Lubricated Vane Medical Vacuum System with Premium NFPA Controls Rev. 2/27/14 GENERAL The Powerex medical vacuum system is designed to create a suction system to remove unwanted fluids or gases from hospital/ laboratory working areas. The medical vacuum system package is compliant with the NFPA 99 requirements for Risk Category 1 systems. Each system is completely tested before shipment and includes: Multiple vacuum pumps and associated equipment AMSE air receiver Medical control panel Each pump is factory piped to a common intake manifold. Vibration isolation pads are included with the system. ROTARY VANE VACUUM PUMP The medical vacuum pumps shall be of the rotary vane air-cooled design. Each vacuum pump shall be directdriven through a shaft coupling by a TEFC electric motor. Belt drives shall not be permitted. The vacuum pumps shall be mounted on vibration isolators. Each vacuum pump shall be air-cooled and have absolutely no water requirements. Each pump is equipped with a 10 micron inlet filter for removal of particulates. Lubrication shall be provided by an integral, fully recirculating oil supply that is filtered by an automotive-type, spin-on oil filter. Non-recirculating (once-through) or partial re-circulating oil supply systems shall not be permitted. Each vacuum pump shall be capable of operation with ISO 100 viscosity oil. The oil separation systems shall be integral and shall consist of no less than three stages of internally installed oil and smoke eliminators through which the exhaust gas stream must pass. This system shall consist of bulk separation, oil mist elimination, and smoke elimination, and shall be capable of removing 99.9+ percent of all oil and smoke particles from the exhaust gas stream. Each vacuum pump shall include a built-in, antisuck-back valve, mounted at the pump inlet, and three sliding vanes. MOTOR The motor is continuous duty, C-face, TEFC, suitable for 208-230, or 460V, 3 phase, 60 hertz electrical operation. AIR RECEIVER The system shall include an ASME rated air receiver. The tank shall be equipped with a vacuum gauge, a sight gauge, by-pass valves, and a manual drain. PREMIUM NFPA CONTROL PANEL The control system provides automatic lead/lag sequencing and automatic alternation of all pumps in order to equalize the amount of usage among the available vacuum pumps. The Premium NFPA Control Panel shall include a gateway server card and all features listed below: PLC controller and a color touch screen panel which displays the operating status of the unit. Building automation communication gateway with BacNet® protocol and Web server features. Web servers features include email notifications in case the system is in alarm or has achieved one its maintenance intervals and requires service. Ethernet port for connection to BacNet® server or direct connection to facility Ethernet for viewing of system operations and status via device IP-address UL508A listed control panel in a NEMA 12 enclosure. The panel door will include: the color touch screen, an audible and visual alarms with an acknowledge button, and an HOA switch for each pump Magnetic starters Vacuum transducer for process control Single point power connection Redundant 120Vac control transformers with fused primary and secondary protection System overload trip, high temperature conditions or maintenance intervals for the pump will result in visual and audible alarms AVAILABLE OPTIONS Oil temperature gauges Internal tank lining for corrosion resistance Powerex– 150 Production Drive – Harrison, OH – 45030 – Ph: 888-769-7979 - www.powerexinc.com SR4452 02/14
