Current Standard Model: SC2704XPM | Old model: SC3706PM (100% Drop-in Backward Compatible)
High-torque micro diaphragm air pump engineered for intelligent massage chairs, zero-gravity recliners, and therapeutic pneumatic airbag systems. Delivering >1.5 L/min airflow, >68 kPa (>510 mmHg) positive pressure, <3 mmHg/min airtight holding, and 60,000 duty cycles within an ultra-compact 45.1mm body footprint.
Engineered for Multi-Airbag Massage Chairs & Pneumatic Compression Therapy
-

Deep Positive Pressure (>68 kPa / >510 mmHg): Generates powerful pneumatic thrust to overcome human body weight resistance, delivering deep-tissue acupressure and firm limb wrapping without pressure drop.
Superior Airtightness (<3 mmHg/min Leakage): Advanced elastomeric check valves ensure rock-solid pressure holding during sustained squeeze phases, preventing airbag softening.
60,000 Heavy-Duty Pulse Cycles: Certified across 60,000 cycles (10s ON, 2s OFF, 5s EXHAUST), providing multi-year maintenance-free durability under frequent massage duty cycles.
High Energy Efficiency (<150 mA at 24V): Consumes minimal electrical current, significantly reducing power supply load and heat dissipation when multiple pumps operate in parallel.
Compact 45.1mm Body Length: Featuring an ultra-short 45.1mm envelope with a ø27.0mm mounting flange, SC2704XPM fits easily into crowded manifold valve boxes and chair armrest cavities.
Low-Vibration Acoustic Performance (50–57 dB): Precision multi-chamber dynamic balancing restricts operational noise well below 65 dB, maintaining a quiet, soothing relaxation ambiance.

Application Focus: Pneumatics in Massage Chairs & Ergonomic Recliners
1. Intelligent Multi-Airbag Massage Chairs (Shoulder, Arm & Calf Compression)
Luxury zero-gravity massage chairs utilize dozens of layered airbags to simulate rhythmic human kneading. SC2704XPM delivers >68 kPa positive pressure to overcome user body weight and inflate airbags forcefully around arms, shoulders, and calves. Its steady >1.5 L/min flow provides seamless inflation cycles, while superior internal sealing preserves pressure during holding sequences for therapeutic muscle release.
2. Ergonomic Office Chairs & Automotive Lumbar Support Systems
Active dynamic seating integrates pneumatic lumbar bladders that periodically adjust posture. With a short 45.1mm body and low < 150 mA current draw at 24V, SC2704XPM integrates neatly into seat backrests without taking up ergonomic space or causing thermal accumulation.
3. Physical Therapy Compression Boots & Circulation Recovery Systems
Sequential leg compression devices demand precise inflation ramps and tight holding phases. SC2704XPM offers <3 mmHg/min airtight containment and a 60,000-cycle endurance rating, ensuring dependable clinical and home care performance.
