AC&R Components S-6411 Refrigerant Muffler 1-1/8 Inch

The Henry Technologies S-6411 is a 1-1/8 inch discharge-line muffler designed to quiet refrigeration and HVAC compressor discharge by attenuating high-frequency pulsations. It features a carbon steel body and an internal baffled chamber that smooths refrigerant flow with minimal pressure drop, helping protect downstream components and reduce noise in machine rooms. The unit measures about 12.75 inches (324 mm) in length and weighs roughly 6.0 lb (approximately 2.7 kg), with CE-marked variants available as S-6411-CE for compliant installations. It is intended for high-pressure commercial refrigeration and HVAC systems and connects to a 1-1/8 inch line, making it a compact after-discharge silencer that mitigates pulsations without bulky footprint. Temperature operating range is 32 to 249 F, enabling reliable service across typical refrigeration environments while maintaining acoustic performance.
