Covidien Puritan Bennett 4-075802-SP Printed circuit board for 806 compressor

Covidien Puritan Bennett 4-075802-SP Printed circuit board for 806 compressor

The Puritan Bennett 4-075802-SP Printed Circuit Board is a precision-engineered electronic control assembly designed specifically for the Puritan Bennett 806 air compressor unit that integrates with the Puritan Bennett 840 ventilator system. This sophisticated OEM PCB serves as the primary electronic control module for the 806 compressor, managing motor operation, power regulation, pressure monitoring, and bidirectional communication with the ventilator's Breathing Device Unit (BDU). The board incorporates advanced microprocessor-controlled circuitry that regulates compressor startup sequences, maintains accumulator pressure within specified limits, and provides real-time operational status feedback to the BDU for continuous system monitoring. Manufactured to stringent medical device quality standards by Covidien, this printed circuit board assembly features industrial-grade electronic components rated for continuous 24/7 operation in critical care environments. The PCB interfaces with multiple compressor subsystem components including the motor assembly, pressure transducers, safety interlocks, and the BDU communication port, serving as the electronic nerve center that coordinates all 806 compressor operations for reliable medical air supply to life-support ventilation systems.

Specification of ventilator parts:

Description of ventilator parts: 

This essential electronic control component serves as the operational brain of the Puritan Bennett 806 air compressor system, extensively deployed in intensive care units (ICUs), critical care units (CCUs), neonatal intensive care units (NICUs), operating room recovery areas, and facilities without central medical air supply where reliable compressed air generation for mechanical ventilation is critical. The PCB manages all compressor operations including motor start/stop sequences, accumulator pressure maintenance between 26-50 psig, automatic activation when hospital air pressure drops below 26 psig, and continuous communication with the 840 ventilator BDU to coordinate air delivery with patient ventilation demands. Biomedical engineering technicians rely on this control board during troubleshooting and repair procedures to diagnose compressor malfunctions, motor failures, pressure regulation issues, and communication errors between the compressor and ventilator systems. The 806 compressor with its electronic control PCB provides an independent compressed air source essential for ventilator operation during medical air system failures, making this PCB a critical safety component for uninterrupted life-support ventilation capabilities in healthcare facilities.

Advantage:

Integrated Motor Control: The PCB provides sophisticated motor control functions including soft-start sequencing, speed regulation, overload protection, and thermal monitoring, ensuring reliable 806 compressor motor operation while protecting against electrical faults that could damage the compressor assembly.

BDU Communication Protocol: The board maintains continuous bidirectional communication with the Puritan Bennett 840 ventilator BDU, enabling coordinated air delivery, alarm generation, and system status reporting that keeps the ventilator operator informed of compressor availability and performance.

Automatic Standby Operation: The intelligent control logic maintains accumulator charge during standby mode, ensuring immediate compressed air availability when hospital air supply pressure drops, providing seamless transition to backup compressor operation without patient intervention.

Fault Detection and Protection: Advanced monitoring circuits detect motor faults, pressure anomalies, electrical overcurrent conditions, and communication failures, triggering automatic shutdown and BDU alarm notification to protect both equipment and patients from compressor-related failures.

Continuous Operation Reliability: Designed for 24/7 continuous-duty operation, the PCB components are rated for extended service life in demanding ICU environments, minimizing unplanned downtime from electronic component failures.

OEM Compatibility Guarantee: As a genuine Covidien OEM replacement part, the 4-075802-SP ensures exact electrical specifications, communication protocols, and mechanical fit compatibility with the 806 compressor assembly.
