If your compressor is running near a customer waiting area, office space, or any environment where noise is a concern, the SA100 threads directly onto the pump's air intake port and significantly reduces the characteristic intake roar that comes with every piston stroke.\u003c\/p\u003e\n\n\u003cp\u003eCompressor intake noise is distinct from mechanical noise — it is the rapid air pulse created by the intake valve snapping open on every suction stroke. Without a silencer, that pulse radiates directly into the surrounding space. The SA100 uses internal acoustic baffling to absorb and diffuse that pulsing airflow before it becomes audible noise, with no restriction to intake airflow capacity when the filter element is clean and properly maintained.\u003c\/p\u003e\n\n\u003ch3\u003eHow Intake Silencers Work\u003c\/h3\u003e\n\u003cp\u003eEvery piston compressor draws in a sharp burst of air on each intake stroke. On a two-cylinder pump running at 900 RPM, that's roughly 900 intake pulses per minute — enough to generate a continuous, audible drone in the 100–500 Hz range that carries through walls and shop floors. The SA100 uses a combination of acoustic damping material and internal baffling to absorb that pulse energy before it exits the intake. The result is a measurably quieter compressor with no impact on performance.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDirect Intake Mount:\u003c\/strong\u003e Threads directly onto the compressor pump's intake port — standard NPT threading for Cast Air pump intake configurations\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAcoustic Noise Reduction:\u003c\/strong\u003e Internal baffling dampens intake pulse noise on each compression stroke\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNo Performance Penalty:\u003c\/strong\u003e Designed to allow full intake airflow — does not restrict pump output when filter element is clean\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCast Air OEM Part:\u003c\/strong\u003e Sized and threaded to match Castair pump intake port specifications\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eServiceable:\u003c\/strong\u003e Internal filter element can be inspected and replaced — maintain airflow by keeping the element clean\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle-Unit Purchase:\u003c\/strong\u003e One silencer for one pump intake; for C2 or C3 pump configurations with two intakes, see SA100x2M or SA100x4M\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 SA100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Compressor intake noise silencer \/ intake filter-silencer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 1 unit (single)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread:\u003c\/strong\u003e NPT — confirm your pump's intake port size before ordering\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 18.58\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003eNote: Thread size and port diameter specifications — call 866-217-0063 to confirm the correct fit for your specific Cast Air pump model before ordering.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003ch3\u003eAvailable Configurations — Silencer Options by Pump Type\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSA100\u003c\/strong\u003e — Single silencer, unmounted.
