intervention required\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEliminates Manual Draining:\u003c\/strong\u003e Set the timer once; the SDV03S handles condensate removal on every cycle without anyone having to remember to do it\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e SDV03S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Voltage:\u003c\/strong\u003e 115 Volt AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eControl Type:\u003c\/strong\u003e Electronic timer (interval and duration programmable)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHP Compatibility:\u003c\/strong\u003e All HP ratings\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Point:\u003c\/strong\u003e Tank drain port\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Cast Air (Castair)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrice:\u003c\/strong\u003e $119.43\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSDV03S vs. SDV03M — Which Version Do You Need\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSDV03S (this product)\u003c\/strong\u003e — 115V standalone field-install version.
